1 Input . Speakon
®
NL 4 socket (pin 1+ = +,
pin 1- = -). Insert the Speakon
®
connector and then
rotate it to the right until it engages to establish an
electrical connection. Before unplugging the connec-
tor, you must first disengage the safety catch. To do
this, pull the bayonet catch towards the cord.
3 Setting Up and Connecting
Speakers
Use a cord equipped with standard XLR microphone
connectors or 1/4" plugs to send the signal from
your mixer (master left/right, line out, or a similar
circuit) to the balanced Input jacks. Make sure the
XLR or TRS connectors have the following pin assig-
nments: 1 = ground, 2 = +, 3 = -.
Connect L.U.C.A.S 2000's satellites by plugging the
loudspeaker cords with Speakon connectors into the
Satellite Left and Satellite Right outputs.
Aligning L.U.C.A.S 2000 Satellites Using the
HK AUDIO DuoTilt™
The HK AUDIO DuoTilt™ lets you align L.U.C.A.S
2000 cabinets horizontally in such a way as to
prevent or reduce troublesome ceiling reflections.
The front opening of the HK AUDIO DuoTilt™ gives
you a 7.5° angle of tilt, the rear opening a 15° angle
of tilt.
If you set the full-range cabinets on a fully extended
cabinet tripod or mounting pole, opt for the 15°
angle to minimize ceiling reflections.

4 Operating the System
Ensure the Power On switch is set to Off and the
power cord is clamped into the tab designed to hold
it in place.
Caution: Connecting the L.U.C.A.S 2000 system to
the wrong mains voltage can seriously damage the
power amp!
Turn the Gain knob all the way down (counterclock-
wise as far as the knob will go).
Make sure the system is connected to the satellites
before you power it up, and all connected peripheral
components are switched on first.
Caution! Check that you have turned the Speakon
®
connectors fully clockwise until they are locked in
place!
Switch the connected mixer - as well as the keybo-
ards, instrument amps, effects, and all signal sour-
ces that are connected to it - on first.
Always switch the active L.U.C.A.S 2000 system on
last, that is, after you have switched on all connected
devices. Once you have powered the system up by
activating the Power On/Off switch (it will light up
red when it is set to On and receiving mains power),
set the Left and Right Gain knobs to the center or 12
o'clock position (= 0 dBV).
