But then again, it's 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 MS1S might not be wasted. BALANCED USE The MS1S provides a true cross-coupled balanced output. This is equivalent to an electronic simulation of a transformer output. Rane follows the AES standard of pin 2 = hot. When running a long cable back to the mixer, run a line-level balanced line rather than a mic-level line. The compact MS 1S 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. UNBALANCED USE Balanced use is recommended to minimize noise. Unbalanced lines are usually quiet under 10 feet (3 meters), but longer runs will introduce the hum and interference you are trying to avoid. When you must drive an unbalanced device with the MS1S's balanced output, keep the cable short, and connect pin 2 to the "+" or "hot" lead, and tie pin 3 and ground together at the shield. MIXING The MS1S is designed to fill the need for adding a microphone channel to linelevel mixers, such as the Rane SM 26S or SM 82S. 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 miclevel. In rides the MS1S to the rescue. DIGITAL RECORDING AND SAMPLING Another handy use for the MS1S 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. Such irony. Using the ultra low noise MS1S to bring the mic inputs up to extremely high quality line-level is an easy and affordable solution for this dilemma. No garbage in; no garbage out. Clippity-clop; clippity-clop. MICROPHONE TYPES The available gain and large input range of the MS1S allows the use of virtually any type of microphone. True 48V phantom power guarantees the MS1S works with every microphone. The better the mic, the better the MS1S sounds. Ah, the sound of the thundering hoofs is deafening. Data Sheet-3
