Modern installed audio applications require a flexible digital audio processor with user-friendly features, such as user-configurable DSP and routing options, multiple inputs and outputs – and built in audio networking. Designed for installed use in corporate environments, hospitality venues and more, the DM8500 provides 128 channels of Dante digital audio networking for easy integration with other equipment. The highly versatile DM8500 seamlessly integrates with computer based conferencing systems using embedded USB, and can control and monitor external devices using built-in Ethernet and RS232 ports.
At the heart of the DM8500 is an advanced digital audio processor, with the power and versatility to handle even the most challenging application. Designed around an open architecture format, system integrators can easily configure the DM8500 to meet the requirements of any customer – and create systems that are eminently expandable, and virtually future-proof.
