BEL 6000S
Introduction
The Bel Òlay-offÓ recorder or ÒBel BoxÓ as it is known throughout the broadcast
industry, has become the industry standard for audio Òlay-offÓ operations in VT editing. The
initial idea for the Bel 6000 came from Jeff Baker of the BBC during the AES Convention in
Hamburg back in 1989. It was a ÒwouldnÕt it be great if...Ó kind of idea, but this was enough
for Doug Russell and Mick Barnard of Bel Digital Audio to begin development. The BBC
received their prototype unit soon after, and the first production units were delivered in
January 1990.
The primary reason for the immediate acceptance of the Bel 6000 by the broadcast
industry, and the considerable numbers now in daily use, is simple - the unit is so fast and
easy to use that is saves time and hence costs.
An easy way of understanding the operation of the Bel 6000 is to think of it as a 3
track tape recorder such as the Nagra T (which it has largely replaced as a Òlay-offÓ recorder
in VT editing) which records audio signals in solid-state memory rather than tape, with two
tracks for audio and the third for timecode.
The Bel 6110 is the latest CE marked version of the widely used ÒBel BoxÓ.
The principle of laying-off audio with the Bel 6110 is similar to that of a conventional
tape recorder, but there are many advantages. For example:-
¥ 16 bit digital audio ensuring little or no degradation of sound quality
¥ AES/EBU standard digital format I/O with video, AES/EBU or word clock
reference
¥ Simple two-button remote operation or external automatic editor control
¥ Instant timecode lock
¥ Constant updating of recording last
n
seconds of programme always available
¥ No moving parts to clean or replace
¥ No tapes to purchase, load or rewind
¥ No inertia instant start/stop/lock
¥ No generation loss
¥ Small physical size standard 1U rack-mounting case with multifunction display
