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 switching state.
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.
