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.

Specifications:

  • Distributor Configuration:  2x8 with selectable input
  • Input Signal:
      -  SMPTE/EBU Longitudinal Time Code (Forward or reverse; play, shuttle and wind)
      -  Impedance: 20KO bal.; 10KO unbal.
      -  Level: -30dbU min; +20dbU Max
  • Output Signal:  
      -  Waveform: selectable rise time: 1µs (square wave), 25µs (SMPTE) or 50µs (EBU)
      -  Impedance: 600O bal.; 300O unbal.
      -  Level: adjustable (front panel pot): full off to +8dbU bal.; to + 2dbU unbal.
      -  Amplitude distortion: less than 2%
  • Front Panel indicators:  Signal present; Selected input Power on
  • Connectors:
      -  Time Code Inputs: XLR Female (x 2)
      -  Time Code Outputs 1- 8: DB-25 F (x 1)
      -  Power: 4 pin circular (x 2)
  • Power:  
      -  12VDC @ 1.3A
      -  Redundancy: two separate supplies can be connected to the 2 separate power inputs. If one supply fails, the other takes over and an error is reported. The faulty supply can be swapped without having to power down.
  • Dimensions:  19” x 8.125” x 1.75” (48.26 cm x 20.64 cm x 4.45cm)
