Engineering Setup — Audio
The Audio tab in the Mira Engineering Setup menu is used to select the digital audio input sources, the number of audio tracks to use
in new clips created in Mira, and to determine which video channel(s) to monitor on the analog audio monitoring jack(s) located at the
top edge of the video board(s) on the Mira server rear panel.
NOTE: All Mira 8-Channel servers and Mira 4-Channel servers purchased and delivered after June 2010 do not feature built-in AES
digital audio I/O, and require an external 1RU “Digital Audio Breakout Panel” option to have AES digital audio I/O.
Mira 4-Channel servers delivered before June 2010 featured built-in 2-track AES digital audio I/O (on each video channel).

Audio Tracks
2 track / 4 track / 8 track / 16 track

when recording new clips into the server.

previously recorded clips retain and use the number of audio
tracks with which they were originally created.
NOTE: The “16 track audio” requires a software option.
NOTE: “16 track” & “8 track” settings are not available when
operating in Mira in SD (525 or 625).
Analog Audio Monitor

Assigns the desired video channel to the analog audio monitoring jack located at the TOP of the ChA/B/C/D video
board on the rear panel of Mira.
NOTE: The 3.5mm analog audio monitoring jack monitors only audio tracks 1-2 at this point in time; it’s not yet possible to select any other
audio track pair (i.e. 3-4; 5-6, 7-8, etc.) for monitoring on this monitoring jack.
NOTE: The 3.5mm analog audio monitoring jack is located at the top edge of the video board on the Mira server rear panel.
