Klark Teknik DM8500Ā Overview

TheĀ Klark Teknik DM8500Ā is an advanced digital audio processor for installation applications and is equipped with user-friendly features such as DSP and routing options, auto mixing, and multiple inputs and outputs including 64 x 64 channel Dante and 16 channels of ULTRANET audio outputs.

Designed for installation in boardrooms, council chambers, courtrooms, and more, the DM8500 provides 24 channels of wide-band Acoustic Echo Cancellation (AEC), effectively removing secondary room reflections from the signal path. It seamlessly integrates with computer-based conferencing systems and audio networks via USB, and can be remotely controlled using the built-in Ethernet and RS-232 ports.
