M-Audio Studiophile AV 40 [3/10] Bass reflex port

AV 40 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 40'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 40 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 and 1/4"

TRS 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 40 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.
