L.U.C.A.S 600 Subwoofer
1 Limiter LEDs
Like the "rev counter" of an engine, these LEDs
8
serve to indicate the limiter's operating status.
2 Gain Left, Gain Right
Operation: Turn the Gain knobs all the way down
(counterclockwise) before powering the system up.
11
Ensure the system is connected to the satellites and
all other components before powering it up. Switch
on the connected mixer as well as all signal sources
connected to it – for example, keyboards, amps,
effects, and so forth – first!
After you power the system up, rotate the Gain Left
and Right knobs to the right to the 0 dBV setting.
This is the preferred level if you have connected
a mixer.
Note: If you connect a CD player or a keyboard directly
to the system, you may not be able to achieve peak
volume.
If you hear distortion or an overdriven signal, first
check the signal sources and, if possible, reduce the
output signal level there. If you are unable to turn
down the level of the signal sent to L.U.C.A.S 600
at the signal source, adjust input gain using the
Gain knobs. (see also Tips and Tricks)

3 Subwoofer Level
Operation: When set to the center position, the
subwoofer's volume is matched to the satellites'
levels to achieve a balanced sound with an even
distribution of low frequency (subwoofer) and high
frequency (satellite) signals. If you want to boost or
cut low frequencies, simply rotate the Subwoofer
Level knob to the left down to -12 dB or right up
to +6 dB.
4 Power-On LED
This LED lights up when the Power switch (see rear
panel) is set to On and the system is plugged into
a mains power supply.
5 Ground
The Ground Lift button is intended to separate the
signal ground from the chassis ground in the event
of hum. If you encounter low frequency hum, activate
the Ground Lift switch. If this doesn't solve the
problem, check all cables connected to L.U.C.A.S 600
for damage, as well as all cables that are carrying
signals routed to the mixing console (see also Tips
and Tricks). The ground circuit is interrupted when
this button is pressed in.
6 Input Left and Input Right (Combination XLR/-
3/4" jack ports)
L.U.C.A.S 600 is equipped with separate left and
right channel inputs to accept the signals coming
from the mixer outputs.
Connecting the cables: Connect the cables that carry
the signal coming from your mixer (master left/-
right, line out, or a similar circuit) to the balanced
inputs using a microphone cable equipped with XLR
connectors. The XLR connectors' pin assignments
must be as follows: 1= ground, 2= +, 3= -.
You can also use a 3/4" Tip-Ring-Sleeve plug to route
signals via balanced circuits. Unbalanced signals can
be patched in via a mono plug.
7 Through Left, Through Right
Connecting the cables: These are parallel output
for routing the incoming Line signals (left or right)
to other systems, outboard components, monitor
power amps, etc., via XLR cables.
