[. . . ] POWER TERMINALS S/N ratio >90dB RCA jacks used to connect to the bass amplifier line inputs. Allows you to change the phase of your subwoofer 0 or 180 degrees to help compensate for timing differences between drivers. For selection of stereo or mono mode subwoofer output. Channel separation 60dB THD 0. 07% Power supply 10-16V DC, negative ground Dimensions 1. 8"H x 7. 9"W x 4. 8"D 5 Use these connectors to deliver power, ground and remote turn-on control to the unit. REMOTE CONTROL UNIT 1 Q SELECT This control will narrow or widen the boost frequency bandwidth (Q=factor) being sent to the amplifier for each band from Q=20(Narrow bandwidth, steep slope) to Q=2 (Wide bandwidth, gentle slopes). [. . . ] Slowly turn the volume up and listen carefully for: obvious trouble in sound (distortion, no sound, no hiss, total silence). Turn the system off refer to "Trouble Shooting Guide" at this manual. 8 Caution DO NOT ROUTE AUDIO CABLES AND POWER CABLES TOGETHER!THIS CAN CAUSE ENGINE NOISE IN YOUR AUDIO SYSTEM. ALWAYS DISCONNECT THE SYSTEM FROM THE BATTERY BEFORE ATTEMPTING TO MAKE OR ALTER ANY CONNECTIONS. THIS PRODUCT IS DESIRED FOR USE IN ANY 12 VOLTS NEGATIVE GROUND ELECTRICAL SYSTEM ONLY. INSTALLING THIS PRODUCT IN ANY POSITIVE GROUND ELECTRICAL SYSTEM COULD SERIOUSLY DAMAGE THE AUDIO SYSTEM. The Bass Driver provides variable enhancement of bass frequencies. The level of peak boost varies from 0 to +12dB and the frequency at which peak boost occurs is adjustable from 40Hz to 400Hz. 20-Q to 2-Q boost characteristic can be adjustable. 2-Q characteristic boosts a wide range of frequencies and is useful for general sound quality enhancement. The 20-Q characteristic boosts a narrow range of frequencies and can be used to tune a subwoofer system fo rmaximum output. The Bass Driver Q adjustable should be set to the 2-Q(wide) position and the frequency control set approximately one octave below the subwoofer's resonant frequency. In vented enclosures, the roll off of the system is quite steep below the tuning frequency (typically 24dB/octave). In this case, the bass driver should be set for 20-Q(narrow) operation. Never set the Bass Driver boost frequency below a vented enclosuer's turning frequency. For maximum output from a vented enclosure, set the Bass Driver boost frequency to the tuning frequency of the enclosure. These adjustments can be made with the Bass Driver in the signal path, but make sure the effect is turned off (remote level Min. ) then verify operation of the Bass Driver by increasing the boost level while listening for changes in subwoofer response. Once operation of the Bass Driver is confirmed, adjustment can proceed. Adjusting The Bass Driver TBOUBLE SHOOTING GUIDE PROBLEM 1.
