P-SOLO Ribbon (P1R)
A proud new member of the TRUE Systems product line of precision mic preamps. The P-SOLO Ribbon is specifically designed to get the absolute best results from both new-technology and vintage ribbon microphones (and for that matter, dynamic mics also).
Through discussions with some ribbon mic manufacturers, we learned that the dimensions of the ribbon and some other factors result in resonant frequencies, which cause the output impedance of the mic to peak at those resonant frequencies. If you don't have a high enough impedance on your ribbon mic preamp, you can get sonic variations. A combination of fluctuating ribbon output and too low of an impedance on the mic pre will cause variations in sonic character. Since we were already a balanced servo design, we were able to remove all capacitors from the signal chain and increase the impedance of the unit.
In short, the P-SOLO Ribbon features the same design as all true systems preamps, but with no phantom power (potentially 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.
