The R-101 is a handcrafted precision instrument capable of delivering superior sound quality and exceptional performance. This operator’s manual describes the R-101, its function and method of use. It also describes the care and maintenance required to ensure proper operation and long service life. The user guide section of this manual offers practical information that is designed to maximize the performance capabilities of this microphone. Royer Labs products are manufactured to the highest industrial standards using only the finest materials obtainable. Your model R-101 went though extensive quality control checks before leaving the factory. Normal care is all that is required to assure a lifetime of trouble-free service. Please read the manual thoroughly in order to become familiar with all of the R-101’s capabilities. It will assist you in making the most of your microphone’s superior acoustic properties. This owner’s manual is a handy reference guide and we suggest you refer to it whenever questions arise on the use and care of your R-101 ribbon microphone. Description The R-101 is a bi-directional (figure-eight) velocity type ribbon microphone designed for professional applications. The figure-eight pick-up pattern allows the R-101 to be addressed from either side with equal sensitivity. The in-phase signal is achieved when the microphone is addressed from the front, indicated by the “ROYER” logo. The R-101 is reasonably tolerant to shock and vibration, and performance is unaffected by changes in temperature or humidity. However, ribbon microphones are somewhat more sensitive to direct blasts of air, and the R-101 is no exception to this rule. Discretionary use of a windscreen or pop screen, such as the Royer PS-101, or equivalent, is highly recommended for close-miking vocalists or certain types of percussion and wind instruments. Applications The Royer Labs model R-101 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. Its gentle low-frequency proximity effect makes it especially useful for announcers and vocalists. Female vocalists often benefit from the R-101’s ability to capture high frequencies without distortion or edginess. Orchestral instruments are captured in a natural-sounding way and free from microphone-induced hype. The R-101 has exceptionally smooth high frequency 3 characteristics. Phase-related distortion and irregular frequency peaks are conspicuously absent. Electric guitar amplifiers sound big and natural, without unnatural coloration, when reproduced with the R-101. The R-101 ribbon microphone is an ideal choice for strings, woodwinds, percussion, organ and amplified instruments. Acoustic pianos can be captured accurately without the comb filtering effects associated with condenser microphones. Ribbons in the Digital World Digital recordings benefit greatly from the properties inherent in ribbon microphones. Since A to D converters cannot distinguish between the sound source being recorded and the complex distortion components often associated with condenser microphones, they sometimes have difficulty tracking the signal, resulting in ringing and edgy-sounding tracks. With ribbon microphones, ringing is almost nonexistent due to the ribbon’s lack of distortion artifacts and high frequency peaks. A to D converters have less difficulty tracking the ribbon-generated signal, resulting in very smooth digital recordings free of microphone-related edginess. User Guide Using the R-101 Ribbon Microphone There are a few important facts about ribbon microphones that are key in understanding how to use them intelligently. 1. The R-101 is a side address, bi-directional microphone and its rejection in the dead areas is very strong. Due to this directionality, the R-101 should be placed at 1.3 times the distance normally used with omni-directional microphones, or about the same distance used for cardioid microphones. This method is used to achieve the same ratio of direct to reflected sound. 2. In the horizontal plane, the R-101 does not discriminate against the highs off axis; nor does it boost highs on axis. Therefore, several instruments or vocalists can be placed in front of the microphone without favoring the performer in the center of the group. Several performers can be grouped at both the front and back of the microphone, with one proviso: since the outputs are out of phase at the front and back of the microphone, cancellation can result if, for example, two tenors are placed at opposite sides at equal distances and they are singing in unison, so listen to the feed before committing to it. 3. When using the R-101 to record loud signal sources, placing the microphone slightly off axis to the signal source (either horizontally or vertically) minimizes the effect of high pressure sound levels displacing and possibly damaging the ribbon element. 4 4. The R-101 requires no power supply and is safe to use on consoles with phantom microphone powering, provided that the cabling is wired properly. It should be noted that not all ribbon microphones are compatible with phantom-powered systems, so check the manufacturer’s recommendations before using other ribbon microphones. It should also be noted that faulty or improperly wired cables could cause problems with your R-101. Do not patch an R-101 through the mic tie lines of a patch bay if phantom power is enabled on any of your mic pre’s, as this will give the ribbon element a brief but damaging phantom power jolt. 5. Never attempt to test the R-101 or any ribbon microphone with an ohmmeter. A blown ribbon could result. 6. Always provide adequate protection for your R-101, or any ribbon microphone. If the microphone is to remain set up on a stand when not in use, place a 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. 7. Do not allow the microphone to be dropped on hard surfaces such as floors or tables - depending on how the mic falls, you could stretch the ribbon. The microphone would likely continue to operate, but performance could be compromised and re-ribboning the microphone would be necessary to restore normal operation. Amplification Considerations The performance of any non-active ribbon microphone is directly affected by the microphone preamplifier it is paired with. With so many mic preamps on the market, how do you select one that gives the best possible performance with a ribbon microphone? Additionally, what kind of performance can you expect from the preamplifiers built into your mixing desk? While most preamplifiers will handle ribbon microphones well in most recording situations, some preamps that work perfectly well with condenser or dynamic mics may prove to be poor performers with ribbons. To begin, we must understand the fundamental differences between ribbon microphones and other popular types, namely condenser and moving coil dynamics. A ribbon microphone is actually a dynamic microphone that uses a corrugated, extremely low mass ribbon element, rather than a coil/diaphragm assembly. For this writing, any mention of dynamic microphones will relate to moving coil dynamics. All condenser microphones have a built-in preamplifier called a head amp, and therefore put out a hefty signal. Because the signal is buffered through the head amp, the output impedance is rather low and less affected by the input impedance of the microphone preamp. Most dynamic (moving coil) microphones generate a healthy enough electrical current to work well with a 5 variety of preamps, and their limited frequency response characteristics make mic loading less of a concern. Ribbon microphones generate a highly accurate signal, but the average ribbon mic generates approximately 20dB less output than condenser microphones. Remember, the ribbon transducer does not have the benefit of a condenser mic’s built-in “head amp,” so a non-powered ribbon microphone relies solely on the microphone preamp for all its gain! The so-called ideal preamplifier is the proverbial “straight wire with gain.” This may be considered the technological ideal and does not include coloration as a desirable feature. However, coloration is often desirable and has given rise to the popularity of certain preamps and even preamp stages in mixing uploads/Management/ guide - 2023-05-30T063554.795.pdf
