   AV 30 User Guide

3.   Bass Reflex Port

The hole in the rear panel is a bass reflex port.  It is designed to discharge very low frequency 
signals and enhance the overall bass response.   

4.   Enclosure

Along with the other components, the AV 30's enclosure plays an important role. In order to provide 
more stable performance, we used a special medium-density fiberboard (MDF) and unique interior 
reinforcement designed to absorb vibration and minimize distortion.  Additionally, our innovative 
speaker monitor cabinet includes carefully placed acoustic material that makes the AV 30 sound 
much bigger than it is—resulting in a smooth, natural bass response.

5.    Stereo Auxiliary Input and Headphone Output

For maximum flexibility, we have included a stereo “Aux” input which allows you to plug in a 
secondary audio source (such as your portable music player) in addition to the main RCA inputs. 
The volume control works on all inputs simultaneously. Additionally, there is a stereo headphone 
output next to the “Aux” jack that mutes the sound coming out of the speakers and redirects it to 
your headphones.

6.   Network & Power Amplifiers

The power amplifiers and crossover network, for the AV 30 are specially designed for this woofer 
and tweeter. The network distributes low-, mid-, and high-frequency audio signals to the proper 
components in order to minimize distortion and to achieve a balanced sound.
