Our take on the Cambridge Audio Topaz SR20

Stereo music lovers, meet the Cambridge Audio Topaz SR20. An outstanding value considering its audiophile-grade parts and construction, this receiver has connections for eight different audio sources, including three digital inputs. The inclusion of a Wolfson digital-to-analog converter means clear sound with depth and detail from streaming media players, Blu-ray players, and more. A direct connection for a turntable lets you enjoy your music on vinyl without the addition of a phono preamp, and the versatile front-panel minijack connector gives you an easy connection for most any kind of MP3 player or portable device. Two pairs of speaker outputs let you drive a second pair of speakers or bi-wire compatible speakers for optimal performance. And a connection for an optional powered subwoofer lets you enjoy the full sound of a 2.1 stereo system.

Amazing sound, pure and simple

Rock-solid performance

At the heart of the SR20's powerful sound is a Class AB amplifier fed by a toroidal transformer that makes its 100 watts per channel sound like significantly more. Every time Cambridge reps come here to share demos with us, I'm blown away by the room-filling sound coming from what seems a modestly-powered amp, spec-wise. Whether you pair the SR20 with floor-standing speakers or compact satellites, your listening room will be filled with incredibly pure, detailed sound. And to top it all off, the receiver's stylish and functional metal casing provides acoustic damping to reduce distortion caused by vibration for the cleanest possible performance.

  • 100 watts x 2 into 8 ohms (20-20,000 Hz) at 0.15% THD

Great sounding stereo amp!

Will from Cohoes, NY on 12/7/2018

Crutchfield Customer Review (What's this?)

I went with this Cambridge Audio Receiver for three reasons; good reviews, phono preamp and teroidal transformer. This amp sounds fantastic with my polk audio speakers. Very warm sounding music much like the vintage Kenwood receiver that it replaced. Also, I find no need to add a subwoofer but have this capability down the road.

Pros: Plenty of power and sounds great.

Cons: None so far.

Perfect receiver for a HiFi system - love it!!!

Pros: Easy set-up,

Cons: None

Not a happy camper

Don from Homewood, IL on 6/24/2018

I purchased this product, not from Crutchfield, 2 1/2 years ago. While the performance is good the dependability is not acceptable. It is failing for a second time - the first because of a bad power cord, under warranty. Yet to find out what what this problem is. Performs well when it works

Pros: Performs well when it works

Cons: Doesn't always wort

Crutchfield Customer Review (What's this?)

My first ca purchase. Has plenty of power. Looks good and built well.easy hookup. Seems like it will be a good unit.very pleased.

Pros: Very good unit

Cons: None

Nice clean unit

Jerel from Boulder Creek, CA on 5/20/2018

Crutchfield Customer Review (What's this?)

I chose this unit partly for the form-factor; taller units would not fit my cabinet. Setup is straightforward. I particularly like the speaker terminals, they are easy to use, easy to avoid fray wire short circuits, and firmly connected. Sound quality on phono input (my main purpose) is excellent. I don't use the radio tuners.

Pros: Low-profile chassis, easy setup, good speaker connections, clean sound.

Cons: Does not address more complex surround-sound configurations than stereo with sub-woofer, if that is needed.

Well built workhorse of an amp!!

Daron from Vista, CA on 4/8/2018

Crutchfield Customer Review (What's this?)

Exceptional value in a very well built albeit basic amp. This is a no frills workhouse, controls are very basic but it has everything you need. Dedicated phono input was a big plus as I sought to get back into vinyl. Features multiple speaker options to include subwoofers, bi-wiring capabilities, digital/optical inputs, etc. Very utilitarian but everything I needed in a powerhouse amp that I will likely own for a long time. Cambridge audio has a well deserved reputation for building professional grade components and this is a perfect example. If you are looking for a basic, reliable, but powerful amp for less than $500 this is a no-brainer. It's internals (like high quality toroidal transformers) rival those of amps costing upwards of $1000 plus. Spend your money on speakers and buy this with absolute confidence!!

Pros: Superbly affordable. High quality design. Simple, easy to use controls. Versatile - covers all basic hi-fi requirements/options

Cons: Can't think of any at the moment!!!

