The Punch 250.2 Power amplifier has a crossover switching network which enables you to:

•“Audiophile Bypass” the 250.2 and Pass-Thru

•Configure a 12dB per octave filter for both 250.2 and Pass-Thru

•“Audiophile Bypass” the 250.2 and configure a 12dB per octave filter for the Pass-Thru

•Configure a 24dB per octave filter for the 250.2 and “Audiophile Bypass” the Pass-Thru

•Configure a 12dB per octave bandpass filter for the 250.2 and “Audiophile Bypass” the Pass-Thru

The crossover switching network allows the crossover to be distributed to the amplifier and Pass Thru in many different configurations. The orientation of both switches configure the distribution pattern to where the crossover signal will be routed.
