CROSSOVER and GAIN CONTROL

C r o s s o v e r

Your new POWERCLASS™ amplifier has a 90Hz fourth-order Linkwitz-Riley type, 24dB per octave phase correlated crossover built in to provide system flexibility without the added expense and installation of an outboard crossover. The speaker outputs of your amplifier are high pass or low pass according to the HP/LP switch on the front endplate.

You would choose low pass (switch out) to use this amp for subwoofers, or choose high pass (switch in) to use this amp for full range speakers. The RCA outputs are controlled by the same HP/LP switch, but are always the inverse of the speaker output crossover. If the HP/LP switch is out (LP) the RCA outputs will be high pass, and if the HP/LP switch is in (HP) the RCA outputs will be low pass. In addition, the speaker outputs can be all pass (no crossover) by setting the XOVER ON/OFF switch to the off (out) position.

NOTE: The RCA outputs are always crossed over.The System Diagrams beginning on page 14 show several ways to use the internal crossover in your system.

1. Adjust all amplifier input gain controls to just above minimum sensitivity (fully counterclockwise).

2.Using the cleanest source (CD), with music playing turn up the head unit until you can hear distortion. Now turn it down a bit until you cannot hear the distortion.

3.Increase the Amplifier gain (clockwise) until the onset of audible distortion. Then decrease the gain to the point just before the distortion starts. This setting minimizes background noise and prevents overload.

4.Repeat step 3 for any remaining amplifiers in the system.
