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 toindicate that the input to a channel is causing audio clipping. Signal and Clip LEDs appear directly beneaththe channel numbers.The lower LED, marked SIgNAl, will light as long as an audio signal of at least -40dB is present on thechannel. It provides an easy way to confirm that audio is indeed passing into the AN-16/i v.2 and beingconverted to A-Net.The upper LED is marked ClIp. 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 ofpercussive sources will typically peak for a few milliseconds, for example). If the LED is on constantly, youshould either lower the level of the source audio coming into the AN-16/i v.2 or try different Input Levelsettings.Input Level SwitchThe AN-16/i v.2 has been designed to accept a wide range of professional and semi-professional audiolevels. There are four Input Level gain settings available. Changes to the input level on the AN-16/i v.2 frontpanel affect a pair of channels at a time.The four levels are +22dBu, +4dBu, 0dBu, and -10dBV. To select the proper Input Level setting, choosethe Input Level position that most closely matches the maximum output level of the audio gear beingconnected to the AN-16/i v.2 rear panel TRS jacks.
