Application Information
Uses and applications for the MS 1a should be obvious.
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.
BALANCED USE
The MS 1a 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 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.
UNBALANCED USE
Balanced use is recommended to minimize noise. 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. In
rides the MS 1a to the rescue.
DIGITAL RECORDING AND SAMPLING
Another handy use for the MS 1a is in recording applica-
tions. 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
MS 1a 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 range of the MS 1a allows the use of
virtually any type of microphone. True 48V phantom power
guarantees the MS 1a works with every microphone. The
better the mic, the better the MS 1a sounds.
Ah, the sound of the thundering hoofs is deafening.
