LQ™ 10P User Manual

flashing frequently, then the drive level from the mixer (or the Volume control on the LQ 10P) needs to be reduced.

When first powering up the sound system, turn on all upstream electronics first, then the LQ 10P with its Volume control fully counterclockwise (all the way down). Begin checking levels with the mixer output level controls all the way down, then bring them up slowly with the LQ 10P Volume control set to the desired setting (halfway up recommended to start).

USE OF MULTIPLE LQ 10Ps WITH OTHER LQ SERIES POWERED PRODUCTS

The provision of multiple parallel inputs allows the inputs of the LQ 10P to be “daisy-chained” from one to the other. Run the first cable from the mixer to the first LQ 10P, then hook a cable from one of its inputs to the second LQ 10P’s input.This can be continued for several units, depending on the length and total capacitance of all the cables.With a low source impedance, such as a typical mixer output, and typical balanced cables, two or three LQ 10Ps can be daisy-chained from one output using 30' or 40' cables without obvious loss of high frequencies.

The LINK jacks (10) can also be used to connect one other LQ 10P or one other LQ series powered unit and conveniently control levels from just one of the units. Connect a well-shielded 1/4" to 1/4" phone plug patch cord from the Link Out jack of one unit whose input is connected to the signal source, and then plug this cable into the other unit’s Link In jack.The Volume control of the first unit now controls the volume for both identically. Do not connect cables to the jacks while the units are ON and the Volume is turned up! The Link jacks are high impedance single-ended, so do not run this cable too long. Anything over approximately 20'-30' may pick up hum or noise or roll-off the highs.

APPLICATIONS

The LQ 10P has a variety of applications, such as sound reinforcement, public address, side fill system or musical playback.With the optional monitor stand kit, the LQ 10P makes an excellent stage monitor.The LQ 10P is also useful in presentations or karaoke using the mic input and regular line-level inputs in conjunction with one another.

A typical signal source for the line-level inputs (5) of the LQ 10P would be a sound reinforcement mixing console (mixer) or the output from a CD player, Minidisc player or tape deck.

TROUBLESHOOTING

No output at all

First, make sure the unit has AC power and is turned on. If so, the Power LED (4) should be illuminated. If it is not, check that the On-Off switch (3) is in the “On” position; check the IEC power cord connection (2), making sure it is fully engaged and seated. Make sure the AC line cord is plugged into a working AC outlet, and last, check the fuse (1) {see the REAR PANEL/Fuse section for safety instructions}.

Make sure that the inputs of the LQ 10P are receiving a signal by plugging the cable run into the LQ 10P’s inputs to some other device capable of determining this (for example, a power amp and speaker).
