Microphone Positioning - How to Reduce Feedback
Feedback is the annoying howling and squealing that is heard when the micro-
phone gets too close to the speaker and the volume is high. You get feedback
when the microphone picks up the amplified signal from the speaker, and then
amplifies through the speaker again, and then picks it up again, and so on and
so on. In general, it is always recommended that any LIVE mic (a mic that’s on)
is positioned behind the speaker enclosures. This will give you the best level
from your system before feedback. One possible exception is when you are
adjusting the sounds of the microphones, since you want to listen in front of
the speaker to hear properly. To do this, lower the MAIN VOLUME while setting
the EQ and effect from in front of the speakers. Once you have the sound you
like, move the microphones to behind the speakers and raise the Main volume.
Speaker Placement
Whenever possible it is a good idea to raise the speakers above the heads of
the listening audience. The dB300 enclosure features a standard 1 3/8” pole
mount receptacle, which are compatible with standard speaker stands like the
Samson TS50 or TS100. In a smaller setting like a school cafeteria, library, or
a mall kiosk, you can also use the dB300 in one of the tilt back monitor posi-
tions, which will improve the projection of the speakers and may eliminate the
need for speaker stands.
Using the dB300 as a Floor Monitor
The dB300 is an ideal solution for stage moni-
toring and thanks to its unique design, two
wedge monitor positions are possible. When
placed on its side with the high frequency
horn facing to the left of the enclosure, the
dB300 is tilted at a 30 degree angle optimiz-
ing performance when used on a large stage.
When placed on its side with the high frequen-
cy horn facing to the right of the enclosure,
the dB300 is tilted at a 45 degree angle opti-
mizing performance when used on smaller
stages. In a large stage monitor system, sev-
eral dB300’s can be daisy-chained together
using the EXTENSION SPEAKER output.
Note: Be sure to check the manufacturers
minimum recommended impedance for your
power amplifier to avoid overload and possi-
ble damage to both the speaker and amplifier.
In many instances when using the dB300 as
a monitor system, you may choose to use an
external equalizer like the Samson S Curve 131
to increase the volume and reduce the chance
of feedback.
