How to Operate the PS112 in Stereo

Level Control

Start with the LEVEL CONTROL in the center position and adjust until the subwoofer volume is matched to the rest of the system when listening to a full-range source.

Bass Enhance

Set the BASS ENHANCE Switch to MUSIC, turning the BASS ENHANCE effect off. Careful listening with this circuit switched to MUSIC and then listening with it switched to VIDEO will help determine if this effect will be beneficial to the system.

Sub Frequency

When used with a full-range input, the SUB FREQUENCY Control should be set to the highest frequency the subwoofer is to reproduce.

Hi-Pass Frequency

When used with a full-range input, the PS112 could be used with a preamplifier, a separate amplifier and a pair of loudspeakers. The HI-PASS FREQUENCY Control should be set to the lowest frequency the left and right loudspeak- ers are to reproduce.

Phase

The PHASE Switch sets the acoustic output phase of the PS112 to either 0 or 180 degrees relative to its input. This switch is to help avoid phase cancellation (characterized by a loss of bass information) between the PS112 and any other low frequency producing speaker in the system. Careful listening with this circuit switched to 0 and then listening with it switched to 180 will help you determine if this effect will be beneficial to the system. Set the switch to the desired bass.

Remote Power Control

The turn-on method uses a turn-on signal from a McIntosh Control Center or Preamplifier. When a Power Control Cable is connected between the Control Center or Pream- plifier and the PS112, the signal-sensing circuit is disabled and the PS112 will always be on whenever the Control Center or Preamplifier is on. The PS112 also has a Power Control OUTput jack for triggering additional subwoofers or other McIntosh component(s).

The PS112 utilizes signal-sensing circuitry for its turn- on method. In this mode, the PS112 turns on when a music signal is detected at the Line INput(s). A time delay of thirty minutes is incorporated in the circuit to prevent the PS112 from turning off during a music or movie passage where there is little low frequency activity. This turn-on method is beneficial when running an additional Power Control Cable is not feasible.
