Low cut Switch
|
Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one switch per channel.
|
Phase Invert Switch
|
Inverts the phase at the output, one switch per output.
|
x1 / x10 Switch
|
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 Switch
|
Selects stereo 2-way or mono 3-way operation and disables all LEDs for controls that are non-functional in the selected mode.
|
LF Sum Switch
|
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.
