Features 
 
1.  Woofer:  The woofer unit is 4" in diameter. It includes a high-
temperature voice coil and 4" polypropylene treated paper cone. 
The woofer delivers balanced mid- and low-frequency response.     
 
2.  Tweeter: By employing a specially developed 1" silk cone, the 
tweeter can deliver an extremely natural response. It minimizes 
resonance by adapting a unique internal damping technology.   
 
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 AV42'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 AV42 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.  Volume Control: Use the volume control to set the output sound pressure from the AV42 to proper levels as required. 
 
7.  Speaker Wire Input/Output: Connect your speaker wire from the speaker wire output to the speaker wire input.  
 
8.  RCA Inputs: Use RCA cables (sold separately) to connect an external sound source to these inputs.  
 
9.  Power Switch: Use this switch to power the monitor on or off. 
 
10.  Power Cable Input (IEC): Insert the included power cable here.
