BEHRINGER NX3000 Power Amplifier

Load-in just got lighter.

The van is packed, the stairs are steep and the amp rack is next. The NX3000 is a Class-D amplifier that weighs 3.5 kg and needs two rack units. Carry it in, plug it in and start the soundcheck.

Stereo, bridge or bi-amp

A MODE switch selects MONO, STEREO or BRIDGE. The CROSSOVER switch selects FULLRANGE, LF or HF. In LF mode, the amp amplifies only the low frequencies. LF and HF modes are typically used for bi-amping. For example, one NX amplifier handles the highs and a separate NX amplifier handles the lows.

See what each channel is doing

SIGNAL, LIMIT and PROTECT LEDs show the state of each channel. If the red LIMIT LED lights continuously, reduce the input gain. After an operation error, the amp mutes that channel until the error clears.

Connections you already use

Combination inputs take XLR, balanced ¼" TRS or unbalanced ¼" TS plugs. Speaker outputs connect through speaker cables with twist-locking plugs. The fan speed adjusts automatically, and the IEC power cable is included. Rack screws and washers are not included.

Features

• SmartSense impedance compensation: a class-D power amplifier with SmartSense loudspeaker impedance compensation
• Stereo output power: 2 x 1500 W into 2 Ω, 2 x 900 W into 4 Ω and 2 x 440 W into 8 Ω per channel in stereo
• Bridge output power: 3000 W into 4 Ω and 1500 W into 8 Ω in bridge connection
• Three amplifier modes: the sliding MODE SWITCH selects MONO, STEREO or BRIDGE
• Built-in crossover switch: FULLRANGE, LF or HF; in LF mode the unit amplifies only the low frequencies, in HF mode only the high frequencies
• Bi-amping: LF and HF modes are typically used in bi-amping applications
• Channel status LEDs: SIGNAL LEDs at -40 dB, -6 dB and -3 dB, a 0 dB LIMIT LED and a red PROTECT LED on each channel
• Internal limiter: the LIMIT LED lights when the input signal exceeds an optimum level and activates the internal limiter
• Amplifier protection: thermal and DC protection, with on/off muting and DC-fault power supply shutdown for load protection
