1. ON/OFF SWITCH:
Caution: Always turn the Crossover ON before the amplifier, and turn it OFF after the amplifier or transients harmful
to the speakers may result .
2. L/M/H OUTPUT LEVEL CONTROLS:
These are used to adjust the output level of each way : LOW, MID and HIGH .
3. LOW CUT SWITCHES 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.
4. MH CROSSOVER FREQUENCY CONTROLS:
These select the crossover frequencies of the MID and HIGH ways. They’re a low cut for the HIGH and a high cut
for the MID. You can select the frequencies between 480 Hz to 7 kHz.
5. LH CROSSOVER FREQUENCY CONTROLS:
These select the crossover frequencies of the LOW and MID ways. They’re a low cut for the MID and a high cut for
the LOW. You can select the frequency between 70 Hz to 1 kHz.
6. PHASE SWITCHES:
These allow switching the polarity to invert the signal phase on the MID and HIGH ways. This is done after the output levels are set to correct audible phase problems.
Caution: Before pressing the PHASE switches, always lower the outputs of your power amplifiers to avoid possible
speaker damage.
7. 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.
8. SUBWOOFER OUTPUT LEVEL CONTROL:
This is used to adjust the SUB WOOFER output level.
9. SUBWOOFER LOW CUT SWITCHES:
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.
10. AC CORD
11. L/M/H OUTPUT CONNECTORS:
Connect to your amplifiers via these balanced XLR output jacks.
12. STEREO INPUT CONECTORS:
Connect your L/R stereo input signal to these balanced XLR input jacks.
13. SUBWOOFER OUTPUT CONECTOR:
Connect to your subwoofer amplifier via this balanced XLR output jack.
14. AC VOLTAGE SELECTOR SWITCH:
Before plugging in the power cord, check to see that the unit is set for the proper voltage for your area: ~115V
(60Hz) or ~230V (50Hz).
15. FUSE COMPARTMENT :
Replace with only the same type fuse (0.5A/250V). If it blows continuously, do not use the unit until it has been serviced by qualified personnel.
