A NOTE ABOUT ROLLS MICROPHONE TRANSFORMER PREAMPLIFIER
The Rolls Transformer Balanced Input Microphone Preamp features many advantages over other mic preamps. Among these are simplicity of design, 40db or higher CMRR (common mode rejection ratio) than transistor input mic preamps. This means much lower noise on long input lines, and very low distortion at high gain.
IMPORTANT NOTE WHEN SETTING UP MIXER:
When setting up the RM83T turn all channels that are not being used off (volume at 0). Each channel is always active and can generate hum. So if a channel is not being used the volume for that channel should be set at 0.
