FUNCTION SWITCH
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
INDICATOR
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)
