CROSSOVER FREQUENCY CONTROLS:
These select the crossover frequencies of the LOW and
HIGH ways. They’re a low cut for the HIGH and a high
cut for the LOW. You can select the frequencies
between 250 Hz and 6 Hz.
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:
