AN-16/i Input Module
This section explains the basic layout of your new Aviom Pro16 product. The
diagrams on the previous pages can be used as a quick visual guide to the
location of the components mentioned in this section.
AN-16/i Front Panel
The front panel of the AN-16/i contains the channel information, Stereo Link
switches, Signal Present LEDs, Clip LEDs, Power indicator, and the Input Level
switches.
Channel LEDs
The numbered Channels on the AN‑16/i front panel correspond to the
sixteen line‑level analog audio inputs on the rear panel of the AN‑16/i. 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 Signal, 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—and being converted to A‑Net by—the AN‑16/i.
The upper LED is marked Clip. It will light if a signal reaches a point that is
within 3 dB of full scale (0dB). In general, you want to operate the system
so that the Clip LED lights only occasionally. If the LED is on constantly, you
should either lower the volume of the source audio coming into the AN‑16/i
or try different Input Level settings.
