SPECIFICATIONS Frequency Response 40 Hz 20 kHz Type Electret condenser Directional Characteristics Omnidirectional Sensitivity 52 dBV 0 dB 1V microbar Maximum SPL 135 dB Impedance 250 ohms Case Brass Windscreen Chrome plated stainless steel wire mesh Dimensions 5 5 long x 865 diameter 14 cm 2 2 cm Weight 8 oz 135 grams Accessories Included Foam pop filter swivel adaptor lined metal storage case Connector XLR 3M Cables Required Low impedance operation Use standard two conductor with shield microphone cable with XLR 3 type connectors High impedance operation A standard XLR type microphone cable must be used between the microphone and an external phantom power supply A microphone cable with integral impedance converter should be used between the phantom supply output and a high impedance microphone input FEATURES Omnidirectional polar pattern e Smooth frequency response suitable for vocal or instrument applications Chrome plated stainless steel wire mesh windscreen Brass case Improved shock mounting No proximity effect PVR 1 Omnidirectional Microphone DESCRIPTION AND APPLICATIONS The PVR 1 microphone will maximize the fidelity of most any recording process It is capable of providing transparent signals in both the traditional live recording using a small number of microphones and in the contemporary studio recording using close microphone2. PVR 1 requires external phantom power to drive the electronics This microphone will not accommodate internal batteries Any mixer with phantom power or any outboard phantom supply in the range of 9 to 52 volts DC may be used The PVR 1 has an internal voltage regulation circuit that will see that the internal electronics receive the proper voltage even when used on higher voltage phantom power supplies 52 volts DC In absence of phantom power in your mixer we recommend the Peavey PS2B battery powered supply for two microphones or the PS 4AC AC powered supply for four microphones PLUGGING AND UNPLUGGING ELECTRETS When plugging electret condenser microphones into audio mixers it is advised that the channel gain be reduced to zero to eliminate the possibility of a transient thump The channel gain should also be reduced to zero when unplugging and when switching phantom power on or off Polar Pattern RESPONSE iN dB 20 50 100 200 10K 20K 5K 1K 2K FREQUENCY IN Hz
3. techniques The PVR 1 displays excellent transient response in addition to a broad bandwidth and smooth frequency response to assure the highest fidelity The PVR 1 utilizes a small condenser element diaphram to minimize diffraction in addition to minimizing the directionality of high frequency material High quality FET electronics have been incorporated to provide extremely low noise and sonic excellence in capturing even the most minute qualities in any given sound The low noise of the PVR 1 and its ability to capture high sound pressure levels without audible distortion provides exceptional dynamic range This allows the softest of pianissimos and the loudest of fortissimos to be captured by the PVR 1 making it an excellent choice for quality recording or sound reinforcement applications OMNIDIRECTIONAL PATTERN The PVR 1 microphone has an omnidirectional pickup pattern Omnidirectional microphones are equally sensitive from the front sides and rear This provides the microphone with the ability to pickup all sounds equally regardless of their orientation relative to the microphone It must be kept in mind that for recording studio purposes an omnidirectional microphone will pickup far more leakage In live performance or PA applications omni s are far more susceptible to acoustic feedback because of their non directionality When the PVR 1 is used to record acoustic instruments in the far field of an auditorium envi
4. ronment the natural room ambience is picked up so that the reproduced signal includes the subtle nuances of the room characteristics The microphone is small and unobtrusive which allows installation in most any environment where aesthetics are important The PVR 1 can also be used for studio type multi track recording in situations 7 3 om 15 32 7 8 5 4 5 32 where you desire no proximity effect This microphone will display the same frequency response characteristics in the near field close miked and in the far field distant miked without the normal increase in low frequency response that is contributed by cardioid type microphones ARCHITECTURAL SPECIFICATIONS The microphone shali be an electret condenser omnidirectional type with a uniform frequency response of 40 20 000 Hz The microphone shall have an output level of 52 dB 0 dB 1 V microbar The microphone will exhibit little if any off axis attenuation The microphone shall use a shock mounted electret condenser element that provides stability long life and high impact strength while having an output not appreciably affected by temperature and or humidity extremes from 18 80 C 0 F to 54 49 C 1300F The case finish of the microphone shall be brass and the finish shall be non reflecting black color paint Tne mic shall have a matte black head shaped to reduce sound diffraction shadowing to improve the omni pattern PHANTOM POWER The
