INTRODUCTION
Thank you for purchasing the ROLLS MP13 MINI-MIC Microphone
Preamp. The MP13 uses a servo balanced instrumentation ampli -
er 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 much
lower distortion. The clearer sound with more “air” puts the MP13 in
a class with much higher priced units.
