| 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/mono and 2/3/4-way operation |
| 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. |
