Rane MS1b Microphone Preamplifier (Desktop)
The Rane MS 1b 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 new MS 1b features an improved maximum input and improved dynamic range specifications. The new design features the popular Burr-Brown mic preamp chip which boosts performance tremendously.

The MS 1b provides 48 V switchable Phantom Power with indicator LED, continuous rotary Gain trim between 18 dB and 66 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 1b 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 1b 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).
