Microphone Positioning

The Auro loudspeakers provide parallel jacks that can be used as extension outputs for 

connecting additional speaker cabinets. Be sure to read the earlier section on imped-

ance to insure a proper connection with your amplifier. To link two Auros, connect your 

amplifier output to one of the Input jacks of the first Auro. Then connect a cable from 

the second connector to an Input of the second Auro.

When selecting a power amplifier for your Auro cabinet, it is important to understand 

the type of program material that the speaker will be handling. If the material has 

frequent transient peaks, choose an amplifier that has a power rating not more than 

twice the RMS rating of othe Auro cabinet. This will offer extra headroom and deliver a 

clear signal to your speaker cabinet. Using a power amplifier with a low power rating 

will cause a clipped output signal, which may damage the speaker. Be sure to consult 

the users manual of the amplifier to ensure it has the correct power output for your 

speakers.  

Reducing Feedback

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

gets too close to a speaker, and the volume is high. Feedback results when the micro-

phone picks up the amplified signal from the speaker, amplifies it through the speaker 

again, and then picks it up again, and so on. In general, it is recommended that any live 

mic (a mic that’s on) be positioned behind the speaker enclosures. This will give you 

the best level from your system before feedback.
