may be adjusted using the 

Subwoofer-

Level Control

to increase the SUB-TS15’s volume, or 
counterclockwise to decrease it.

™

High-Cut (Low-Pass) Filter Switch:

Placing this switch in the 

ON

position acti-

vates circuitry that cuts out all audio input
signals above 120Hz. This allows the SUB-
TS15 to focus its power on reproducing the
low-frequency portion of the signal, avoiding

inefficiency and distortion. Engage this filter
when using the 

Speaker-Level Inputs

ª

,

or when using the 

Line-Level Full-Range

Inputs

¶

, unless your receiver or processor

processes its line-level output using a low-
pass filter. The filter has no effect when the

SUB Input

§

is used.

£

External Trigger Input:

Use the sup-

plied mini-plug cable to connect the trigger
output of another compatible product to this
jack. Whenever a trigger signal between

SUB-TS15 amplifier will turn on, even when
the Audio-Sense feature has been activated
by placing the 

Audio-Sense On/Off Switch

in the 

AUTO

position. The amplifier will

remain on for about 10 –15 minutes without
a trigger signal.