Cambridge Audio Topaz SR20

Crutchfield customer from Fishers, IN on 3/23/2018

Crutchfield Customer Review (What's this?)

Great receiver, plenty of power to make my 4 ohm speakers sound the way they should. Plenty of bass, without tweaking the controls. Never had Cambridge before but I would buy again.



Superb value

Crutchfield customer from Fayetteville, NC on 1/28/2018

Crutchfield Customer Review (What's this?)

I'm quite pleased with my Topaz SR20 as the replacement for my old Philips 950 (RIP), and I'm considering other Cambridge Audio products. The Crutchfield team was great, and I now consider them my primary source for future purchases. Thanks.



Cambridge Audio Topaz SR20

Crutchfield customer from Myrtle Beach, SC on 1/28/2018

Crutchfield Customer Review (What's this?)

Very nice receiver. Impressive sound and plenty of power even though I am still breaking it in and haven't totally cranked it up yet.Easy to set up and hook up. Great choice for a music lover who only needs a 2 channel power supply..



Not a fan of the Cambridge sound

Nick from Canton, Oh on 1/12/2018

Crutchfield Customer Review (What's this?)

I'm simply disappointed with this receiver. I've been looking for a quality "stereo" receiver with 80-100w rms x62, simple design, has some weight to it and was within my max budget. The SR20 had everything I wanted so I decided to get it. While taking it out of the box and hooking it up I was impressed. The receiver had a nice heavy feel to it with an all metal case and a thick metal faceplate. I personaly liked how bright the display was (my vision isn't the best so I hate dim dispjays). Despite some complaints about the speaker terminals in the reviews, I found them to work just fine (My banana plugs plugged in nice and tight). Now the disappointing part, the sound. While I found the sound to be very very clean, it sounded very "flat" and "lifeless." The SR20, even with the bass level set to maximun, has weak bass output/punch. I even tried multiple audio sources with the same results. I know what my floor standing speakers are capable of so its not the speakers. My 15 yr old 60watt x2 Sony receiver had way more punch and full rich dynanic sound. Another thing I don't like about the SR20 is you have to spin the volume knob many times around to increase the volume. The fact that the S/N Ratio for the SR20 is in the mid 80db's does not please me either. Bottom line, I just don't think the Cambridge Audio sound is for me. Crutchfield is the best, with no questions asked they are sending me a different receiver.i'm going with the Onkyo tx-8270

Pros: Well constructed. Heavy, clean simple design

Cons: Bass level output was disappointing (even with bass setting maxed out). Poor S/N Ratio.

Quality amplifier

Jim from PA on 12/26/2017

Crutchfield Customer Review (What's this?)

Great build quality for the price. Good sound with ample power. First Cambridge Audio product I have purchased and would consider buying additional components based upon my experience so far.

Pros: Plenty of power Great build quality Easy to use

Cons: Backlit remote would be nice.

Great sound, easy to use

Josette from Ninety Six, SC on 12/24/2017

Crutchfield Customer Review (What's this?)

Do yourself a favor and upgrade to a product from a company that specializes in sound. I was looking for great sound and this receiver is phenomenal. I use it in my office, where 2 channels was all I needed and it is exceptional at any sound level, paired with ELAC Debut F5 speakers. Amazing! It was easy to set up and operaiotn is intuitive and the remote is easy to figure out.

Pros: Great sound Easy to set up Easy to use

Cons: Small print on remote buttons - people over 40 need reading glasses to see

Great for audiophile buff!!!

Mike from Blue Springs, MO on 11/8/2017

Crutchfield Customer Review (What's this?)

This powerful amplifier provides a robust boost of energy to my Paradigm floor standing speakers.

Pros: Sophisticated, simplistic, design.

Cons: Not real sure yet where all of the hookups on the back go where?

Simple and powerful.

Chris from Charlottesville, VA on 10/18/2017

Crutchfield Customer Review (What's this?)

If you want a very direct stereo receiver, this is it. No frills, bells or whistles. Just pure and solid performance. I will say the remote feels very slapped together at the last minute. I also like the subwoofer output and moving magnet phono input. The dual optical inputs are very nice as well.

