TUTORIAL 7: USING THE M20 WITH UNBALANCED

INPUTS AND OUTPUTS

It is possible to use unbalanced signals with the M20, however you will need adapters like the following:

Note that it is probable that unbalanced lines will not have enough level to drive the M20 to full scale, and will require preamplification, or the input trimmers of your M20 must be reset to accommodate lower levels. The standard factory setting is +19 dBu = 0 dBFS (just before clipping). A mixer with a standard output of +4 dBu at 0 VU should light “-15 dB” on the M20’s meter.
