About the Yamaha A-S701

David Brown

Potent power, with vanishing distortion levels

It's not hard to find an amplifier that will promise 100 watts per channel of power. But few amps can match that number with such incredibly low distortion as the Yamaha A-S701. This well-built integrated amplifier offers plenty of power to drive bookshelf or tower speakers, including more demanding loads. As you turn up the volume, this amp's anti-resonance construction, symmetrical circuit layout, and high-quality components ensure your music remains clean and clear. By minimizing distortion and interference, your music will sound more listenable with fine details shining through.

By minimizing distortion and interference, your music will sound more listenable with fine details shining through.

Connect your TV and Blu-ray player

The A-S701 has six pairs of analog RCA inputs, including a phono input for connecting a turntable. But music sources aren't the only possibilities: optical and coaxial digital audio inputs let you bring video devices into the fold. Connect a TV or Blu-ray player to these inputs, and enjoy movie sound through your stereo speakers with this amp. It's a cost-effective way to build an excellent two-channel rig in your TV room that offers dynamic sound with a wide stereo image.

Tone controls and direct modes

If you need to make some adjustments as you listen, the A-S701 has front-panel tone controls for bass and treble. There's also a loudness control, for bringing out more detail and depth while listening at low volume. If you prefer a more purist approach to listening, you can bypass these controls with Pure Direct mode, which eliminates signal degradation as your music travels a more direct circuit path. For listening to CDs, engage CD Direct Amplification — it matches the input levels of the source with the amp to further minimize noise introduced at the amplification stage.

"Natural Sound" Concept: Yamaha, with a long history of over 125 years as a musical instrument maker, also has a high reputation for HiFi components. Yamaha's A-S701 integrated amplifier takes advantage of this rich experience and high technological expertise. Based on the concept of "Natural Sound", for reproducing all music as it really sounds, and built with scrupulous care from circuit design to basic sound production, the A-S701 reproduces high sound quality and musically rich sound.

Proprietary Yamaha Technologies: The Yamaha A-S701 integrated amplifier employs proprietary Yamaha technologies for optimum performance and sound reproductions.

  • ToP-ART Design: When processing and transmission of the audio signal is simple and direct there is less chance of it being affected by noise and distortion. Yamaha's amplifier design technology called "ToP-ART" features an I/O (input to output) Direct Symmetrical Design, with left and right channels organized in a straight, symmetrical layout for highest signal purity.
  • ART (Anti-Resonance and Tough): In addition, the ART (Anti-Resonance and Tough) Base bottom chassis and a solid center bar provide high-rigidity support and vibration damping.

High Current Amplifier: The Yamaha A-S701 features a dynamic, high current stereo amplifier with low impedance drive capability. The amp is rated at 100 watts x 2-channels, measured from 20-20 kHz into 8 with 0.019% THD (120 watts x 2-channels, measured from 20-20 kHz into 6 with 0.038% THD).

High Quality Parts: Custom-made power transformer, custom-made block capacitors, two direct signal path speaker relays, one-point grounding system, aluminum-extruded heat sinks and other top-quality parts effortlessly handle demanding audio signal conditions. The quality of each individual part, as well as how they work together, basically determines the sound quality of any component. Yamaha uses only very high quality parts, carefully selected and tested.

CD Direct Amplification + Pure Direct Mode: With a straight connection to the CD input, CD Direct Amplification maximizes the CD source's signal-to-noise ratio. Additionally, engaging the Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp, the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.

Sophisticated Front-Panel Design: With a beautifully simple and unique design inherited directly from Yamaha's HiFi audio components, this amplifier also boast an easy-to-operate button layout. The aluminum front-panel has a richly textured silver hairline finish (the rotary knobs are plastic). The rotary encoder makes it quick and easy to select input sources. The luxury hairline finish material offers a nice tactile feeling. LEDs clearly show which source is selected, so you can easily switch sources even in a dark room.

Controls

Variable Loudness Control: The A-S701 also feature a new analog loudness control on the front-panel that uses electronic volume for higher sound quality, which lets you adjust the loudness effect as desired. Separate from the overall volume, this controls the balance of the low- and high- frequency sounds, providing full tonal range at any volume level; compensating for the natural loss in the human ear of high and low frequencies at soft levels.

Tone Controls: The integrated amplifier features independent bass (20Hz-400Hz band) and treble (3.5kHz-20kHz band) controls so you can increase or decrease the low band and high band frequency response (+/-10dB). The entire low and high bands are increased or decreased (you cannot indicate a specific center frequency for bass & treble). You can also adjust the output balance of the left and right speakers.

