SUB-TS18 SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS ¡ Subwoofer-Level Control ™ High-Cut (Low-Pass) Filter Switch £ External Trigger Input ¢ Audio-Sense On/Off Switch ∞ Phase Switch § Line-Level Subwoofer (SUB) Input ¶ Line-Level Full-Range Inputs • Speaker-Level Outputs ª Speaker-Level Inputs , Master Power Switch ⁄ AC Power Cord ¡ Subwoofer-Level Control: Volume may be adjusted using the SubwooferLevel Control. Turn the control clockwise to increase the SUB-TS18's volume, or counterclockwise to decrease it. ™ High-Cut (Low-Pass) Filter Switch: Placing this switch in the ON position activates circuitry that cuts out all audio input signals above 120Hz, allowing the SUB-TS18 to focus its power on reproducing the lowfrequency 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 lowpass filter. The filter has no effect when the SUB Input § is used. £ External Trigger Input: Use the supplied mini-plug cable to connect the trigger output of another product to this jack. When a trigger signal between 3 and 30 volts (AC or DC) is detected, the SUB-TS18 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. ¢ Audio-Sense On/Off Switch: When placed in the AUTO position, and when the Master Power Switch , is turned on, the SUB-TS18 will automatically turn itself on or SUB-TS18 SUBWOOFER AMPLIFIER PANEL CONTROLS AND CONNECTIONS 5
