● Description
The Extron BBG 6 A Blackburst, Color Bars, and Audio Generator offers six broadcast quality, NTSC or PAL blackburst output signals, allowing a variety of video equipment to be genlocked to a common reference signal. The blackburst signal consists of three reference signal components: vertical sync, horizontal sync, and color burst. The first two outputs can also provide broadcast quality NTSC SMPTE Color Bars or PAL full-field Color Bars test patterns via a selectable DIP switch. Additionally, the BBG 6 A comes with a 1 kHz audio generator with balanced or unbalanced audio on captive screw connectors. Part of the VersaTools® line of products, the BBG 6 A is housed in a 1U, quarter rack width metal enclosure, making it ideal for installation in small spaces or portable field use.
● Features
- Broadcast quality blackburst outputs - Six outputs on female BNC connectors for creating blackburst reference signals to feed into genlockable devices.
- Broadcast quality color bars generator - Two of the blackburst outputs also provide standard SMPTE color bars for NTSC and full-field 8-bar for PAL, selectable via DIP switch for easy troubleshooting and alignment.
- Audio test signal - Built-in audio generator offers 1 kHz, balanced/unbalanced output on captive screw connectors for simplified audio troubleshooting. The output level is switchable from +4 dBu to -10 dBV via DIP switch.
- Compact metal enclosure - 1U, quarter rack width metal enclosure.
- Versatile mounting options - Rack, under-desk, and projector-mountable.
- Power indicator - LED for easy troubleshooting.
- Power supply - External international power supply included (part# 70-055-01).
