CONNECTORS (SDEC-4500 ONLY)
The SDEC-4500P and SDEC-4500X use BlueLink to send and receive audio data.
Please Note: When using the SDEC-4500, you must connect the two units through the BlueLink connection, using
a Cat. 5e patch cable.
C CONTROL INPUTS
The SDEC-4500 can be configured for full-range or bi-amp operation by using these control inputs. The SDEC-3000
does not need or use this connection.
D INPUT/OUTPUT CARD POSITIONS A, B, C AND D
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.
