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
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.
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.
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 (
/square wave).
EBU
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.

    During a drop out, the SR-3 generates code at the same rate ever the source time code is synchronous with video, you it did just prior to the drop out. After the drop out, the SR-3 should feed the video reference into the SR-3 and activate slowly resyncs to the incoming code.

When “Video Sync” is on, the SR-3 locks the regenerated Output Waveform code to the incoming video reference. This is recommended since video is a very stable reference.
