Click the source menu at the top of the panel to display
connection options for an input (Figure 3-18). Audio
options are similar to video, in that you will see local
hardware inputs (shown as “IN 1”, “IN 2”, etc.) along
with network sources, including both NDI audio and
(Audinate™) Dante sources.
Generally, hardware inputs default to “line level”. As
when configuring video inputs, choosing a local
hardware audio source causes a configuration ‘gear’
icon to be displayed at right. Again, clicking the gear
opens the Hardware Configuration panel.
In this case, you will need to use the menu in the Audio
Source column for the input you are configuring to choose an appropriate connection type, such as Line,
Microphone, or perhaps SDI or HDMI (Figure 3-19 – options vary by model).
Note: Analog audio levels conform to SMPTE RP-155. The maximum input/output level is +24 dBu, nominal
Mic input level +4 dBu (-20dBFS), and the sample rate is 96 kHz.

Select Mic for professional grade microphones or similar sources. On supporting models, use the
Phantom option for condenser type microphones requiring supplementary power.

Choose Line for most other analog sources (including consumer devices such as a CD player,
computer audio output or VCR).

For 4RU models only, select AES/EBU for digital audio from an AES/EBU (AES3) source.
 SDI Embedded or HDMI provide digital audio from the associated video connection.
Hint: Some variation exists as respects signal levels from individual sources, even within the same type. For
Mic (and Mic + Phantom) connections, Gain (a.k.a., Trim) controls are provided to allow fine tuning of the
input level.
Returning to the audio Input Configuration panel (Figure 3-18), note that it holds both basic and advanced
audio features. In the former category, volume sliders are provided below VU meters for each audio source
and output. Source sliders default to their lowest setting on first launch. After adding audio sources, slowly
bring these sliders up to pass their respective signals through the system.
