The AVS-8764 provides convenient and economical solution for systems that require switching of up to 4 input AES audio signals or analog video sources, to 1 or 2 outputs. It can be configured as pair of independent 2x1 switches or as pair of 4x1 switches with common inputs. AVS-8764 accepts analog video or AES/EBU audio with option of unbalanced 75 ohms or balanced 110 ohms. All switches are performed in the vertical interval, timed to an external reference. Each switch can be controlled locally at card-edge, by an optional RCM-8120 control module, or by GPI. DashBoard and optionally SNMP monitoring is provided for input presence, reference present and output status. AVS-8764 can be combined, on a common control system, with DSS-8224 to perform multi-level, analog video, AES audio, and HD/SD SDI switching.
