Advanced use
“Room acoustics” refers to the overall acoustical characteristics of the environment in which you’re
reproducing sound, including the response of the speakers you’re using.
The M-16DX provides a “Room Acoustic Auto Control” function, which automatically compensates for the
acoustics of a room. At the touch of a single button, this function performs the following operations:
(1) Outputs a test signal from the M-16DX, and plays this signal through the connected monitors.
(2) Detects the sound played by the monitors with the Room Acoustic Sensor, and analyzes its
frequency response.
(3) Based on the results of the analysis, automatically adjusts the response of the output signal.
The results of this automatic adjustment can be further edited manually if you wish.
When using the room acoustic control, the settings for the 16-band graphic equalizer (P.40) will be ignored.
Depending on the environment in which you are located, the automatic adjustment may not be enough to
provide the optimal response. In this case, you can perform manual adjustments in conjunction with the
automatic adjustment.
You can select whether room acoustic control will be applied to MAIN OUT jacks or PHONES/CONTROL
ROOM jacks.

In order to obtain the best possible results from this function, please observe the following points.
fig.RAC_Caution-e
• Place your equipment so that the room acoustic
sensor or mic (if the function switch is set to
EXT) is at the listening point.
• Place your equipment so that the left and right
monitors (speakers) are the same distance to the
sensor/mic.
• To the extent possible, place the sensor/mic at
the height of your ears at the listening point.
• Do not place obstructions near the sensor/mic.
• While the adjustments are being performed, do
not place the mix controller or mic on an object
that could resonate easily (such as a hollow box
or stand).
* Such an object could resonate with the test signal, causing slight vibrations that might interfere with accurate
measurement.
With monitors (speakers) that have a low output level, the test signal may not be detected, and the analysis
may fail to start. In this case we recommend that you perform the analysis manually (p. 39).
