3.L/H OUTPUT LEVEL CONTROLS:

These are used to adjust the output level of each way: LOW and HIGH .

4.LOW CUT BUTTONS FOR LOW WAY:

These insert low cut filters in the LOW way of each stereo channel with a 12dB/Octave, 30 Hz HPF to minimize problems from subsonic frequencies in the signal, to suppress hum, and to prevent low frequency speaker resonance.

5.PHASE BUTTONS:

These allow switching the polarity to invert the signal phase on the HIGH ways. This is done after the output levels are set to correct audible phase problems.

Caution: Before pressing the PHASE BUTTON, always lower the outputs of your power amplifiers to avoid possible speaker damage.

6.SUB CROSSOVER FREQUENCY CONTROL:

This selects the crossover frequency of the SUB WOOFER way. You can select the frequency between 50 Hz to 250 Hz.

7.SUBWOOFER OUTPUT LEVEL CONTROL:

This is used to adjust the SUB WOOFER output level.

8.SUBWOOFER LOW CUT BUTTON:

This inserts a low cut filter in the SUBWOOFER way with a 12dB/Octave, 30 Hz HPF to minimize problems from subsonic frequencies in the signal, to suppress hum, and to prevent low frequency subwoofer speaker resonance.
