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-way operation LF Sum Switch Selects normal (stereo) or mono-summed low frequency operation and disables Ch 2 low output phase invert LED to indicate that this output is not operational in the LF sum mode.
