The LP (from long playing [2] or long play) is an analog sound storage medium, specifically a phonograph record format characterized by: a speed of 33 + 1 ⁄ 3 rpm; a 12- or 10-inch (30- or 25-cm) diameter; use of the "microgroove" groove specification; and a vinyl (a copolymer of vinyl chloride acetate) composition disk.
On civil turbofans, the first stage of the LP compressor is often a single-stage fan. If the HP compressor pressure ratio exceeds about 4.5:1, then the unit will probably have variable geometry (i.e. variable stators) on the first few stages, to make the surge line on the compressor map more shallow, to accommodate the shallow working line.
Its name is derived from the 12" vinyl LP (long play gramophone record). Hi-Fi Choice reviewers voted the LP12 "the most important hi-fi component ever sold in the UK" [2] and The Absolute Sound ranked it the second most significant turntable of all time in 2011. [3] Linn named their flagship CD player the Sondek CD12. [4]
Highway Hi-Fi was a system of proprietary players and seven-inch phonograph records with standard LP center holes designed for use in automobiles. Designed and developed by Peter Goldmark, [1] who also developed the LP microgroove, the discs utilized 135 grams of vinyl each, enough to press a standard 10-inch LP (12-inch LPs of the period commonly used 160 grams of vinyl each and 45s used ...
Three vinyl records of different formats, from left to right: a 12 inch LP, a 10 inch LP, a 7 inch single. A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove.
Acoustic impedance, denoted Z and measured in Pa·m −3 ·s in SI units, is defined by [2] = ^ ^ (), where ^ is the Laplace transform of sound pressure, [citation needed] ^ is the Laplace transform of sound volume flow rate.
The Gallardo LP 560-4 Gold Edition (金色限量版) is a limited (10 units) version of the Gallardo LP 560-4 for the Chinese market, with gold body color, black engine cover frame, LED headlamps, Cordelia glossy wheels, red brake calipers, black interior, red stitching and embroidery at steering wheel and headrest.
However, an Instagram page known as "@murcielagosv.registry" has been tracking the exact number of LP 670-4s and as of 2023 there have been 261 units found so far. The initial plan of 350 units was scrapped due to the factory requiring to make room for the Aventador's assembly line which is the Murcielago's successor.
