Our take on the Russound X75

Today's networked audio players, music streaming services, and remote control apps for smartphones and tablets have radically changed the way we experience music at home. You still need good clean power to drive your speakers, but you probably don't need a traditional receiver with a lot of buttons to push. Maybe all you really need is a smartly automated amp like the Russound X75.

Today's networked audio players, music streaming services, and remote control apps for smartphones and tablets have radically changed the way we experience music at home. You still need good clean power to drive your speakers, but you probably don't need a traditional receiver with a lot of buttons to push. Maybe all you really need is a smartly automated amp like the Russound X75.

Connect one music component as your primary source, and it will activate the amplifier when it sends out an audio signal. The amplifier returns to standby mode when the audio signal ceases. Your secondary audio source takes over automatically when there's no signal coming from the primary source. There's no need to manually switch inputs.

Say you have a network audio player, such as a Sonos ZonePlayer 90 connected to the primary input. Any time you fire up the ZonePlayer, your X75 turns itself on and feeds the music to your speakers. Because the X75 has two sets of speaker outputs, you could be listening in the den, the kitchen or wherever you chose to install your speakers. Because you control the ZonePlayer with a wireless controller or smartphone app, it doesn't matter where you put it. The ZonePlayer and the X75 could be out of sight in a utility closet or cabinet.

You might connect an old-school music source like a CD player to the secondary input, and enjoy it whenever you're not using your ZonePlayer. When a CD stops playing, the X75 will automatically switch to standby mode.

Simple, Reliable, Clean Quality Sound

Ron from Trinity, FL on 1/24/2015

Crutchfield Customer Review (What's this?)

Originally bought one X75 and a receiver/amp. Should have followed Crutchfild advisor and bought three amps. Sent back the receiver/amp and bought two more X75's. Simple to use with wireless DAC from laptop. Have amps chained together powering four pairs of speakers and can add two more sets. I set maximum volume for each zone then control overall volume at laptop or via app on smartphone. The music sources may change but I believe these amps will be putting out good quality sound for another thirty years.

Pros: Easy setup, quality sound and plenty of power. I can change inputs as technology changes but the amps don't have all the bells and whistles to go bad or become outdated. Best solution for multiroom speakers.

Cons: Can take up a lot of space for cooling but I would rather have that fan's to go bad or large expensive copper heat sinks. Wish I would have bought one more.

Drive subwoofer good

Sounds great, setup was a like quirky.

Pros: Sounds great

Cons: Setup was a little quirky

auto input switching

Anonymous from Annapolis, Maryland on 12/22/2014

Crutchfield Customer Review (What's this?)

When my pre-amp is connected to the Line 1 input, the music cuts off during quiet passages, with a relay-sounding snap from the unit, and cuts on with a snap when the music volume goes up. The manual/auto switch on the rear is set to manual. It appears the auto input switching feature cannot be turned off, but only works on input 1. I now run my pre-amp into the Line 2 input and no longer have the problem with auto switching cutting off my music. I will not be using the Line 1 input and suggest Russound review the design and documentation of their input switching feature. Otherwise, it is a fine unit.

Pros: price and performance

Cons: auto input switching design and documentation

Crutchfield Customer Review (What's this?)

Purchased this amp to expand 7.1 Dennon 4000 to 9.1. added benefit of auto source switching enabled adding small speakers for normal TV viewing greatly improving sound

Pros: Price for quality, auto source switching & size

Cons: none

very satisfied

hopper from Scranton PA on 12/15/2014

Crutchfield Customer Review (What's this?)

Using this amp with a Sonos (only had SONOS preamp unit). Powers 4 ceiling mounted infinity speakers over two rooms more than well enough. Also use secondary output signal to powered subwoofer in same setup. Does exactly what I needed it to and for a great price. BTW: Thanks to Crutchfield tech for help setting up entire system. Very satisfied.

Pros: The auto shutoff feature is a great asset for how I use it since the amplifier is remotely located and the system is operated wirelessly.

Cons: Just be aware there are no other bells and whistles with this unit. Volume, balance, A&B speaker switch. Limited outs.

great product for the price

Russound x75

jammin900rr from Roseville, CA on 7/17/2014

Crutchfield Customer Review (What's this?)

