Output 4

In 4-Column show mode, you have 4 independent caller outputs to 4 faders on the console, but require only 1 mix minus feed. All callers hear the one console mix-minus feed and each other.

♦♦ 1 in/1 out

This mix-minus option means each console only has to make a single mix-minus feed for the caller send audio and the Nx12 makes only one mixed caller audio output of all callers, to one fader on the console.

Like the 1 in/multiple out mode, this option sends the single mix-minus feed from the console to all callers.

Its main purpose is to accommodate older consoles that have only one mix-minus, or when only one fader is available for telephone calls. The disadvantage is that the operator has no control of the relative levels of the multiple callers. It relies upon the Nx12’s AGC to automatically adjust the multiple callers to a consistent level.

With One Show show mode and in any of the Two Show show modes, using this mix- minus mode means you have one caller output to each console, and one mix-minus caller input from each console.
