2 Safety Notes

The unit corresponds to all relevant directives of
the EU and is therefore marked with
WARNING The unit is supplied with haz-
ardous mains voltage. Leave ser -
vicing to skilled personnel only!
Inexpert handling may result in
electric shock.
G
The unit is suitable for indoor use only. Protect
it against dripping water and splash water,
high air humidity and heat (admissible ambi-
ent temperature range 0 - 40 °C).
G
Do not place any vessels filled with liquid, e. g.
drinking glasses, on the unit.
G
The heat being generated in the unit must be
carried off by air circulation. Therefore, never
cover the air vents (bass reflex openings
between the bass speak ers).
G
Do not set the unit into operation, or immedi-
ately disconnect the mains plug from the
mains socket if
1. there is visible damage to the unit or to the
mains cable,
2. a defect might have occurred after a drop or
similar accident,
3. malfunctions occur.
The unit must in any case be repaired by
skilled personnel.
G
Never pull the mains cable to disconnect the
mains plug from the mains socket, always
seize the plug.
G
For cleaning only use a dry, soft cloth, never
use chemicals or water.
G
No guarantee claims for the unit and no liabil-
ity for any resulting personal damage or mate-
rial damage will be accepted if the unit is used
for other purposes than originally intended,
if it is not correctly connected or operated, if it
is not safely installed or if it is not re paired in
an expert way.
If the unit is to be put out of operation
de finitively, take it to a local recycling
plant for a disposal which is not harmful
to the environment.

3 Applications

This compact line array speaker system consists
of a bass speaker unit and four mid-high range
speak er units. It is designed for professional PA
music applications at events of medium size
and supplies a maximum total power of 1000 W.
The bass speaker unit provides an amplifier for
the two bass speakers and another amplifier for
the mid-high range speaker units to be con-
nected. A digital signal processor (DSP) is con-
nected ahead of the amplifiers. On the one hand,
this processor serves for splitting the signal to
the two amplifiers, on the other hand it offers ver-
satile possibilities for equalizing the frequency
response, readjusting the delay time, and limit-
ing the dynamic range. The DSP configuration is
modified with the supplied software via a PC.
The L-RAY speaker system can be ground
stacked or be mounted in a suspended way
(flown). It may be extended to a maximum of four
systems mounted to each other.
It is supplied with speaker cables for con-
necting the speaker units and mounting material
for the suspended mounting.
