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 L612, and L615 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 LIVE series in tilt back monitor positions, which will 

improve the projection of the speakers and may eliminate the need 

for speaker stands.  For larger settings (like clubs and parties), the 

L1212 and L1215 can be placed directly on the floor which causes a 

bass coupling effect that enhances the low frequency response. For 

even more bass, place a LIVE series on top of a powered sub woofer 

like the Samson dB1500a or dB1800a. 

The L612M is an ideal solution for stage monitoring and 

thanks to its unique low-profile design. In a large stage 

monitor system, several L612M’s can be daisy-chained 

together using the Line Output.  When positioning the 

monitor, be mindful of the placement of your microphones 

to help reduce feedback problems. It’s a really good idea to 

know your microphone’s pick up pattern to choose the right 

spot. Some microphones, like super and hyper cardioid 

models, offer a lot of rejection in the rear of their pick up 

pattern and when the L612M is positioned at the same 

angle as the rejection, you can set the monitor a lot louder 

before it feeds back. In many instances when using several 

L612M’s in 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. In this case 

be sure to set the HIGH and LOW EQ to the 12:00 or flat 

position.
