Description
INTEGRATED WEB INTERFACE
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.
DSP PROCESSING
The integrated web interface controls a powerful signal processing engine extending the level of functionality. The state-of-the-art full matrix Digital Signal Processing (DSP) can be configured to suit a wide range of tasks, without the need for additional equipment.
From processing input sources, managing up to 4 zones, correcting up to 4 independent rooms, to fine-tuning 4 speaker outputs, all the powerful state-of -the-art processing tools you need are there.
OUTPUTS
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.
DIGITAL
The SPDIF Digital I/O can connect to other compatible equipment or bridge two M804DSP amplifiers to digitally expand the system.
GPIO
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.
