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-S300 features a dynamic,
powerful stereo amplifier with low impedance drive capability. The amp is rated
at 60 watts x 2-channels, measured from 20-20kHz into 8-ohms with 0.019% THD
(70 watts x 2-channels, measured from 20-20kHz 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-S300
integrated amplifier features an elegant aluminum front-panel to resist
vibration.
Controls
Bass & Treble: The stereo amplifier features independent
bass (20Hz) & treble (20kHz) 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-S300 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 & 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 & 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.
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).
Auto Power Off: The Auto Power Off feature automatically turns off the
power of the integrated amplifier after a certain amount of time to save energy.
Connections
Analog Inputs/Outputs: The Yamaha A-S300 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.
The unit's Phono input also features
a ground terminal and is designed to connect a turntable with
an MM cartridge. There are also two pair of RCA outputs for recording through the amplifier.
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-S300 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.
iPod Dock: With the optional YDS-12 iPod Dock (item number
022YDS12, sold separately), you can connect your compatible iPod or iPhone
to the A-S300 and control audio playback using the remote control or the iPod
itself. The
YDS-12 is Made for iPod and Works with iPhone compliant and supports the
following iPod model functions (as of 9/11/2012):
