Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
- On/Off switch with a LED that blinks when
first turned on and goes off to indicate that unit is ready. Note that when this model is
used with the TA-9000ES preamplifier the LED lights in red to indicate standby
- LED indicators light to show which mode has
been selected and blink if you select a mode that can't be used. There are LEDs to
indicate BTL 2 channel, BTL 2+1 channel, 2 channel, 3 channel, 4 channel, 5 channel,
warm up, BTL extra 2 channel or extra 2 channel modes.
- Operation Control: A rotary knob allows you
- 2 ch: Selects Front left and right channel
- 3 ch: Selects Front left and right and Center
- 4 ch: Selects Front left and right and Rear
left and right channel outputs; when in BTL (Bridged mode) this position is BTL 2ch which
will output signals input to the front or rear inputs to the Front left and right BTL
- 5 ch: Selects Front left and right, Center
and Rear left and right channel outputs; when in BTL (Bridged mode) this position is BTL
2+1 ch which will output signals inputed to the front or rear inputs to the Front left and
right BTL speaker connections and will output signals input to the center input to the
center speaker jacks.
- Extra 2 ch: Any signal input to the Extra 2
channel input jacks are output from the front left and right speakers; when in BTL
(Bridged mode) this position is BTL Extra 2ch which will output signals input to the Extra
2 ch inputs to the Front left and right BTL speaker connections.
- Warm up: This position is normally used
instead of turning the power off to keep the circuitry warm when the unit is not being
used for better sound quality when the unit is first turned on.
- S-Link (Control A-1) inputs: Two mono
minijack inputs; when used with the 156TAE9KES this model will automatically go into
standby mode when the preamplifier is switched to standby and turn on when the
preamplifier is turned on.
- Gold plated RCA input jacks for right and
left rear; center; fight and left front; and right and left extra 2 channel
- Operation switch: Can select normal for 5
channel mode or BTL for bridged mode
- Impedance switch: Can select one position for
4 ohm minimum in normal use (8 ohm minimum in bridged mode) and another position for 8 ohm
minimum in normal use (16 ohm minimum in bridged mode)
- Binding posts for right and left front
speakers; right and left rear speakers and center speaker. Note that they are not 5
way posts because a plastic collar prevents the use of spade lugs. In BTL
(bridged) mode the Front Right and Rear Right positive speaker terminals are used to
connect the right speaker and the Front Left and Rear Left positive speaker terminals are
used to connect the left speaker
Parallel Push/Pull output with 4 transistors per channel
Frame and Beam construction: Maximizes
chassis rigidity to reduce unwanted vibration
sf FinTM heat sink reduces
resonance and vibration
Inner Monocoque chassis construction separates mounted
circuits from outer chassis
Direct Ground DriveTM Power Supply
Extra 2 CH Input: Allows you to input a
stereo preamplifier and have its output amplified by the left and right channel only.
Two channel mode: 120 watts per channel
minimum RMS with no more than .03% THD at 8 ohms from 250 milliwatts to rated output
BTL Mode: (8 ohms 1kHz, THD .013%): Front
200 Watts + 200 Watts; Center 120 Watts
Speaker Nominal Impedance: Front, Rear and
Center - 4 to 16 ohms in Normal mode; 8 to 16 ohms in BTL (bridged) mode
Input sensitivity: 1V +/- 1 dB
Frequency response: 20-20k +/- .2dB; 10-100
kHz (+0/-3dB) at 1 watt
Power consumption: 4.5A
Note: US warranty cards states 3 years;
actual Sony ES parts and labor warranty is 5 years.
