ITEL DXVR 4

Digital Audio Changeover 4 Input

The ITEL DXVR 4 is a digital audio changeover silence detection and automatic switcher for L/R balanced analog, digital AES-EBU, MPX and IP-Streaming-USB audio sources.

The MPX signal is decoded into L/R channels by a DSP-based stereo decoder, which also provide stereo and RDS subcarriers level metering. The MPX source is considered valid only if the PI code matches with the one stored internally.

The user can determine the switching priority of the various sources and the switching timings and thresholds, using the front panel display or with dedicated software.

The unit can operate in fully automatic mode, using timings and thresholds set by the user, or it can be controlled remotely by a PC-based software, through UDP/TCP-IP/RS232.

This unit includes a passive emergency bypass, so that any input will be bypassed on its respective output, in case of hardware or software failure.

Option: MPX Decoder

Precise and reliable stereo and RDS subcarriers metering, peak modulation readout and 19 KHz subcarrier frequency error. The incoming PI is always under control, so the MPX input source can be excluded if the PI code does not match the one stored internally.
