Audio I/O Module
The Audio Input/Output Module (AIO) handles audio functions such
as CW and PW Doppler, microphone, physio beeps and PC generated
beeps. The audio processing such as volume control, filtering, mixing
and scaling occurs on the motherboard which delivers five different
audio streams. The AIO receives these via a USB bus from the
motherboard via the backplane.
Obtains three different supply voltages via the backplane: 3.3Vdc,
+5Vdc and 12Vdc.
Has a USB hub for data input and output to the audio codecs.
Contains PIC for power monitoring functions.
Has three audio codecs:
1. Audio Codec with microphone input, outputs to DVD. (Right
channel only) Note: no playback capacity from DVD.
2. Audio Codec and two amplifiers that output to the system
monitor's two high frequency speakers.
3. Audio Codec and amp to subwoofer mounted above VPPM.
