ACTIVE 110 INPUT MODULE CONTROLS

1)INPUT- Two channel (stereo) balanced line level input. Connect via XLR male plugs from your signal source.

Use high quality 2 conductor shielded audio cable (Belden 8451) for runs of up to 200'. The XLR pinout is: pin 1 (Shield), pin 2 (Signal high), pin 3 (Signal low).

2)HIGH PASS OUTPUT- Two channel line level balanced output (male XLR) filtered of frequencies below 80 Hz (12 db/octave). Connects to your amplifier for driving full range satellite speakers. Use high quality 2-conductor shielded audio cable (Belden 8451). The XLR pin-out is: pin 1 (Shield), pin 2 (Signal high), pin 3 (Signal low).

3)POWER MODE- Select AUTO-ON for automatic power-up in the presence of an audio signal. In this mode, the unit will revert to stand-by after an audio silence of 15 minutes. Switch to OFF to remove power from the unit. Power OFF will also disable the signal at the HIGH PASS OUTPUT.

THE FOLLOWING CONTROLS ARE FOR THE SUBWOOFER ONLY AND

DO NOT AFFECT THE SIGNAL TO YOUR SATELLITE SPEAKERS

4)PHASE- Subwoofer phase may be switched to 0 or 180 degrees to match the phase of your full range drivers. The switch is in the correct position when the system exhibits an increase in LF output when switched at a sustained level. NOTE: Be sure all full range loudspeakers are wired in common phase during installation.

5)LF BOOST- Adjusts up to a 4 dB boost at frequencies below 60 Hz for a more dramatic low end performance.

6)EARTH LIFT- Switches the internal ground connection from chassis to "floating" to help eliminate any possible ground-loops that may cause hum or buzzing in the subwoofer or other pieces of gear.

7)X-OVER MODE- The LOW PASS position is used in most installations. ALL PASS presents a full range signal to the subwoofer. The ALL PASS mode allows the user to defeat the built-in LOW PASS circuit, which may be useful in certain situations where an external crossover or processor is used.

8)X-OVER FREQ- Used to adjust the LOW PASS frequency of the subwoofer. This control only adjusts the signal going to the subwoofer as the HIGH PASS crossover frequency is fixed at 80 Hz. (Satellite speakers with limited low end response may require a higher crossover frequency for the subwoofer). This control is best adjusted by ear using a high quality music signal.

9)SUB LEVEL- Used to adjust the gain of the subwoofer amplifier without affecting the HIGH PASS output.

OPTIONAL J -BOX- If you prefer to hard wire your installation directly into conduit via a J-Box, please specify with order. Only available in 110SR and 110TB cabinet options.
