8 LED INDICATORS

8.1 Ethernet

The LEDs on the Ethernet connector indicate the Ethernet connection and activity status.

Left Link LED Status Right Activity LED Status

Amber color 10 Mbps Amber color Half duplex

Green color 100 Mbps Green color Full duplex

On Link established On/flashing Data activity

Off No link Off No activity

8.2 U-Net Indicators

The U-Net LEDs on the front/rear panels indicate the U-Net network status.

Green LED (

) Red/Yellow LEDs (!) Status

On Off U-Net network detected

On Flashing Local fault: not sending or receiving on the assigned

U-Net channel(s) or local and received sample rates are

not synchronized

On On (2 seconds) Local fault detected on another device on the network

Off Off No network detected

8.3 Input meters

The input meters indicate the signal level in dB below 0 dBFS (0 dB Full Scale), the clip level of the ADC

(analog to digital converter). An input meter still functions when its Input Channel is muted. Ideally, the

highest levels of the signal should illuminate the -6 LED segment, but not the CLIP segment. Occasional

flashing of the CLIP segment may be sonically acceptable.

LED Segment Signal Level

Clip Red 0 dBFS

- 6 Yellow -6 dBFS

-12 Green -12 dBFS

Sig Green -40 dBFS

8.4 Output Meters

Unlike the input meters, the four LED segments of each output meter make up two different meters.

8.4.1 SIG, -12, AND CLIP SIG SEGMENTS

These three segments monitor the signal level in dB below 0 dBFS (0 dB Full Scale), the clip level of the

DAC (digital to analog converter). An output meter still functions when its Output Channel is muted.

Ideally, you want the highest level to illuminate the -12 segment, but not the CLIP segment. You can set

levels lower than this, but understand that you are reducing the signal-to-noise ratio.

LED Segment Signal Level

Clip Red 0 dBFS

-12 Green -12 dBFS

Sig Green -40 dBFS

8.4.2 LIM SEGMENT

This segment monitors the limiter status referenced to the level set for the limiter threshold. The Lim

segment will indicate limiting even when its Output Channel is muted.

LED Segment

Status

Lim Yellow On when the limiter threshold is exceeded and there is gain reduction

Occasional flashing is OK. However, if the LED is rapidly flashing yellow or is on steadily a large

percentage of the time, the input signal to the loudspeaker may be exceeding the loudspeaker’s capability

and the volume level should be reduced.
