Precision Power D500/1, D2000/1, D3000/1, D1000/1 manual QBASSTM Settings

QBASS PLUS/QBASS REMOTE

On these amplifiers, we’ve taken bass control to a higher level with QBASS PLUSTM. The two QBASSTM switches (labeled 1 and 2) on the front end of the amplifier allow you to select one of four frequency centers 30Hz, 36Hz, 44Hz and 60Hz. On the rear end plate you will find the QBASSTM level control and plug-in for an optional QBASS REMOTETM dash mounted level control. Adjust the level control clockwise for up to +18dB of boost at your selected frequency.

QBASSTM Settings

1	2	Freq.
IN	IN	30Hz
IN	OUT	36Hz
OUT	IN	44Hz
OUT	OUT	60Hz

CAUTION: QBASS PLUSTM should only be used in systems with a strong subwoofer section. +18dB is a tremendous amount of bass boost and may damage your speakers or create excessive distortion if abused.

The optional QBASS REMOTETM: This boost control can be mounted in the dash and will supersede the boost control on the endplate.

The Precision PowerTM amplifiers no longer need an optional QPORTTM to connect multiple QBASS PLUSTM equipped amplifiers while using one QBASS REMOTETM. The new QBASS PLUSTM circuitry in the DCX amplifiers is now positioned before the crossover circuit. In doing this, Precision PowerTM engineers have allowed you to daisy chain your RCA output to the next amplifier input, causing the first amplifier’s QBASS REMOTETM to become the master control amplifier. See your authorized Precision PowerTM dealer for more information!
