CharterOak, manufacturers of high quality, professional audio products will release the next in its line of preamps and signal processors, the MPA-1 microphone preamplifier. The MPA-1 will be shown at the upcoming Frankfurt Musikmesse in April, (Hall 5.1 A72). The CharterOak MPA-1 is a solid-state, dual channel microphone preamplifier that exhibits audio quality of the highest order. To achieve this end, the MPA-1 employs the highest quality components in a design that provides high headroom for years of trouble free use. 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.
