Rabbit

Rabbit is an audio switcher equipped with two inlets and one outlet, available in two versions, STEREO (Left and Right) and MPX (composite)
The application range for the STEREO model can be : in STUDIO and inREMOTE ( Supervisor).

Category: Audio Switcher

– Use it in the STUDIO version for switching from a main stereo source ( MAIN Left+Right), to a secondary source ( IN Left+Right).
– Use it in the SUPERVISOR version for switching from a main stereo source ( MAIN Left+Right), i.e. a satellite reception, to a secondary source ( IN Left+Right), such as, for example, a network of emergency terrestrial radio links, generating eventual alarms and carrying out emergency switchovers.

The application range for the MPX model can also be : in Studio and in REMOTE (SUPERVISOR).
– For managing a switchover from a main MPX source, such as, for example, a network (MAIN MPX) to a local splitting area (mono IN MPX or IN Left+Right with the generation of 19KHz stereo subcarrier and RDS injection by using the signal present in the MAIN input).
– 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.

Rabbit is very easy to program, thanks to its display and keyboard located on its front panel.

Rabbit can also be programmed with an external Software via RS232 or USB.

Rabbit 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
(when the option Back-up is not present).

Rabbit is equipped with a stereo auxiliary output, on pin connectors, to enable an eventual connection to recording apparatuses.

Rabbit 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.

Rabbit supplies an opto-insulated output control which relays the status of the internal audio switcher. The status of the output opto-coupler can be programmed via panel or PC, it can be normally on, off, steady or pulse.
