How to Connect for Stereo
McIntosh Power Amplifier
McIntosh Audio 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 Au-
dio Control Center or Preamplifier. 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 Au-
dio Control Center or Preamplifier Power Control Out
Jack to the McIntosh PS112 POWER CONTROL IN
Jack.
2. Connect a power control cable from the McIntosh
PS112 POWER CONTROL OUT Jack to the McIntosh
Power Amplifier 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, and then on to the McIntosh Power Amplifier
Power Control Jack.
3. Connect an audio cable from the McIntosh Audio Con-
trol Center or Preamplifier Main Outputs to the McIn-
tosh PS112 LEFT and RIGHT LINE IN Jacks.
Notes: 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 Audio Control Center or
Preamplifier Main Output to the McIntosh PS112
LINE IN on both subwoofers.
4. Connect an audio cable from the McIntosh PS112
LEFT and RIGHT HI-PASS OUT Jacks to the McIn-
tosh Power Amplifier Left and Right Input Jacks.
5. Connect the PS112 power cord to an active AC outlet.