Impedance Switch: The integrated amplifier features a rear-panel impedance switch to match the impedance level of the speakers connected. Choose High or Low:

  • High: Select High if using one set (A or B) of speakers with impedance of 6-ohm or higher; when bi-wiring the impedance of the speaker must also be 6-ohms or higher.
  • Low: Select Low if using one set (A or B) of speakers with the impedance of 4-ohm to 6-ohm; if using two sets (A and B) of speakers simultaneously, the impedance of each speaker must be at least 8-ohms; when bi-wiring the impedance of the speaker must also be 4-ohms to 6-ohms.

Simple Remote Control: The clean, simple design of the remote control provides easy-to-understand one-hand operation. The easy-to-use design makes it simple to adjust song volume and order. The remote has a sophisticated looking hairline finish that matches the design of the amplifiers. You can also use the remote to control a Yamaha CD/SACD player.

Auto Power Standby: The amplifier has a power management function that detects when it hasn't been used for a long time (about 8 hours) even though the power is on, and automatically shifts it into standby mode. So even if you forget to turn it off, power consumption will be minimized.

Connections

Gold-Plated Terminals: The Yamaha A-S701 has gold-plated terminals for all of its inputs and outputs. These gold-plated terminals ensure a high quality connection that prevents signal loss.

Analog & Digital Inputs: The Yamaha A-S701 integrated amplifier offers analog & digital inputs for connection of a variety of home audio components.

  • RCA + Phono: The Yamaha integrated amplifier is equipped with six analog stereo (RCA) inputs for connecting external analog audio sources, including a turntable. The Phono input can be used to connect a turntable with an MM phono cartridge to play vinyl records. The unit's Phono input also features a ground terminal.
  • Optical & Coaxial Digital Inputs: The A-S701 is equipped with both optical (toslink) and coaxial (RCA) digital audio inputs. The optical and coaxial inputs will accept 2ch PCM (not Dolby Digital/DTS). The audio stays in the digital domain, giving you pure, pristine dynamic sound for all your entertainment sources, from sports and other programs to movies and concerts.

Recording Outputs: There are also two pair of RCA outputs for recording audio through the amplifier to recording device.

A & B Speaker Terminals: The Yamaha integrated amplifier features binding post terminals for its A & B speaker outputs. You can use the A & B speaker outputs to power two pair of speakers, or bi-wire a single pair of compatible speakers. The terminals are not 5-way binding posts because a plastic collar prevents their use with spade lugs and they are too far apart for dual banana plugs.

Sub Output: A terminal for connecting a subwoofer is provided, allowing you to increase the bass output of your system for a more powerful sound with better overall sound quality

Headphone Output: The A-S701 integrated amplifier is equipped with a front-panel 1/4" headphone output for connecting a pair of headphones (sold separately). When a set of headphones is plugged in, the speaker outputs are automatically muted.

Can I run 3 sets of speakers? I have an Audioflow speaker selector that will switch between 3 sets of speakers.
dale  Nov 21, 2022

A
Greetings Dexter, and thank you for your question. As long as you are using an impedance matching switcher like the AudioFlow and just the A side out or the B side out on the Yamaha (not both), you can use this Yamaha AS-S701 for your 3 pairs of speakers.

Q
CAN A PREAMPLIFIER BE ATTACHED THROUGH AUDIO IN #1 OR AUDIO IN #2, THEREBY CUTTING OFF THE INTERNAL PREAMPLIER , BUT STILL USING THE BASE/TERBLE/VOLUME CONTROLS?
bryan h.  Mar 25, 2022
2 answers
A
You can use line 1 (and probably line 2) to deliver the signal from another source (I used another amp), and the volume and tone controls will work. However, if you are selecting your source I would assume the internal pre-amp is still in use.
ryan  Mar 29, 2022
A
I don't know the answer, but I doubt that connecting in this manner would cut off the internal preamplifier. As long as the Yamaha is getting a signal through Audio #1 or #2, all controls should work just fine, but I don't think it would cut off the built-in preamplifier. It is such a beautiful unit with every conceivable input, I don't know why you would want to even try to cut off the internal pre-amp.

