Card with 2 independent audio inputs.
Occupies slot 2 in the COMPACT. Additional UMX-EA3 cards may be inserted in
slots 3 to 10.
Each input may be configured as a music input or as a paging input. The inputs
configured as paging incorporate a talk priority usage. This priority may be
activated through a contact or may be voice activated (VOX control).
Input A has two types of connectors: RJ45 and XLR. Input B only has connector
RJ45.
The sensitivity of the input may be modified via the configuration software: AUX H
(0 dB), AUX L (-20 dB), MIC (-60 dB) or MIC (-60 dB with speak filter). Also, each
input has a potentiometer with fine adjust of the sensitivity.

When ordered, cards may be supplied with inputs balanced using a transformer
