Main / Changeovers (video, audio, SDI) / PRB-098

PRB-098 series audio bypass relay modules protect any part of analog audio or balanced AES infrastructure by means of switching from a MAIN to a STAND-BY line.

Each module supports two independent channels with local (from a frontal panel) and remote (by GPI commands) control. Automatic by-pass is provided in case of power down condition.

PRB-098 module fits into a 1U rack via the PM-021 rack mounting plate.
