Feature highlight video: HDL410 unified coverage map

Traditional multicomponent audio systems were once the only way to get pro AV performance in your extra-large spaces. But that was before. Now our HDL410 system — part of our pro series — delivers the high-quality audio you need in an easy plug and play solution that can be installed in less than 60 minutes.

Our unified coverage map is part of how we make this possible. It represents a radically different approach to audio by enabling the physical mics from two microphone and speaker bars to be processed together instead of separately. The result is clearer, more consistent audio in spaces up to 35' x 55' (10.7 x 16.8 m).

Here’s James Rempel, our director, product management, to tell you more.

Exclusive to the HDL410 system is the unified coverage map. This innovative feature represents an entirely new way of processing audio from multiple microphone arrays in a room. It’s really the secret to making audio conferencing in large spaces as simple and effective as it can be today in smaller spaces.

Here’s how it works. With traditional audio systems, each microphone component — such as a ceiling tile — is processed separately and then everything gets mixed together in a DSP.

Our unified coverage map takes a fundamentally different approach. It processes the physical microphones from the two bars together to create a giant microphone array with an aperture that spans the entire room.

Each virtual mic can be targeted with greater resolution and precision. And the system operates as one microphone so there’s no mixing or switching artifacts. This feature makes it possible to cover larger spaces — up to 35 feet by 55 feet — with a minimal number of components.

With the unified coverage map, remote participants can hear clear consistent audio from everyone in the room even if they’re moving — because there are no handoffs between microphone devices or zones. It also delivers increased processing gain and greater consistency of gain across a large area. Plus, there’s a lot more flexibility in where you can mount the HDL410 microphone and speaker bars
and a lot fewer components to deal with.

It all adds up to a solution that delivers a much better audio conferencing experience for remote participants and a system that’s easier to install and easier to manage.
