The Rane MS 1S 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 1S provides 48 V switchable Phantom Power with an indicator LED, continuous rotary Gain trim between 15 dB and 60 dB, Signal/Overload LED, and XLR balanced Input & Output connectors. A Polarity switch and high-current cross-coupled output line driver round out the features.

The MS 1S 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 1S guarantees 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).

The MS 1S replaces the MS 1B Mic Stage with a new internal universal power supply. The width increases by one inch -- all other features are the same.