Works like a charm. The X75 is running as my outdoor amp off of a Denon AVR-X4000 on Zone 3. Right now there are two Definitive Technology AW-6500s installed under eave, with a single Niles volume selector. I used 12-4 CL2 wiring for the entire setup. Although I've only used the system for a maximum of 4 hours total (speakers should need an additional 16 hours to really loosen up), the sound reproduction is superb. The X75 has more than enough power to fill the backyard (1/4 acre total) with only two speakers. Although I could run 2 pairs, I think it's more than sufficient. The AW-6500 bass reproduction is better than I expected (not requiring an additional outdoor sub). I think the X75 was a perfect match for my needs

Pros: Pricing; ease of installation; auto-detect source; auto-standby

Cons: none

Great Product for the Money

RonD from Estero, FL on 7/1/2014

Crutchfield Customer Review (What's this?)

This amp is perfect for my needs to power a set of indoor and outdoor speakers. Very happy with the power and sound quality. Simple operation. Good price and support from Crutchfield.

Pros: Simple to use, good power and quality.

Cons: None

Great, simple amp

Anonymous from Seattle, WA on 6/30/2014

Crutchfield Customer Review (What's this?)

I bought one of these for two living room music in-ceiling speakers, and it pumps out plenty of volume, with no issues whatsoever. Liked it so much I bought another for the outdoor speakers so that their main volumes could be different and my phone/iPad could be the only source with a common source volume. Cascade inputs are perfect for multiple amps with the sub the last component in line. Flawless and really simple. Auto-off works great, and my wife loves that she doesn't have to go find something to turn on, it just works. Heat doesn't seem to be an issue yet either, and I have these both high up in a closet. I would definitely recommend this amp.



zone 2 amp

Andrey from Naperville, IL on 6/19/2014

Crutchfield Customer Review (What's this?)

Works as described. Connected it to zone2 on my marantz sr6008. Enough power for my neighbours to join the party :-)

Pros: Simple. Plug'n play. Small. Turns off when main unit is off.

Cons: Hot when it works.

Solid product

HorenK from Dove Canyon,CA on 6/13/2014

Crutchfield Customer Review (What's this?)

It is a very solid amplifier for the price range. It is used to provide music to 3rd room.

Pros: Well sounding amplifier.

Cons: In auto mode pretty sensible, turns off prematurely.

Rusts sound

Gjbowman from Lehighton, Pa on 4/21/2014

Crutchfield Customer Review (What's this?)

Good quality sound, good price for quality, watch heat radiated from unit, keep air flow going.

Excellent Product

EarleW from Passaic, NJ on 4/10/2014

Crutchfield Customer Review (What's this?)

Excellent product, clean sound and enough power for my purposes, felt good about buying from Crutchfield because they stand by what they sell, will be making more purchase from Crutchfield.

Pros: Good Crutchfield service.

Cons: None

My Amp is a blast!

Federico S from Chamisal NM on 3/13/2014

Crutchfield Customer Review (What's this?)

My amp is a b;art Much more than I expected for the price. The separation and bridge option is very nice. I use it in my living room. The system I have didn't have the boost I wanted so this inexpensive addition moves my speakers quite well. It also provided plenty of bass that I did not expect. So rock on is definitely in my living room future.I'm used to really loud music Bigger amps and speaker so now I have it in my home.

Pros: Small, thin line, not complicated, and does not get to hot. Price is good.

Cons: Haven't found any yet.

Does the job nicely!

TheRock from NJ on 2/22/2014

Crutchfield Customer Review (What's this?)

Bought two of these to output from TV and drive a pair of speakers/sub to create 2.1 systems. It works great. Turned off TV speakers and let this amp do the work. Unit will power up and go back to standby based on signal.

Pros: Just enough power. Auto on/off works great.

Cons: Nice if it had optical audio inputs and subwoofer pre-out if your application required it.

Billy from Woodbridge, VA on 8/1/2013

Crutchfield Customer Review (What's this?)

Works well so far. I used this to add my outdoor and basement speakers onto my receiver. Now I can have a party with music in all rooms.

