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 reso-
nance.
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 out-
put 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 serv-
iced by qualified personnel.
