MS 1
MICROPHONE STAGE
Application Information
Uses and applications for the MS 1 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 1 might not be wasted.
BALANCED USE
The MS 1 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 1 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 1's bal-
anced Output, connect pin 2 to the “+” or “hot” lead, and tie
pin 3 and ground together at the shield.
MIXING
The MS 1 is designed to fill the need for adding one or
two microphone channels 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 1 to the rescue.
DIGITAL RECORDING AND SAMPLING
Another handy use for the MS 1 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 1 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 1 allows the use of
virtually any type of microphone. True 48V phantom power
guarantees the MS 1 works with every microphone made. The
better the mic, the better the MS 1 sounds.
Ah, the sound of the thundering hoofs is deafening.
Architectural Specifications
The microphone preamplifier shall be a single channel
stand-alone unit with remote power supply. The power supply
shall be U.L. listed, C.S.A. certified, and CE certified. The
input and output shall be fitted with XLR connectors. A
polarity inverting switch shall be included. Phantom power
shall be provided in compliance with DIN 45596 & IEC 268-
15 and be controlled by a slide switch with an LED indicator.
A gain control shall be provided with 21.5-60 dB adjustment
range. A power indicator and a system overload indicator
shall be provided. High current cross-coupled active output
line driver shall be standard, as well as input RFI filter
protection.
The unit shall be a Rane MS 1 Microphone Stage.
CHASSIS GROUNDING
Units with outboard power supplies do not ground the
chassis through the line cord. Make sure that these units
are grounded either to another chassis which is earth
grounded, or directly to the grounding screw on an AC
outlet cover by means of a wire connected to a screw on
the chassis with a star washer to guarantee proper contact.
Please refer to RaneNote 110, “Sound System Inter-
connection” (supplied in your manual and available on
request separately) for further information on system
grounding.
