CONNECTION CABLES
In this chapter you'll find the wiring diagrams for the connectors to be used with your crossover.
Take care of the connector cables, always holding them by the connectors and avoiding knots
and twists when coiling them: this gives the advantage of increasing their life and reliability,
which is always to your advantage.
Periodically check that your cables are in good condition, that they are correctly wired and
that all their contacts are perfectly efficients: a great number of problems (faulty contacts,
ground hum. discharges, etc.) are caused entirely by using unsuitable or faulty cables.

5 PHASE SWITCHES
:
These allow switching the polarity to invert the signal phase on the HIGH ways. This is
done afterthe 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.
This selects the crossover frequency of the SUB WOOFER way. You can select the
frequency between 50 Hz to 250 Hz.
This is used to adjust the SUB WOOFER output level.
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.

Your unit may have the AC Voltage Selector (~115V/60Hz or ~230V/50Hz) built into the
Fuse Holder. With a small screw driver pull/pop out the Fuse Holder and rotate it so
that the arrow showing the proper voltage in your area points toward the other arrow
in the upper left comer of plug assembly, and re-insert.
Connect your L/R stereo input signal to either the balanced XLR or the unbalanced
1/4" input jacks.
Connect to your amplifiers via these unbalanced 1/4" output jacks.
Use the enclosed power cord to connect the unit to the mains.
