Analog Audio Monitor Level
This selection determines the analog audio output level (“FSD” is full-scale-
deflection reading as measured on a VU meter). In addition to the front panel
monitor (headphone) output, this setting also effects the analog output via the
DB25 cable. Select from
• +24dBu, +18dBu, +15dBu, or +12dBu
Analog IO Select
This setting configures the analog audio input and output channels on the DB-25
connector. Choose from:
• 8-Out
• 4-In 4-Out (Ch 1-4 in, Ch 5-8 out)
• 4-Out 4-In (Ch 1-4 out, Ch 5-8 in)
• 8-In
Delay In and Out
Here you can set up to 6 frames (in tenths of a frame) of delay for the AJA device’s
audio input and output. The AJA Control Panel delays all audio outputs—SDI,
HDMI, and Analog. This feature is useful in compensating for the processing delay
of a video monitor when audio is being monitored directly from the Io X3 (for
example, when an audio mixer is connected to the DB25 analog audio inputs).
IMPORTANT: If you use this Control Panel delay, do not use other delay settings in your
applications, as they can conflict with one another.
Audio Mixer Screens
The Audio Mixer screen has two tabs; Capture Monitor and Playback Monitor.
These tabs display what sources are available for monitoring / mixing via the AJA
hardware when in either of those two modes (if applicable). The controls on this
screen are dedicated only to monitoring adjustments, and do not affect the level
at which inbound audio signals are captured to storage.
The selection check boxes and screen slider controls affect the following Io X3
outputs:
• SDI Embedded Audio Out
• HDMI Embedded Audio Out
• Analog Audio Out (via DB25 cable)
• Front Panel Monitor Out (headphone jack) - This level can also be adjusted
with the front panel gain knob, and is additive to the screen slider controls.
IMPORTANT: Even though you can hear changes in the signals and levels adjusted
with the Audio Mixer screen, these changes are NOT recorded to disk during
NLE Capture or Audio Punch In / Voice Over to Timeline. In addition, muting or
activating sources on this screen will not affect audio signals being recorded. The
Audio Mixer screen is dedicated for monitoring only, not program mixing.
The branching arrow on the lower right indicates which sources are being routed
for monitoring in that operating mode, and is colored blue when active and red
when disabled.
