BBG 6 A • Introduction 
Introduction
The BBG 6 A and BBG 6 A J (an exclusively Japanese model) are
compact, high performance blackburst, color bars, and audio
generators. Unless otherwise noted, the name BBG 6 A refers
to both the standard (USA and European countries) and the
Japanese models within this guide.
The BBG 6 A provides six broadcast quality blackburst signal
outputs on BNC connectors, two of which can be changed to
color bars with a DIP switch. For the standard BBG 6 A, the user
can select output signals as either NTSC or PAL.
The BBG 6 A J outputs NTSC only and has no setup pedestal in
its video output. Color bars are standard SMPTE bars (NTSC)
or full field (PAL). The audio generator provides a single 1
kHz sine wave audio tone, either balanced or unbalanced,
with a selectable output level of either +4 dBu (pro) or -10 dBV
(consumer).
The BBG 6 A is a member of the VersaTools
® line of basic
distribution amplifiers, switchers, and video accessories. The
unit ships with an external, desktop 12 V power supply, which
accepts 100-240 VAC input.
Models
There are two available models of the BBG 6 A:
BBG 6 A (NTSC and PAL signal)
— Handles NTSC and
PAL signals. This version is used in the USA and some other
countries.
BBG 6 A J (NTSC signal only)
— Handles NTSC signals only.
This version is used in Japan.
Other than their differing signal options, these two models are
identical.

The BBG 6 A can be mounted on a rack shelf (VersaTools or
universal), under a desk or tabletop, or on a projector bracket.
