8 To Satellite Left und Right
Connecting the cables: Connect these Speakon
outputs to the left and right L.U.C.A.S 600 satellite
speakers using cables equipped with Speakon
connectors.
Note: Be sure to rotate the Speakon
clockwise until they lock in place!
9 Fans
These fans keep the power amp modules cool.
Always keep the fan and ventilation vents free of
dirt and debris, ensuring they remain unobstructed
so air can circulate freely.
10 Mains Input
Connecting the cables: Use the factory-included
mains cable to connect from a wall socket to here.
Caution! Make sure the local mains voltage matches
the voltage specified on the device. If you connect
the system to the wrong mains voltage, you may
destroy the electronic components of the
L.U.C.A.S 600 system.
More about Limiter LEDs
Dedicated LEDs indicate the limiter status, one for
the left signal path, one for the right, and one for
the subwoofer.
How do I interpret this display?
The green LED indicates that the input is receiving a
signal. As long as the LED lights up green, the system
is operating at low-to-medium levels, with plenty of
headroom available for the power amps. Yellow
indicates that the system is being pushed close to
its threshold. It's OK if the yellow LED flashes on
and off intermittently, but it should not stay on
continuously. If it does this, back off the volume
on your mixer.
11 Power Switch
® Operation: On/off switch for the active system.
The Power LED in the upper control panel lights
® up red to indicate that the system is on.
® connectors The active L.U.C.A.S 600 system should always be
switched on last, that is, after you switch on all
equipment connected to it; and it should be switched
off first, that is, before you switch off anything that
is connected to it.
12 Fuse
Mains fuse. Always unplug the mains cable before
replacing the fuse! Replace only with another fuse
of the same type and rating (indicated next to the
label Fuse).
13 Mains Cable Tab
Clamp the power cable into the tab to prevent it
from being pulled out inadvertently.
More about pin assignments
The XLR jack's pin assignments comply with the
international IEC 268-12 norm. In accordance with
this norm, pin 1 is the ground, pin 2 carries the
positive signal and pin 3 carries the negative signal.
The stereo-style T-R-S 3/4" jack's tip carries the
positive signal, its ring carries the negative signal,
and the ground circuit is routed via the sleeve.
When you insert an unbalanced mono plug, the
input automatically switches to unbalanced
operating mode.
