As a general guideline, try the +22dB setting for the output of professional mixing consoles; use the -10dBV
setting for devices such as consumer MP3 devices and CD/DVD players.

The AN-16/i v.2 has four input level options per channel pair.
To maximize the signal-to-noise ratio when setting up your Aviom products it is important to understand
how the input and output settings on these products interact. Proper calibration and gain staging with all
devices in an audio system is essential. The AN-16/i v.2 Input Module has four input gain range settings:
+22dBu, +4dBu, 0dBu, and -10dBV, accommodating a wide range of input signal sources. Choose the
setting that allows maximum input signal level without clipping.
The AN-16/i v.2 has a maximum input level of +22dBu. Signal levels above +22dBu will clip the input stage
of the device and cause digital distortion.
The selected input gain setting on the AN-16/i v.2 front panel changes the headroom available for the input
signal, but remember that the maximum input level will always be +22dBu regardless of the selection. See
the table below.

-10dBV +4dBV
0dBu +14dBu
+4dBu +18dBu
+22dBu +22dBu
With the input gain switch set to 0dBu, for example, input signals ranging from -∞ to +14dBu in level can
be used without clipping. A +14dBu signal level will be transmitted to all line-level output modules as a
full-code signal. Signals above +14dBu will clip the input stage of the AN-16/i v.2, and that clipped audio
data will be sent downstream to all Pro16 output modules and Personal Mixers. There are two options if
a signal level above +14dBu needs to be connected to the AN-16/i v.2 input: attenuate (lower) the output
level of the device feeding the AN-16/i v.2 channel input to eliminate clipping, or choose another input
setting. In this situation using the +4dBu setting provides more headroom, allowing a maximum signal
level of +18dBu to be used.
Check the specifications of your audio gear if you are unsure about its maximum output level. Although
you won’t harm the AN-16/i v.2 or your audio devices by using an incorrect level setting, you do want to
avoid distorting the audio that passes through the system.
