Positioning the RS15S and RS18S

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 Resound enclosures feature a standard 1 3/8” pole 
mount receptacle, which is compatible with speaker stands from a variety of 
manufacturers. 

Note: Be sure to check the manufacturers minimum recommended imped-
ance for your power amplifier to avoid overload and possible damage to both 
the speaker and amplifier. In many  instances when using the Resound 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.
