SUB R10/R12

1) Crossover Control: This control determines the highest frequency at which the
subwoofer reproduces sounds. The higher you set the Crossover control, the higher in
frequency the subwoofer will operate, allowing it to mate better with smaller speaker
systems that output less bass on their own.

2) Phase Switch: This switch determines whether the subwoofer transducer's piston-like
action moves in and out in phase with the applied signal. If the subwoofer were to play out of
phase with the main speakers, the sound waves from the main speakers could partially cancel
out the sound waves from the subwoofer, reducing bass performance and sonic impact. This
phenomenon depends in part on the placement of all the speakers relative to the listening
position and to each other in the room as well as the satellite amplifier phase.

3) LF Trim: The LF Trim switch has a range of 0 to +4dB and by default is set at 0. You will
want to adjust this setting depending on your personal preference, equipment, the location of
the subwoofer, and room acoustics.

4) Power On Mode: When switched to 'Auto' position, the subwoofer will then be in
Standby mode. It will automatically turn 'On' when an audio signal is detected at its inputs,
and will return to the Standby mode when no audio signal is detected by its inputs after
approximately 10 minutes. Otherwise, subwoofer will always remain powered until Power
Switch is turned 'Off.'

5) Subwoofer Level: Use this control to adjust the subwoofer’s volume. Turn the knob
clockwise to increase the volume; turn the knob counterclock-wise to decrease the volume.

6) On/Standby LED: When the Power switch is in the ‘On’ position, this LED indicates
whether the subwoofer is in the On or Standby state.

• When the LED glows green, the subwoofer is turned on.

• When the LED glows red, the subwoofer is in the Standby mode.

7) Line In/LFE Input Connectors:

• When you’re connecting the subwoofer to the dedicated subwoofer output of a

receiver/processor that has its own low-pass crossover network, use the LFE Input
connector. When using this input, remember to also set the Crossover Control to ‘LFE’.

• When you're connecting the subwoofer to the preamp or subwoofer outputs of a

receiver/processor that does not have its own low-pass crossover network, use both Line
In connectors. If your receiver/processor only has one subwoofer output you can use either
Line In connector.

8) Power Switch: Set this switch in the ‘On’ position to turn the subwoofer on.

If you will be away from home, or will not be using the subwoofer for an extended period, set
this switch in the ‘Off’ position to conserve energy.

9) Power Cord: After you have made and verified the subwoofer’s input connections, plug the
power cord into an active, unswitched electrical outlet for proper operation of the subwoofer.
DO NOT plug the power cord into the accessory outlets found on some audio components.
