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.
Installation
The BBG 6 A can be mounted on a rack shelf (VersaTools or
universal), under a desk or tabletop, or on a projector bracket.
Rack mounting
For optional rack mounting, mount the BBG 6 A on a VersaTools
19" 1U Rack Shelf (Extron part #60-190-20 or #60-604-20)
(figure 1) or a standard Universal 1U Rack Shelf (part #60-190-01
or 60-604-01) (figure 2). On the standard rack shelf, the BBG 6 A
mounts in one of four locations to the rear of the rack or in one
of four locations to the front of the rack.

4.
For furniture mounting, drill 3/32" (2 mm) diameter pilot
holes, 1/4" (6.3 mm) deep in the mounting surface at the
marked screw locations.
DIP switch — Use these DIP switches to select between +4 dBu
(pro) or -10 dBV (consumer) audio output level, between NTSC
or PAL (USA only) output, and between blackburst or color bars
for outputs 1 and 2.

5.
For furniture mounting, insert #8 wood screws into the
four pilot holes. Tighten each screw into the mounting
surface until just less than 1/4" (6.3 mm) of the screw head
protrudes.
With the first DIP switch set to “+4,” the unit outputs
+4 dBu audio level with balanced wiring. With the DIP
switch set to “-10,” the unit outputs -10 dBV audio level
with unbalanced wiring.

Connections, Indicators, and Controls
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
Audio output connector — Insert a 3.5 mm, 5-pole captive
screw connector into this connector for a balanced or
unbalanced 1 kHz sine wave audio tone.
e
As an alternative, you can use an Extron P/S 100 Universal
12 VDC Power Supply (part #60-357-01), which can power up to
ten BBG 6 As or other Extron 12 VDC devices using only one AC
power connector.
Do not tin the stripped power supply leads before
installing the captive screw connector. Tinned wires are
not as secure in the captive screw connectors and could
pull out.
N
