The Royer Labs R-122 is the world's first phantom powered, active ribbon™ microphone. Its unique electronics package gives the Royer Labs R-122 greater output than standard, non-powered ribbons, and places a perfect impedance load on the ribbon element, greatly expanding the number of preamps the mic operates well with.
Before the Royer Labs R-122, all ribbon microphones were passive devices. Tracking strings, acoustic guitars, vocals and other quieter sound sources required pre's with a lot of gain and a high input impedance. With the Royer Labs R-122, gain and impedance issues are a thing of the past, letting you use more pre's with great results.
Conventional ribbon microphones need high-quality, high-gain microphone preamplifiers to record softer sound sources. The Royer Labs R-122 is as sensitive as a condenser microphone, allowing you to use practically any mic preamplifier or board pre's to record even the quietest sounds. The Royer Labs R-122 contains a fully balanced, discrete head amplifier system utilizing a specially wound toroidal transformer and ultra-low noise FET's. This system is extremely quiet, can handle 135 dB SPL, and brings the Royer Labs R-122's sensitivity to 37 dB! Go ahead and plug an Royer Labs R-122 into any preamp with average gain - you'll get full Royer performance and enough level to drive any recording medium.
The Royer Labs R-122's higher sensitivity does not create additional self-noise. All of the Royer Labs R-122's increased sensitivity comes from its large, specially wound toroidal transformer - that wonderful thing called "free gain." The phantom powered circuitry provides impedance conversion only, adding no noise of its own.
The Royer Labs R-122's active electronics put a perfect load on the ribbon element at all times, allowing the Royer Labs R-122 to deliver 100% of its full sonic potential regardless of the input characteristics of the following mic pre. Due to its low-impedance output, Royer Labs R-122's can be used on extremely long cable runs with minimal signal loss. In addition, the ribbon element can't be damaged by phantom power, miswired cables or electrical glitches.
