Function Switches:
- Front Panel:
  - Low Cut: Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one switch per channel
  - Phase Invert: Inverts the phase at the output, one switch per output
- Rear Panel:
  - Multiplies the low-high(mono: low/mid and high/mid) crossover frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel
  - Mode: Selects stereo/mono and 2/3/4-way operation
  - LF sum: Selects normal (stereo) or mono-summed low frequency operation and disables Ch 2's low output phase invert LED to indicate that this output is not operational in the LF sum mode

Indicators:
- Stereo Operation: Green LED
- Mono Operation: Yellow LED
- Low Cut: Red LED per channel
- x10: Green LED per channel
- Phase Invert: Red LED per output (3 per channel)
