Behringer NX3000 - DSP Controls and Operations; DSP Navigation and Parameter Adjustment; DSP Interface and Screen Display

17 Quick Start Guide
® Step 2: Controls
(3 RACK EARS secure the unit into a rack using
four attaching screws and washers (fasteners
not included). Requires two rack units.
13 VENTILATION openings allow back-to-front
air circulation to prevent overheating.
 INPUT CONTROLS adjust the input level.
To increase signal gain, rotate the knobs
clockwise; to reduce the gain, rotate the knobs
counter-clockwise.
 SIGNAL, LIMIT and PROTECT LEDs display
the signal level and system status for
each channel. The SIGNAL LEDs light to show
the input signal level. The LIMIT LED lights
when the input signal exceeds an optimum
level and activates the internal limiter.
Reduce the input gain if the red LIMIT LED
lights up continuously. The PROTECT LED
shows when an operation error has occurred
(over current, over temperature, and so on).
When an operation error occurs, the PROTECT
LED will light and the unit will automatically
mute the channel until the error is no longer
detected, after which the PROTECT LED will
switch off and the amp will behave normally.
13 SETUP button steps through parameters
within DSP processing modules.
(3 LCD SCREEN displays the current DSP module
and parameter settings.
LE PROCESS button steps through the DSP
processing modules.
13 UP/DOWN buttons step through
DSP modules.
® EXIT button takes you back to the top-level
DSP screen.
® SELECT encoder knob toggles between
Graphic and Edit modes (when pressed) and
changes parameter values (when rotated).
3 INPUTS Route line-level input signals into
these combination jacks using XLR,
balanced W TRS, or unbalanced
<" TS connectors.
 POWER SOURCE jack accepts the included IEC
power cable.
QU OUTPUTS connect the amplifier to the
speakers using professional speaker cables
with twist-locking plugs.
OS PIN OUT MATRIX lists the output pin/channel
configurations available in each speaker
output jack.
QU VENTILATION FAN speed adjusts
automatically to ensure trouble 
free operation.
Q3 USB connection enables firmware updates
and control over parameters via computer.

control software for your computer. The USB
port is for amplifier configuration only.
QU BREAKER (automated fuse, NX6000D).
After eliminating the cause of faulty
operation, simply depress the BREAKER and
power up the unit again. The BREAKER acts in
place of common discardable fuses.
BREAKER WARNING: Take the following actions
BEFORE resetting the breaker:
• Unplug the AC main cable
• Press the POWER button to the extended
"OFF" position
• Turn all input gain control elements down
• And then, reset the breaker, connect the unit to
the mains, switch ON and slowly increase the gain
to the target volume