Q
what is the difference between the yamaha AS 701 and the AS801?
bill  Oct 06, 2021
2 answers
A
You can compare both models on the website. The only difference that I can see is that there is no USB port and the 801 is slightly larger in width and depth. Also it is 2 pounds heavier than the 701.
richard r  Oct 07, 2021
A
Essentially the DAC is different. If you plan on connecting computer or phone directly to receiver AS801 is probably better. AS701 is amazing though if you primarily focus on analog sources. You can use AS701 same way but won't decode as many formats and doesn't have USB input for computer. USB can be used with flash drive.

Q
Can this system work with cassette technology ( my husband still loves cassette- playing and recording) is there a record out option so I can try to hook up what ever peice of broken down duel cassette deck to? And if you have a "new" tape deck with duel players , auto reverse - I would be eternally grateful and so would my shrink who has to listen to me
maxi  Jul 15, 2021
5 answers
A
Well Maxi, looks as though your shrink will be able to rest a little bit! There are two pair of RCA outputs that your husband can use for his cassette deck. That being said, he would be a very happy man to have this piece of equipment, the sound it produces is stellar. Good luck!
richard r  Jul 16, 2021
A
Yes it would work with a cassette deck, the amp is amazing , powerful and very very clean sound delivered !
jean dominique  Jul 16, 2021
A
It is not like a tape deck per se. But it does have the ability to record. i'm not sure though how that would actually work though. It is a nice amp.
mark  Jul 16, 2021
A
Line 2 and Line 3 both have Playback/Record connections that will work with a cassette deck.
hal  Jul 16, 2021
A
I would think so as this integrated amplifier has 6 RCA audio inputs and two pairs of RCA recording outputs. You should contact a seller or the manufacturer and ask them to be sure.

A
I can't say to be honest. In the specs it doesn't get into details. Doesn't mention A-B or Class D for example. I can say it is a fine amp. It is running 8 zone speakers effortlessly. Does not overheat. Well made unit. Hey it's a Yamaha.
mark  Jan 04, 2021
A
This is an A B class amp
garrett j  Jan 04, 2021
A
To the best of my knowledge it a class ab. It runs in class a for the first 5 to 10 watts then goes to class b. Because class a amps run hot when using them.And when it goes to class b it runs cooler. but this amp does not run hot.
keith  Jan 03, 2021
A
Class A/B hybrid.
michael c.  Jan 03, 2021

According to Yamaha, the amp circuitry is "based on the [proprietary] ToP-ART (Total Purity Audio Reproduction Technology) Concept."
j michael  Jan 03, 2021
Q
I just purchased the 701 from you all. I have two pairs of speakers coming on Monday. Both are Wharfedale 6 ohm speakers. When playing both A and B simultaneously should I set it at high? I'm NOT Bi-wiring them. Thanks for any help.

A
Don't change anything is what the pros said when I searched for an answer for myself.
james  Oct 08, 2020
A
Yes. You would set it at high. Yamahas manual does a good job of course explaining the settings for speakers.
robert  Oct 08, 2020
A
Connie--I have four 8 ohm speakers connected to mine. So, I'm using both A and B. Since Yamaha says that you can use 4 ohm speakers, I know that you can use 6 ohm safely. But i'm not familiar with a "high" setting. Is it a switch on the back of the amp?
victor  Oct 08, 2020
Q
Can I run 2 sets of 6 ohm speakers on A and B at the same time without bi-wiring them? Do I set it at high or low if I don't bi-wire?
jeffrey  Oct 08, 2020
2 answers
A
Thank you for your response.. Well then, can I run a power amplifier thru one of the input ports on the back and power the speakers through the power amplifier and use the Yamaha A-701 as a pre amp?
jeffrey  Oct 19, 2020
A
Thank you for your question Connie! The Yamaha A-S701 is not able power two sets of 6 ohm speakers at the same time. It can power either set A or set B if the speakers are all 6 ohms. However, this receiver can power two sets of 8 ohms speakers at the same time since it is stable at 4 ohms. If you have any further questions give us a call at 800-324-9695!

Well the dac in the 801 has the sabre dac in it but i dont think it is worth the extra cost. if you dont like the dac in the 701 you can always go with the stand alone dac. But i think the dac in the 701 sounds really good.
keith  May 23, 2020
A
I cant really answer that. I use the Yamaha CD player for my Ipod. I did use the amplifier prior to my purchasing the CD player and the CD player does have a better DAC than the amp. I dont know what the 801's capability is vs 701. Sorry.

