Overview: The Yamaha A-S700 Integrated Stereo Amplifier features a
built-in two-channel amplifier with A & B speaker outputs and six analog inputs.
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-S700 features a highly dynamic, powerful
stereo amplifier with low impedance drive capability. The stereo amplifier is
rated at 90 watts x 2-channel at 20-20kHz, in 8-ohms with 0.019% THD.
Bass and Treble: The stereo amplifier features independent bass (20Hz) and
treble (20kHz) controls so you can increase or decrease the low and high frequency
Balance: You can adjust the sound output balance of the left and right
speakers connected to the amplifier.
Loudness: The integrated amplifier 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.
CD Direct Amp: The CD Direct Amp switch is used to obtain the highest sound
quality from compact discs by bypassing the input selector, balance and tone
control circuits. The CD Direct Amp switch routes input signal directly to the
power amplifier from your CD player, regardless of the Input selector setting.
Pure Direct: The Pure Direct switch is used to reproduce the purest
source sound by bypassing balance and tone control circuits.
Speaker Selector: The Speaker Selector switch allows you to select
only A speakers, only B speakers, A+B speakers, or no speakers; so you can
control which speakers are playing.
Impedance Switch: The stereo amplifier features a rear-panel impedance
switch to match impedance level of the speakers connected. There are two levels
to choose from: High or Low.
- High: Select High if you use one set (A or B) of speakers with
the impedance of 6-ohm or higher. If you use two sets (A and B) of speakers
simultaneously, the impedance of each speaker must be 12-ohm or higher. When
making a bi-wire connection, the impedance of the speaker must be 6-ohm or
- Low: Select Low if you use one set (A or B) of speakers with the
impedance of 4-ohm to 6-ohm. If you use two sets (A and B) of speakers
simultaneously, the impedance of each speaker must be 8-ohm to 12-ohm. When
making a bi-wire connection, the impedance of the speaker must be 4-ohm to
Record Out Selector: The integrated stereo amplifier features a record
out selector switch which is independent from the amplifier's input source
selection knob. 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 integrated amplifier comes supplied with an IR
remote control for wireless operation of the unit. The remote control can also
be used to control select Yamaha audio components such as a CD player or AM/FM
tuner. The remote has a range of 20 feet at an angle of 30-degrees left-to-right
of the unit's front-panel IR sensor.
Analog Inputs/Outputs: The Yamaha A-S700 integrated stereo amplifier
is equipped with six analog RCA stereo inputs for connecting an external audio
source such as a CD player, AM/FM tuner, Turntable, and/or cassette deck. There
is also two analog RCA stereo 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. The speaker outputs are color-coded for
easy connection. You can use the A & B speaker outputs to power two pair of
separate speakers or you can bi-wire a single pair of speakers.
Headphone Output: The A-S700 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.
AC Outlets: The integrated stereo amplifier features two switched AC
outlets to power your other audio components.
