About the Yamaha A-S500
Do you always have to spend a fortune to get high-fidelity sound? Listen to this solidly built integrated amplifier, and you'll agree that the answer is a definite no.
To keep the sound clean, Yamaha keeps the signal path short and well organized inside a sturdy, vibration-resistant housing. A high-current design and high-grade internal components mean you'll have plenty of sonic muscle for dynamic musical peaks. Pure Direct mode lets you bypass the tone, balance, and loudness controls for the purest possible sound.
Because our ears' sensitivity to high and low frequencies is diminished at low volume levels, Yamaha includes a continuously variable loudness control that lets you experience rich, full sound at any volume setting.
The A-S500 offers enough inputs to connect six audio components, including a turntable. Two sets of main speaker outputs let you connect an additional pair of speakers. And the included remote gives you easy control of the amplifier and the other Yamaha audio components in your system.

Product Research
Features
ToP-ART/High Current Amplification: Yamaha uses the ToP-ART (Total Purity Audio Reproduction Technology) design concept, which combines the latest and best technologies, parts, and circuit designs, to maximize sound quality. High Current Amplification uses superior quality components from input to output to achieve high current power with low impedance.
Stereo Amplifier: The Yamaha A-S500 features a dynamic, powerful stereo amplifier with low impedance drive capability. The amp is rated at 85 watts x 2-channels, measured from 20-20 kHz into 8-ohms with 0.019% THD (100 watts x 2-channels, measured from 20-20 kHz into 6-ohms with 0.038% THD).
Dual Heat Sinks: The Yamaha integrated amplifier employs dual aluminum-extruded heat sinks to ensure effective heat dissipation and help achieve crisp, clean sound.
Aluminum Front-Panel: The Yamaha A-S500 integrated amplifier features an elegant aluminum front-panel to resist vibration.
Controls
Bass and Treble: The stereo amplifier features independent bass (20 Hz) and treble (20 kHz) controls so you can increase or decrease the low and high frequency response (+/-10dB).
Balance: You can adjust the output balance of the left and right speakers.
Loudness: The A-S500 features a continuously variable loudness control (0 to -30 dB), so you can retain a full tonal range at any volume level; thus compensating for the human ear's loss of sensitivity to high and low frequency ranges at low volume.
Pure Direct: The Pure Direct switch is used to best reproduce the sound of any source by bypassing bass, treble, loudness, and balance circuits.
Speaker Selector: The Speaker Selector switch allows you to select only A speakers, only B speakers, A and B speakers simultaneously, or no speakers; so you can control which speakers are playing.
Impedance Switch: The 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.
Record Out Selector: The A-S500 features a record output selector switch which is independent of the input source selector; this allows you to record the selected output source while listening to another input source. The unit's volume control does not affect the fixed record level output.
Remote Control: The included IR remote (RAS5) controls this unit and select Yamaha AM/FM tuners, CD players, and iPods (when the optional YDS-12 iPod dock is added).
Connections
Analog Inputs/Outputs: The Yamaha A-S500 integrated stereo amplifier is equipped with six analog stereo (RCA) inputs for connecting external audio sources such as a CD player, AM/FM tuner, Turntable, and/or cassette deck. There are also two pair of RCA outputs for recording through the amplifier.
Note: The unit's Phono input also features a ground terminal and is designed to connect a turntable with an MM cartridge.
Speaker Outputs: The Yamaha stereo 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.
Headphone Output: The A-S500 integrated amplifier is equipped with a front-panel 1/4" headphone output for connecting a pair of headphones (sold separately). The headphone output and speaker outputs will work simultaneously; you will need to rotate the speaker selector switch on the front-panel to the Off position to turn off the sound from your connected speakers.
The Yamaha A-S500 replaces these items
- 85 watts x 2 full-bandwidth-rated

I have had several Yamaha amps over the years. I expected this to be a good amp and It was. The controls are simple and intuitive with no surprises. The sound is great. This was my first purchase from Crutchfield and I absolutely will do business with them again.
