The DTX-AO option includes
support for two audio recording channels (analog
output). These audio channels are in addition to
the main DataMAX II recording channels.
During recording the two audio inputs
are sampled and data stored into the industry standard
audio .WAV format.
During replay or viewing of recorded data the .WAV
file is played out through the DTX-AO analog outputs.
Connecting the outputs to external speakers gives
a two channel audio replay synchronized with the
data recording.
Applications include: voice annotation
of test parameters (similar to that available with
older multi-track tape recorders) and recording
background audio sounds within a test chamber.