Pros: Direct and straight forward. Very easy to use. Subwoofer output. MM phono input for turntables.

Cons: The remote feels unfinished.

Cambridge Audio Topaz SR20

Crutchfield customer from North Bergen, N.J. on 10/17/2017

Crutchfield Customer Review (What's this?)

Straight up clean sound. No bells and whistles. Perfect for an old school audiophile on a budget.


Cons: Can't shut off the display which can be annoying when listening to the radio. I just keep it covered.

Great Sound

Joel from Gonzales, LA on 10/9/2017

Crutchfield Customer Review (What's this?)

Easy to set up and control. Just what I needed.

Pros: Good all around

Cons: No HD inputs

Tracie from Dayton, OH on 8/19/2017

Crutchfield Customer Review (What's this?)

After tons of research I went with the SR20 and am glad I did. Easy navigation, great sound and quick set up. I haven't used the remote yet and not sure I will but it's a nice option. Shipped fast and well-packaged!

Crutchfield customer from Durham, NC on 7/2/2017

Excellent. More than handles all of my stereo components, simple straight forward controls and produces a superb sound.

Pros: Excellent receiver.

Cons: None

Bill from Warwick, New York on 6/14/2017

Crutchfield Customer Review (What's this?)

Just simply awesome. Endless power, clean all the way up. Tuner sharp, controls simple and defined. Sleek and awesome looking display both day and night. Can't be happier!



Plenty of power and clean sound!

Dave from Charlotte Hall MD on 5/18/2017

Crutchfield Customer Review (What's this?)

Not a lot of bells and whistles but if sound quality is what you are looking for then this is the one! I hooked this receiver up to a pair of Klipsch RP 280 F speakers and just purchased the Klipsch R-115SW sub. I was just looking for a system to stream my music on and nothing more. Rich sound and plenty of power! I could not be happier!

Pros: Powerful clean sound.

Cons: None yet!

Good sound for this price

Patrick from Plano, TX on 5/13/2017

Crutchfield Customer Review (What's this?)

This unit perfect fit my requirements I'd surround systems for too long Now more simple to handle actually quality of music has improve




Charles from Marshfield, WI on 5/2/2017

Crutchfield Customer Review (What's this?)

Was disappointed. There was no subwoofer output. Everything else worked great, good sound. Still waiting for a replacement. Was told it might be some time before it get it, it's on backorder.

Pros: Sound output was very good.

Cons: No subwoofer output.

Powerful receiver for all your listening needs.

John from Simi Valley, CA on 4/16/2017

Crutchfield Customer Review (What's this?)

This is a very nice stereo receiver, good reception and high output! I mean its a monster, with power galore, the first speakers I tried were very efficient Bose and well okay, Speaker upgrade covered and love this unit. For a Hi fi entry level receiver, that offers a nice phono pre-amp input and high quality DAC at this price? Cambridge quality, pairs nicely with the CXC transport for your CD's. Also, hats off to Crutchfield, great service, delivery was fast and everything came in top notch condition!! Thank you!!

Pros: Great price Great sound Huge Power Digital and Analog inputs A++

Cons: What's up with the speaker inputs? Hiding the banana plug connectors, not able to use spades, when I first got it, thought it was only bare wire set up.

great sound

david from Truckee, CA on 3/14/2017

Crutchfield Customer Review (What's this?)

great receiver for the price. out performed many other recievers that I have tried. it puts out a lot of sound. only problem the inner fan started to make noise after 2 days . sent it back to give the marrantz sr6010 a try.

Pros: great sound

Cons: faulty cooling fan

Music has never sounded better

Martin from Bethesda, MD on 3/5/2017

Crutchfield Customer Review (What's this?)

This receiver drives some Harbeth C7ES3 speakers in a roughly 13' x 20' room. This pairing delivers a clean and well defined sound with an excellent soundstage. It's a huge improvement over the Yamaha R-S700 it replaces in every respect. A really nice feature of the SR20 is its superb DAC, which enables me to play streaming Tidal HiFi, FLAC audio files and CDs via my Windows laptop (using an optical Toslink cable). Music has never sounded better! The FM tuner does a good job locking in signals from my urban location using the supplied antenna. One word of caution is that while the SR20 sounded good out of the box, there was initially some high frequency brightness, which thankfully went away after about a week. It's been two weeks now and I can't imagine getting better sound from my system.

