g [Freq.]
Displays the frequencies of the filters that were applied. Up to seven filters will be applied.
The indicator will light when the following occurs.
- When a frequency is displayed
- When a currently-displayed frequency is rewritten
When using FIXED, calculation will continue repeatedly even after all seven
filters have been displayed, for example to combine the frequencies that are
closest to each other. However when using DYNAMIC, if all seven filters are
already displayed but new feedback is found, the filter that was specified first
and that will have the least effect on the audio quality will be discarded, and
replaced by the newly-specified filter. A filter will be discarded automatically
after a certain length of time has elapsed since it was applied.
It is not possible to completely eliminate all feedback in all environments.
If feedback increases when you raise a fader or the gain, and is not
automatically suppressed, lower the fader or gain to prevent the speakers from
being damaged.
Performing FBS detection for the FIXED type
In order to obtain good results, you should set up the mics, speakers, and other sound
equipment, and adjust the output EQ settings before performing detection. If you want,
FIXED can also be used in conjunction with DYNAMIC.
1. Adjust the power amp output volume.
While vocalizing into the mic, gradually raise the power amp output to the volume at
which the system will be operated in actual use. In addition, clap your hands and
verify that feedback does not occur.
2. Maintain silence in the space for which you want to suppress feedback.
3. Minimize the input of the mic that you want to detect.
To minimize the input, you can either adjust the input gain or use the fader to adjust
the output. In the components that you have placed, adjust the parameters of the
appropriate component.
4. Click the [DETECT] button to begin detection.
5. Gradually raise the input of the mic that you want to detect.
Feedback will occur, but the DME7 will immediately detect that frequency and insert
a filter.
Repeat this operation. When you have obtained a satisfactory result, click the
[DETECT] button to end detection.
If you don’t notice any result, it may be that detection has failed. Click the
[CLEAR] button to discard the detection result. If you want to make the settings
once again, adjust the position of the mics and speakers, adjust the volume,
