I/O Connections
All audio input and output, control, Ethernet, and AC power connections are
made via various connectors mounted on the AM-10HD’s rear panel.
Nine XLR connectors are provided for analog and digital audio input and output
connections.
An RJ-45 connector is provided for Ethernet connection.
Two DB-9 connectors provide 8 GPI inputs (for selecting the first 8 presets) and
4 GPO outputs.
The pinout drawings on pages 1-14 through 1-16 summarize all wiring connec-
tions.
Audio Inputs
Input audio can be applied to either the analog left/right inputs or to an AES3 digital
input. The AES3 input accepts sample rates between 32 kHz and 96 kHz.
Automatic audio failover from one input to the other is a user selectable option.
Failover from AES3 to analog is instantaneous and based on invalid or missing bits
in the AES3 stream, or after 30 seconds of “silence” (level below -48dBFS). Failover
from analog to AES3 is based on the same silence sense algorithm, responding to audio
below -48dBFS for more than 30 seconds.