Pros: Works well so far.

Cons: None so far (have had for about 2 weeks)

Just what I needed!

Denise from Washington on 7/27/2013

Cons: none yet!

Great Amp

Ratskywalker from Maitland, FL on 7/21/2013

Crutchfield Customer Review (What's this?)

Great powe and clean sound. Using to power two Difinitive technology outdoor speakers and they rock my huge backyard with only one pair of speakers.

Pros: Power. Clarity

Cons: None

Simple is Easy

Gridley from Asheville, NC on 6/22/2013

Crutchfield Customer Review (What's this?)

Very compact unit. Not too many bells and whistles, so it's very easy to hook up and use. I have mine hooked up to a flat screen TV with two sets of Bose speakers - one compact, one mid-size - and the sound reproduction, even at quarter volume, is great. I especially like the option to use one of two audio channels - or both together.

Pros: Multiple outputs, ease of use and installation

Cons: A slight hum when operating.

Great Addition

Don K from Ohio on 6/18/2013

Crutchfield Customer Review (What's this?)

The Russound X75 is a great addition to my audio setup. I am using a Denon AVR-2113 which offers both a line-out and "second zone." Prior to the Russound purchase, I was using the AVR to power additional sattelite speakers using the second zone with limited success. The sound was somewhat weak while pushing the limits of the AVR. With the addition of the Russound X75 using the line-out and a Russound SS-4.2 speaker selector, I am able to push sound to three sets of speakers on the outdoor deck and another set of speakers in an upstairs bedroom. The sound level and quality is clear, crisp, full and more than I anticipated. I have yet to increase the volume past 50% fearing my neighbors will "enjoy" a little too much of my music. Set up was very easy. The component itself is built solid with simple design. My configuration leaves me the option to add yet more speakers (with the addition of another speaker selector.) Listeners have commented that it almost sounds better outside than inside!

Pros: Set up is simple. The component itself is well made with great design and functionality.

Cons: None as of yet.

Works great

Mike from Greenville NC on 6/9/2013

Crutchfield Customer Review (What's this?)

Works just like the sales rep at crutchfield said it would, as usual they sold me what I needed. Thanks guys for the great product and advice.

Pros: Simple, it works.

Cons: None

Perfect for powering second & third zones of speakers

Mike V. from San Antonio, TX on 5/30/2013

Crutchfield Customer Review (What's this?)

Very happy with this power amp. I use it to power my patio speakers as well as some in my game room. I feed it with a Sony A/V reciever and it works great. I love the ability to select either zone or both, an the separate volume control.

Pros: Easy to use, easy to set-up.

Cons: I did have to return my first unit for a replacement because the speaker buttons didn't work right. Crutchfield made this easy and the new unit worked as it was supposed to. Otherwise, no cons.


Bob from Tustin, CA on 5/20/2013

Crutchfield Customer Review (What's this?)

I could not get the remote power on sensing feature to work. I bought the unit because of that feature. I noticed reviews on other sites also mentioned they could not get it to work. I called Crutchfield and they were very nice and emailed me a return label. I was impressed on how easy it was to return. I would definitely buy from Crutchfield again.



Russound X75

Bob from Mineola, NY on 3/5/2013

Crutchfield Customer Review (What's this?)

Excellent amp. I bought this to power a pair of Klipsch KB-15 bookshelf speakers and a pair of Polk Atrium 4's in my basement from my old Carver 6250 Receiver which has a bad amp from shorted speaker wires (moving equipment while on). Now I use the receiver as a tuner and preamp to select multiple sources. The Russound provides plenty of power and can easily be used for multi-room applications. The amp will provide a lot of flexibility as my devices and room configurations change.

Pros: Simple and functional as a multi-room or stand alone amp. Auto on/off when input is detected is a great feature which is perfect for large multiple room/speaker set-ups. Solid controls give a quality feel. Makes an excellent room amp with an iphone (itunes, iheart internet radio, etc) using a mini jack to RCA connector and a pair of speakers.