Pros: Excellent sound quality and a superb DAC

Cons: Took a week of burn in to deliver its full potential

Bach would love this set up

bob from Jackson, TN on 1/15/2017

Crutchfield Customer Review (What's this?)

Great amp for the small price. Full function remote that works from most angles. Easy set up and hook ups. Excellent sound. I pair this with a set of Polk audio speakers and Onkyo multi disc player...sounds GREAT...if Bach could hear his Brandenburg concertos on this setup he would be blown away. Plenty loud for my favorite classic rock. Great bass sound. Very pleased.

Pros: see review

Cons: no display dimmer...glaring omission for this quality amp

Elligant performer

Craig from Clarks Summit, PA on 10/21/2016

Crutchfield Customer Review (What's this?)

This unit is an awesome component for a serious stereo system. It's understated elegance exudes a sophisticated look and sound that is unequaled in this price point. It performs exceptionally well meeting all expectations a serious audiophile would demand. I expect pleasing results from this unit for many years to come.

Pros: Exceptional look and sound

Cons: none

Cambridge Audio Topaz SR20

Crutchfield customer from Kirkland, WA on 8/14/2016

Crutchfield Customer Review (What's this?)

Great little amp for the money. Well designed and good sound quality. The speaker inputs are a little difficult to manage do to space.




David from Covington, Ky on 5/20/2016

Crutchfield Customer Review (What's this?)

Outstanding sound quality with this receiver. My speakers came alive once again. As always Crutchfield's customer service is outstanding. For people that aren't familiar with Cambridge....Do yourself a favor and give this receiver a listen, you wont be disappointed.

Pros: the sound quality that this amp delivers is outstanding. A very nice peace of a high end gear.

Cons: none

A Tank

Omar from los angeles, CA on 3/28/2016

Crutchfield Customer Review (What's this?)

Some vinyl sounds better, some flatter, the mids seem washed out but this might be the speakers. With a pair of B&Ws 686 S2s, the highs and the lows are good but the vocals seem often gone. The simplicity seems great, the quality is mostly awesome; an optical flap cover fell off. I love that it has no clock. Later Depeche Mode and Maria Callas sound great. Early Depeche Mode and Folk not so much. Rock sounds great. Classical is impressive on it. Ozzy sounds a bit too high pitched. I'm adjusting the bass and treble frequently depending on what I'm playing.

Pros: It's beautiful, has a very serious look, simplicity.

Cons: No switch to turn off built-in phono pre-amp. Price. Cheap speaker post caps, optical flap cover fell off.

Step up from my old receiver

David from kennesaw, GA on 3/14/2016

Crutchfield Customer Review (What's this?)

If you are looking for gadgets, then go somewhere else. This receiver is pure with analog and digital inputs, a powerful amplifier, two sets of speakers, and an advanced digital to analog DAC. I have replaced my Marantz 4023 which I've loved for so many years to another system. The SR20 now runs the main with the Swans M1 speakers (best bookshelf speakers I've ever owned).

Pros: Clean powerful Amp Both analog and digital inputs 32bit/192kHz DAC

Cons: No pre-out to add a larger power amp (for future use).

Clean Sound

Cate from Champaign, IL on 1/31/2016

Crutchfield Customer Review (What's this?)

After not having a components system for a number of years, we were really surprised at the wonderful quality of the sound. The Topaz reproduces sound with incredible precision and clarity, and the tuner is a plus. Because we live on a farm, we don't have access to broadband or streaming services. The Topaz picks up our local classical FM station, and listening is an absolute pleasure. Our vinyl and CDs sound better than I thought was possible (especially the CDs). The Topaz is a perfect receiver to use for building a great-sounding system!

Pros: Clean sound. Includes tuner. Uncomplicated to hook up and use. Plenty of power to drive a good set of speakers. Two optical connections. Great digital to analog conversion. Moderately priced.

