3. BUS Line Inputs / Outputs
The AMP1200 has t
wo common or BUS inputs that 
recei
ves audio signals from standard line-level audio 
sources and sends them to a
ny 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 ca
bles that feature low impedance, shielding 
and high quality connector
s.
4. Remote Turn-On Switch
This
 switch selects the turn-on stimuli that will put the ampli -
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. 
minutes to return from ready to standby mode.
5. Trigger Input / Output
The
 trigger input is a handy feature when connecting the 
plug 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 AMP1200 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 AMP1200 can also provide 
an
 output trigger voltage (12DC @500mA max.) to turn on 
and
 off other devices in the audio system. When the ampli -
Note :  Remember  there  is  a  delay  of  approximately  15 
mi
nutes before the amplifier goes to standby when using 
the
 “Auto” turn-on mode.
6. Channel Gain Control
Each channel has its 
own independent level adjustment. 
This all
ows the output level of each speaker to be per -
fectly matched to its area. It can also be used to limit the 
maxi
mum audio level in a certain area. 
7. Bridging Switch
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 
oh
ms. 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 b
ridged mode and “ST” is non-bridged or stereo mode. 
CAUTION:  Only change switch positions when the 
amplifier is tu
rned off.
8. Input Selection Switch
Each channel is capa
ble of delivering the source from 
ma
ny 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 pl
ay source connected to that 
channel
’s LINE IN). 
CAUTION:  Only change switch positions when the 
amplifier is tu
rned off.
9. Speaker Output Terminals
The
 AMP1200 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 sepa
rated. Strip away 
¼ inch of insulation from each conducto
r. Connect the 
approp
riate conductor to each screw terminal, observing 
correct pola
rity. Also, please observe proper speaker wir -
ing when b
ridging channels.
10
. Individual Channel Input
All t
welve channels have their own dedicated input that 
all
ows the connection of audio sources in addition to 
the common 
BUS inputs. This is useful when using the 
AMP1200 with an audio mat
rix switcher. 
11
. AC Voltage Switch
The
 unit is set at the factory for 115V U.S. operation; simply 
connect
 the included IEC 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 ja
ck that permits removal of 
-
ing the p
ower cord for different countries. The IEC 
socket also houses the main fuse holde
r. 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 Sur -
round Recei
vers. If you wish to have the amplifier turn on 
when the Recei
ver is powered up, use one of the power 
mode
s, such as Trigger or Auto.
