:: Product Description

 

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

     * Power stereo 4Ω (1kHz, THD+N

     * Power bridge 8Ω (1kHz, THD+N

     * 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 XLR connectors

     * XLR-outputs: daisy chaining of several amplifiers
