Bandwidth 20Hz to 20kHz, +/-0.5dB
Frequency Response < 3 Hz to > 90 kHz, +0/-3 dB
Signal to Noise Ratio Ref: +4 dBu, 22 kHz measurement bandwidth
Signal-to-Noise (Stereo Mode) >94dB (Low Output), >93dB (Mid Output), >92dB (High Output)
Signal-to-Noise (Mono Mode) >94dB (Low Output), >94dB (Low/Mid Output), >92dB (High/Mid Output)
Dynamic Range > 114 dB, unweighted, any output
THD+Noise < 0.004% at +4 dBu, 1 kHz; < 0.04% at +20 dBu, 1 kHz
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)
