Overview: The Behringer iNuke NU4-6000 is a lightweight 4-channel amplifier
delivers plenty of power when you need it. Featuring a "back-to-front"
ventilation system, this Class-D amplifier runs cool with "near zero" thermal
buildup. You can use the amplifier on stage connected to a mixer, or for DJ
work. The NU4-6000 is rack-mountable, and requires 2U of rack space (no hardware included).
Built-in 3-way Crossovers: The amp features built-in 3-way crossovers
for each pair of channels (A/B and C/D). Each crossover
can be set to full-range, high-pass, or low-pass operation via a 3-way slide
switch on the rear panel. Full-range mode sends an unfiltered output to the
speakers. In HF mode, frequencies above 100Hz are sent to the speakers, while in
LF mode, low-frequency content below 100Hz is sent to passive subwoofers.
Bridgeable: The NU4-6000's four channels can be bridged into
two outputs. The amplifier will produce 3000 watts when connected to a 4Ω speaker,
or 1600 watts for an 8Ω speaker. A 3-way Mode switches on the rear panel let you
set each channel pair to Bridge mode, dual mono, or stereo mode.
Bi-amping: You can bi-amp a single pair of speakers using
one NU4-6000 amplifier. Bi-amping splits an audio signal into lower and upper
frequency bands, and sends each frequency band to separate speaker cabinets.
Horizontal bi-amping uses two linked channels of the iNuke 4-6000 amplifier to
amplify the low frequencies (Channels A and B), while the other two channels
(Channels C and D) are linked together to handle the high frequencies. Vertical
bi-amping uses one linked pair of channels per stereo side (Channels A and B
amplify the left side, while Channels C and D amplify the right). This requires
an external crossover to separate the low frequencies from the mid/high
frequencies so they can be amplified separately.
Connections: The iNuke NU4-6000 is equipped with four 1/4"-XLR combo inputs. The
four outputs have professional twist-lock speaker connections that are compatible
with Neutrik speakON connectors.
Front Panel Controls: The NU4-6000 features simple operation
with detented rotary gain controls for channels A, B, C, and D. Each control has three
amber signal LEDs that light when signal is present (at -24, -12, and -6 dBFS), and a Clip LED to indicate
when the signal is distorted and needs to be reduced. The gain control knobs
feature amber and red illuminated rings that are easy to see in dark conditions.
Warranty Terms: Behringer offers a 3-year warranty when you
register your product within 90 calendar days of purchase. If the product is
not properly registered, the warranty period is one year.
