Front Panel Indicators

Primary PSU (A)

Green LED. Illuminates when an AC input is applied and all DC outputs are present.

Secondary PSU (B)

Green LED. Illuminates when an AC input is applied and all DC outputs are present.

Primary Network

Green LED. Indicates that a network connection is present on primary port when in redundant mode. When in Switched mode, a valid network connection at either Primary or Secondary network port will cause this LED to illuminate.

Secondary Network

Green LED. Indicates that a network connection is present on secondary port when in redundant mode. Not used in switched mode.

Network Locked

Green LED. When unit is network slave, shows valid network lock. When unit is network master, shows lock to internal clock.

Sample Rate

Orange LED for each: 44.1 kHz, 48 kHz, x2, x4.

Pull Up/Down

Orange LED. Indicates that the unit is set to operate on a Dante pull up/down domain.

Channel Signal Level

8 Input and 8 Output tri-state signal level LEDs: Green LED (> -42dB), Orange LED (> -6dB) and Red (> 0dB)

AES/EBU signal indicators

2 I/O signal indicator LEDs (one input, one output). Green LED illuminates >-127dBFS

Clock Source

Orange LED for each: Internal, Word Clock and DARS

Network Modes

Redundant

Allows unit to connect to two independent networks.

Switched

Connects both ports to integrated network switch allowing daisy-chaining of devices.
