Introduction

Thank you for choosing the AV 40 professional desktop multimedia audio monitors. Top recording engineers and producers in studios around the world use M-Audio monitors. Now, with the AV 40 monitors, you can enjoy the same professional standard of audio quality right on your desktop.

The AV 40 has been designed and tested by veteran audio engineers to meet your needs in a desktop audio monitoring environment.

1. Woofer

The woofer unit is 4" in diameter and is magnetically shielded to protect your computer video monitor from interference. 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 with protective magnetic shielding, the tweeter can deliver an extremely natural response. It minimizes resonance by adapting a unique internal damping technology.

3. Bass Relex Port

The hole in the rear panel is a bass relex 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 iberboard (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 lexibility, 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 Ampliiers

The power ampliiers 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.

Installation

For optimal performance of the AV 40, please read the following directions carefully before installation.

Precautions

Connections: Your AV 40 monitors have a variety of inputs for use with a multitude of devices.

Soundcards or other devices with RCA line outputs (e.g., M-Audio Delta Audiophile 24/96) can be connected to the RCA inputs on your left speaker’s back panel. Professional audio devices with balanced or unbalanced 1/4” outputs should be connected to the 1/4” TRS back panel inputs. If your soundcard or portable music player has an 1/8” output, you can connect it to the front panel aux input, using the provided 1/8” to 1/8” cable.

Correct Power Operation: Since the AV 40 contains ampliiers, it must be connected to a power outlet. Before connecting power, please make sure that the On/Off switch on the back of the AV 40 is set to the off position.

Acoustic/Traction Pads

In order to minimize vibrations and maximize physical stability, we recommend you use the provided acoustic/traction pads on the bottoms of the AV 40 monitors.

Speaker Wire Connections

Use the red and black cable included in the AV 40 package to connect the Left and Right speakers via the red /black spring-clip terminals on the back of each speaker.

Connecting to a Computer Sound Card or Other Audio Output

Device

Before connecting the AV 40 monitors, make sure the power from the computer or other output device has been turned off and the

AV 40 system is also turned off.

Connect the 1/4" or RCA input jacks to the corresponding output connectors of a computer sound card, portable music player, etc.

You can also use the black 1/8" stereo mini cable to connect a secondary audio device to the “ Aux ” input on the front of the AV 40.

Placing the AV 40

The way you position your speaker monitors can greatly affect the way they sound. Please refer to the following description for correct AV 40 placement.

1. The two speaker monitors and the listener should align to form an equilateral triangle.

2. Ideally, the tops of the woofers should be level with the listener's ears.
