DST-4120 Stereo Power Amplifier with DSP is one two channel low impedance amplifier built-in DST processor Network audio, ideal for IP network multiple audio streaming professional sound system, 4 channel professional audio power amplifier, 4 channel input output, 4 IN 4 OUT DST processor, support 100V & 8 Ohm speaker connection.
Description The DST-4500 is 4-channel flexible amplifiers with DSP processor for high performance installation sound system. The 4-channel power amplifiers with DSP processor are rated power output at 4 x 120W to 4 x 500W@ 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 high performance DSP processor, which can ensure each input and output could be managed respectively. One mini USB on front panel for DSP configure.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 4-channel amplifier with DSP allows receiving and sending of low latency, high quality audio with multiple Presets.
