Applications

EXBOX.BLDS can be used as a plain signal switch or
for sophisticated observation of MADI signals with
automated switch-over and revert.
Typical applications include:
• Signal distribution
• Playback applications, e.g. live performances
• Observing MADI transmission with external
reporting

How it works

One of the two MADI input signals is routed to both
MADI outputs. Depending on the settings the input
selection is triggered manually (by a push button
or by a GPI contact) or automatically (by a trigger
condition).
Trigger conditions are:
• loss of carrier (no input lock)
• loss of BLDS signal
• loss of Audio Pilote Tone
The inputs can be prioritized for revert when the
signal is regained after a loss. Additionally the
selection of an input may by forced by a GPI contact.
External control is offered by four GPIs and the
output signal state is monitored by four LEDs and
four GPOs.
