LQ™ 10P USER MANUAL

Special note for permanent installation

When installing the Crest LQ 10P,AC power runs should be used and a certified electrician consulted to be sure that all AC wiring complies with local codes and regulations. Properly affix a cable clip to the cabinet to relieve strain on the IEC power cord connected to the amplifier module at

(2) so the power cord cannot vibrate loose.

USE OF LQ 10P WITH A SUBWOOFER

The built-in pole adapter allows use with the Crest LH 4 double 18" subwoofer system and its accessory pole, Crest part #P00326540.

The pole is 36-3/16" long, with a nominal diameter of 1-3/8".

GETTING A SIGNAL TO THE LQ 10P

There’s a variety of ways to input a signal to the LQ 10P system. Micro- phone input use is covered in a specific section below.The balanced line level inputs allow the use of a 1/4" phone plug, either a standard single- ended (tip-sleeve) plug or a balanced RTS (ring-tip-sleeve) type plug, OR either a male or female XLR plug. Do not connect cables to the jacks while the units are ON and the Volume is turned up!

While the standard, single-ended 1/4" phone plug will work well and the balanced input circuitry will provide some interference rejection, a balanced cable using either the balanced RTS 1/4" phone plug or the XLR plug will provide superior interference rejection and performance.With difficult interference problems, it may be helpful to lift the shield ground on a balanced cable at the LQ 10P end only. Check any input changes carefully, always turning the Volume control down before plugging and unplugging cables.

High-quality premium cables are recommended for the LQ 10P, as these usually have better shielding and materials and will provide greater long- term reliability. It is usually a good idea to leave some slack at the input to the LQ 10P and also to tape the cables down or run them under a cable guard.This may prevent someone from tripping over them or pulling the LQ 10P over when stand mounted.

LEVEL CONTROL ADJUSTMENT

The LQ 10P is equipped with a Volume control to facilitate use in many different applications.With the Volume control adjusted fully clockwise, gain is at maximum and the input sensitivity is 0.5 Volts RMS for full-rated output.When driving the LQ 10P from a mixer, it may be advantageous to reduce the input sensitivity by turning the Volume control to the halfway point.The LQ 10P will now more closely match a typical power amp input.

If the mixer board indicates output signal clipping, then the LQ 10P’s full power capability is not being utilized cleanly. Clipping the signal before it gets to the LQ 10P is not optimal. In this case, reduce the mixer output level and turn up the Volume control on the LQ 10P.

The amplifiers in the LQ 10P are equipped with clipping prevention compression, with an LED indicator to show if compression has engaged. If the sound seems heavily compressed, check this indicator; if the LED is
