SDEC-4500X

BlueLink

SDEC-3000 has no BlueLink™ connections, but is otherwise identical to the SDEC-4500P and SDEC-4500X.

￿AC MAINS

AC Mains input to the universal switched-mode power supply; operates over a wide range of AC input voltages from 85V to 270V, 50/60Hz.

￿LOCATE

Pressing the Locate switch on the rear of the unit will illuminate the Locate switch on the front and identify the device within the DACS software.

￿RS-232

Serial port for connection of external calibration and configuration equipment not used at this time.

￿ETHERNET

The main connection for the proprietary system control network, and for third-party Ethernet control. The SDEC must be connected to an Ethernet hub during the calibration process.

￿BLUELINK™ 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.

￿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.

￿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.
