INTRODUCTION
Thank you for purchasing the R OLLS MP13 MINI-MIC Microphone
Preamp. The MP13 uses a servo balanced instrumentation amplifier for
studio grade performance in a small package. This equates to a 40db
better common mode rejection ratio (CMRR) than transistor inputs used
by most companies on mic inputs. It also means m uch low er distortion.
The clearer sound with more “air” puts the MP13 in a class with m uch
higher priced units.
