The SR03-04 Distribution Unit is intended to be used with the SR03-01Mk2 Universal STEP / SYNCHRO Converter.
The STEP or SYNCHRO signals from SR03-01Mk2 is distributed to six (6) mechanical repeaters – each with a block of FUSES.
S1, S2, S3 Ref 1 & Ref 2 are all fused with 2.5A /250V AC SLOW-BLOW fuses.
If you need to feed more than Six Repeaters it is possible add another SR03-04 unit and Daisy-Chain it to the first SR03-04 unit
