The AD500 4-channel amplifier features an on board, state-of-the-art, DSP engine that can be configured to operate as a four zone matrix system, without the need for additional equipment.

The AD500 can be accessed anytime, anywhere through Wi-Fi via a built-in Wireless-Access-Point (WAP) or through ethernet for simple connection and easy configuration.  Controlling and powering any speaker system, creating a multi-zone sound system in minutes. The easy-to-use web-based interface allows remote control of all DSP functions as well as monitoring from any PC, tablet, or smartphone, regardless of operating system. No software to install, simply connect via the Ethernet port or the built-in Wi-Fi, and you're ready to go.

Software-selectable multi-mode operation with switchable Normal Low Z (2Ω to16Ω), Bridge Low Z (4Ω to 8Ω) or Bridge Hi Z (70 V/100 V) 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, maximising the efficiency.
