Product Description

The MRBX-L-X400-C provides a comprehensive audio solution for large meeting rooms accommodating up to 18 people, with everything needed to outfit a conference room for seamless communication. The TesiraFORTÉ X 400 consolidates audio processing and network connectivity into a single device to streamline the rack and the room.

Award-winning Parlé microphones use Beamtracking® technology to latch onto talkers, so participants can move freely around the room and remain easily heard. This is an electronics-only bundle (no loudspeakers); pair it with Desono ceiling loudspeakers or your preferred commercial speakers. Pre-terminated, plenum-rated Cat 5e cabling and configuration-free networking get meeting spaces up and running in roughly half the time of competing systems, while automated tuning keeps every room deployment consistent.
