For stereo 2-way operation use the markings above the connectors. To
operate the C223 in mono 3-way mode use the markings below the
connectors. The connectors which are not used in the selected mode
are marked "not used". This
Before connecting anything to the crossover, make sure it is not
connected to any power source. Be sure that the source device(equalizer,
compressor, mixing console, etc.) for the C223 is turned off. Connect
the output(s) of the source device to the inputs of the crossover, following
the rear panel markings carefully. Make sure that the amplifiers which will
be used to drive your speaker system are turned off. Using the back
panel markings as a guide, use high quality cables to connect the
Ensure that your C223 crossover conforms to the AC power specifications
in your area, by checking the marked voltage spec on the rear of the unit.
Never plug the incorrect voltage into your crossover, as this may cause
severe damage not covered under the warranty. Connect the power
cord to the crossover first, then to a power source that is properly
After you have safely plugged in the crossover, turn on the source
device(s). Turn the amplifiers' outputs all the way down( ) and turn
on the amplifiers. All of the elements of your sound system should now
be on, and the amplifiers should be turned all the way down. Turn the
source device to its nominal operating level, sending a nominal(average)
level to the C223 .slowly turn up the amplifiers' outputs until you can
hear signal at a cornfortable volume. Make adjustments as you desire.
If you are using your system in stereo 2-way or 3-way mode, the needed
crossover frequency may be higher than 960Hz, making it necessary
to set the x10 switch to the active position. This changes the range of
operation of the frequency selector from 45-960Hz to 450Hz to 9.6kHz.
All other frequency selectors remain the same. When using the x10
switch, ALWAYS ensure that the amplifiers feeding all speaker systems
are turned off or that the input gain controls on the power amplifiers
are turned down before changing the setting of the x10 switch. Not
doing so may send a spurious signal to the outputs of the crossover
when the x10 switch is engaged, and may damage speaker systems
Every output is equipped with a polarity( ) reverse switch on the front
panel. When speakers are not "in phase", the frequency response of
the system is compromised, particularly in the low frequencies. Out of
phase signals can also cause comb-filtering" in the high frequencies.
The polarity switch is extremely useful for fine tuning your sound system
for peak performance. An LED is activated when the output polarity is
