The 1U central controller and DSP for wired Bronx dialogue systems. One CAT5e cable carries up to 64 audio channels, the platform expands to 5200 discussion units, and a built-in DANTE module, 4-zone output and PELCO / VISCA camera tracking make it the brain of the conference room.
Specifications as per the official Bronx datasheet (2026, Rev. A). Specifications may change without prior notice.
The heart of the wired conference room. A single CAT5e cable transmits up to 64 channels of full-digital audio over the hand-in-hand ring network, the platform scales to 5200 discussion units, and on-board DSP delivers 16-segment EQ, AGC, AFC, auto-mix and four-zone separated output — with USB recording, DANTE and PELCO / VISCA camera tracking.
Bronx Dialogue Software adds digital discussion and meeting management: role control for chairperson, delegate and observer, reusable meeting templates, room-layout unit management, request-list management, integrated electronic voting with real-time results, and name display per the seating plan.
