How to Connect for Home Theater
McIntosh Six Channel Power Amplifier
McIntosh A/V Control Center
The McIntosh PS112 Powered Subwoofer may be turned
On or Off by two different methods. The preferred method
is to utilize the Power Control Signal from a McIntosh A/V
Control Center or Surround Decoder. If the Power Control
Signal is not available, the PS112 has built-in signal-sens-
ing circuitry which will automatically turn-on the
subwoofer.
1. Connect a power control cable from the McIntosh A/V
Control Center or Surround Decoder Power Control
Out Jack to the McIntosh Power Amplifier Control In
Jack.
2. Connect a power control cable from the McIntosh
Power Amplifier Out Connector to the McIntosh PS112
POWER CONTROL IN Jack.
Note: If two or more McIntosh PS112 Powered
Subwoofers are being used in the same system,
connect the POWER CONTROL OUT from the first
PS112 to the next PS112 POWER CONTROL IN
Jack.
3. Connect an audio cable from the McIntosh A/V Control
Center or Surround Decoder Subwoofer Out to the
McIntosh PS112 RIGHT or LEFT LINE IN.
Notes: 1. If two or more McIntosh PS112 Powered
Subwoofers are being used in the same system,
use a Y Adapter to connect audio cables from
the McIntosh A/V Control Center or Surround
Decoder Subwoofer Out to the McIntosh PS112
LINE IN on both subwoofers.
2. The PS112s Power Control will function with 5
to 20 volts applied to the Power Control Input.
Use a 1/8 inch stereo mini phone plug to connect
to the Power Control Input.
3. If the input signal is insufficient for proper
system balance, connect the cable from the
McIntosh A/V Control Center or Surround
Decoder Subwoofer Out to a Y adapter and
connect the Y adapter outputs to both the
LEFT and RIGHT LINE IN Jacks. This will
increase the input gain of the PS112 by 6dB.
4. Connect the PS112 power cord to an active AC outlet.
