Product Overview
The SR-28 is a simple and elegant solution for time code distribution. Housed in a single U 19” chassis, it provides 8 outputs and 2 inputs. The level of each output is individually adjustable via front panel pots. The input is selected via a front panel switch.A remote selector can also be used. In addition, the SR-28 reshapes time code while distributing it, eliminating amplitude distortions and level fluctuations.
Features:
- Buffered Outputs: Multing a single time code source to multiple destination can cause many problems. The SR-28 eliminates those by distributing time code through balanced and buffered outputs.
- Reshaping: The Brainstorm Time Code Distributors are more than audio DA’s: they reshape the signal before distributing it. Audio DA’s on the other hand, transfer all distortions and level fluctuations present at the source.
- Low Input Threshold: The SR-28 recognizes time code at levels much lower than the threshold of many readers (better than -30db) while still safely above the noise floor. This feature makes it often possible to recover unreadable code by reshaping it, almost as if it was regenerating over drop outs.
- Output Level Adjust: Output levels are adjustable individually via front panel pots from full off to +12db. These adjusted levels remain constant regardless of input level fluctuations.
- Switchable Rise Times: The output rise time (slew limiting) is switchable between 25µs (SMPTE), 50µs (EBU) and 1µs (square wave, preferred by most readers).
- Cleaning Up Unreadable Time Code: By eliminating amplitude distortions and level fluctuations the SR-28 can often recover unreadable code.
- Dual Redundant Power Supply: The SR-28 provides 2 power inputs and an automatic switch over in case of failure.
- Sound Reinforcement: The SR-28 can drive time code over long cables making it ideal for synchronization during live shows and remote recording.
