Subwoofer-Level Control: Volume

may be adjusted using the Subwoofer-Level Control. Turn the control clockwise to increase the SUB-TS7’s volume, or counterclockwise to decrease it.

High-Cut (Low-Pass) Filter Switch: Plac-

ing this switch in the ON position activates cir- cuitry that cuts out all audio input signals above 120Hz. This allows the SUB-TS7 to focus its power on reproducing the low-frequency portion of the signal, avoiding inefficiency and distor- tion. Engage this filter when using the Speaker- Level Inputs , or when using the Line-

Level Full-Range Inputs , unless your

receiver or processor processes its line-level out- put using a low-pass filter. The filter has no

effect when the Sub Input is used.

Trigger Input: Some receivers or sound processors have a Trigger Output that sends a signal to the subwoofer to switch on or off. If your receiver has such a Trigger Output, connect it here. When placed in the AUTO position, and

when the Master Power Switch is turned on, the subwoofer will automatically turn itself on or place itself in the Standby mode, depending on the status of your receiver or processor.. When this switch is placed in the ON position, the SUB-TS7 will remain on, whether or not it is receiving an audio signal.

An LED located on top of the SUB-TS7 indicates whether the SUB-TS7 is in the On or standby state when used with the Trigger On/Off

Switch in the AUTO position. The LED is lit blue to indicate that the SUB-TS7 is receiving an audio signal and is turned on, and the LED is lit amber to indicate that no signal is being received and the SUB-TS7 is in Standby mode.

When the Trigger On/Off Switch is in the

ON position, the LED will be lit blue, whether or not an audio signal is present.

When the Master Power Switch is turned

off, the LED goes dark, no matter which position

the Trigger On/Off Switch is in.

Phase Switch: This switch determines whether the SUB-TS7 subwoofer’s piston-like action moves in and out in phase with the main speakers. If the speakers were to play out of phase, the sound waves produced by the sub- woofer would be cancelled out, reducing bass response. This phenomenon depends in part on the relative placement of the speakers in the room. In most cases, the Phase Switch should be left in the NORMAL position. How- ever, it does no harm to experiment with the Phase Switch , and you may leave it in the position that maximizes bass response.
