Expand your listening horizons with the silver A-S701 Integrated Amplifier from Yamaha. Featuring up to 120W per channel of RMS power at 6 ohms, this amp is equipped with digital inputs for connecting devices like televisions and Blu-ray/DVD players. It offers dual stereo outputs, giving you the ability to power two sets of speakers in different rooms and switch between them, or have them both playing at the same time. To increase the bass output of your sound system, there's also a terminal for connecting a subwoofer.

To reduce distortion and degradation and produce the cleanest possible sound, the A-S701 employs Pure Direct mode and CD Direct mode. Activated via buttons on the front of the unit, these modes cause input signals to bypass unused circuits and cuts off those circuits' power supply. To further ensure quality sound, the amplifier's continuously variable loudness control allows you to balance low and high frequency sounds so you can hear a full tonal range at any volume.

Built to be energy efficient, the amp uses a power management system to switch itself to idle mode when not in use. The A-S701's internal circuitry mirrors itself symmetrically to produce higher signal purity and lower degradation. The chassis is reinforced with a solid center bar to reduce vibration and features a brushed aluminum front panel and knobs. The system comes with a remote control for easy operation.

Engaged by a front panel switch, it matches CD signal levels so each stage produces less noise, resulting in improved signal-to-noise ratio and maintenance of the amp's total gain balance.

The Pure Direct mode causes the music signals to travel the shortest possible circuit route, bypassing the buffer amp and the tone, loudness and balance controls to virtually eliminate any signal degradation for the purest sound quality.

The A-S701 features an analog loudness control on the front panel 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.

This amplifier's left and right channels are organized in a straight, symmetrical layout for limiting distortion and increasing signal purity.

The base of the A-S701's chassis is reinforced with a solid center bar to increase rigidity support and vibration damping, which limits resonance.

You can connect two separate speaker systems in different rooms and switch between them or have them both play at the same time by switching the dial on the front of the unit.

You can connect a turntable with an MM phono cartridge to play vinyl records, allowing you to enjoy records in addition to modern media sources.

This amplifier puts itself into standby mode when it detects that it hasn't been used in approximately 8 hours, minimizing power consumption.

Control your music from afar with the included remote, finished to match the design of the amplifier. The remote comes with batteries and can also be used to control a Yamaha CD player.

With the optional YBA-11 Bluetooth Wireless Adapter, you'll be able to stream music wirelessly from a Bluetooth capable mobile phone or a PC to the network receiver. This amplifier features a DC-out connection on the rear panel to power the adapter.

The rotary encoder makes it quick and easy to select input sources, and the LEDs clearly show which source is selected so you can easily switch between them, even in a dark room.

Q: 1. I am considering buying a Yamaha A-S501 Integrated Amplifier (Silver) from B&H. I have only one question:According to the manual (see page 9 ), in the rear of the equipment there are Audio input/output jacks Used to connect external components, such as a tuner,etc. Are they really audio output jacks? or only input jacks? Can I connect, for instance, a stereo transmitter for headphones?or similar equipments?Carlos

A: Input: 5 x RCA1 x Phono for turntable1 x Optical1 x Coaxial -------------------------------------------------------------------------Output: 2 x RCA4 x Speaker terminal1 x Subwoofer1 x Headphone1 x DC (accessory power)

Q: 2. Does this unit mix down the 2-channel stereo source to all 4 speakers,also thanks for past audio system advice.?

A: Yes it will send stereo to all 4 speakers. Speaker pair A and speaker pair B.

Q: 3. Will this work with 220 volts 50 hz

A: This product is designed to work in a standard power outlet in North America, which is 120V AC 60 Hz only.

Q: 4. Is it possible to use an equalizer with this amp

A: Unfortunately all current Receiver / Amplifiers no longer offer the option to connect a separate Equalizer like the older Receivers sold years ago. The same will apply to this Yamaha A-S801.

Q: 5. I want to connect four 8 ohm speakers to the S-501 and listen to them at the sametime.Am I correct in setting the impedence switch to high? Thanks.

A: No. Set the impedance switch to low. Note the instructions on the back panel.

Q: 6. Can you rack mount this unit?

A: The Yamaha A-5801 does not have rack ears, but can be racked using a shelf, such as the Auray RS-V-1U One-Space Vented Rack Shelf (1 RU), B&H # AURSV1U.

Q: 7. My speakers can be bi-amped. Can I do this with this amp.

A: You could bi-amp two speakers with this amplifier, using the second speaker zone as well as the first.

Q: 8. I have a set of 8 ohm speakers and a set of 6 ohm speakers I want to use at the same time.Do I set the impedence selecter to low or high? Thanks,Joe.

A: Set the impedance switch to "LOW"

Q: 9. Will this amp play all cds in multi-channel stereo.I notice it does not decode like 5.1 receivers.I am looking to upgrade my sound system.Will it sound better then the sony STR-1080 set to (multi channel stereo) with decent speakers?I dont have much experience with sound systems.THANKS,JOE.

A: This is a stereo amplifier (2 channel only) So with two speakers connected it will sound the same or slightly better than the SONY with just two speakers connected. it will not offer you any simulated surround effect as the SONY might.

Q: 10. I have a set of 4ohm speakers and a set of 8 ohm speakers I want to listen to at the same time. Do I connect the 4 ohms to the B speaker terminals and the 8 ohm speakers connected to the A side? The info box on page 5 seems to suggest that. And then set the Impedence selector to LOW ?Thanks!Dick

A: You can use whichever speakers you choose, in either the A or B location. Yes. If one pair, either A or B is 4 ohms, you do select Low.
