Connecting The Ten OR Twelve

Caution: Before connecting the Ten OR Twelve to your audio system, it is important to unplug or turn off all AC power connections to connected components such as receivers, amplifiers, preamplifiers, and processors. Do not plug in or connect the Ten OR Twelve subwoofer to AC power until all connections have been made.

Integrating the Ten or Twelve into your surround system is simple and straightforward when using this connection method. Your AV Receiver will control all crossover functions and the Ten or Twelve will control Subwoofer gain, phase and boundary equalization.

Connect the Subwoofer/LFE Output on your AV Receiver to the LFE IN on the back of the Ten or Twelve. (Fig. 2)

(1)Power Mode - Leaves Subwoofer in permanantly on (ON), or puts the subwoofer in automatic standby mode (AUTO).

(2) Power Indicator - The light is green when the sub- woofer is on. The light is amber when the subwoofer is in stand-by mode. The light is red when the subwoofer is in protection.

(3)Volume Control - Adjusts the loudness of the subwoofer independently of the main speakers.

(4)Low-Pass Filter - Continuously variable low-pass crossover control.

(5)Boundary Switch - Selects response mode of subwoofer, depending on placement.

(8)LFE In/Out - Low level RCA input jack for LFE or subwoofer signal. Out is an unbuffered pass through used for multiple subwoofers.

(9)Hi Level Input - Speaker level input connector.

(10)Power Switch - Turns the unit on and off

(11)Fuse Holder - location of the user servicable fuse
