The P-Solo Ribbon Mic Preamp is specifically designed to get the absolute best results from both new-technology and vintage ribbon microphones (and for that matter, dynamic mics also).The p-solo ribbon microphone preamp features the same design as all TRUE Systems preamps, but with no phantom power (dangerous to most ribbon mics), no capacitors in the signal path, even higher input impedance, and higher gain capability. Whether you're recording Bach or rock, every time a ribbon mic is used, choose the same preamp preferred by many professional musicians, engineers and producers for critical studio, location recording, and live sound situations.About TRUE Systems:TRUE Systems is a product line of Sunrise Engineering and Design Inc., which is involved with consulting, design, and manufacture of electronic equipment used in professional audio production (recording and broadcast studios, concert halls, remote recording and live sound, etc.).The principal of Sunrise Engineering and Design,Tim Spencer, has thirty years of diverse experience in design, development, integration and manufacturing of complex hardware and software systems.