This amp permits connection of two pairs of speakers (A & B). You can select to play A set only, play B set only, or play both A & B together.
ryan  Apr 25, 2020
A
Yes. I have Magnapans and Klipsch hooked up and run them simultaneously on A & B setting. Magnapans are 5 ohm and Klipsch are 8 ohm. If 5he impedence is different, make sure you have the lower num ered one on speaker B. I have run 5hem simultaneously for hrs and at about 40% volume, which is fairly loud. I am in it for fidelity not necessarily loud volume. Even at 50% volume, music is clear and precise. Great amplifier for under $1000. To match numbers on another amp, you will be looking at $1500 to $2000. You wont be disappointed .

Q
Will this unit works in India as our operating voltage is 220v 50 hz ?
surapaneni  Aug 23, 2015
3 answers
A
According to the operating manual, "Connect the supplied Power Cable to "AC IN" after all other connections are complete". Remember, this is the AMERICAN manual, and may not apply to India. This manual contains some information for North America, China and Australia, but I see NOTHING for India. My suggestion to you is to contact Yamaha's distributor in India, or see if you can locate this unt in an electronics store where you can look at it.. They can give you a definitive answer. Good Luck!!

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your equalizer. They will be able to pull up this amp and see if it will work. If it does not, then they will also be able to discuss other options with you.

Q
Can you hook up a Streamer to this amp?
robert  Jan 24, 2024
1 answer
A
Greetings Robert. Thank you for your question. Absolutely. Most streamers and all that we carry will have a built in DAC. Then run RCA out to the A S701. If you find a streamer that does not have a DAC, but optical or Coax digital out, the A S701 has those type of inputs as well.

Q
Would I have better results keeping my Fluance RT85 connected to the phono input on the AS701, or would I be better off using the Cambridge Audio Alva Solo? Are they comparable or is one the clear winner?

i think based on the reviews of the cambridge preamp go thru the preamp and use high quality inter connect cables but maybe also try the turntable direct to the a-s701 good luck kirk h.

Good question. I think just like separate amp and preamp, a separate phono preamp would be better. Just don't know how much better. You will ultimately have to be the judge of that. I think it would be worth a try if you could return the phono preamp. You could try it in your home on your equipment. Crutchfield is really great when it comes to returning things. It is part of what makes them so good at what they do.

There are several inputs. If you have an adaptor cable that has RCA's at the end I think it would work.

Yes, via a cable with a mini jack on one end and rca plugs on the other.

how will this do powering 2 cerwin vega at-15s, 4 ohms? ive heard that it's not a good idea to fiddle with the impedence switch on the back of amps and to just leave it on 8 and that this Yamaha 701 has plenty of power to drive them

This probably the answer you were looking for . However I've had a pair of Snell E iii for a long time . Wonderful speakers . Got tired of constantly rehabbing vintage gear to drive them. Worry free deal now. Current reliability., classic sound .

I use this amp with my vs-120 speakers 4ohms. It works great. As far as the impedence switch, I've tried both ways and it is good either way. My speakers are a bit away from the amp (they are in my shop) and have no issue with good wire. Tons of full sound. I tried going cheaper and hated it. This amp is a bargain for what it does. Pull the trigger you won't be sorry.

Q
Does the subwoofer out signal bypass the tone controls? Like Pure Direct mode?
greg  Aug 20, 2021
2 answers
A
I believe it does not. I do not have a subwoofer to hook up yet. I believe when you adjust your tone controls, you are also controlling the subwoofer. If you use the Pure Direct, like I like to every so often just to hear what was recorded on my vinyl, then you know longer have control what comes out of your subwoofer. The subwoofer connection is just an extension of your speaker connections. ( A terminal for connecting a subwoofer is provided, allowing you to increase the bass output of your system for a more powerful sound with better overall sound quality. ( Found on a website ) )
kevin w.  Aug 21, 2021

I didn't do much experimenting. With my particular subwoofer, using the sub out was much too loud, even though I usually have the bass turned down some (most movies and TV have way too much bass). I went back to letting the crossover handle it (my speakers have a built-in powered subwoofer that can be fed directly or via the crossover). So maybe the tone controls are being bypassed, but I'm not sure. I just know that I didn't like the result of using sub out.

impedance selector low and high ? can someone explain this to me ? i have speakers rated from 4-8 ohms,so what is better to use ?
filipv  Nov 19, 2020
2 answers
A
If your speakers are 4 ohms or above, use the low switch. If they're 6 ohms or above, use the high switch. If you're running two pairs of speakers at the same time, they both have to be 8 ohms or above and the switch should be set to low.
hal  Nov 19, 2020

Yes Filip i leave mine set on 8 ohm all the time.But it can be confusing. I hope that helps...

