PBS03 - Dual channel relay based back-up switcher with signal integrity checking

Description

The PBS03 is a dual channel digital SD-SDI change-over back-up switch with integrity checking. The PBS03 has 2 SDI inputs to 2 outputs. The loop-through input is high impedance and must be terminated in 75 Ohms when not used. The cross-switching can be executed by several signal analysis triggers. These triggers are loss of input, loss of embedded audio, freeze frame, TRS errors or any combination of these.

Features

• Electromechanical Relay based switching on connector panel for optimal reliability (even when the probing card is removed)
• 2 SDI inputs
• 2 SDI outputs
• Switching triggers based on:
  • GPI
  • Carrier loss
  • TRS error
  • Audio silence
  • Freeze detection
  • Event (an event triggered by a different card in the same frame)
• Automatic switching (with control of back-up channel)
• Freeze length and threshold adjustments
• Silence time and threshold adjustment
• 8 fully wired alternated relay based switches (suitable for AES/EBU and analog audio)
• Cable length up to 100 meter
• Automatic (signal quality controlled) switching
• GPI based switching
• Manual overwrite on front panel switch
• Channel ‘OK’ indication by GPI output
• Full control and status monitoring through the front panel of the SFR04/SFR08/SFR18 frame and the Ethernet port (ACP)
