Audio Presence LED
The red audio presence LED indicates the presence of incoming audio on a

audio will not trigger it) and it stays illuminated for 10 seconds after the
detected audio falls below the threshold.

numeric equivalent of GL). Just turn the volume/ setup knob until 45 is shown
on the screen and then push the knob to select.

Headphone Jack
This standard 6.35mm (1/4”) stereo headphone socket accepts headphones
from 30 to 1000 Ohms.
It has a unique headphone amplifier that allows it to provide the correct output
level regardless of the headphone impedance and it can also have mono
headphone jacks connected with no adverse effect.

USB Update
The USB connector is used for connected a PC to the device for loading
software updates.

XLR. The headset connector carries both microphone in and headphone out
audio circuits.
