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 2/3/4-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.