No, when powering two sets of speakers simultaneously, the impedance of each set of speaker must be AT LEAST 8-ohms.

Q
Does use of analog inputs with external DAC baypass Yamaha's internal DAC (there is no another A-D conversion). And if answer is positive, which analog input to use?
naumhn  Sep 30, 2018

A
Yes - External DAC to Analog input will bypass the internal DAC. Which input to use will depend on what kind of source you are trying to connect.

Q
Can I connect Polk Audio RTIA7 Tower speakers to this amp?
sandy  Dec 15, 2016
8 answers
A
Yes, the AS-701 is rated at 100 w per channel, the RTiA7 speaker is rated to take up to 300 watts. Physically the connections are compatible as well but make sure to get high grade cable and match the connectors (banana plugs) on each end, my Polks have banana receptacles and the AS-701 I own has them as well. Be careful though if you are expecting to use the speakers at full rated power of 300 watts as the amplifier will probably begin to clip at the the top of its output range. Also, I've noted that my Polks aren't quite as efficient at low power as other speakers I own but they sound great.

Yes you can add those speakers to the amp. May I add that A-S701 is quite a piece of equipment, the first that hit me is the clarity. Excellent choice

Sandy, I am not familiar with the Polk RTIA7's but I have NHT Towers connected to mine. I can tell you that initially after receiving this amp and having replaced a Denon with identical power I was a bit underwhelmed. Its now been two years later and I have really grown to LOVE this Yamaha. At first I felt its bass response was a tad lacking compared to the Denon but I can honestly day that was a mistake. I would describe this amp as precise. I cant imagine why these Polks would not work well although I do not know their OHM rating. As a bass and guitar teacher I consider myself extremely picky as to the performance of my stereo gear. I have many friends who are serious audiophiles who have EXTREMELY expensive high end gear and they all have been blown away by this amp. I find it to be exactly what I was after in an two channel audio only amp. I am completely satisfied with the performance and quality of this amp. I can only imagine that your Polk towers will sound great with the Yamaha. The one thing about the Yamaha that took some getting used to compared to the Denon was the way the volume control was calibrated. The Denon displayed most of its power between the first half of the dial. Once past halfway not much changed. The Yamaha is more conventional as I use it past the halfway point on occasion and it keeps getting louder and stays remarkably clean doing it. I use this amp quite often , I am partial to two channel amps and I would definitely by it again if anything happened to it. Extremely pleased. Good luck.
michael  Dec 16, 2016

Absolutely. 8 ohm speaker rated for 300 watts. Amp is rated for 100 watts into 8 ohms. You won't have the headroom of a bigger amp. Based on the sensitivity of the speaker, 89db, you'll hit just over 107db at full volume which is typically enough for most people.
william  Dec 16, 2016
A
absolutely. This amp takes either banana connections or bare speaker wire, the other end of the speaker cable would, of course, have whatever connectors are compatible with the Polks.
wade  Dec 16, 2016

If you are asking if this will have enough power to move the Polk RTiA7s.... I would say absolutely yes. It is a very powerful amp with little distortion. This amp also has A/B channels which will allow you to bi-amp those speakers if you desire. I my opinion... this amp is in a 'better class' than your speakers. And pairing it up with those speakers might be doing the amp an injustice. However, dollar for dollar, I can not imagine any other amp that can make the Polks sound the best they can sound.

I have the 701 running my Klipsch RP8000. I think this is a happy marriage. I don't think the treble is bright. I have the base turned up just a little bit. Maybe 1 o'clock on the dial. Great depth, detail and musical. Very happy with this system. Hope this helps.
gary  Dec 19, 2021

I'm am not running Klipsh but I am running NHT towers. When I first received this amp I somewhat felt that it didn't have the warmth my Denon had. Now that I have owned it for over a year I have gotten to appreciate just how clean this amp is. Wish I could help you with the specific speakers but this maybe of some use. I am pleased with the amp though. Extremely clean.
michael  Oct 24, 2016

I have this amp paired with Martin Logan 60XT floor-standing speakers. I think the 60XTs are a bit nicer than the amp...but the sound quality sounds great. I particularly like the amp...i spent a lot of time researching integrated amplifiers and finally settled on the A-S701. I much recommend this amp.
