User manual RANE MS 1A DATASHEET

[. . . ] DATA SHEET MS 1a MICROPHONE STAGE General Description The Rane MS 1a Mic Stage preamplifier provides the answer when you need just one microphone input in an otherwise line-level world. Give us a call to go from either a dynamic, condenser or electret microphone to a line-level input with a minimum of noise, distortion, cost and hassle.

But then again, its obvious to us our taxes are too high and nothing is being done about that. With this in mind, perhaps a few words on using the MS 1a might not be wasted. This is equivalent to an electronic simulation of a transformer output. When running a long cable back to the mixer, run a linelevel balanced line rather than a mic-level line. The compact MS 1a can mount closer to the microphone, provide a local volume control (or not, just pull the knob off), while the stronger signal minimizes RF and hum irritations. When you must drive an unbalanced device with the MS 1a's balanced output, connect pin 2 to the "+" or "hot" lead, and tie pin 3 and ground together at the shield. MIXING The MS 1a is designed to fill the need for adding a microphone channel to line-level mixers, such as the Rane SM 26B or SM 82. Many installations using either of these products invariably wind up with one unused input that would do the job perfectly if only it could operate at mic-level. DIGITAL RECORDING AND SAMPLING Another handy use for the MS 1a is in recording applications. Many popular products do not have a high enough quality mic preamp to suit the resolution of the digital processing electronics. Using the ultra low noise MS 1a to bring the mic inputs up to extremely high quality line-level is an easy and affordable solution for this dilemma. MICROPHONE TYPES The available gain range of the MS 1a allows the use of virtually any type of microphone.
