Appendix C Working with Professional Video and Audio Equipment 503
Connecting Professional Audio Devices
The steps for connecting audio playback and recording devices are similar to the steps
for connecting professional video devices. (For information on connecting professional
video devices, see “
Connecting Professional Video Devices ” on page 498.) Many
professional audio-only devices such as DAT recorders and Tascam DA-88/DA-98
multitracks also support remote device control and audio insert editing.
If you plan to capture footage using separate video and audio interfaces, you may need
to set up additional synchronization between your audio device and audio interface.
For more information, see “
Synchronizing Equipment with a Blackburst Generator ” on
page 504 as well as the documentation that came with your audio interface.
Connecting Professional Digital Audio Devices
Professional digital audio devices often use balanced XLR connectors. Each XLR carries
two AES/EBU digital audio channels. Connect the digital audio outputs of your video or
audio device to your audio interface (or its breakout box). If your video interface has
the appropriate connectors, you can also connect the audio outputs of your device to
the audio inputs on the video interface.
Note: Professional analog audio devices also use XLR connectors, but the signal is
incompatible with AES/EBU digital audio.
Connecting Consumer Digital Audio Devices
Consumer devices such as CD players, MiniDisc recorders, and some DAT recorders use
either an optical or RCA (coax) connector for S/PDIF digital audio. S/PDIF carries two
channels of digital audio, usually at a sample rate of 44.1 or 48 kHz and a bit depth of
16 bits. Connect the S/PDIF output of your audio device to the S/PDIF input on your
audio or video interface, if available.
Connecting Professional Analog Audio
Professional analog audio devices use balanced XLR or 1/4” TRS connectors for each
audio channel. Most audio interfaces that support multiple audio channels come with a
breakout box that contains all the connectors.
To connect multiple analog audio channels from a VTR or audio device to a
multichannel audio interface:
m Connect each audio output channel on the VTR or audio device to each audio input
channel on the audio interface or corresponding breakout box, if included.
