IT’S… An acoustic conditioning system that adjusts and enhances the acoustic characteristics of a space while preserving its natural features.
DETAILS: Following its launch at InfoComm 2012, Yamaha is now in discussions with audio consultants about bringing its latest Active Field Control system, AFC3, to the European market. The acoustic conditioning system works by creating feedback loops of microphones and speakers located in the reverberant field of the room to ‘recycle’ the reverberant energy, thus extending the reverb time. Used to create varying
reverb time settings which suit different performance applications within the same space, AFC can be used for a range of applications. One example is adding a sense of ‘spaciousness’ to under- balcony or stage areas, so that all audience members and performers can enjoy the same sense of connection to the music and a greater shared experience. AFC systems can also be used to add early reflections or as crowd enhancement systems. Yamaha’s advanced AFC3
processor supports the transfer of finite impulse response (FIR) calculations to dedicated hardware, while a new AFC-FIR processor card
can be mounted in the AFC3 processor and, in addition to handling the processor- intensive FIR calculations, provides four AES inputs for system microphone channels.
AND ALSO: AFC3 provides more than 120 times the number of FIR taps than earlier versions of AFC. This makes it possible to extend a room’s natural reverb time
IT’S… A plug connector system for four-fibre optic cables, for HD video transmission.
DETAILS: The HI-FIBER4 system consists of four standard LC fibreglass connectors, protected by a robust and compact all- metal housing. It includes a cable plug, a universal panel socket plus various adapters to other connecting systems. The socket can be used as a panel coupling, and also as a universal cable coupling for extensions or cascading purposes. It can be linked with either up to four conventional LC-Simplex connectors (or two LC- Duplex connectors or a combination of both) and also with the HI-FIBER4-MC cable plug.
The modularity of the
system makes it easy to integrate it into existing systems. It mounts directly behind front panels by using two M3 threads;

alternatively, it can be installed as a front panel installation with countersunk screws.
The cable plug can be fitted with up to four LC connectors, which are assembled and plugged into a metal cross-fixture after inserting the cable. About 50mm of cable can be stored inside the connector for possible use in future repairs.
The locking mechanism is
operated by a push-pull locking ring. The cap and a spring-loaded sleeve protect the fibre system from dirt and damage. When plugged in or with protective caps locked, IP68 protection class is achieved.
AND ALSO: The HI-FIBER4 is available from Sommer Cable, which also can supply the appropriate four-fibre cables.
