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 #60-190-20or #60-604-20)

(figure 1) or a standard Universal 1U Rack Shelf (part #60-190-01or 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.
