AIO Interface Module
The Interface Module is the heart of the AIO. It provides DC power to the modules from
its integrated AC/DC power supply. An embedded processor on the module
communicates with the host computer via USB. This processor:
1. Automatically configures itself according to the types of audio modules that are
installed, then reports the AIO model type, channel counts, and other pertinent
information to the host computer.
2. Routes audio between the computer and the appropriate audio modules.
3. Controls the audio modules according to commands sent from the computer or
passes the commands on to any processors on the modules themselves.
4. Downloads software from the host computer onto any modules that require it.
5. Stores calibration data for modules that need it in flash memory, retrieving and
using it whenever the AIO is powered on.
The AIO is a USB Audio 2.0 Class compliant device.
Power Supply
The Interface Module has a 60W AC/DC power supply that converts the incoming AC
voltage to 15VDC. This voltage is converted to several other needed DC voltages by
voltage regulators on the interface and audio modules. AC input voltage may range
from 90
– 264 VAC and be either 50 or 60 Hz.
CAUTION: The power supply has exposed high voltages present that pose a
shock hazard. Never remove the Interface Module or take off the AIO cover with
the AC power cable attached!
