Description
FOUR CHANNEL POWER AMPLIFIER WITH DSP & DANTE
DSP-4400 DSP-4300 DSP-4200
Description
The DSP-4400 is four channel Class-D power amplifiers with DSP & Dante network module for affordable audio amplification in both fixed and commercial audio installations. The DSP power amplifiers are rated power output at 4 x 400W @ 8 Ohm which provide an enormous flexibility for different size sound system applications. The DSP processor in combination with remote management software gives user friendly experience with intuitive functions overview for easy configuration. Acoustics can be optimized using noise gate, matrix mixer, PEQ, crossover, delay, compressor, Butterworth, Bessel, Linkwitz6~24. These settings can be custom configured using the English remote software by mini USB port on front panel. Loudspeaker protection is provided by an output power limiter whereby the maximum output power for every channel (in Watt) can be configured. Configuration is made simple with loudspeaker presets and full system configurations which can be selected from a library and uploaded to the amplifier. This ensures the best acoustical performance with a bullet-proof loudspeaker protection. The amplifier built-in 4 Input 4 Outputs DSP and 2 In 2 Out Dante network card, which can ensure each input and output could be managed respectively, one RJ45 port is used for & Dante and one mini USB on front panel for DSP configure. There are four balanced line inputs by XLR. The amplifiers support 100V & 8 Ohm both commercial audio & professional audio applications, where an output selector could enable this function for dedicated sound system. The installation of this Dante network amplifier with DSP allows receiving and sending of low latency, high quality audio over a standard Ethernet network.