Cons: Not a good choice for iPod playback.

a great receiver

Crutchfield Customer Review (What's this?)

it was great to be able to reconnect with my old tapes, my cd's, and yes, my 33 1/3's and 45's only disappointment, when I needed Cambridge assistance when I was installing, they were rude and didn't help much ... that's Cambridge customer service, not Crutchfield's Crutchfield's customer service has always been nothing but helpful and attentive



Cambridge Audio Topaz Receiver

Bill from Pennsylvania on 11/5/2015

Crutchfield Customer Review (What's this?)

I replaced a 20+ year old Marantz receiver with this unit after it finally failed. This is a good solid "classic" stereo receiver in terms of functionality - phono connections and pre-amp, AM/FM tuner (no internet radio) and 4 analog and 2 or 3 digital connections (I haven't used any of these). It has a good Wolfson DAC and produces accurate rendering with good imaging on a variety of music. It has a decent (although not outstanding) FM tuner in terms of sensitivity. It even comes with a little plastic AM antenna which I hooked up to get traffic reports when needed. It has ample power for the application and speakers I have connected. The fit and finish are also good and it seems solid. I decided on this unit as opposed to the Cambridge Audio Integrated amp and a separate tuner just on the basis of cost and to date it has met all of my needs. I have it hooked up to in wall speakers which came with the house so that is the limiting factor on my stereo system - this unit could be spectacular (or maybe not) with great speakers and I would not know. Setup and connections were easy.

Pros: A very solid stereo receiver which produces good quality music at a moderate price.

Cons: About two thirds of the remote is devoted to other Cambridge Audio devices (CD player?) and are therefore not usable. No paper user manual is included but the manual available as a download is fine. The main power on/off switch is in the rear of the device which is not readily accessible if the receiver is put into a cabinet (as mine is).


Hands-on research

Product Research


Stereo Amplifier: The Cambridge Audio SR20 stereo receiver employs a fully-discrete, high-power, class A/B amplifier rated at 100 watts RMS x 2-channels. The amplifier can handle impedances between 4 and 8 ohms.

Toroidal Transformer: The Cambridge Audio SR20 stereo receiver employs a powerful toroidal transformer. Benefits of a toroidal transformer include:

  • High quality power output to the amplification circuits, with no clipping, transformer noise, buzz or hum, to provide a consistent signal.
  • High power output, to allow large and demanding speakers to be driven at high volumes with sensational bass performance.
  • Large power reserves, to allow the transformer to deliver high peaks of volume when required.
  • Fully shielded against internal and external electrical interference, to maintain quality of power and signal.

Acoustically Damped Metal Chassis: Electronics (and therefore sound quality) are particularly susceptible to vibration; that's why Cambridge Audio used a low resonance, acoustically-dampened metal chassis to eliminate as much vibration as possible, ensuring that the most sound quality is extracted from every source.

Wolfson DAC: The Cambridge Audio SR20 stereo receiver utilizes a 24-bit/192kHz Wolfson DAC (digital-to-analog converter) for exceptional sound quality.

Inputs: The Cambridge Audio SR20 stereo receiver features a variety of connectivity options with analog, digital, and phono inputs.

  • Digital Inputs: The SR20 offers digital connectivity with two optical (toslink) digital inputs and one coaxial (RCA) input. The digital inputs will accept 2ch PCM audio. The optical input supports up to 96kHz, while the coaxial input supports up to 192kHz.
  • Analog Inputs: The stereo receiver includes a total of five analog audio inputs; 3 stereo RCA inputs, Phono input, and a front-panel 3.5mm input.
  • Phono Input: The SR20 features a Phono input for connection of your turntable. Turntables fitted with phono cartridges of either the Moving Magnet (MM) or high output Moving Coil (MC) type (between 2-6mV output and 30-50k load impedance) can be used.
  • Front-Panel Aux Input: The Cambridge Audio SR20 stereo receiver features a front-panel 3.5mm auxiliary input for temporary connection of a portable digital audio player. Connecting an audio device to the front-panel 3.5mm auxiliary input will override the unit's rear-panel RCA auxiliary input.

