Klark Teknik DM8500 - Networked Digital Audio Processor with DSP and Acoustic Echo Cancellation in Black Finish

The Klark Teknik DM8500 is a high-performance networked digital audio processor designed to meet the demanding needs of modern audio installations, offering unparalleled flexibility and powerful features for a wide range of applications. The DM8500 integrates seamlessly into corporate environments, hospitality venues, conference rooms, and more, providing the processing power and DSP capabilities necessary for complex audio systems. With 128 channels of dual-redundant Dante/AES67 audio transport, the DM8500 allows for easy integration with Dante-enabled devices and third-party systems, supporting up to 64 inputs and 64 outputs in real-time audio networking. This powerful networking capability ensures that the DM8500 can be used in large-scale installations that require extensive audio routing, providing high-performance audio with minimal latency.

The DM8500 offers a comprehensive suite of features that makes it an ideal solution for conferencing systems, meetings, and other installed audio applications. It includes 10 high-headroom analog mic/line inputs and 6 electronically balanced, low-impedance line-level outputs, providing excellent sound quality for capturing and distributing audio. With its 24 freely assignable Acoustic Echo Cancellation (AEC) channels, the DM8500 effectively handles challenging acoustic environments, such as large meeting rooms or conference centers, where reverberation and echo can interfere with speech clarity. The AEC functionality ensures that all participants in a teleconference or meeting experience clear, echo-free audio, enhancing communication and making the DM8500 an invaluable tool for modern conferencing systems.

Additionally, the DM8500 features a 16-channel ULTRANET digital audio output bus, allowing for easy integration with ULTRANET-compatible devices, such as personal monitor mixers and networked speakers. This digital audio transport technology simplifies the wiring and reduces the complexity of large audio systems, providing reliable, low-latency audio over a single CAT-5 cable. The DM8500 also includes a class-compliant USB audio connection for integration with soft codec-based conferencing systems, further enhancing its flexibility and usability in virtual meetings, live broadcasts, and other digital communication setups.

Designed around an open architecture, the DM8500 allows system integrators to easily configure the unit to meet the specific needs of their clients. The DM Designer software provides a simple, intuitive interface for configuring audio routing, DSP processing, and control, enabling users to build custom configurations tailored to their requirements. With the embedded media engine for audio playback and recording, the DM8500 can also be used for applications requiring media management, such as recording and replaying content for training, presentations, or events.

For greater control and monitoring, the DM8500 offers embedded control modules for Lab.Gruppen network amplifiers, allowing users to manage and monitor amplifier settings directly from the DM Designer software or the DM Kontrol control panel application. The device also includes six user-configurable general-purpose input/output (GPIO) connections for triggering external devices, further expanding its versatility. Additionally, the DM8500 features an embedded HTML engine that serves custom control pages to any networked device, allowing users to access and manage their system from a web browser without the need for additional apps.

Built to the highest standards, the DM8500 is engineered with an auto-ranging universal power supply that supports voltage ranges from 100 VAC to 240 VAC, ensuring reliable operation in different regions. With its compact 1U rack-mountable design, the DM8500 is an ideal choice for professional audio environments, providing all the necessary tools for controlling, routing, and processing audio with ease and precision.
