Add to Product List. It is the large-diaphragm … The result is a higher sensitivity of 10 dB for identical sound pressure levels, and an improved signal-to-noise ratio of 3 dB. The U 87 Ai is used as a main microphone for orchestra recordings, as a spot mic for single instruments, and extensively as a vocal microphone for all types of music and speech. This is still lower than Rode K2’s maximum SPL handling. Four versions of the U87 were initially released by Neumann: According to Klaus Heyne, over 20 variants of the U87(i) circuit were created by Neumann. Hopefully nothing will have popped or made a burnt smell! The body of the U87(i) housed an optional pair of 22.5V batteries. On the other hand, Neumann U87 requires +48V phantom power. The U 87 A, on the other hand, which had its own DC-DC converter, uses the K67 capsule, now named K870/67. This is a way of powering condenser microphones from the microphone input. By means of a high-pass filter, interferences through subsonic and low frequencies are reduced remarkably. Used for overheads, string instruments, piano, guitar cabinets, singing, and of course, voice-overs as well, the U87 is one of the most versatile microphones on the market. Curiously, some of the very early U87 microphones even lacked a battery compartment. The U87 was released at a time when phantom power was being used in microphone design and manufacturing. The K103 is based on the K87, the dual-diaphragm capsule found in the classic U87 and U67 Neumann microphones. Also, phantom power does not affect dynamic microphones that do not require external power. The nickel U 87 Ai Condenser Microphone from Neumann is a large dual-diaphragm condenser microphone. Only Neumann U87 Ai sounds like U87 Ai. A Note to StudentsThe city of Berlin, which has been home to Neumann for over 75 years, has been subjected to tremendous upheaval since the fall of the Berlin Wall. Neumann produced two transistorized versions of the U 67: from 1967 to 1986, the phantom-powered U 87, and from 1968 to 1974, the AB-powered U 77. “By 1986, however,” as Stephan Peus relates, “these batteries were no longer obtainable and the battery compartment became otiose, so we decided to use it to accommodate a DC-DC converter of the kind used by the U 77 and therefore capable of delivering exactly 60 volts to the capsule. The Shockmount includes a windscreen, cable, EA87 elastic suspension and comes in a wooden jeweler's box. The U87 AI eventually replaced the 48V phantom power with a DC-DC converter, which led to a change in the microphone’s sensitivity and signal-to-noise ratio. DescriptionThe U 87 is probably the best known and most widely used Neumann studio micro­phone. My first U87, which I still own, was made in 1967. U87AIMTSTUDIO £ 1,979.17 Price excludes VAT. Since 1967, the Neumann U87 has been one of the most popular vocal microphones available. This revised capsule was called the K87. The mic’s capsule, called the K87, was a center-terminated, dual-backplate, dual-diaphragm 34mm design, like the K67. From the eBay seller’s description: “This is the original Neumann U87, serial number 21773. In 1980, a slightly smaller version of the U 87 was launched: the U 89, which was handier and lighter. Free P&P. Like many microphones, the U87 runs on 48-volt phantom power supplied by an XLR connector. or Best Offer . KMA (1968) Clip-on Microphone. NOS SIEMENS EC92 6AB4 for NEUMANN UM57 UM92 … I dont have an outboard console so I cant combine signals. Das Brauner klingt etwas … Hear a voice recording made with this mic. The original U87 used the 48V phantom power supply to polarise the capsule directly, and as a consequence, the electrical design of the capsule had to be modified slightly compared with that of the U67, to isolate the front and rear backplates. Acoustic FeaturesThe U 87 is addressed from the front, marked with the Neumann logo. To verify that a mixer or preamplifier provides phantom power, voltage measurements taken between pin-2 and pin-1, and pin-3 and pin-1 will read identical levels. Both models were equipped with a battery compartment, which, in the case of the U 77, accepted one 9-volt battery, and in the case of the U 87, two 22.5-volt batteries of the type at the time used by photographic flash guns. While a successor to the U87, the large diaphragm U87 AI is a fantastic mic all on its own. Once connected switch the preamp ON and then switch phantom power ON. Microphone Neumann Gefell parts. Set to P48, all conventional microphones can be used as well. Last one. A 10 dB attenuation switch is located on the rear. It differed from the K67 in three acoustically-transparent respects: These changes were required to support the Figure-8 polar pattern, which otherwise would have required more power than the 48V phantom power supply could provide (without a DC-DC converter). A switch below the headbasket allowed selection of Cardioid, Omni, or Figure-8 patterns. Product lists can be submitted to HHB for a packaged quotation. It's been thoroughly tested and is in full working order. It is equipped with a large dual-diaphragm capsule with three directional patterns: omni-directional, cardioid and figure 8. Free shipping. Additional inputs for line … The preferred studio vocal mic for decades, the Neumann U87 also makes a great main mic for band or home studio recordings, as well as a spot mic for single instruments. Cek Harga. Engineers, producers, and their clients loved the U 87, and by the … You will need a mixer. Plug the microphone in to your preamp making sure phantom power is OFF. If there is a … Connect the microphone only to microphone in-puts … However, in the U87Ai a DC-to-DC converter was added, which allowed Neumann to revert to … The ‘A’ revision replaced the battery pack with a DC-DC converter, allowing the mic to generate the 60V that the K67 capsule was designed for. In the K87, the spacer is made of (non-conductive) plastic. ApplicationsThe U 87 Ai condenser microphone is a large diaphragm microphone with three polar patterns and a unique frequency and transient response characteristic. When operating on batteries, it can even feed an unbalanced mic input, such as on a cassette or portable digital recorder. The original Neumann U87 was polarized at about 46V due to a lack of DC-DC converter. Safety Using a suitable cable, connect the microphone instructions The microphone has the intended purpose of con-verting acoustic signals into electrical signals. This was the first version of the U87 which can operate on phantom power or from internal batteries. Why is the Neumann U87 … If there are no batteries installed, it runs on phantom power like any other condenser microphone.”.

The KM 86, however, was developed for P48 phantom power, introduced a few years earlier by Neumann – and soon the world standard. Neumann includes a cable in the box. I plugged both in, and, after adjusting for output differences, I could have easily used both as [a] pair in a critical stereo apllication. It replaces the U87’s 48V phantom power with a DC-DC converter, for one. A switch below the headbasket allowed selection of Cardioid, Omni, or Figure-8 patterns. Used on countless famous recordings for vocals, drums, guitars - anything you can think of in fact - the Neumann U87 is one of those mics that is simply ubiquitous. The mic used the new K87 capsule, which was sonically identical to the K67 capsule, but utilized phantom power instead of an external PSU. The beauty of this solution (a Neumann invention) is that it does not require any additional leads but uses normal XLR cables. The mic has a low impedance of 200 ohms and the maximum cable length is limited to 980 feet to avoid signal loss. The Neumann U87 Ai is the more modern version of a classic mic. Frequency range: 20Hz to 20kHz; impedance rated at 200 ohms. The capsule mounting screws were “sleeved” to prevent an electrical connection between backplate halves. In the 1960s, Neumann (being the crafty German audio geeks they are) found a way to power mics by transferring current through the mic’s cable straight from the mixing desk. Popular phantom voltages are 12 V, 15 V, 18 V, … In short, the U87 was a tripolar FET condenser with a transformer-coupled output. ables Neumann users worldwide to share their experiences.
