80W x 2Ch Class A Amplification: The Sony ES TA-A1ES integrated stereo amplifier
is rated at 80 watts per channels (20-20kHz) in 8Ω
or 4Ω. The Sony TA-A1ES uses a Class A
amplification circuit hooked up to a tracking power supply that delivers
only as much power as needed, so almost none is wasted as heat. This
innovative amplification technology combines audiophile-pleasing sound with
high efficiency for true high resolution audio performance.
Single Push-Pull Design: The TA-A1ES achieves dynamic output by
using a single push-pull amplifier design. The power amplifying stage, which
determines sound quality, consists of a single pair of transistors,
successfully eliminating the emitter resistance used by conventional
amplifiers to suppress overheating. The transistor output drives the speaker
directly, reproducing sound with greater dynamics and less distortion.
Simplified Power Amp Circuitry:
By including fewer transistors and
eliminating the emitter resistor and coil & capacitor needed in the amp's final
stage circuitry, Sony has reduced the distortion that affects the quality of
your music. This means the amp can deliver a higher power output, so you can
push up the volume and enjoy great, undistorted, High-Resolution Audio.
Digital Sound Enhancement Engine (DSEE): High-Resolution Audio technology
delivers every subtlety and nuance of a song in rich, immersive detail. With
Digital Sound Enhancement Engine (DSEE) technology, you can hear all your music,
even compressed files, in quality closer to the original recording.
Note: Sony's HA-PZ1ES High-Resolution HDD Audio Player (158HAPZ1ES,
sold separately) is the perfect companion to the TA-A1ES integrate amp. Click here for more information on
High Resolution Audio.
FET Input Buffer: The integrated amplifier has been fitted with a FET
input buffer and discrete circuit for the pre-amp. This reduces the effects of
distortion while enhancing the sound quality of High-Resolution Audio. As a
result the integrated amp can produce the sharpness and detail that
high-resolution audio brings to your music with minimal distortion.
Optimum Gain Volume Control w/ Smart BIAS: Sony has combined the
electronic volume with a discrete buffer amp to enhance the overall sound
quality by reducing the gain error experienced by conventional amps. For
long-lasting, high performance, the TA-A1ES intelligently controls the bias by a
volume position to heighten the sound quality. The built-in smart BIAS system
controls the amp's BIAS based on the volume position. In doing so, the amp is
able to utilize a field that experiences good transistor linearity without
generating heat, so the sound quality always remains true.
Frame Beam Base (FBB) Chassis: A frame beam base chassis combines a
conventional frame beam chassis with a transformer base to provide exceptional
rigidity and stabilization. This exceptionally stiff frame helps the amplifier
provide highly accurate sound with little distortion.
Balanced & Unbalanced Inputs: The Sony ES TA-A1ES integrated
amplifier is fitted with both balanced and unbalanced inputs. There is one
balanced stereo XLR input for connecting a high-end CD/SACD or Network player. There are
also four unbalanced stereo RCA inputs for connecting your CD/SACD player,
Network player, external DAC, and more.
Note: There is no phono input on this integrate amp. You will need to
purchase an external
phono preamp (sold separately) in order to connect a turntable to the
Heavy Duty Binding Posts: The Sony TA-A1ES integrated amplifier
features heavy-duty binding posts to connect a single pair of speakers. The
binding post speaker terminals will accept bare wire (up to 10AWG),
pin-connectors, and single banana plugs. The integrated amp supports speakers
between 8Ω to 4Ω.
Note: There is an impedance on the rear-panel of the integrated amp
which allows you to switch between 8Ω
Discrete Headphone Amplifier: To reflect the growing
popularity of premium-quality headphones, this amp includes a specialized
discrete amp with gain optimized to match headphone impedance. The impedance can
be switched among the following settings.
- LOW: from 8Ω to less than 50Ω
- MID: from 50Ω to less than 300Ω
(+10dB against the LOW)
- HI: 300Ω or higher (+16dB against
- OFF: No sound from the headphones.
Remote Control: The Sony ES TA-A1ES comes with an IR remote control
for wireless operation of the integrated amplifier. The remote offers Power
On/Off, Volume Up/Down, Source Input (1-5), Mute, and Display controls.
IR Remote Input: If you connect this integrated amplifier to another
Sony component with an IR repeater output jack, you can operate the amplifier
from the component connected.
Auto Standby: The integrated amplifier switches to standby mode
automatically when no sound has been output for about 10 to 15 minutes.
