JB Sytems D2-0900 2x450W RMS, 4 Ohm / 900W RMS Bridge

Professional 2-channel amplifier with built-in active crossover.

Power stereo 4 (1kHz, THD+N<0,1%) = 2x 450Wrms

Power bridge 8 (1kHz, THD+N<0,1%) = 900Wrms

Very compact housing, only 2U (88mm) high

Oversized power supply guarantees a powerful bass reproduction

Built-in active crossovers: no need for separate crossover units to setup an active system.

Each channel equipped with a 24dB/octave crossover: adjustable crossover point (90~250Hz) and 3 operation modes: HPF (high pass filter) + LPF (low pass filter) + OFF (no filter)

Two amplifier modes: stereo and bridge

Peak limiters can be switched on/off

Soft start power supply

Very efficient cooling

DC fault protection

High temperature protection

Overload and short circuit protections

Balanced inputs with combo connectors (jack + XLR)

XLR-outputs: daisy chaining of several amplifiers

3 Speakon® outputs: left + right channels + bridge

3 models with different output power available
