R-122 MKll Active Ribbon Microphone
In 2002 we introduced the R-122, the world’s first phantom powered, active ribbon™ microphone. It was a revolutionary development in ribbon mics, combining impedance matching circuitry with condenser-like output levels that allowed the R-122 to be used on even the quietest sound sources. It also allowed the mic to be paired to virtually any preamplifier.
The R-122 MKll takes the R-122 to a whole new level, delivering unprecedented flexibility for ribbons via the addition of a switchable -15 dB pad and a switchable bass-cut filter. The switches are completely out of the circuit when disengaged so when both are off, the microphone is for all purposes an original R-122. The switches are located on the back of the microphone and recessed to prevent accidental activation.
The R-122 MKll’s switchable -15 dB pad is positioned before the microphone’s electronics and, when engaged, eliminates any potential for headroom-related distortion on even the loudest sound sources. Wide open electric guitars are no problem. With the pad in, the R-122 MKll’s output is actually 2 dB lower than our flagship R-121.
The R-122 MKll’s well-designed pad has no sonic imprint. Once levels are matched, the R-122 MKll reproduces sound exactly the same with the pad in as with the pad out.
The Bass Cut
When switched in, the R-122 MKll’s bass cut starts filtering at 100 Hz, 6 dB per octave, effectively reducing the mic’s bass buildup due to proximity effect. This smooth filter is extremely useful on vocals, many acoustic instruments, and close-miked electric guitars when less bottom end is desired.
The R-122 MKll’s electronics are hand-wired in our Burbank, CA factory. The microphone utilizes a special Royer-designed toroidal transformer that delivers a faster transient response then traditional ribbons, making it a first call ribbon mic for drum overheads, percussion and all acoustic instruments.
Conventional ribbon microphones need high-quality, high-gain microphone preamplifiers to record softer sound sources. The R-122 MKll’s output level is much higher, allowing you to use practically any mic preamplifier or board pre’s to record even the quietest sounds. The R-122 MKll contains a fully balanced, hand-wired, discrete head amplifier system utilizing a specially wound toroidal transformer and ultra-low noise FET’s. This system is extremely quiet and brings the R-122 MKll’s sensitivity to 37 dB, all while allowing for high SPL recording! Go ahead and plug a MKll into any preamp with average gain – you’ll get full Royer performance and enough level to drive any recording medium.
There is no increase in self-noise in the R-122 MKll’s higher sensitivity. All of the mic’s additional output 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 R-122 MK’s active electronics put a perfect load on the ribbon element at all times, allowing the microphone to deliver its full sonic potential regardless of the input characteristics of the following pre. Due to its low-impedance output, 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.
Patented Offset Ribbon Technology
The R-122’s proprietary offset ribbon transducer (Patent # 6,434,252) positions the ribbon element closer to the front (logo) side of the microphone. This configuration gives the ribbon more room to move within the prime magnetic field while maintaining full frequency response during high SPL recordings. It’s an integral piece of the magic of all Royer R-series microphones.
