ROLLS Corporation MP213 Dual Mic Preamp
Product Information
The MP213 Dual-Mic Preamp is a versatile audio device designed to enhance the
quality and performance of microphones. With its dual-mic capability, it
allows for the simultaneous connection and amplification of two microphones.
The preamp features multiple input and output options, including XLR and 1/8
(3.5mm) TRS-balanced mic inputs, as well as XLR balanced and 1/8 stereo
outputs. It is compatible with both balanced and unbalanced audio systems,
offering a wide range of connectivity possibilities. The impedance of the
inputs is 10K Ohms, making it suitable for various microphone types. The XLR
balanced output operates at a level of +4 dBV, while the 1/8 unbalanced output
operates at a level of +10 dBV. This ensures optimal signal strength and
compatibility with different audio equipment. The MP213 Dual-Mic Preamp
provides substantial gain control, with a maximum gain of 60 dB for XLR inputs
and 54 dB for 1/4 inputs. This allows for precise adjustment of the microphone
signal to achieve the desired audio levels.
Product Usage Instructions
- Connect your microphones to the preamp using either XLR or 1/8 (3.5mm) TRS balanced mic inputs. Ensure that the connections are secure.
- If using an unbalanced audio system, connect the XLR balanced output to your audio device using an XLR cable.
- If using a stereo system, connect the 1/8 stereo output to your audio device using an appropriate cable.
- Adjust the gain control knobs to set the desired amplification level for each microphone. Start with a lower gain setting and gradually increase it until the desired audio level is achieved.
- Monitor the audio output from the preamp through your audio device or headphones to ensure the signal quality and levels are satisfactory.
- Make any additional adjustments to gain control as needed to fine-tune the audio levels.
- When finished, disconnect the microphones and turn off the preamp.
Note: It is recommended to refer to the user manual of your specific audio equipment for any additional instructions or compatibility considerations.

The MP213 is designed to provide simple, in-expensive microphone pre- amplification for a variety of applications. The unit has both XLR and 1/8” inputs. XLR and 1/8” outputs, with a single Gain control with a Clip LED indicator for each channel. Phantom power is included for use with a condenser microphone. The 1/8” stereo output is specially designed for use as a camera microphone mixer or a moni-toring output. The MP213 uses a servo-balanced instrumentation amplifier for studio-grade performance in a small package. This equates to a 40 db better common mode rejection ratio (CMRR) than transistor inputs used by most companies on mic inputs. It also means much lower distortion.
