The front panel of the AN-16/i v.2 contains the channel information, Mono/Stereo link switches, Signal Present LEDs,
Clip LEDs, A-Net In and Power indicators, and the Input Level switches.
Channel LEDs
The numbered Channels on the AN-16/i v.2 front panel correspond to the sixteen line-level analog audio
inputs on its rear panel. They are grouped together in pairs—Channels 1 and 2, Channels 3 and 4, etc.
Each channel contains two LEDs, one showing that there is an audio signal present, and another used to
indicate that the input to a channel is causing audio clipping. Signal and Clip LEDs appear directly beneath
the channel numbers.
The lower LED, marked S
IgNAl
, will light as long as an audio signal of at least -40dB is present on the
channel. It provides an easy way to confirm that audio is indeed passing into the AN-16/i v.2 and being
converted to A-Net.
The upper LED is marked C
lIp
. It will light if a signal reaches a point that is within 3dB of full scale (0dB).
In general, you want to operate the system so that the Clip LED lights only occasionally (the transients of
percussive sources will typically peak for a few milliseconds, for example). If the LED is on constantly, you
should either lower the level of the source audio coming into the AN-16/i v.2 or try different Input Level
settings.
Input Level Switch
The AN-16/i v.2 has been designed to accept a wide range of professional and semi-professional audio
levels. There are four Input Level gain settings available. Changes to the input level on the AN-16/i v.2 front
panel affect a pair of channels at a time.
The four levels are +22dBu, +4dBu, 0dBu, and -10dBV. To select the proper Input Level setting, choose
the Input Level position that most closely matches the maximum output level of the audio gear being
connected to the AN-16/i v.2 rear panel TRS jacks.
