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/mono and 2/3-way operation

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.
