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).

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.

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.

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).
