OPERATION
CAUTION
The following must be observed to prevent malfunctioning and/or possible equipment damage.
1. Before plugging the unit into the main AC line, make sure that all of the equipment following the crossover output lines is
turned off or all of the inputs are turned down.
2. The unit should be plugged in only when it has been established that the AC line is supplying the correct voltage and
frequency.
3. Never change the frequency range switch from the x10 to x1 position (or vice versa) with the crossover output levels
passing signal. Transients can result and speaker damage is possible.
DESCRIPTION
The CX-2213 are Linkwitz-Riley electronic crossovers. This unit can be used in either of two operation modes, as shown below.
STEREO 2-WAY • MONO 3-WAY
All inputs and outputs are floating and balanced when connected to other floating and balanced equipment. Any combination of bal-
anced and unbalanced operation is permitted. Stereo and mono modes can be easily selected via switch and connecting inputs and
outputs property with no patch cords required.
CD BOOST
The constant directivity horn equalization circuit is to be used with horns that require a high frequency boost. Consult your horn manu-
facturer to determine whether it is needed in your circumstance. The provided boost is +3 db @3.5kHz rising 6db per octave to
22.5kHz. No changes need to be made to operate without the constant directivity boost. If the constant directivity equalization circuit
is desired on a particular channel then depress the corresponding switch labeled "CD BOOST". There is one switch for each chan-
nel located by that channel's input jack. If two or more channels are ganged together, then only use the switch closest to the used
input jack. The switches closest to the unused input jacks have no effect on the circuit when ganged.
PEAK (CLIP) LEDs (LOW & HIGH)
These LEDs will light when the output capability is being exceeded, resulting in clipping distortion. Occasional flickering of the Clip
LEDs is acceptable, but if either remains on continuously you should turn down the level control or reduce the output level of the pre-
ceding component to avoid audible distortion.
RANGE X10
When this switch is set on, the cut off frequency adjusted by the High/Low FREQUENCY ADJUST knob is multiplied by 10.
ON(FX10): 800Hz-10000Hz
OFF(FX1): 80Hz-1000Hz
LOW/ MID/ HIGH PHASE INVERSION SWITCH
These switches invert the phase between the speakers. Use them when you hear a bad sound continuity between the LOW,MID and
HIGH ranges.
