    4 general description the rane ms1s 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 ha...

  • Page 5: Application Information

    5 application information uses and applications for the ms1s should be obvious. But then again, it’s ob- vious 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-...

  • Page 11: Introduction

    11 introduction this note, originally written in 1985, continues to be one of our most useful references. It’s popularity stems from the continual and perpetual difficulty of hooking up audio equipment without suffering through all sorts of bizarre noises, hums, buzzes, whistles, etc.— not to mentio...

  • Page 12: Ground Loops

    12 ground loops almost all cases of noise can be traced directly to ground loops, grounding or lack thereof. It is important to understand the mechanism that causes ground- ing noise in order to effectively eliminate it. Each component of a sound system produces its own ground internally. This groun...

    13 the absolute best right way to do it the method specified by aes48 is to use balanced lines and tie the cable shield to the metal chassis (right where it enters the chassis) at both ends of the cable. A balanced line requires three separate conductors, two of which are signal (+ and –) and one sh...

    15 the next best right way to do it the quickest, quietest and most foolproof method to connect balanced and unbalanced is to transformer isolate all unbalanced connections. See figure 2. Many manufacturers provide several tools for this task, including rane. Consult your audio dealer to explore the...

    16 the last best right way to do it if transformer isolation is not an option, special cable assemblies are a last resort. The key here is to prevent the shield currents from flowing into a unit whose grounding scheme creates ground loops (hum) in the audio path (i.E., most audio equipment). It is t...
