Mixed Mode System On Rear, Full Range Speakers On Front
The amplifier can be configured for a mixed-mode operation on either
channels 1/2 or 3/4 amplifier sections. The table provides component
values to create a 6dB per octave crossover at specified frequencies. Use
components that have a +
5% tolerance and capacitors rated at 100V.
NOTE: Choose the same frequency for both LP and HP crossovers. Do not
overlap frequencies, as this may damage the amplifier.
