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™ (BLDS™).
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.
Input Switching
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 behavior of EXBOX.BLDS.
