Leading Belgian broadcaster VMMa has installed nine Bel Digital Audio 7150 digital audio synchronisation delays in its line centre to sync the audio from ISDN codecs with incoming images.
‘It’s all about antenna material and not only about monitoring,’ says Chris Wolters at VMMa. ‘We bought this model because it can be set to deliver long delays and has a choice of presets for different delay lengths. The 7150 also provides both AES and analogue outputs and it is very simple and intuitive to use. The combination of these features plus the hard bypass and the fact we did not need any other effects, just a high-quality versatile delay, made the Bel delays the obvious choice for us.’
VMMa operates six TV channels in Belgium including 2BE, VTM the first commercial Flemish language station, JIM targeting the younger market with music and youth oriented output. They also operate several radio stations including Q Music and Joe FM.
The Bel 7150 is a digital audio delay featuring both analogue and AES connectivity as standard. The unit can delay stereo audio by up to 10.4s [260 frames PAL, 312 frames NTSC]. Eight user-defined settings may be stored in memory and recalled locally or remotely via GPI’s. The delay time may be changed in increments of samples, milliseconds, fields and frames. Field and frame values may be changed to reflect PAL or NTSC operation, whilst a front panel lock is provided to prevent inadvertent operation and bypass is engaged in the event of power failure.
It provides simultaneous analogue and AES outputs. This facility allows the 7150 to also function as an analogue to digital or digital to analogue converter. The AES output can be synchronised to an external AES reference input. A bit accurate mode is provided that allows AC3 and Dolby E to be delayed. The unit is particularly suited to video/audio resynchronisation (lip sync), audio web streaming and digital broadcast synchronisation where a very fine delay adjustment is essential.
The 7150 delays were supplied via Apex Audio.
