TRANSFORMERS

Line/splitter transformers
These line/splitter transformers made in Germany are especially manufactured for SOMMER CABLE and stand out with linearity, low vibration, and low resistance values. The casings are suitable for print assembly, are Mu-metal shielded, and provide optimum protection against interference signals. Along with the SOMMER-transmitters we have a suitable individual printed circuit board available for do-it-yourself installation. This printed circuit board is designed for SPLIT 1:1, and SPLIT 1:1+1 for use with NEUTRIK NC3FDH. This enables flexible implementation of compact single channel units, from one-channel-separator solution all the way to multi-channel-splitter system.
For especially difficult and high quality applications we now offer a transformer made by the Swedish manufacturer LUNDAHL. Model LL1570 is primarily used for the SYSBOXX (see SYSBOXX pages). This transformer fulfills all the requirements set forth in the Broadcasting Guidelines, making it perfectly suitable for even the highest demands.

Assignment SPLIT 1:1
I/P + - = DIR-OUT ground/+/-
O/P1 + - = ISO-OUT ground/n.c./-
O/P2 + - = /n.c./+/n.c.

Assignment SPLIT 1:1+1
I/P + - = DIR-OUT ground/+/-
O/P1 + - = ISO-OUT 1 ground/+/-
O/P2 + - = ISO-OUT 2 ground/+/-


n.c. = not connected
DIR-OUT = input or FOH-output, tap BEFORE transformer
ISO-OUT = isolated output, tap AFTER transformer
