Operating instructions

OPERATION

FRONT PANEL CONTROLS

POWER SWITCH

The POWER switch applies and removes power to the unit. Make sure that all equipment after the

CX310 is either off or the outputs are turned all the way down before turning the CX310 on or off.

CLIP INDICATORS

Separate HIGH and LOW CLIP indicators are provided for each channel of the CX310. These

indicators will light at approximately 3dB before clipping occurs in any stage of the channel. To

prevent overloading the channel, either turn down the CX310 input control or turn down the output

level of the piece of equipment feeding the CX310 (i.e. mixer, equalizer or other piece of processing

equipment.).

INPUT LEVEL CONTROLS

An INPUT LEVEL control is provided on each channel of the CX310. If you are using the CX310 as a

mono 3-way crossover, the Channel One INPUT CONTROL is the only one used. The INPUT LEVEL

control should be set at its 0 marking in most cases. Increasing or decreasing gain should only be

done to make up for deficiencies in other parts of the system.

MUTE SWITCHES

MUTE switches are provided for each output on the CX310. These are intended for use when setting

up your system and testing either the crossover frequency point or the separate amplifiers and

speakers they are feeding. These switches allow you to isolate a specific frequency output on a

specific channel for fine-tuning or troubleshooting. It is not recommended that you mute or un-mute

any frequency band during normal usage. Levels should be turned down when the MUTE switches

are activated or de-activated.

LOW AND HIGH OUTPUT LEVEL CONTROLS

Each channel of the CX310 has LOW and HIGH OUTPUT LEVEL controls. These controls are used

to trim the output levels to the LOW and HIGH OUTPUT jacks on the rear of the unit, respectively. If

you are using the CX310 as a mono 3-way crossover, the Channel One LOW OUTPUT LEVEL

control sets the level of the LOW OUTPUT, the Channel Two LOW OUTPUT LEVEL control sets the

level of the MID OUTPUT, and the Channel Two HIGH OUTPUT LEVEL control sets the level of the

HIGH OUTPUT.
