   FUNCTION SWITCHES

 • Front Panel (Low Cut):

 • Phase Invert:
 • Rear Panel: x1 / x10:


 • Mode:


 • LF sum:

Activates 40 Hz Butterworth, 12 dB/octave high-pass filter,
one switch per channel
Inverts the phase at the output, one switch per output
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
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
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
