Clean up your sound.
"Hum" in an audio system is often caused by loop effects which act like antennas. These loops can easily pick up a 60 Hz (or higher harmonics) hum transmitted by electrical wiring. Typically, these loops are connected via grounds, more commonly called "ground loops". The safest way to eliminate unwanted noise is with the CleanBOX II. Some examples of Ground Loops:
48V Phantom Power Supply
Different condenser microphones specify different amounts of required phantom power. As a rule these ratings can range from 48 volts all the way down to 9 volts. Fortunately, there is some flexibility in terms of matching phantom voltage to your mic. A rough rule of thumb would be "more is better."
For example, a 24-volt condenser mic will run perfectly on 48 volts. In fact, mics rated at as little as 9 volts can often operate on 48 volts, but you should check with the manufacturer first. Conversely, a mic will generally perform best driven by not less than its rated voltage so, for a 48V mic, you would obtain best results with 48 volts of phantom power. The Phantom I is a great choice for the above needs.
A great USB compatibale mic preamp on a budget.
The USB Dual Pre is a full-featured high quality dual portable preamplifier and computer interface packed into a compact rugged case.
It is designed to work over a wide variety of applications from remote field recording to desktop/studio tracking. Each of the two low noise input channels has up to 48 dB of clean gain with signal present and clip LED indicators. Inputs can be either XLR balanced or 1/4-inch TRS. Each of the 1/4-inch TRS outputs is buffered low impedance balanced.
The Shure BETA®57A is a high output supercardioid dynamic microphone designed for professional sound reinforcement and project studio recording. It maintains a true supercardioid pattern throughout its frequency range. This insures high gain-before-feedback, maximum isolation from other sound sources, and minimum off–axis tone coloration. Excellent for acoustic and electric instruments as well as for vocals, the extremely versatile Beta 57A dynamic microphone provides optimal warmth and presence. Typical applications include drums, guitar amplifiers, brass, woodwinds and vocals.
