The INTUGRID HMA74 is a core unit for Intusonic's digitally controlled audio zoning, which is complemented by the HZE11 zone remote wall panel. Together they deliver a scalable audio routing system for background music. The HMA74 offers two microphone inputs, 5 line inputs, a front-panel 3.5mm TRS input and a LINKOUSTIC 4.2 wireless audio link, which can be flexibly routed to its 4 output zones, with each of these zones controllable either by the on-board user interface, the included IR remote or a wall remote control panel. Every zone can be configured extensively to meet the application's demands, while keeping user interaction extremely simple. The HZE11 zone remote wall panel allows to remotely control all zone settings plus accepts a local audio feed.