Cons: Speaker select buttons A/B take some getting used to. After you press both in you must press harder than seems "normal" on the A to reset (release) B and vice/versa. To select both you need to depress A/B simultaneously. Not a big deal, the buttons are very solid, just takes a few times to get used to it. No Bass/Treble controls or headphone jack. The specified ventilation space is also a lot if your equipment is stacked. Overall the pros outweigh the cons, good unit.


Steven Clarkson from Austin, TX on 8/18/2012

Crutchfield Customer Review (What's this?)

My McCormick amp of 18 years just stopped working - I don't have the money or the patience to get it fixed - I ordered the X75 because of the great ratings on many websites. I guess technology has caught up with the extremely heavy, high end amps. Besides the somewhat flimsy speakers connections, this amp is great. Played some Miles Davis from Europe 67 on it last night and I really couldn't see a big difference between my old $1000 amp and this one. Highly recommended and the staff at Crutchfield were great.

Pros: Great price, good sound - I use a high end preamp which may make the difference

Cons: Flimsy speaker connections


beatZ from mifflintown on 7/12/2012

Crutchfield Customer Review (What's this?)

I love it it easy to hook up and functions are beautiful.




Forest from Albuquerque on 6/9/2012

Crutchfield Customer Review (What's this?)

Setting up my sound, I needed a system to power 14 speakers. I was led to these by the Crutchfield adviser, and bought two to hook up in sequence to power 8 speakers. They took some fiddling but they work. A couple things to keep in mind. They do get very hot, and need 8" clearance above for heat dispersal. Also, when installing in sequence, be sure that the "in" line on the first unit is into Line 2, since it will not send a signal from Line 1, to the "Out". It is counterintuitive, but that's why it says "Line 2 out" rather than just "Line out". That also means that if you have a second source into Line 1, the signal won't be transferred down the line, but will only send the one from Line 2. Also to have both "A" and "B" speakers play, you have to push both buttons down simultaneously. For example if the "A" button is pressed, and you press "B", the "A" button pops out and there will be no sound from the "A" speakers.

Pros: works, less expensive than some other options

Cons: odd wiring, gets very hot


Hands-on research

Product Research


Overview: The Russound X75 is a dual source 2-channel power amplifier. The X75 features volume and balance controls, as well as A/B speaker switching on the front panel.

Power Output: The X75 is a Class D amplifier rated at 75 watts per channel into 4 ohms, and 60 watts per channel into 8 ohms. Both amplifier channels can be bridged for a higher power mono output of 160 watts into a single 8 ohm load (The Stereo/Bridge switch on the back panel should be in the Bridge Mono position when bridging.)

Signal Sensing Inputs: The X75 can be turned on manually or automatically by setting a switch on the rear panel. For manual power, the front panel power switch turns the unit on or off. When set to automatic, the unit will power on when music is sensed on either RCA input connector. Once the signal is no longer detected, the unit will automatically shut off. Signal sensing inputs allow the amplifier to easily integrate with multi-room audio systems and home theater components.

Thermal Protection: The amplifier is designed with a special circuitry that protects the unit under a thermal overload condition. Thermal protection mode will only engage when the unit has been run at high volume for extended periods without adequate ventilation and/or when speaker impedances are below the minimum levels. For proper ventilation, it is recommended that the amp have a minimum of 8-1/4" of clearance above, 5-1/8" of clearance behind, and 2-7/16" of clearance in front of the unit.

Short Circuit Protection: In addition to thermal protection, the X75 also has special circuitry to protect the amplifier from short-circuit conditions. This can be caused by a faulty speaker or when speaker wires come in contact with each other. When this condition occurs, the amplifier will shut down until the short circuit is corrected.

Unswitched Outlet: The X75 has a built-in AC outlet on the back panel for powering a device such as a small subwoofer or an audio component. The outlet provides power as long as the X75 is plugged into a live outlet, regardless of whether or not the amplifier is powered on. The outlet is rated at 120 volts and 400 watts.

