3 Connections and Control
Features
L.U.C.A.S IMPACT 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 Gain
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
IMPACT at the signal source, adjust the input
sensitivity using the Gain knobs. (see also Tips and
Tricks—section 4).

3 Balance
Operation: Twist the Balance knob to the left or right
to adjust the relative balance of levels between the
left and right channels.
4 Display
Display: The numeric display indicates the currently
selected system configuration (0 to 5).
0 Mute - System switched to silent mode.
Zero sound signal reproduction.
1 Speech - Set-up for speech.
This mode places emphasis upon vocal and spoken
language reproduction. To minimize subsonic inter-
ference and background noise over the microphone,
the subwoofer level is reduced.
2 Live 1 - Set-up 1 for use during live performance.
The Live 1 setup enables punchy, dynamic bass
with rapid transient response. Vocals are likewise
predominant in this sound profile.
3 Live 2 - Set-up 2 for use during live performance.
The Live 2 set-up delivers softer and deeper bass
reproduction at a slightly lower level. The vocals are
slightly less in the foreground when compared to the
Live 1 set-up.
4 DJ 1 - Set-up 1 for reproduction of music from
CDs.
The DJ 1 set-up provides an ideal setting for CD
reproduction, with strong deep bass, discreet
midrange and accentuated highs.
5 DJ 2 - Set-up 2 for reproduction of CD/ MP3
music.
Like DJ1 above, the DJ 2 set-up can also be used for
CD reproduction, but is optimised for MP3-encoded
sources to revitalize the sound with more dynamic
bass, smoother highs and a more natural, less
compressed sound.

L.U.C.A.S IMPACT -- user panel
Note: A flashing display indicates that the controller
has muted the input. This mute function is triggered
via the input signal level. The system is muted when
its level falls below the threshold value. The system
is enabled as soon as the input signal level rises
above the threshold value.
5 Up/Down Buttons
Press these buttons to change system configurati-
ons. Operation: Simultaneously press and hold the
Up and Down buttons for about 1-2 seconds. Once
the letter U (Unlock) appears briefly in the display
you can use the Up and Down buttons to select the
desired setup. The buttons lock again automatically
after a moment, at which time the letter L (Lock)
appears briefly in the display.
6 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.
7 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
IMPACT for damage, as well as all cables routing si-
gnals to the mixing console (see also Tips and Tricks
in Section 4).
