Extron electronics BBG 6 A J, User Manual

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 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.