Q & A

Customer Q&A

5 questions already asked

Hey Ray, Yep. I use this same amp to power 2 separate sets of speakers (1 on my deck & 1 in my dining room). Zone 2. Also have my kitchen on zone 2 but it comes directly out of the receiver. You won't need this if your only running 1 set on zone 2. Should be able to do that directly from the receiver. This amp is if you're powering more than 1 set on zone 2. Hope this helps! Crutchfield has excellent customer service if you have questions. [ BRYAN J  Dec 14, 2014 ]
I think so, but it also depends on your primary receiver/amp. Many multi-zone receivers only have 1 digital zone and then the other zones sometimes only will output analog signals. You'll need to understand how your receiver accepts and outputs digital and analogs signals to be certain. I have speakers under the patio itself that are designated Zone 1 on my Onkyo receiver. I use the Russound amp on my back patio to power additional speakers in the yard as my Zone 2. However, I've only used the yard speakers for music (which has a digital source) not my TV, so I can't tell you if it works for the TV as well. Sorry this doesn't provide a clear answer to your question, but hopefully it gives you some additional pertinent questions to ask. [ John  Dec 11, 2014 ]
I think so if it has a 2 speaker out with an A & B switch. I don't have it any more because I needed more power for my new center channel speaker. I am going high end with McIntosh amp with 300w mono. Sorry if I can't help. [ William  Dec 11, 2014 ]
Yes. However, they will play the same channel or sound at both points. There is no way to have two separate playing areas with different sound. Only one sound (music, TV, etc.) in two places. [ SHARON  Dec 11, 2014 ]
Yes. The product has buttons for either set of speakers, or both. Just be sure to use the right gauge of speaker wire. [ BOBBY D  Dec 11, 2014 ]
I forwarded your question to an Advisor and they responded with the following: Since that amplifier has no way to cut down non-bass frequencies, it should not be used to power a passive subwoofer. We have a few home amps that are specifically designed for use with passive subs, but I would caution the customer to be careful to match the power handling needs of the sub and its impedance to the capabilities of the amps listed- If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Nov 28, 2014 ]  Staff
We have not received any answers from other customers on your question, and have escalated it to an Advisor. We will post the answer as soon as we have it. If you need immediate assistance please contact an Advisor by phone (1-800-324-9695) or online chat. [ Krissy  Nov 26, 2014 ]  Staff
I forwarded your question to an Advisor and they responded with the following: The Russound X75 is a great choice but for 8 speakers you'll want to consider going with 2 of those to power those properly. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  May 17, 2014 ]  Staff
It requires a pre-amp. [ JOHN  Feb 26, 2014 ]
The Russound X75 was a great solution for me , and a lot of bang for the buck Takes the"extra zone/room" signal from my Denon 4310 and powers the other zones...outdoor, and multiple indoor speakers very nicely , sounds great. The volumes of the satellite areas are controlled from multiple Niles impedance matching wall controls....very happy with it david m [ DAVID H  Feb 25, 2014 ]
You can put low level inputs into it, if that's your question. It is only an amplifier, nothing else. We use it to drive a second zone, where the second zone is not amplified coming off the receiver and it works great. [ MICHAEL J  Feb 24, 2014 ]
You will need a preamp. I bought mine to use in conjunction with an iMac, so iTunes, Spotify, etc. can play on my old fashioned, unpowered speakers. So the iMac acts as my preamp. [ STEPHEN  Feb 24, 2014 ]
No. I've never heard the cooling fan at all. I have two of these amps in a rack and they are very quiet. [ Tom  Jan 07, 2014 ]
It has a big heatsink you can see from vents on top of case. It either doesn't have a cooling fan at all, or has a temp. controlled one that only runs under heavy load... Ive never heard a fan running on mine... [ MIKE  Jan 07, 2014 ]
This is a very nice unit. I was not aware it had a cooling fan. Must be quite because I have never heard it and I'm am hyper sensitive to sound. [ SHARON  Jan 06, 2014 ]
I have had no noticeable concerns about a noisy cooling fan. I operate in a cabinet however; so amp is not in room where I listen to the music... [ JAMES J  Jan 06, 2014 ]
James, I bought two of the units and I have not heard the fan at all. Please keep in mind they are in a cabinet, but I am very please with the purchase. Hope that this helps. Clay [ CLAY E  Jan 06, 2014 ]
No. It's very quiet. I do find it's a bit under powered, but all in all a good buy at this price point. [ DAVID  Jan 06, 2014 ]
