Samson db300a User Manual

Feedback is the annoying howling and squealing that is heard when the 

microphone 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 

your mixers 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.

Whenever possible, it is a good idea to raise the speakers above the heads of 

the listening audience. The dB300a enclosures’ feature standard 1 3/8” pole 

mount receptacles, which are compatible with speaker stands from a variety 

of manufacturers. In a smaller setting like a school cafeteria, library, or a mall 

kiosk, you can also use the dB300a in one of the tilt back monitor positions, 

which will improve the projection of the speakers and may eliminate the 

need for speaker stands. 

The dB300a is an ideal solution for stage 

monitoring and thanks to its unique design, 

two wedge monitor positions are possible. 

When placed on its side, with the high fre-

quency horn facing to the left of the enclo-

sure, the dB300a is tilted at a 30 degree angle, 

optimizing performance when used on a 

large stage.  When placed on its side with the 

high frequency horn facing to the right of the 

enclosure, the dB300a is tilted at a 45 degree 

angle optimizing performance when used 

on  smaller stages.  In a large stage monitor 

system, several dB300a’s can be daisy-chained 

together using the Line Output.  In many 

instances (when using the dB300a as a moni-

tor system) you may choose to use an exter-

nal equalizer like the Samson S Curve 131 to 

increase the volume and reduce the chance of 

feedback. In this case be sure to set the HIGH 

and LOW EQ to the 12:00 or flat position.