AM/FM Tuner (w/ RDS): The Cambridge Audio SR20 stereo receiver features a built-in AM/FM with manual, seek, and preset tuning. You can store up to 30 AM/FM station presets (15 each). The built-in AM/FM tuner features RDS for station name display on FM stations that support this function. For low quality stereo FM signals, selecting the Mono mode can reduce the noise and improve reception. You can also select between US or European tuning.

Outputs: The Cambridge Audio SR20 stereo receiver offers A-B speaker outputs, a mono-RCA subwoofer output, and front-panel headphone jack.

  • A-B Speaker Outputs: The Cambridge Audio SR20 is equipped with A & B speaker terminals to connect two pair of loudspeakers or bi-wire a single pair of loudspeakers. You can select which speaker outputs are heard - A speaker only, B speaker only, A+B speaker, or Off. The amplifier can support a 4-ohm load when driving only one pair of speakers. The amplifier can support an 8-ohm load when driving two pair of speakers.
  • Subwoofer Output: A single rear-panel mono-RCA subwoofer output is used to connect a powered subwoofer for a 2.1ch speaker system. The sub out has a fixed 200Hz low pass filter.
  • Record Output: There is a stereo Record Output for connecting a CD recorder.
  • Headphone Jack: The Cambridge Audio SR20 stereo receiver is equipped with a front-panel 1/4" headphone socket for connection of a set of headphones. The amplifier's speaker outputs are muted when headphones are connected. Headphones with an impedance of between 32 and 600 ohms are recommended.

Controls: The Cambridge Audio SR20 features front-panel controls and comes supplied with an IR remote control for wireless operation of the stereo receiver. The included remote control will also operate playback function of the Cambridge Audio CD10 CD player (779CD10, sold separately).

  • Volume: The Cambridge Audio SR20 features a front-panel rotary dial to increase or decrease the level (-80 to 0) of the sound from the speakers outputs and headphone output of the unit. You can also use the included remote control to adjust the volume level.
  • Bass & Treble: The Cambridge Audio SR20 offers Bass (100Hz) and Treble (20kHz) controls which are adjustable from -10 to +10dB.
  • Balance: The unit also allows you to balance the unit's speaker outputs left-to-right (+/-10).

Front-Panel LCD: The Cambridge Audio SR20 stereo receiver features a front-panel LCD for the display of information, such as the selected input source, station identification, volume, and tone/balance level.

