The basic assumption for Auto Switching is that
your Main (primary) signal is the default. As long
as this signal is available and valid as defined by
the Auto parameter’s setting, it will be processed
and sent to the Engine’s Stereo output as de-
fined on the Frame – Routing page.
As soon as the Main (primary) signal is not avail-
able/valid anymore, the Engine should process
the signal from the Auxiliary (secondary) input
instead and send this signal to the Engine’s Ste-
reo output.
The signal that is currently being processed and
sent to the Engine’s output is indicated in the up-
per right corner of the ALC2 window.

(primary) input active/highlighted.
Auto parameter
Use the Auto parameter to configure the condi-
tion that will trigger a fallback from the Main to
the Aux input as described above.
Off setting
When the Auto parameter is set to off, no input
switching/fallback will occur. Loudness Pilot will
always process the Main signal.
-60 dB / -50 dB settings
Use these settings to base Main signal availabil-
ity detection on the Main signal’s level.
If the Main signal’s level falls below this level
(-50 dB or -60 dB), the Engine will switch from
the Main (primary) to the Auxiliary (secondary) in-
put, process it and send it to the Engine’s output.
24 / 20 / 16 Bit settings
Use these settings to base Main signal availabil-
ity detection on the Main signal’s dithering.
For example, if you set the Auto parameter to 16
Bit, Loudness Pilot will monitor the signal on the
Main (primary) signal input for a dither noise level
at approximately -96 dBFS. If the noise level in a
silent period for the Main channels is below -96
dBFS, the Engine will switch from the Main (pri-
mary) to the Auxiliary (secondary) input, process
it and send it to the Engine’s output.
Dissolve parameter
Range: 25 ms to 3 seconds
Signal switching between Main and Aux signals
occurs in a power-compensated fashion. Use
the Dissolve parameter to set the cross-fade en-
gage and disengage time.
