| 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), >92dB (High Output) |
| Signal-to-Noise (Mono Mode) | >94dB (Low Output), >93dB (Mid Output), >92dB (High 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); Mid/High: 45 to 960 Hz or 450 Hz to 9.6 kHz (x10 setting) |
| 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) |
