1 General
The BES-0808/75 is an 8x8 AES/EBU digital audio router with unbalanced 75 Ohm in- and outputs. This
state of the art router provides high performance circuits in SMD technology for maximum system
performance. The BES-0808/75 is designed for all demanding routing tasks in digital studio and
broadcast environments. The built-in RS-232 interface allows the user to control the router via the Triton
Router Control System PC software with many operational features. The control bus allows linking the
unit to the BVS-0808 or BDS-0808 video router thus creating an 8x8 AFV router. Several units can be
combined to form a 2 or more layer AES/EBU matrix system. One or several Triton remote control
panels can control the BES-0808/75 as well. Another unique feature of the Triton 8x8 series is the
possibility to reconfigure the router via the configuration switch on the back plane so that the unit can be
several types of routers:
8x8 AES/EBU 1 Channel
4x4 AES/EBU 2 Channel
2x2 AES/EBU 4 Channel
