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. |
