Crossover Frequencies (Stereo Mode)	Low/High: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting)
Crossover Frequencies (Mono Mode)	Low/Mid: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting); Mid/High: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting)
Crossover Filter Type	Linkwitz-Riley, 24 dB/octave, state-variable
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.
