CharterOak MPA-1 Stereo Microphone Preamp Overview

The CharterOak MPA-1 is an incredibly versatile stereo microphone preamp boasting the same "musical" quality the entire line is known for. With it's dual gain structure featuring both clean input and more saturated output gain control, the MPA-1's tone ranges from a very clean and detailed sound to a rounder, warmer transformer-based tone. Given it's tonal flexibility and practical feature set, including -10db pads and both high and low-pass filters, the MPA-1 is an excellent choice for both home and professional studios recording anything from vocals, to drums, to electric and acoustic guitars, and beyond. The MPA-1 is also available for Sound Pure's exclusive free try-before-you-buy demo program. Give us a call or shoot us an email for more info on how you can hear the MPA-1 for yourself in your studio with your gear. If you have any questions about the CharterOak MPA-1 or any of the additional pieces of gear used in this video don't hesitate to get a hold of any of us here at Sound Pure. Thanks for watching! 919-682-5552

Manufacturer's Description from CharterOak

The MPA-1’s transformerless input circuitry and transformer balanced output give the engineer the best of both worlds. With the input and output gain controls, the engineer can carefully control the signal from ultra clean and transparent, to pleasant coloration added by the MPA-1’s output stage and Cinemag output transformer.
The MPA-1 is also fitted with constantly variable high pass and low pass filters that encompass the entire bandwidth of the device, a -6dB pad, +48VDC phantom power, and phase reverse, giving the engineer further control of the signal and flexibility.
The mic pre is delivered with a lifetime warranty on all parts and labor and easy access to factory technical support.
