Setting a Frequency Range for Your Mic to Test
When you’re using your own mic, you should set the M-16DX to take best
advantage of the mic’s own frequency range by setting the M-16DX’s RAC
FREQ UTILITY parameters. Here’s how:
Hold down the CURSOR BWD and FWD buttons at the same time to
1
display a UTILITY screen.
Press FWD and/or BWD until the RAC FREQ >—for “RAC Frequencies
2
Greater Than”—value is highlighted.
Set the parameter to the value closest to the lowest frequency your 3
mic can capture.
Press FWD once and set RAC FREQ < (“RAC Frequencies Less Than”) to
4
the value closest to the highest frequency your mic can handle.
Press DISPLAY•EXIT when you’re done.

When you’re using the M-16DX’s built-in ROOM ACOUSTIC SENSOR, RAC
FREQ > should be set to 40 Hz, and RAC FREQ < should be set to 16
kHz.
Positioning the ROOM ACOUSTIC SENSOR or Mic
Place the M-16DX mixer’s ROOM ACOUSTIC SENSOR or your mic
at an equal distance from, and exactly in the middle of, your two speakers—

with nothing in the way.
This central location is also the best place
for you to mix from, of course.

most closely resembles what you’ll be hearing.
where it won’t move or resonate during the procedure.

Setting the M-16DX’s Volume
RAC requires a strong signal to work well. While the specific levels you should
use depend on your speakers, room, ampilfier settings, and so on, here are
some starting points. If you’re performing an RAC analysis and adjustment
for studio work—
• set the MAIN LEVEL knob to its 12 o’clock position, and
set the PHONES/CTRL ROOM knob to the same position.
for live sound—
• set the MAIN LEVEL knob to its 12 o’clock position.
If you need to raise or lower this level, the M-16DX will ask you to.
If you raise your output level higher than normal as you perform the
RAC analysis and adjustment, be sure to turn it back down to a normal
listening level before sending any other signals through the M-16DX.
Otherwise, you may end up blasting your speakers and yourself.
