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-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 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

INDICATORS
