Audio
The audio parameter defines which audio connection (or connec-
tions) you want to associate with this particular input. There are
some cases in which you may need more than a single audio
connection from a source component to the Nº40. You can asso-
ciate up to three input connectors with a single input definition. In
so doing, you also establish the priority of connection, with the
first input listed having the highest priority, followed by the
second, followed again by the third.
Keep in mind that audio from a selected HDMI input is available for
processing by the Nº40. However, audio processed by the Nº40 is
not available on the HDMI output. For digital outputs, note that
audio coming from HDMI inputs with HDCP-encoding is down-
sampled to a sample rate of 48kHz or less.
The following encoded audio formats are supported: PCM, Dolby
Digital, DTS, AAC, and THX. Note that digital signal processing is
performed at a sample rate of 48kHz.
There can be multiple sources of audio associated with an input.
The Nº40 migrates to the highest priority active audio. If the audio
becomes inactive, the Nº40 migrates to the next available active
audio. Analog audio is always considered active. The priority is as
follows:
1. HDMI
2. Digital (S/PDIF)
3. Analog
You can also assign a function key or toolbar to a direct command
that will force the Nº40 to migrate to the next type of input and
suspend the automatic migration. Auto-migration will resume
