TUTORIAL 5: SETTING UP INPUTS
The M20 offers unparalleled flexibility in terms of setting up inputs for recording: signals can
come from analog sources, digital sources (ADAT optical or from optional AES/EBU cards),
or a combination of the two. As a result, it is important to understand the proper procedure
for selecting the right sources for the right inputs. The following gives an overview of the
process; for more details, see Chapter 6.
1If you are going to be using any digital sources, specify ADAT Optical or I/O Card using
the Digital Source button.
2Decide which track pairs will accept analog inputs, and which will accept digital inputs.
To do this, first press the Input Select button. Each push of one of a track pair’s Track
Input Enable buttons toggles between analog and digital (from the digital source selected
in step 1). A small “D” or “A” indicator lights under the VU meters to show the selected
input source.
3Set up the input routing for the analog signals by pressing the Input Routing button. This
function determines which inputs go to which tracks. For more details, see section 6.4a.
4Set up the input routing for the digital signals. Press the Input Routing button twice (or
only one more time if you are already in the analog routing page). There can be a simple
one-to-one correspondence (e.g., input 1 goes to track 1, input 2 goes to track 2, etc.) or
tracks can be reassigned.
5To reassign tracks, when in the digital routing page, press the Input enable buttons for
the desired digital source tracks. When you record-enable tracks, the lowest-numbered
source track will be assigned to the lowest-numbered record enabled track; the next-
lowest-numbered source track will be assigned to the next lowest-numbered record
enabled track; and so on.
Your inputs are now set up to record from the desired source tracks.
