AEV DSW Dual Switch Audio Changeover Stereo audio balanced switcher

AEV DSW Dual Switch Audio Changeover

A Stereo audio balanced switcher, 2 IN /1 OUT with blank detection, XLR connectors; MPX audio switcher, BNC connector,. 2 IN /1 OUT, with blank detection, Pilot level detect, RDS signal check, logic I/O port, 19" 1U.

All level management is digitally controlled!
The application range can be either in studio or remote ( Supervisor).
Use it in the Studio for switching from a Main stereo source to a secondary source.

Use it as Supervisor for switching from a Main stereo source i.e. a satellite reception, to a secondary source such as, for example, a network of emergency terrestrial radio links, generating eventual alarms and carrying out emergency switchovers.

A Supervisor use is the ideal solution to enable, in remote sites, the management of different terrestrial transmitters chains, for example between a satellite reception and a network of terrestrial radio links, hence managing eventual alarms and carrying out emergency switchovers.

Dual Switchis very easy to program, thanks to its display and endoder located on its front panel.

Dual Switch is equipped with a passive By-pass system (Relay) capable of directly by-passing the main input (MAIN) on the output (OUT) in the instance of an extensive malfunction of the equipment or of a power loss.

Dual Switch is equipped with a color graphic display for a simply management

Dual Switch can accept external controls normally off or normally on, steady or pulse. The inputs are opto-insulated and the configuration can be carried out with its panel or with a PC.
