The AD5840 provides 4 balanced
mic / line level analog inputs to the
Hydra2 network in a 2 slot-wide
module. The audio interface is via 4
female XLR connectors.
Front panel LEDs indicate audio signal
presence for each input, lighting green for
signals above -60dBFS.
Each input also has front panel LED
indicators which light red when 48 V
phantom power is on.
The standard modular I/O status LED
flashes green once the card has booted
and lights solid green once a connection
between the card and the Hydra2
interface has been established.
