R-122V active ribbon microphone. Active Ribbon Technology Royer Labs pioneered the first active ribbon microphones with the introduction of the R-122 in 2002. The R-122 is a solid-state microphone that operates from standard 48-volt simplex power. - Page 4 R-121 (the R-122 also utilizes this special Royer designed transformer). Compared with that of the R-121, the transient response of the R-122 and R-122V is faster, giving the sense of a more open high-end response.

Page 5: Description
Applications The Royer Labs model R-122V is a versatile microphone and is ideally suited for many critical recording applications. Its smooth frequency response characteristics and ability to capture detail make it a fine choice for many instruments, as well as for general broadcast applications. -

The cable is specific to Royer products and may not be substituted with a cable from another manufacturer unless the pin out and wiring configuration are identical to the R-122V's cable. -

extending the life of the tube. We recommend letting the R-122V warm up for at least 15 minutes prior to use. When the microphone becomes operational, bring the channel fader to 0-dB (unity) and use the trim to set the desired level. This technique maximizes the signal-to- noise performance of the preamplifier or console input channel. -

Never attempt to bypass a fuse or use one of a higher rating! Not only is this an unsafe practice, but it will void the factory warranty. Voltage Changeover The power supply can be set to operate from voltages ranging from 100 to 240 volts AC. For 230V operation, use the 240V setting. -

“mic sock” (supplied with every Royer microphone) over it until it is to be used. Do not carry the microphone around without placing a mic sock over it. Failure to follow this commonsense practice may yield a stretched ribbon and compromised performance. - Page 10 but remember that you get what you pay for. If you have the opportunity to audition one or more preamplifiers before you buy one, do so. Microphones and preamplifiers work together like a team and some are better matches than others. The R-122V vacuum tube ribbon microphone is capable of substantial output signal, especially if used in conjunction with very loud signal sources such as guitar amplifiers.

microphone away from it. Another trick is to alter the orientation of the microphone in such a way that the noise is cancelled out. If you ever experience this situation while in the studio, try rotating the microphone to identify the “null” point, and then reposition the mic and the sound source. -

square law. The inverse square law states that for each halving of source-to-microphone distance, the sound pressure level quadruples. Other Types of Microphones For the same ratio of direct to reverberant sound, omni-directional microphones must be closer to the sound source than cardioid or bi-directional microphones. Microphones should generally face the sound source head-on;... -

Microphone Techniques General Tips for Using the Royer R-122V The following are good basic starting places for recording with the R-122V. These positions are known to produce good results, but experimentation is the key to getting the most out of your recordings! Photographs of many of the following techniques can be found at www.royerlabs.com. - Page 14 sound. Basically, what you hear at the amp is what you get in the control room and in your recordings. Choirs and Orchestras can be picked up well using a pair of R-122V's. Place the microphones at a height of ten feet or so and a few feet behind the conductor. The microphones should be spaced apart approximately one foot and angled, one toward the left and one toward the right, or in the classic Blumlein configuration.

Page 16: Stereophonic Microphone Techniques
Stereophonic Microphone Techniques Classic Blumlein Technique For many years, several “coincident” microphone setups have been widely used for picking up sounds in stereo as naturally as possible. Figure 1 Classic Blumlein or coincident miking technique The “Blumlein” technique, named for A.D. Blumlein of England, involves the use of two figure- eight microphones positioned as in the sketch (see Figure 1), so that one faces left and the other right, at an angle of 90 degrees (i.e. -

Figure 3 Typical M-S connection set-up figure-8 microphone, the front side of the R-122V is in-phase and the back side is out-of-phase. We suggest that you reverse the phase polarity on your microphone preamplifier to achieve in- phase recordings when tracking on the back side of an R-122V. Normal proximity effect (increase of bass), which is prevalent on the R-122V and all ribbon microphones, starts to occur normally at 4-6 feet from the microphone and increases with closeness. - Page 19 2. Do not expose the microphone to direct blasts of air or strong air currents! Use a windscreen or suitable pop filter when close miking a vocalist or certain types of wind instruments. P- popping does not necessarily damage the ribbon element but may produce unacceptable preamplifier overload and could cause damage to speaker systems.
