I know I can connect an audio signal to the A/D Input. But what exactly is “A/D”? I could not find anything in the manuals about what “A/D” stands for. The A could stand for analog or audio or auxiliary input… but then what does the D stand for?  First I thought Digital, but I can’t see what’s digital about that input. What am I missing? I keep thinking that if they don’t even bother to tell you, it might be something really obvious, but I’m not seeing it.

Per the XF, it would appear to refer to Audio/Data, as in sampling data.  I am not exactly sure how that translates to the MOX.

Per the description in the XF Owner’s Manual:

A/D INPUT jacks (page 47)
External audio signals can be input via these phone jacks
(1/4” mono phone plug). Various devices such as
microphone, guitar, bass, CD player, synthesizer can be
connected to these jacks and their audio input signal can be
sounded as the Audio Part of the Voice, Performance, Song,
or Pattern. In the Sampling mode (page 47), these jacks are
used for capturing audio data as samples. In addition, you
can use the special Vocoder feature by connecting a
microphone to this L jack and inputting your Voice to the
microphone.

Could just simply mean “Audio Data”.

A/D INPUT is a short way of saying Analog-to-Digital Input. An Analog input includes anything that you can plug into the 1/4” inputs on the back panel of the MOX - this includes microphones, guitars, basses, keyboards, CD players, Handheld playback devices. These represent analog input devices.

The signal is processed by the Analog-to-Digital convertors of the MOX into the digital domain, where the signal can be processed by the on-board MOX effects and routed to your DAW.

Digital audio signal cannot be heard - it must be converted back to analog by D/A (or Digital-to-Analog) convertors before you can send it to the audio outputs and on to your speaker system.

Ah. I knew you couldn’t plug a digital input into it, but I didn’t realize it was doing an analog to digital conversion on that signal. (I guess I never thought about it because all I’ve ever used it for is to plug something in to merge with the MOX’s own input, so I could plug both sound sources into a single amp input without using a mixer.) From a user functionality perspective, I’d still call the A/D designation rather cryptic, as the user does not necessarily know--or need to know--that such a conversion is happening somewhere in the signal path (and apparently the manual writers didn’t think it was important for the user to know either). But thanks for the info.

Sorry anotherscott, my guess sucked.  But hey, I learned something in the process!
