FRONT PANEL CONTROLS
Master Power Switch / Indicator LED
1.
Front panel pushbutton power switch turns the amplifier on and off. When the
switch is on and the indicator LED is red, the amplifier is in standby mode. The
remote turn on switch (located on the rear) is either in the “trigger” or “auto”
position. When the LED is blue, the amplifier is fully active. The master power
switch will turn off the amplifier no matter which power mode has been selected.

Zone Status Indicators
Each pair of channels or zones has a bi-color LED to indicate its operational
status. These indicators provide quick and easy troubleshooting of the system. If the
circuitry determines that a channel must be shut down due to excessive heat or low
impedance (a short), only the channels that are affected will be turned off causing
the zone LED to turn red. The remaining zones will continue to operate and maintain
a blue LED status. Once the condition has been corrected for the zone in question,
the status LED will return to blue.
Note: When the power LED is red and the zone status LEDS are not lit (off) indicates
the unit is in stand by mode.

BUS Line Inputs / Outputs
3.
The AMP1200VS has two common or BUS inputs that receives audio signals
from standard line-level audio sources and sends them to any or all channels. The
BUS line outputs are direct feed-through to allow the BUS inputs to be fed to other
amplifiers. Be sure to use high quality RCA cables that feature low impedance,
shielding and high quality connectors.
4.
Remote Turn-On Switch
This switch selects the turn-on stimuli that will put the amplifier in ready mode.
“Trigger” setting relies on 3-30V AC/DC voltage going into the trigger input to
activate the amplifier. “Auto” setting senses a signal on the RCA line-level inputs
and automatically puts the amp in ready mode. “On” setting puts the amp
constantly in ready mode so that it can be controlled by the master power switch
on the front panel. In “Auto” mode, the amplifier will take approsimately 15
minutes to return from ready to standby mode.
5.
Trigger Input / Output
The trigger input is a handy feature when connecting the amplifier to an
automated audio system. The 3.5mm miniplug jack will accept a 3-30V AC/DC
output from another device, or from a separate power supply. When the trigger
input is energized, the amp turns from standby to ON mode. When using the
AMP1200VS with a receiver without a trigger output, the voltage can come from a
12V wall wart (3.5mm tip-positive connector) plugged into the receiver’s switched
outlet and the trigger input. The AMP1200VS can also provide an output trigger
voltage (12DC @500mA max.)
When the amplifier turns off (standby mode), the voltage will drop to zero.
6.
Channel Gain Control
Each channel has its own independent level adjustment. This allows the output
level of each speaker to be perfectly matched to its area. It can also be used to
limit the maximum audio level in a certain area.
Bridging Switch
7.
By simply flipping a single switch, two channels can be combined to increase the
total power output. This is helpful when extra power is needed in certain areas.
Note: The minimum impedance for bridged channels is 8 ohms. Also, please
observe the proper speaker wiring when bridging channels. Input selection and
volume settings for bridged channels will be controlled by the left channel. “BR” is
bridged mode and “ST” is non-bridged or stereo mode.
to turn on and off other devices in the audio system.

Input Selection Switch
Each channel is capable of delivering the source from many inputs. The three main
inputs are BUS 1, BUS 2 and LINE IN. The selection for these inputs is done via the
Input Selection switch associated with each channel. Select the desired source input.
Set the Input Selection switch to BUS 1 (will play source connected to the BUS 1
input), BUS 2 (will play source connected to the BUS 2 input) or LINE IN (will play
source connected to that channel’s LINE IN).
Speaker Output Terminals
9.
The AMP1200VS uses high quality Phoenix style connectors for the speaker
connections. Use 14-18 gauge stranded two-conductor loudspeaker wire. Ensure that
at least 2 inches of each conductor are separated. Strip away ¼ inch of insulation
from each conductor. Connect the appropriate conductor to each screw terminal,
observing correct polarity. Also, please observe proper speaker wiring when bridging
channels.
Individual Channel Input
10.
All twelve channels have their own dedicated input that allows the connection of
audio sources in addition to the common BUS inputs. This is useful when using the
AMP1200VS with an audio matrix switcher.
AC Voltage Switch
11.
The unit is set at the f
power cord to your wall outlet. For 230V operation, move the voltage selector switch to
the 230V position. When operating at 230V the internal fuse located in the IEC
socket should also be changed. In most 230V applications a separate power cord will
be required and is not included.
12.
IEC Power Connector
The unit comes with an IEC jack that permits removal of the AC power cord. This
allows the flexibility of changing the power cord for different countries. The IEC socket
also houses the main fuse holder. Plug the power cord supplied with the amplifier into
the amplifier and a wall outlet or appropriate surge protector.
CAUTION: DO NOT plug the amplifier’s power cord into a switched outlet, such as
what is provided on some Surround Receivers. If you wish to have the amplifier turn
on when the Receiver is powered up, use one of the power modes, such as Trigger or
Auto.

NOTES ABOUT HUM:
While the AMP1200VS has been designed to minimize the possibility
of hum in the audio system, it is still possible that a hum will occur
in rare circumstances. Its safety grounding can create a path for
small amounts of 60 Hz energy to travel trough the line-level audio
system
. While not dangerous, this energy can cause difficulty with
the auto signal sensing circuit, and at the very least will interfere
with the quiet enjoyment of your system. The first course of action
should be trying to make sure that all of the audio components are
connected to either the same electrical outlet, or at least into the
same circuit branch. Next, cable TV systems are notoriously the
culprit, so be sure to try disconnecting all coaxial feeds that are
connected to the system. If this solves the problem, install a coaxial
line isolator and reconnect the system. In the very worst case, a
line-level audio isolator/transformer connected to the line-in of the
subwoofer amplifier will usually solve the problem.
