INTRODUCTION

Thank you for purchasing the ROLLS MP13 MINI-MIC Microphone

Preamp. The MP13 uses a servo balanced instrumentation amplifi-

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.
