These connectors provide the balanced and unbalanced connections for the input/output card fitted in the four card
slots in a JBL Synthesis SDEC device. A green LED next to the slot assignment letter A, B, C or D indicates that an
input card is fitted and an amber LED when an output card is fitted. The analog connections are balanced/unbalanced,
on Phoenix/Combicon connectors. Depending on which model and configuration you have purchased will determine
which input/output card has been installed at the factory. Please make sure to order the correct wiring kit, either
S3000IC or S4500IC, with your system.
