M804DSP: 4 channel, 3000w, DSP and Webinterface


The M804DSP is a smart full matrix DSP Class D 4-channel amplifier that delivers flexible reliable power output of 4 x 750W in a full rack 2U format, driving both conventional low impedance (2Ω to 16Ω) loudspeakers and high impedance (70V/100V) transformer coupled loudspeakers or any mix of the two. The on board, state-of-the-art, full matrix, DSP engine can be configured to suit a wide range of tasks, without the need for additional equipment, to drive a wide range of loudspeaker systems. Everything you need is right there. The close integration of processing and amplification allows the DSP to monitor and better adapt to amplifier behavior, making dynamics processing far more accurate and effective than that typically achieved with separate components. The active PFC (Power Factor Correction) power supply technology enables universal AC mains operation and delivers consistent, regulated power worldwide.

The M804DSP can be accessed anytime, anywhere through Wi-Fi via a built-in Wireless-Access-Point (WAP) or through ethernet for simple connection easy configuration, controlling and powering any speaker system, creating the most impressive multi-zone sound system in minutes. The easy-to-use web-based interface allows remote control of all DSP functions as well as monitoring of all amplifier vital functions from any PC, tablet, or smartphone, regardless of operating system. No software to install (it’s built into the M804DSP). Simply connect via the Ethernet port or the built-in Wi-Fi, and you're ready to go.

Power sharing / Digital Inputs / GPIO pins for control !

Software-selectable multi-mode operation with switchable Normal Low Z (2Ω to16Ω), Bridge Low Z (4Ω to 8Ω) or Bridge Hi Z (70V/100V) allows you to mix and match speaker types as needed. Power Sharing technology distributes dynamically the available power between each amplifier channel pair, so that it can be used where it is needed the most, maximizing the efficiency and the dynamic of the system.
The SPDIF Digital I/O can connect to other compatible equipment or bridge two M804DSP amplifiers to digitally expand the system.
Five programmable GPIO pins are provided as additional control lines. These pins can be programmed to remotely control the volume levels for each Zone by means of external remote potentiometers. Power On/Off, Standby and Mute are also remotely controllable via GPIO.