It has audio inputs which allow for any line equipment like CD/BD/DVD with inputs. Can't specifically say whether or not an equalizer would work. What I can say is this is the best, most powerful and cleanest amplifier I have ever owned. Awesome power and sound! Would buy again in a second. [ BILL  Aug 22, 2018 ]
There are no inputs specifically for an equalizer. It has a 3-band built in. [ CHRISTOPHER T  Aug 22, 2018 ]
Yes you can with digital audio audio inputs or cra cables [ carl  Jan 17, 2018 ]
Sure, assuming you use good rated cables and connections like banana plugs etc.,,, [ Stephen  Jan 16, 2018 ]
Yes, I have my DVD hooked up so we can what movies and/ or listen to music. It's pretty basic. Hook up the DVD video to the TV and the audio to the receiver. When you want to what a movie, turn every thing on and choose video 1 on the TV input. Hope this helps. This is a great unit! [ THEODORE  Jan 16, 2018 ]
Absolutely. I currently run my Panasonic and Blu-ray player through this recievers. I much prefer using to large crate speakers. Also the recievers with all the fancy Sound stuff. Has a delay from the pic to Sound. This Cambridge is perfect [ JAMES  Jan 16, 2018 ]
Well - the answer is that depends - if your TV or DVD have RCA (red and white jacks) outs, then you could hook them up to one of the line inputs on this receiver. If they have an optical out it might be possible to use the optical in on this receiver (I say possible depending on the format used by the optical out on the TV). But if all you have is HDMI on your TV or DVD, this receiver has no input for that. I've asked questions at the Cambridge Audio website on this very piece of equipment and they were quick to answer and very informative. [ Ed  Jan 15, 2018 ]
Thats what I do. It isn't a surround sound system though. It's just a simple excellent sounding stereo amp. [ STEVEN B  Jan 15, 2018 ]
Yes, but if you have an older TV you made need an adaptor depending on the types of audio out options you have. I run my TV, DVD, phono & Echo with no problems. Still has a few more input option available. [ James  Jan 15, 2018 ]
Yes, provided all speakers are 8 ohms or greater. [ Jon  Oct 28, 2017 ]
I have not tried it yet, but according to the manual, the answer is yes. "The use of A and B speakers affords you an easy and inexpensive way to create a simple multi-room system. NOTE:When using two pairs of speakers, use speakers with a nominal impedance of 8 ohms." On the next page it says "The Speaker A/B button toggles between two sets of loudspeaker terminals. The options are speaker A only, speaker B only, speaker A and B together, and both sets of speakers off." [ Richard  Oct 27, 2017 ]
Yes. The speaker select button allows "A", "B", "A+B" or "off" [ Charley  Oct 27, 2017 ]
Yes. From the manual (support section of the Cambridge Audio website, search on 'SR20') "Either A or B, or both A and B may be selected for use. Note: When using two pairs of speakers, use speakers with a nominal impedance of 8 ohms each." [ Ed  Oct 27, 2017 ]
According to there manual, the answer is yes [ DAVID  Oct 27, 2017 ]
According to the manual the cut-off is at 200 Hz [ Jon  Oct 28, 2017 ]
If you click on details you will see that the sub out has a fixed 200Hz low pass filter. [ Jon  Jul 11, 2017 ]
As far as I know there is no cross over. [ Joseph Graves  Jul 07, 2017 ]
It is full range and doesn't have a gain either. However, my sub has those. I still like the receiver a lot. Sounds super good. I would recommend. [ STEVEN B  Jul 07, 2017 ]
Good Lord! I don't even know what the question means. Advise the customer to talk one of your appropriate technicians. I have, and they are very patient and knowledgeable. [ JEROME M  Jul 07, 2017 ]
I'm afraid that information is not provided for either of these Cambridge models. The only details on the headphone output state "The amplifier's speaker outputs are muted when headphones are connected; and headphones with an impedance of between 32 and 600 ohms are recommended" You may want to try contacting Cambridge's support directly for more details--you can reach them at 800-663-9352.

Yes by putting it in the standby mode [blue light] the remote will function perfectly! [ CRAIG H  Feb 06, 2017 ]
Yes. With the power switch on the back turned on the unit is in a low power stand by mode when not being used. The unit even goes into standby mode when not being used for 30 minutes. Handy when you fall asleep [ THEODORE  Feb 04, 2017 ]
IF the standby button on back is on, than yes you can turn the receiver on with the remote [ DAVID  Feb 04, 2017 ]
Yes, you can turn it on and off using just the remote. It will also automatically "power off" if you don't play anything for a while. [ Chris  Feb 04, 2017 ]
Yes [ bob  Feb 03, 2017 ]
Leave it on stand by at all times. Use the remote to switch to power up. [ Joseph Graves  Feb 03, 2017 ]
Yes. Just press the power button on the remote. [ JAMES  Feb 03, 2017 ]
You can send an email to Cambridge directly, but I believe the answer is no. The power switch on the back is a 'master' switch, and the one in front is a standby, and so is the one on the remote. So, you turn the power on in the back and leave it on at all times. It consumes almost no power (1/2 a watt) in standby. [ Ed  Feb 03, 2017 ]
Yes the power is always on in back then you power on and off with remote or button on front. It never powers completely off it goes into standby by [ dennis  Feb 03, 2017 ]
You can use the front panel "MP3" jack to play from an iPod/iPad/iPhone. That's what I do. The jack is analog. The only digital inputs to the SR20 are on the back and are Toslink optical and RCA-jack S/P DIF digital audio. I haven't found a convenient way to get Toslink or S/P DiF off of an iDevice. There are cables to get TOSLINK from a Mac that plug into the headphone jack. PCs seem to be all different, so you can go hunting for a digital audio output adapter from whatever PC you have (if it's a PC). [ ALAN  Dec 07, 2015 ]
