18AN-16/i -M M ic iNput M odule user G uideChannel Input JacksThe rear panel of the AN‑16/i‑M Mic Input Module contains sixteen audio inputjacks. Microphones or line‑level audio signals can be used. The combo jackused 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 orcondenser microphones. Phantom power (+48V) is supplied for each channelfor use with condenser mics. The XLR input can also accept a line‑level audiosignal. But, be aware that using the XLR jack for a line‑level input can causeclipping with some extremely hot audio signals. If adjusting the Gain knob onthe front panel does not reduce the clipping, use the TRS input instead.2 14 3 2 14 3 2 1A-NetExpansion Main Out Aux OutA - N e t I n p u t M o d u l eAN-16Made In USAConceived, designed and manufactured by Aviom, Inc.Send SendReturn ReturnChannel 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.P Note : Do not connect guitars or other high impedance sources to theline‑level inputs. Use a direct box to convert a guitar or bass pickup’slow level magnetic signal to mic level.Balanced signals (sometimes referred to as TRS, for Tip, Ring, and Sleeve) arefound on many professional audio devices. The ¼‑inch connector used forbalanced 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 signalfrom 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 consumerelectronics. Only two connectors on the ¼‑inch plug are used, the tip and thesleeve. A standard musical instrument cable (sometimes called a guitar cord)uses this configuration, for example.
