The HDLM 8 Loudspeaker Management Controller is capable of managing more complex sound reinforcement systems. A web browser based user interface with multi-client capability allows real time access from a PC or a Mac to user-critical parameters for multiple users simultaneously. Excellent dynamics, a low distortion factor and filters with outstanding sound properties ensure first class audio quality.
A large high-definition colour display, clearly assigned buttons for navigation and input screens, and the USB port, enable hassle-free adjustments directly on the controller. When combined with a WLAN-USB stick, all functions can be controlled with the smartphone app goHDLM. The Linux based operating system of the HDLM 8 can optionally be upgraded with a 1000 Mbit Ethernet interface.
The API (application programming interface) makes it possible for any C programmer to fully access the HDLM 8.
This allows, for example, direct control of presets, or any other control values, via a Crestron or AMX touch screen controller.
