Channel Input Jacks
The rear panel of the AN‑16/i‑M Mic Input Module contains sixteen audio input
jacks. Microphones or line‑level audio signals can be used. The combo jack
used for audio input can accept an XLR connector or a ¼‑inch TRS connector.
The XLR input is designed to accept microphone‑level signals from dynamic or
condenser microphones. Phantom power (+48V) is supplied for each channel
for use with condenser mics. The XLR input can also accept a line‑level audio
signal. But, be aware that using the XLR jack for a line‑level input can cause
clipping with some extremely hot audio signals. If adjusting the Gain knob on
the front panel does not reduce the clipping, use the TRS input instead.

Channel inputs accept XLR or TRS plugs; all Thru connection are XLR male.
The ¼‑inch part of the combo jacks can accept balanced or unbalanced line‑
level signals using TRS or TS plugs.

: Do not connect guitars or other high impedance sources to the
line‑level inputs. Use a direct box to convert a guitar or bass pickup’s
low level magnetic signal to mic level.
Balanced signals (sometimes referred to as TRS, for Tip, Ring, and Sleeve) are
found on many professional audio devices. The ¼‑inch connector used for
balanced audio wiring has three conductors: the tip, the ring, and the sleeve.
The balanced wiring system is ideal for keeping noise out of the audio signal
from sources such as radio interference (sometimes called “RF”).
Unbalanced audio signals (sometimes referred to as TS, for Tip and Sleeve)
are found on many effects processors, music keyboards, and consumer
electronics. Only two connectors on the ¼‑inch plug are used, the tip and the
sleeve. A standard musical instrument cable (sometimes called a guitar cord)
uses this configuration, for example.
