NOTE: Chart values based on 4 Ohm speakers.
The amplifier can be configured for a mixed-mode operation. 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 over- lap frequencies, as this may damage the amplifier.
