To suppress howling

By using the FEED BACK REDUCER buttons, you can
suppress howling by detecting the frequency bands in
which the howling may occur, and then reducing the gain
of those bands through the 5-band equalizer.
To detect the frequency bands in which
howling may occur in order to suppress
howling
Make settings on the microphone and the SRP-X500P to
suppress howling more effectively.
1
Set the reference level for the microphone.
While talking on the microphone in a normal voice,
adjust the TRIM control so that the REF. indicator
lights intermittently.
Note
When you use a wireless microphone, adjust the
attenuator on the microphone instead of the TRIM
control.
2
Adjust the volume on the SRP-X500P.
Set the input level control and the MASTER control
to 0 dB position.
3
Set up the microphone.
Place the microphone where it is used and adjust the
direction.
4
Adjust the speaker output.
Turn up the SPEAKER OUT control on the SRP-
X500P slowly until the speaker output reaches the
level to be heard from anywhere within the place. Be
sure to turn down the SPEAKER OUT control whose
corresponding speaker output is not used fully to –
dB.
5
Perform the howling suppression.
Keep pressing the FEED BACK REDUCER button
on the SRP-X500P for the corresponding MIC
INPUT connector for 2 seconds or more.
The button indicator flashes as the SRP-X500P scans
the frequency bands.
When the button indicator stops flashing and lights
up, howling suppression is completed.
Notes
• While the SRP-X500P is scanning the frequency
bands, the sound similar to howling may be output.
If the output sound is too loud, press the FEED
