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:
x1 / x10:

Multiplies the low-mid (mono: low/low-mid) crossover frequency range of the front-panel markings by a factor of 1 or 10, one switch per channel

Mode:

Selects stereo 2-way, 3-way or mono 4-way operation and disables all LEDs for controls that are non-functional in the mono mode

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
