General Description
The Rane MS 1 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 hassle.
The MS 1 provides 48 V switchable Phantom Power with
indicator LED, continuous rotary Gain trim between 21.5 dB
and 60 dB, overload LED, and XLR balanced Input & Output
connectors. A Phase Invert switch and high-current cross-
coupled output line drivers round out the features.
The MS 1 utilizes one of the finest ultra low noise
amplifier designs available. Featuring a true differential input
with high common-mode rejection, use of the MS 1 guaran-
tees performance usually found only in mixing consoles
costing thousands of times as much. Of course, for all of that
extra money you receive a proportional increase in KPSI
(knobs per square inch).
