IMPORTANT SAFETY INSTRUCTIONS  
When using this electronic device, basic precautions should always be taken, including the following:  
1. Read all instructions before using the product.  
2. Do not use this product near water (e.g., near a bathtub, washbowl, kitchen sink, in a wet basement, or near a  
swimming pool, etc.).  
3. This product should be used only with a cart or stand that will keep it level and stable and prevent wobbling.  
4. This product, in combination with headphones or speakers, may be capable of producing sound levels that  
could cause permanent hearing loss. Do not operate for a long period of time at a high volume level or at a  
level that is uncomfortable. If you experience any hearing loss or ringing in the ears, you should consult an  
audiologist.  
5. The product should be positioned so that proper ventilation is maintained.  
6. The product should be located away from heat sources such as radiators, heat vents, or other devices  
(including amplifiers) that produce heat.  
7. The product should be connected to a power supply only of the type described in the operating instructions or  
as marked on the product. Replace the fuse only with one of the specified type, size, and correct rating.  
8. The power supply cord should: (1) be undamaged, (2) never share an outlet or extension cord with other  
devices so that the outlet’s or extension cord’s power rating is exceeded, and (3) never be left plugged into  
the outlet when not being used for a long period of time.  
9. Care should be taken so that objects do not fall into, and liquids are not spilled through, the enclosure’s  
openings.  
10. The product should be serviced by qualified service personnel if:  
A.  
B.  
The power supply cord or the plug has been damaged.  
Objects have fallen into, or liquid has been spilled onto the product.  
C. The product has been exposed to rain.  
D. The product does not appear to operate normally or exhibits a marked change in performance.  
E.  
The product has been dropped, or the enclosure damaged.  
11. Do not attempt to service the product beyond what is described in the user maintenance instructions. All  
other servicing should be referred to qualified service personnel.

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-2314 are Linkwitz-Riley electronic crossovers. This unit can be used in either of two operation modes, as shown below.  
STEREO 3-WAY • MONO 4-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, MID, 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 one or more remains on continuously you should turn down the level control or reduce the output level of  
the preceding component to avoid audible distortion.  
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.
