98 Chapter 7 External Audio and Video Monitoring
A FireWire DV setup is a common configuration. The FireWire device (either a
camcorder, VTR, or FireWire-to-analog converter box) converts DV signals to video and
audio signals connected to a video monitor and self-powered speakers. If you have a
home stereo system, you can also connect the audio output of the FireWire device into
any available channels on the home stereo system.
FireWire video and USB or FireWire audio
Using a FireWire or USB audio interface is an alternative to a DV-only setup. This
configuration can potentially handle more than two discrete audio channels and may
feature better digital-to-analog converters (depending on the interface). Most FireWire
audio interfaces have more audio channels than USB (1.1) interfaces.
Uncompressed video via FireWire using the AJA Io
The AJA Io is set up just like a standard DV setup using FireWire, but instead of using
compressed DV signals, the Io transfers an uncompressed component 4:2:2 signal. The
full Io unit supports SDI and analog outputs for analog or digital monitoring. There are
four analog audio outputs for monitoring via speakers.
