￿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.

PHANTOM

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

￿USB

This is currently for future use and is not supported.

￿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 USB, serial or control ports.

￿NETWORK LINK

The Network Link indicates the presence of Cat. 5 Ethernet cables. If no cables are connected, the LED is unlit;

the LED flashes if either a control or CobraNet® cable is fitted, and remains illuminated if both cables are connected. The network link is used for configuring and calibrating the Synthesis System when using the DACS calibration, and for system status when using the SDEC-4000.

￿LCD (LIQUID CRYSTAL DISPLAY)

Indicates the name/ID and IP address of the unit.

￿CONTRAST (HOLD)

Pressing and holding the Locate 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 and identify the device within the DACS software.
