XT’s Control Features
1 Gain Mic
Twist this knob to adjust the microphone level.
Note:
You can adjust the microphone and line or
auxiliary inputs separately and mix them as desired.
2 Gain Line
This knob adjusts power amp gain to match input
signal levels. In the event that distortion becomes
audible, the incoming signal level is too high. Simply
back off this knob.
3 Gain Aux
This knob adjusts power amp gain to match input
signal levels. In the event that distortion becomes
audible, the incoming signal level is too high. Simply
back off this knob.
4 Limiter Status LEDs
These dual-color LEDs indicate the operating status
of the multi-band limiter. Green = incoming signal,
limiters inactive; yellow = limiter occasionally activated;
red = limiters operating continuously.
5 Mode
If you have just a mono signal available, patch it to
the left input of the Line In or Aux In circuits. Set the
Mode switch to Mono. When you do this, the system
outputs the monaural input signal on both sides (the
left and right).
6 Balance
Use this knob to adjust the relative levels of the left
and right channels.
7 Subwoofer Level
Use this knob to adjust the relative volume of the
subwoofer.
8 Power On LED
This LED lights up when the system is plugged into a
mains power supply and the Power switch (see rear
panel) is set to On.
9 Ground
Ground lift switch for separating the signal and
chassis ground when you encounter problems with
humming noises. The ground circuit is severed when
you press the button in.
Caution:
Never tape over the plug’s ground terminal
– this endangers lives!
10 Mic In
You may plug a microphone directly into this electro-
nically balanced XLR input. (pin 1= ground, 2= +, 3= -).
11 Line In Left/Right
This electronically balanced XLR input is designed
to take mixer signals (pin 1= ground, 2= +, 3= -).
You can also use cables equipped with 1/4" TRS (stereo-
style) plugs (tip = +, ring = -, shield = ground).
12 Aux In
RCA connector designed to take external signal
sources such as (DJ) mixing consoles and CD players.
13 Mix Out
Master output for patching Line, Aux In and Mic In
signals through to other devices such as tape decks
and MD recorders or another L.U.C.A.S
®
XT system.
14 To Satellite Left/Right
Connect these Speakon
®
outputs to L.U.C.A.S
®
XT’s
satellite speakers.
15 Fuse
Mains fuse. In the event of a malfunction, this
fuse will blow, severing the connection between
L.U.C.A.S
®
XT and the mains power supply in order
to protect the system from harm. Replace only with
another fuse of the same type and rating as specified.
16 Mains Input
Use the factory-included power cord to connect this
socket to a mains outlet.
