5 5.1 PreSonus AudioBox™ USB Tutorials Microphone Types Overview 5.0 5.1 Tutorials Microphone Types Hookup The AudioBox USB work with most types of microphones, including dynamic, ribbon, and condenser microphones. 5.1.1 Condenser Connecting to a Computer Studio One Artist Condenser microphones generally capture sound with excellent fidelity and are among the most popular microphone choices for studio recording and, increasingly, for live performance as well.
5 5.1 Overview Microphone Placement Hookup The following are a few recording applications to help you get started with your AudioBox USB. These are by no means the only ways to record these instruments. Microphone selection and placement is an art. For more information, visit your library or local bookstore, as there are many books and magazines about recording techniques. The Internet is also a great source of recording information, as are instructional videos.
5 5.1 Tutorials Microphone Types PreSonus AudioBox™ USB Overview Acoustic Guitar Hookup Point a small-diaphragm condenser microphone at the 12th fret, approximately 8 inches away. Point a large-diaphragm condenser microphone at the bridge of the guitar, approximately 12 inches from the guitar. Experiment with distances and microphone placement. Another popular method is using an XY microphone placement with two small-diaphragm condenser microphones. (See drum-overheads photo on the next page.
5 5.1 Drum Overheads (XY example) Point a dynamic microphone at the center of the snare, making sure it is placed so that the drummer will not hit it. Place a small-diaphragm condenser microphone under the drum, pointed at the snares. Experiment with the placement of both microphones. Also experiment with inverting the phase of the bottom microphone. This technique can be used in live applications.
5 5.2 Tutorials A Brief Tutorial on Dynamic Processing Overview 5.2 PreSonus AudioBox™ USB A Brief Tutorial on Dynamics Processing Hookup Studio One Artist software is included with the AudioBox USB. This powerful DAW includes an assortment of dynamics plug-ins. What follows is an excerpt from a brief tutorial on dynamics processing written by PreSonus president and founder Jim Odom. It is included to help you get the most out of Studio One Artist.
5 5.2 Overview Why do the best consoles in the world put compressors on every channel? The answer is simply that most instruments need some form of compression, often very subtle, to be properly heard in a mix. Hookup Why do we need noise gates? Studio One Artist Connecting to a Computer Consider the compressed-vocal example discussed earlier; you now have a 20 dB dynamic range for the vocal channel. Problems arise when noise or instruments (air conditioner, loud drummer, etc.
5 5.2 Tutorials A Brief Tutorial on Dynamic Processing PreSonus AudioBox™ USB Overview Hookup As the compression threshold is lowered, more of the input signal is compressed (assuming a nominal input-signal level). Care must be taken not to overcompress a signal, as too much compression destroys the acoustic dynamic response of a performance.
5 5.2 Hard/Soft Knee. With hard-knee compression, the gain reduction applied to the signal occurs as soon as the signal exceeds the level set by the threshold. With soft-knee compression, the onset of gain reduction occurs gradually after the signal has exceeded the threshold, producing a more musical response (to some folks). Connecting to a Computer Tutorials Tutorials Auto. Places a compressor in automatic attack and release mode.
5 5.2 Tutorials A Brief Tutorial on Dynamic Processing PreSonus AudioBox™ USB Overview the level of a signal by a factor of two. (e.g., if a level drops 5 dB below the expansion threshold, the expander will reduce it to 10 dB below the threshold.) Hookup Commonly used for noise reduction, expansion is very effective as a simple noise gate.
5 5.2 Overview Frequency Key Filter. Some gates offer a variable frequency control allowing the user to set a specific frequency band that the will cause the gate to open or close. Connecting to a Computer Hookup Noise Gating. Noise gating is the process of removing unwanted sounds from a signal by attenuating all signals below a set threshold. As described, the gate works independently of the audio signal after being “triggered” by the signal crossing the gate threshold.
5 5.2 PreSonus AudioBox™ USB Tutorials A Brief Tutorial on Dynamic Processing Overview Left/Right (Stereo) Overheads. The low ratio and threshold in this setting gives a “fat” contour to even out the sound from overhead drum mics. Low end is increased, and the overall sound is more present and less ambient. You get more “boom” and less “room.” Hookup Thresholdhold -13.7 dB RatRatioio 1.3:1 AttAttackack 27 ms Release 128 ms Fretted Instruments Connecting to a Computer Electric Bass.

5 5.3 PreSonus AudioBox™ USB Tutorials Equalizers Overview 5.3 Equalizers Hookup Studio One Artist also includes several EQ plug-ins. Here’s a brief explanation of how an EQ functions, as well as some charts to help you navigate the frequency ranges of various instruments so you can quickly choose the best EQ settings for your recordings and live mixes. 5.3.
Owner’s Manual Tutorials Equalizers 5 5.3 Overview 5 kHz. By setting a narrow bandwidth and boosting the attack a bit, you can achieve a punchier kick drum without overpowering the rest of the mix. Connecting to a Computer Hookup A broad bandwidth accentuates or attenuates a larger band of frequencies. The broad and narrow bandwidths (high and low Q) are usually used in conjunction with one another to achieve the desired effect. Let’s look at our kick drum again.
5 5.3 PreSonus AudioBox™ USB Tutorials Equalizers Overview High Mids (2 kHz to 4 kHz). The attack portion of percussive and rhythm instruments occurs in this range. High mids are also responsible for the projection of midrange instruments. Hookup Presence (4 kHz to 6 kHz). This frequency range is partly responsible for the clarity of a mix and provides a measure of control over the perception of distance. If you boost this frequency range, the mix will be perceived as closer to the listener.
