3.10 CONFIGURE AUDIO
The Audio control group in the lower part of the Configuration panel has Input Type and Gain
control features for the external audio source in the same input group as the current video input.

The upper menu permits you to choose a different audio input to be captured with the video clip
for this camera. You can also disable audio for this input using the switch provided.
Input Type options include Mic (with and without phantom power), Line , AES/EBU , and SDI
Embedded . After connecting audio sources to the input connectors the first thing to do is select
the desired Input and correct Input Type using the drop-down menus:
• Select Mic for professional grade microphones or other low impedance connections
(use the Mic + Phantom option for condenser microphones requiring
supplementary power)
• Choose Line typically for consumer type device connections (such as a CD player,
computer audio output or VCR).
• Select AES/EBU or SDI Embedded to connect a digital audio source.
Note: Analog levels conform to SMPTE RP-155. The maximum input/output level is +24 dBu,
nominal input level +4 dBu (-20dBFS), and the sample rate is 48 kHz.
The Gain slider defaults to 0dB on first launch. After adding audio sources, slowly adjust the
slider to achieve an appropriate signal level (use the VU meters in the titlebar above the monitor
as an aid.)
