DirectOut EXBOX.BLDS MADI redundancy switch
EXBOX.BLDS is a sophisticated MADI redundancy switch for production
environments with advanced reliability requirements. In addition to the
standard changeover from one input to the other in the case of a loss of
the MADI signal, the unit incorporates a unique feature from DirectOut,
the Buffer Loop Detection System™.
Enhanced Signal Control
The Buffer Loop Detection
System™ is used to detect silence or a corrupted input signal - e.g.
caused by an application hang of the playout system (repeating buffers)
or stuttered playback due to system overload.
A provided software tool creates a .wav file containing a low level
signal which is inserted into the MADI stream. The artificial design of
the Buffer Loop Detection Signal
enables reliable and inaudible switch-over within one sample.
For less critical switching requirements a simple pilot tone can also be used to trigger automatic switch-over.
The MADI input can be switched
manually by a push button on the front panel of the device. Different
redundancy modes (prioritisation of inputs) offer the means to adjust
the trigger behaviour of EXBOX.BLDS.
Four GPIs and four GPOs are accessible via
DSUB-9 connectors. The GPIs may be used to select the MADI input or to
trigger a switch-over. GPOs provide monitoring of the current input and
EXBOX.BLDS offers highest
flexibility as it provides two module based MADI ports. The customer may
choose from modules of three different interface types:
- optical SC (single-mode or multi-mode)
- coaxial (BNC)
The Small Form Factor Pluggable cage can be fitted with any SFP module suitable for the particular application.
The device can be updated with a new or customised firmware via the integral USB port.
Two robust Hirose sockets are
available to plug in up to two external power supply units or battery
packs for safe operating conditions with redundancy.
Each EXBOX can be mounted into a
standard 19’’-rack by using the optional kit BOXMOUNT.XL. Up to three
devices may fit side-by-side within 1 RU.
