QUICK START UP

If you’re like most new owners, you’re probably in a hurry to plug your CX mixer in and use it. Here are some brief instructions to get you going quickly. With the mixer unplugged and turned off complete the following procedures:

1.CONNECTING AC POWER TO YOUR MIXER

•Check the rear panel to make sure the mixer received uses the proper AC Line Voltage. (USA 120VAC, Europe 240 VAC ...etc.)

•Use only a grounded (3 prong) power outlet to prevent a shock hazard. This gives the quietest grounding for your mixer.

2.CONNECTING SPEAKERS

•For connecting speakers, use the two 1/4” speaker jacks on the rear panel. These jacks are controlled by the main level control on the front panel. The speaker cables should be non-shielded and at least 18 gauge(AWG) wire. For speaker cable runs of over 20 feet 16 gauge wire is recommended.

NOTE: Do not run your speakers through microphone cables, guitar cables, or multi-conductor microphone junction boxes or “snakes” as they are sometimes referred to. This wire is normal- ly shielded and of a very light gauge causing a substantial loss of power and oscillations at high frequencies in the amplifier. All speaker wires must be non-shielded.

3.CONNECTING INPUTS TO YOUR MIXER

•For low level balanced devices such as microphones, plug into the balanced MIC inputs using an XLR shielded microphone cable.

•For high level unbalanced devices such as Tape Recorders and Keyboards plug into the LINE input jacks using a 1/4” phone shielded cable.

4.TURNING YOUR MIXER ON

•Adjust all channel and master level controls to the off position (fully counter clockwise).

•Adjust all “EQ” tone controls, the channel’s Hi, Mid, and Lo and the master 9 Band Graphic EQ, to their center detent position.

•Turn the mixer on by the rear panel power switch and watch for the power LED to come on.

MAINTENANCE

To bring back the new look, your CX mixer can be washed with mild detergent and/ or a warm damp soft cloth. This will remove normal dust and oil from the front and back panels. Never spray cleaners or detergents directly at the unit. The mixer’s are virtually sealed from outside dust and dirt, but it is recommend- ed to keep the mixer free from dust, dirt, and moisture as much as possible.
