This area of the I/O module contains analog input jacks for Input Channels
1-4. (To learn about the M-16DX’s channels, see the Getting Started with the
M-16DX Workshop booklet.)
Connect a low-impedance mic cable to any of the four XLR jacks.

If your mics are condenser mics, you can supply phantom power from 2
the M-16DX by pressing in the PHANTOM +48V button. We’ll talk
about configuring the phantom power in a bit.
Plug an electric guitar or bass into either of these two 1/4” jacks and
3
press in the jack’s HI-Z button to convert it to a high-impedance
input. With the HI-Z button out, either jack is a line-level input to
which you can connect a mono electronic instrument—such as a
synth or beat box—or other line-level instrument or device.
These jacks are 1/4“ line-level inputs for connecting a mono
4
instrument or device.
Though you could plug the left and right sides of a stereo instrument
into a pair of the 1/4” jacks above, normally, we recommend using a
rear-panel pair of inputs instead so you can control both sides together
as a single stereo signal.
You can use a channel’s XLR or 1/4”-inch jack, but not at the same
time.

Configuring the M-16DX’s Phantom Power

By default, phantom power is supplied to all four XLR input jacks. If you
have a mix of condenser and non-condenser mics, however, you can direct
phantom power only to XLR Input Jacks 3 and 4, into which you can the plug
your condensers. To do this:
Hold down the CURSOR BWD and FWD buttons at the same time to
1
display the UTILITY menu.
Press FWD until the Phantom parameter is highlighted.2
Press - or + to select 3-4.3
Press DISPLAY to exit the UTILITY menu.4
Digital Connections
1 2
In this area of the I/O module front, we find—in addition to the DX BUS jack
we explained in Getting Started with the M-16DX Workshop booklet—the
M-16DX system’s digital inputs and outputs.
You can connect the S/P DIF-format coaxial or optical digital output
1
from an external digital audio device to the corresponding DIGITAL
IN (11/12) jack. This is routed to Input Channel 11/12 when Channel
11/12’s DIGITAL button on the M-16DX mixer is pressed.
You can use the DIGITAL IN (11/12) coaxial or optical input jack, but
not at the same time.
