TIMECODE DISTRIBUTOR / RESHAPER
SR-28 Timecode Distributor/Reshaper
For Live, Studio and Video Shoot Dates
Cleans up timcode and distributes it to multiple destinations through 8 individually buffered outputs. Ideal for long cable runs. Either of the 2 inputs can be selected.
Like it’s big brother the SR-112 Distripalyzer, the SR-28 can drive timecode over long cables, making it ideal for synchronization during live shows and remote recording.
- 2 x 8 time code distributor
- Designed to send TC over long cables
- Buffered outputs; balanced or unbalanced
- Individual output level adjust
- Low input threshold can help recover unreadable code
- Reshaper eliminates amplitude distortions and level fluctuations
- 2 power inputs for redundancy
Like it’s big brother the SR-112 Distripalyzer, the SR-28 can drive time code over long cables, making it ideal for synchronization during live shows and remote recording.
The SR-28 time code distributor, with two inputs and eight outputs, reshapes time code while distributing it, eliminating amplitude distortions and level fluctuations. The level of each output is individually adjustable via front panel pots. The input is selected via a front panel switch. Also included are 2 power inputs and an automatic switch over in case of failure.

Impedance: 600Ω bal.; 300Ω unbal.
Level: adjustable: full off to +8dbU bal.; to + 2dbU unbal.
Amplitude distortion: less than 2%
|Front Panel Indicators:||Signal present; Selected input
|Connectors:||Timecode Inputs: XLR Female (x 2)
Timecode 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.

Manual & Data Sheet
Engineering Notes / Modifications
Is the SR-28 distributor the same as an audio DA?
No. An audio DA is designed to distributes an audio signal. The SR-28 on the other hand not only distributes time code, but also reshapes it, eliminating distortions and amplitude fluctuations. Also, an audio DA may not be designed to handle a 2.4KHz square wave and may induce distortions.
How do I connect the time code outputs?
The SR-28 uses a DB25 connector with the same pin configuration as Tascam/Avid. Standard DB25 to XLR breakout cables are readily available and can be ordered from Brainstorm Electronics.
What if I need more than 8 outputs?
Multiple SR-28 units can be used in cascade. In that case, we recommend setting the rise time of the output(s) feeding the cascaded unit(s) to 1μs (square wave).No. An audio DA is designed to distribute an audio signal. The SR-112 on the other hand not only distributes time code, but also reshapes it, eliminating distortions and amplitude fluctuations. Also, an audio DA may no be designed to handle a 2.4KHz square wave and may induce distortions.
Can I switch input remotely?
Yes, an external switch can be used to change the SR-28 input selection. On the mother board, 2 pads are labeled ‘External Switch Connection’. A momentary SPST switch can be connected to those pads. The front panel LED always indicates the currently selected input. For detailed instructions, download here.
