￿INPUT/OUTPUT CARD MONITORING

Each channel has three LED indicators showing:

CLIP

Illuminated – Indicates clipping in the analog domain for each channel of the fitted input or output card. The LED will light at +18.5dB.

SIGNAL

Illuminated – The signal LED will light for each channel of a fitted input or output card when the signal reaches or exceeds the signal threshold of – 20dB.

SYNC/48V

This feature is currently not supported by JBL Synthesis (lights to indicate that + 48V “phantom” power has been activated for the relevant channel of a fitted input card or that Digital Sync is valid).

￿USB PORT

This is currently for future use and is not supported (SDEC 4500 does not include USB).

￿DATA ACTIVITY

The data activity LED will flash to indicate that the device is communicating with another control device, either on the network or via the serial or control ports.

￿NETWORK LINK

The network link LED indicates the presence of Ethernet cables. If no cables are connected, the LED is unlit. The network link is used for configuring and calibrating the Synthesis system when using the DACS calibration.

￿LCD (LIQUID CRYSTAL DISPLAY)

The LCD indicates the name/ID and IP address of the unit.

￿HOLD

Pressing and holding the Hold switch will cycle the LCD through its contrast range.

￿LOCATE

Pressing the Locate switch on the front of the unit will illuminate the Locate switch on the rear.
