CROSSOVER Operation

Your new POWERCLASS™ amplifier has crossover circuits built-in to provide exceptional system flexibility without the added expense and installation of an outboard crossover. See the frequency detent charts on page 17 to set your amplifier's crossover.

PC4200 / PC4400

The front crossover is high pass and can be adjusted from 20Hz to 5kHz by turning the FRONT HP FREQ. control. If you need full-range, turn the control fully counterclockwise to the 20Hz position. The rear crossover can be high pass or low pass, chosen by the REAR HP/LP switch. The REAR XOVER FREQ. control determines the rear crossover frequency between 20Hz and 5kHz, 20Hz being fully counterclockwise.The RCA outputs are always mono low pass at 90Hz to send a subwoofer signal to another amplifier.

PC4800

The front crossover is high pass and can be adjusted from 20Hz to 5kHz by turning the FRONT HP FREQ. control. If you need full-range, turn the control fully counterclockwise to the 20Hz position. The rear crossover actually consists of two crossovers, one high pass and one mono low pass. The high pass section is a 12dB/octave Linkwitz-Riley type that is adjustable from 20Hz to 5kHz using the REAR HP FREQ. control. For full range operation, turn the control fully counterclockwise to the 20Hz position. The low pass section is a 24dB/octave Linkwitz-Riley type that you can adjust from 44Hz to 315Hz with the REAR LP FREQ. control. High pass or low pass to the rear channel is determined by the REAR HP/LP switch, 'OUT' being low pass and 'IN' being high pass. When you select high pass, the RCA outputs will be low pass and vice versa.

PC6600

The front and rear crossovers are both high pass, and can be adjusted from 20Hz to 5kHz using the XOVER FREQ. FRONT and REAR controls. For full range operation, turn the control fully counterclockwise to the 20Hz position. The subwoofer crossover is a 24dB/octave Linkwitz-Riley type fixed at 90Hz. See system diagrams starting on page 21 for examples!
