StudioPro 3 User Guide English English StudioPro 3 User Guide English Introduction Thank you for choosing the StudioPro 3 professional desktop multimedia audio monitors. Top recording engineers and producers in studios around the world use M-Audio monitors. Now, with the StudioPro 3 monitors, you can enjoy the same professional standard of audio quality right on your desktop. The StudioPro 3 has been designed and tested by veteran audio engineers to meet your needs in a desktop audio monitoring environment. Custom-tuned cabinets, optimized speaker design, and advanced crossover technology deliver the best sound you can get in monitors this size. Complete with magnetic shielding for desktop use, StudioPro 3 delivers great audio experiences from your music and multimedia applications. The StudioPro 3 monitor is self-powered, directly accepting a line-level signal from a variety of sources. What's in the Box? Your StudioPro 3 box contains: < Your StudioPro 3 box contains: < Two StudioPro 3 speakers (Left and Right) Left: built-in amp and power supply; volume control, headphone jack, and auxiliary stereo input on front face; main RCA stereo input and right channel signal output on the back Right: audio connection from left speaker on back < One 1/8" stereo mini jack-to-RCA audio cable for use with the main inputs < Two speaker stands, designed to optimize the "sweet spot" for typical listening positions < 2-conductor standard (keyed) power cable < 1/8" stereo to 1/8" stereo audio cable (black color) for use with the "Aux" input < 1/8" to 1/8" audio cable to send right channel audio to the right speaker (transparent color) < Acoustic/traction pads for speakers and stands < Owner's manual 5 StudioPro 3 Features 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. 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. 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. 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. 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. 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. 1. Woofer 2. Tweeter 3.

Stereo Auxiliary Input and Headphone Output 6 StudioPro 3 User Guide English 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. 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. 7. Network & Power Amplifiers 8. (Optional) Speaker Stands Installation For optimal performance of the StudioPro 3, please read the following directions carefully before installation. 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. Precautions WARNING! - Use of improper Voltage may result in hazardous conditions and/or damage to speaker components not covered by speaker warranty. 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). Acoustic/Traction Pads 7 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. Speaker Wire Connections 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. Connecting to a Computer Sound Card or Other Audio Output Device 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. Setting the "Bass Boost" EQ Switch Please see Appendix C for the "Bass Boost" frequency response curve. 8 StudioPro 3 User Guide English 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. 2. 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. Figure 1: StudioPro 3 monitor at ear-level (no stand).
