Interchannel Crosstalk - < -80 dB, 20 Hz to 20 kHz
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); High-Mid/High: 450 Hz to 9.6 kHz; Low-Mid/High-Mid: 450 Hz to 9.6 kHz
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.
Indicators - Stereo Operation (Green); Mono Operation (Yellow); Low Cut (Red-per channel); x10 (Green-per channel); Phase Invert (Red-per output)
