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.

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.

When connecting the power supply, voltage polarity  
is extremely important. Applying power with  
incorrect voltage polarity could damage the power  
supply and the BBG 6 A. Identify the power cord
