Page 18 Other Brainstorm Products SR-15+ Time Code Distripalyzer Combines 3 units in a single space 19” chassis: a time code analyzer, a 1x5 Time code distributor (w/reshaping on all 5 outputs) and a pilot tone stripper. The analyzer identifies time code format, detects errors and monitors video sync and color field alignment. A comprehensive report can be sent to a printer or computer via the parallel and RS-232 ports. SA-1 Time Code Analyzer SR-3 Same analyzer as the one found in the SR-15+, in a small portable package (same as the SR-3). It operates on an external 6VDC sup- ply and can be used with a battery pack. TIME CODE REPAIR KIT SR-26 Dual Time Code Distributor / Reshaper Cleans up time code and distributes it through 6 individually buffered outputs. Can be used as 2 separate units: 1x4 (master) + 1x2 (slave) or as a single 1x6 unit - Same reshaping circuitry as the SR-1 with individual output level controls & switchable output rise times. Operation Manual SR-1 Time Code Reshaper Cleans up unreadable code by eliminating distortions and level fluc- tuations. Low input threshold (better than -30db) - Reshapes in fast forward and rewind modes - Balanced or unbalanced input and output - Adjustable output level - Switchable output rise time (SMPTE/ EBU/square wave). SR-2 Frame rate counter Same unit as the SR-1 with a 4 digit counter that reads the incoming time codeʼs frame rate. Ideal to identify the codeʼs format and verify itʼs stability - Very accurate counter (4 updates per second) also shows potential problems such as wow and flutter or jitter. TB-4 Communicator System (wireless talkback remote) A high-performance infrared remote that allows the producer to acti- vate the consoleʼs talkback from anywhere in the control room - 4 switchable talkback functions - Rechargeable transmitter - No aim- ing necessary - Easy to install - Includes transmitter and receiver.
