 Example settings for MTX Editor
• Distance setting
For a simple configuration in which the distance between the microphone and speaker is within two meters, there is no
need to change this setting in MTX Editor.
If the distance between the microphone and speaker is greater than two meters, use the [Distance] knob to specify the dis-
tance.
• Echo cancellation depth setting
If there is a large amount of echo, use the [Effect] list box to adjust the depth of echo cancellation. Higher numeric values
allow more echoes to be cancelled. However, this will degrade the audio quality correspondingly, so consider the trade-
off as you adjust this.
• FBS setting
The MTX5-D provides two types of FBS: DYNAMIC and FIXED. In this project file, the DYNAMIC setting of the
MTX5-D unit is turned on. As needed, use the “INPUT” screen to set the FBS setting to FIXED. For details on how to
make this setting, refer to the “MTX Editor User’s Manual.”
• To make echo cancellation work effectively
Do not use GATE, COMP, AGC, or LIMITER, and do not operate the faders or gain while the system is in use. Doing so
will decrease the effectiveness of echo cancellation.
•XMV attenuator value
In this project file, the XMV’s attenuator value is set to -99. For meeting room ‘A’, access the “XMV” screen and set the
CH A attenuator value to an appropriate value. For meeting room ‘B’, access the “XMV” screen and set the CH C atten-
uator value to an appropriate value.
NOTE
FBS is also provided by the MY4-AEC; however, because the FBS of the MTX5-D allows more flexible settings, you should use the FBS
of the MTX5-D.
