CROSSOVER FREQUENCIES:
- Stereo Mode: Low/High 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting)
- 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
- Filter type: Linkwitz-Riley, 24 dB/octave, state-variable
FUNCTION SWITCHES:
- Front Panel (Low Cut): Activates 40 Hz Butterworth, 12 dB/octave high-pass filter, one switch per channel
- Phase Invert: Inverts the phase at the output, one switch per output
- Rear Panel: x1 / x10: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: Selects stereo 2-way, 3-way or mono 4-way operation and disables all LEDs for controls that are non-functional in the mono mode
- LF sum: 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 LED
- Mono Operation: Yellow LED
- Low Cut: Red LED per channel
- x10: Green LED per channel
- Phase Invert: Red LED per output (3 per channel)
