Mixed-Mode System On Rear; Full-Range
Speakers On Front
NOTE: Chart values based on 4 ohm speakers.
Figure 7 - 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.
