Stereo Auxiliary Input and Headphone Output
 In addition to the main RCA inputs in the back, for maximum flexibility the StudioPro 3 monitors' stereo aux input makes it easy to plug in a secondary audio source—such as your portable music player. The speakers' volume control works on both inputs simultaneously. Additionally, a stereo headphone output next to the aux jack mutes the speakers' sound and redirects it to your headphones. 
 Natural Bass
 The M-Audio custom bass reflex port discharges very low-frequency signals and delivers smooth, substantial bass response. Need more? The rear-panel bass boost gives you additional low-frequency gain and makes the StudioPro 3 monitors flexible enough to perform well for different spaces and listening preferences.
 Monitor Pads
 High-frequency audio signals tend to be fairly directional. That's why M-Audio includes wedge-shaped monitor pads that assist you in placing your M-Audio StudioPro 3 units directly at your ears for an optimal listening sweet spot.
 Speaker Enclosure
 M-Audio StudioPro 3 speakers provide a more stable performance with a special medium-density fiberboard (MDF) and unique interior reinforcement that absorbs vibration and impact generated under extreme conditions. Carefully placed acoustic material makes StudioPro 3 monitor's sound much bigger than they are—resulting in smooth, natural bass response.
 M-Audio includes a pair of angled isolation pads with each set of StudioPro 3 desktop audio monitors.
