Frequently Asked Questions - StudioPro 3 M-AUDIO

How do I connect the StudioPro 3 to my computer?

Use the included 1/8" to dual RCA cable. Plug the 1/8" end into your computer's headphone jack and the RCA ends into the speakers' input. You can also use a standard RCA cable from your audio interface.

Why is there no sound coming from the speakers?

First, ensure the speakers are powered on (front LED lit). Check that the volume knob is turned up. Verify that your audio source is playing and the cable is fully inserted. If using a computer, check the audio output settings.

Can I use these speakers with a subwoofer?

Yes, you can connect a subwoofer to the audio source before the speakers, or use a subwoofer with speaker-level inputs. The StudioPro 3 has no dedicated subwoofer output, so you'll need to split the signal.

What is the optimal placement for the StudioPro 3?

Place them at ear level, forming an equilateral triangle with your listening position. Keep them at least 6 inches away from walls to avoid bass buildup. Tilt them slightly toward your ears if needed.

How do I clean the speakers?

Use a soft, dry cloth to wipe the enclosure. For grills, gently vacuum with a brush attachment. Never use liquid cleaners or abrasive materials.

What is the difference between the StudioPro 3 and other models?

The StudioPro 3 features a 3-inch woofer and 20W per channel, offering compact size and clear audio for near-field monitoring. Larger models like the StudioPro 4 have a 4-inch woofer and more power.

Can I mount these speakers on a wall?

Yes, they have a threaded insert for optional wall-mount brackets (not included). Ensure the mount can support the speaker's weight (2.1 kg each).

How do I reduce noise or hum?

Use shielded cables and keep audio cables away from power cables. Ensure all equipment is on the same electrical circuit. If hum persists, try a ground loop isolator.

Are the speakers magnetically shielded?

Yes, the StudioPro 3 are magnetically shielded, so they can be placed near CRT monitors or other sensitive equipment without causing interference.

What is the warranty period for the StudioPro 3?

M-Audio typically offers a 1-year limited warranty. Check your region's terms or contact support for details. Keep your proof of purchase.

Owner's manual

StudioPro 3 Features

1. Woofer

The woofer unit is 3.25" in diameter with a magnetically shielded curved cone to protect your computer video monitor from interference. It includes a high-temperature voice coil and is enclosed with acoustic foam damping. The woofer delivers balanced mid- and low-frequency response.

2. Tweeter

By employing a specially developed 1" dome with protective magnetic shielding, 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. Bass-Boost Control

The back panel Bass-Boost control on the StudioPro 3 gives you additional low-frequency gain and makes the monitors versatile for different spaces and listening preferences.

5. Enclosure

Along with the other components, the StudioPro 3'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 impact generated under extreme conditions. Additionally, our innovative speaker monitor cabinet includes carefully placed acoustic material that makes the StudioPro 3 sound much bigger than it is—resulting in a smooth, natural bass response.

6. 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 in the back. The volume control works on both 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.

7. Network & Power Amplifiers

The active equalization, crossover networks, and power amplifiers for the StudioPro 3 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.

8. (Optional) Speaker Stands

We have included a pair of desktop/bookshelf speaker monitor stands with your StudioPro 3 system. They help point the StudioPro 3 monitors directly at the listener, optimizing the “sweet spot” for listening. High-frequency audio signals radiating from the tweeters tend to be fairly directional, so by using the stands you can help focus those signals for exceptional audio imaging.

Two black audio/video speakers with speaker covers, no visible text or symbols on the devices themselves.

Installation

For optimal performance of the StudioPro 3, please read the following directions carefully before installation.

Precautions

Connections: Connect the RCA outputs of your StudioPro 3 to the corresponding computer sound card, portable music player, or other audio device. We recommend that you use the supplied cables (or cables of equal or higher quality) for all connections. Be sure that the StudioPro 3 monitors are powered off before making any connections.

If you need to connect the StudioPro 3 speakers to a device with 1/4" outputs, like the M-Audio MobilePre USB, you can purchase an adapter cable that will have the 1/4" connection on one end and the RCA connection on the other end.

Correct Power Operation: Since the StudioPro 3 contains amplifiers, it must be connected to a power outlet using the detachable AC cable that is provided. Before connecting power, please make sure that the On/Off/Volume switch of the StudioPro 3 is rotated all the way counterclockwise to the off position.

WARNING! - Use of improper Voltage may result in hazardous conditions and/or damage to speaker components not covered by speaker warranty.

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 StudioPro 3 monitors and on the bottoms of the speaker stands (if you choose to use the stands).

Speaker Wire Connections

Use the transparent 1/8" mini cable included in the StudioPro 3 package to connect the Left and Right speakers via the 1/8" mini jacks on the back of each speaker.

Connecting to a Computer Sound Card or Other Audio Output Device

Before connecting the StudioPro 3 monitors, make sure the power from the computer or other output device has been turned off and the StudioPro 3 system is also turned off.

Plug the RCA cable 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 StudioPro 3.

Setting the "Bass Boost" EQ Switch

This 2-position switch provides a subtle increase in bass response. The On mode increases the low-frequency gain slightly via the woofer and bass-reflex port. The Off mode produces a natural, even response for most listening conditions.

Please see Appendix C for the "Bass Boost" frequency response curve.

Placing the StudioPro 3

The way you position your speaker monitors can greatly affect the way they sound. Please refer to the following description for correct StudioPro 3 placement.

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

graph TD
    A["Left Unit"] --> C["Human Figure"]
    B["Right Unit"] --> C["Human Figure"]
    C --> D["Left Unit"]

1. Ideally, the tops of the woofers should be level with the listener's ears. Given the compact size of the StudioPro 3 monitors and typical desk heights, achieving this alignment may be difficult. Fortunately, we have provided speaker stands that can help point the StudioPro 3's directly at the listener.
