Application Information
Uses and applications for the MS 1b should be obvious. But then
again, it’s obvious to us our taxes are too high and nothing is be-
ing done about that. With this in mind, perhaps a few words on
using the MS 1b might not be wasted.
BALANCED USE
The MS 1b 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
1b 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 MS 1b'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 MS 1b 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 1b to the rescue.
DIGITAL RECORDING AND SAMPLING
Another handy use for the MS 1b is in recording applications.
Many popular products do not have a high enough quality mic
preamp to suit the resolution of the digital processing electron-
ics. Such irony. Using the ultra low noise MS 1b 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 MS 1b allows
the use of virtually any type of microphone. True 48V phantom
power guarantees the MS 1b works with every microphone. The
better the mic, the better the MS 1b sounds.
Ah, the sound of the thundering hoofs is deafening.
