CONTROLS AND CONNECTIONS
CONTROLS
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.
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.
4.
L/H OUTPUT LEVEL CONTROLS:
These are used to adjust the output level of each way: LOW and HIGH .
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.

6.
PHASE SWITCHES:
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 switches, always lower the outputs of your power amplifiers to
avoid possible speaker damage.
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.
8.
SUBWOOFER OUTPUT LEVEL CONTROL:
This is used to adjust the SUB WOOFER output level.
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.
CONNECTION
9.
FUSE COMPARTMENT:
Replace with only the same type fuse (1.0A/250V). If it blows continuously, do not use the unit
until it has been serviced by qualified personnel.
10. STEREO INPUT CONECTORS:
Connect your L/R stereo input signal to either the balanced XLR or the unbalanced 1/4" input jacks.
11. OUTPUT CONECTORS:
Connect to your amplifiers via these unbalanced 1/4" output jacks.
