NOTICE
Access to this screen is disabled during record.
The maximum frame rate that can be set is dependent on the type of media and the
codec.
If the desired frame rate cannot be set because it is grayed out, change the codec to
one with a lower data rate.
There are shortcut buttons on the FPS screen for CODEC, INFO and SDI FPS. In the
SDI FPS screen, MON OUT 1/2/3 frame rates can be adjusted within the limits of their
current format.
The MON OUT should match the sensor frame rate. If the sensor frame rate exceeds
the available MON OUT frame rates, set the MON OUT to half the sensor frame rate if
possible to maximize the smoothness of the image when panning and tilting.
To correctly set frame rates for the MON OUT:
1. Press the MENU button.
2. Using the jogwheel, select the Monitoring menu.
3. Select MON OUT.
4. Set Frame rate to the same frame rate as the sensor frame rate. If the sensor
frame rate exceeds the range of the available MON OUT frame rates, set the MON
OUT frame rate to half the value of the sensor frame rate.
5. Press the HOME button to exit.
13.1.3.3 AUDIO
Press the AUDIO button on the HOME screen to open the AUDIO screen. This screen
shows the ALEXA’s two audio channel levels. The audio levels are displayed from -45
dBFS to 0 dBFS.
NOTICE
No audio meters are displayed on the HOME screen or AUDIO screen when audio
is set to Off or audio is disabled. Audio is disabled when the sensor frame rate does
not match the project frame rate. In this case, no audio is transmitted via HD-SDI.
Light blue markers show reference levels of -20, -18 and -9 dB FS.
Red markers at levels -1 and 0 dBFS warn of clipping. With proper audio signal levels,
the red markers should almost never be visible.
