3 Connections and Control
Features
L.U.C.A.S PERFORMER Subwoofer
1 Limiter LEDs
Much like rev counters, these LEDs indicate the
active system's operating status. For more info, read
the sidebar "More about Limiter LEDs."
2 Power On LED
This LED lights up when the power switch (see rear
panel) is set to On and the system is connected to a
mains power supply.
3 Gain Left/ Right
Operation: Turn the Gain knob all the way down
(counterclockwise) before switching the system on.
Ensure the system is connected to the satellites and
all other connected components are on before
powering it up. Be sure to switch on the connected
mixer as well as all signal sources connected to it,
for example, keyboards, amps, effects, and so forth.
After you power the system up, set the Gain knob to
the 0 dBV or 12 o'clock 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
at this setting. If this is the case, twist the Gain knob
to the far right.)
If you hear distortion or a saturated 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
PERFORMER at the signal source, adjust the input
sensitivity using the Gain knobs. (see also Tips and
Tricks—section 4).

4 Subwoofer Level
Handling: When this knob is set to the 12 o'clock
position, the subwoofer's and the satellite's
respective volumes are matched, ensuring the
proper balance between the subwoofer's bass output
and the stallites' mid/high-range output. If desired,
you can twist the Subwoofer Level knob to the left,
i.e. counterclockwise, to cut the subwoofer's level by
as much as -12 dB and to the right to boost it by as
much as 6 dB.
5 Ground
Ground lift button for separating the signal and
chassis ground in the event of hum. To rid the
system of low-frequency hum, press the Ground
switch in. If this doesn't solve the problem, check all
power and audio cables connected to L.U.C.A.S
PERFORMER for damage, as well as all cables
routing signals to the mixing console (see also Tips
and Tricks in Section 4).
6 Input Left bzw. Input Right (Combination XLR/1/4"
jacks)
L.U.C.A.S PERFORMER is equipped with separate
left and right channel inputs for connecting to a
mixer. Connections: Connect the audio cables that
route the signal coming from your mixer (master
left/right, line out, or a similar circuit) to these
balanced inputs using microphone cables equipped
with XLR connectors. The XLR connectors' pin
assignments must be as follows: 1= ground, 2= +,
3= -. You can also use a 1/4" Tip-Ring-Sleeve plug to
route signals via balanced circuits. Unbalanced sig-
nals can be patched in via a mono plug.

7 Through Left, Trough Right
Connections: Parallel outputs for routing the line
signal (left or right) to other systems, outboard com-
ponents, monitor power amps, etc., via XLR cables.
8 To Satellite Left and Right
Connections: Connect these Speakon
left and right L.U.C.A.S PERFORMER satellites using
speaker cables equipped with Speakon
Note: Be sure to rotate the Speakon
clockwise until they lock in place!
9 Power Switch
Operation: On/off switch for the active system. The
red Power On LED in the upper control panel lights
up when the system is switched on. The active
L.U.C.A.S PERFORMER system should always be
switched on last after you power up all equipment
connected to it, and should be switched off first
before you switch off all the other equipment
connected to it.
