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/High450 Hz to 9.6 kHz
  • Low-Mid/High-Mid450 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)

POWER SUPPLY

  • Operating Voltage:100-120 VAC 50/60 Hz; 120 VAC 60 Hz 230 VAC 50 Hz
  • Power consumption: 15W
  • Main Connection: IEC 320 receptacle
