GIVE ’EM A Not too many (any?) hifi systems these days come with a record turntable. So what do you do with that collection that’s been gathering dust since your old faithful died? There’s plenty of turntables out there! Just dip into our listing. by BARRIE SMITH I f you had any doubts about the future of LP recordings just walk around your local hifi store and see the bins full of LP reissues and even some new titles. And they’re not cheap either, with prices frequently level with and sometimes above new CDs. Maybe you want to wrap your tone arm around the Buddy Holly LP, “pressed on 180 grams of virgin vinyl, remastered from the original tapes without compression!” Just $48 for a singe disc. Of course, the happy hunting grounds for vinyl platters with a bit of age on them are the charity shops, garage sales and school/church fetes. Plenty of people these days are spending the odd hour or spare day converting their vinyl to CD or MPS tracks for use in iPods and similar. With the right software you can bring analog recordings back to original quality: no clicks, bumps, pops. You need a turntable. There are a few options: you may have no desire to mix it with eBay to grab a preloved turntable from a seller that probably matches the age of your LP collection. If you’re in need of some turntables or other components of a ‘certain age’ you will be surprised at how easy and economical they are to acquire these days. Aside from checking around with friends (especially 16  Silicon Chip the spouses or partners thereof!) to prise some unwanted hardware from their hesitant fingers, the next stop should be the used section of hifi retailers. But you may find the occasional absence of manuals with used equipment a bit of a bind! I regularly haunt Len Wallis’ premises in Sydney; the pre-owned amps, turntables and tape machines are a joy to behold, in excellent working order and very fairly priced. Other cities have similar businesses you can scour. But if you prefer not to mess with gear of an indeterminate age and go the new route, there is a virtual forest of new models out there from prestige manufacturers, as well as the majors like Sony and Panasonic. New turntables can vary enormously in price, comparable in the range from a second hand Datsun 120Y to a new Merc 200; I’m talking in a range from $400 to $68,000! This turntable listing includes units priced below $2000. There are others … but if you’re spending in the tens of thousands of dollars for a turntable to retrieve the sonic glories of yesterday you either need your head read — or you should get out more! (BTW: the abbreviation MM in the listing stands for moving magnet cartridge.) siliconchip.com.au SPIN! Buying a turntable The argument continues: is the reproduction of sound from an analog LP superior to that from a digital CD? I’m not buying into it other than to say I personally don’t miss the clicks and bumps from a vinyl LP and I do find the quality on the best of CDs far superior to that of top LPs. So there. But if you want to copy your LP collection to CD and you’ve dumped the family record player years ago there is no alternative: you will be buying a new or second hand turntable. Basic turntable construction is just that: pretty basic. In the main case there is a motor, a drive system which connects the motor to the platter so that it rotates at the appropriate speed and usually (though not always) some method of selecting that speed. Alongside the platter (which itself rotates the records) is a tone arm which moves over the surface of the record. It carries the cartridge which converts into electrical signals the miniscule movement of the stylus as it tracks the record’s groove and vibrates from side to side in accordance with what was recorded in that groove. There is usually some method of adjusting the downward force the stylus exerts on the record. siliconchip.com.au The best turntable systems can reduce the clicks and other noise from the record surface while inferior turntables may well exacerbate this. Speeds 33-1/3 RPM (revolutions per minute), 45 RPM and the lesser seen (older) 78 RPM are the main ones you will encounter. Let’s hope you’re not confronted by 16-2/3 RPM discs; many older turntables do not handle th is speed! Before investing in a turntable, check to see if your amplifier or receiver has “phono” inputs. These are inputs with (a) the appropriate sensitivity (usually around 5-10mV); (b) the appropriate input impedance (around 50kW) and (c) most importantly, response tailored to reverse the equalisation which is applied to records in the manufacturing stage. If your amplifier or receiver doesn’t have such an input, you will have to buy a turntable with inbuilt preamp or buy/ build a separate preamp to connect between the turntable and your amp/receiver. The output from such a preamp (or preamp-equipped turntable) can be fed directly into the sound input of your computer for dubbing onto the final CD. Many computers only have “mic” inputs – use this in the absence of a “line in” input and reduce the gain. May 2007  17 Recorded Sound Progress A successful and commercially viable method of recording and reproducing sound was long in coming but it was not until 1948 and the arrival of the 12 inch 33-1/3 RPM vinyl LP that music quality began to approach that of the original performance. The earliest recorded sound system dates back to circa 1500 BC. The mammoth “vocal” statue of Memnon at Thebes had the ability to make the sound of a harp string every day. The early 16th century saw the appearance of barrel organs, using rotating cylinders and attached pins, driven by clockwork gears that reproduced sound. Jacquard’s punched card system, initially devised to weave fabrics in the early 1800s, became the basis of an organ driven by bellows, pumping air jets through the card holes to create music. The approach was similar to the player piano and paper rolls that many of us grew up with. Edouard-Leon Scott de Martinville in Paris made a Berliner Gramophone “phonautograph” in 1857 to trace of 1888waves onto a carbonised cylinder with a stylus attached sound to a diaphragm that vibrated from spoken sounds. The device did not record the sound, only a graphical image of sound. In 1877 Charles Cros described a phonograph device but never built a model. Edison was seeking to improve the telephone in 1877 when he discovered the recording device known as the phonograph. In the same year Edison recorded a human voice speaking “Mary had a little lamb” onto the first phonograph using a tinfoil cylinder. Playing time was about 2-3 minutes. Early materials used for the cylinders were lead and wax. The Graphophone (as distinct from Gramophone) was patented in 1885, using wax-coated cylinders incised with vertical-cut grooves. Emil Berliner was first with a phonograph — the gramophone — in 1887 that used a flat disc, a non-wax disc engraved with a lateral-cut groove. The 7-inch (17.5cm) disc was hand-cranked at 30 RPM with a two minute playing time. Berliner was the first to mass-produce hard rubber vulcanite copies from a zinc master disc. He later used shellac, which was used later in pressing the popular 78 RPM records that were displaced by vinyl LPs only in 1948. The early steel styluses tracked at a weight of nine ounces (255 grams). Magnetic recorders came along in 1898, patented by Valdemar Poulsen using steel wire. Wire recorders were still in use by Australian radio Edison tinfoil phonograph 18  Silicon Chip stations in the 1950s. Double-sided flat discs were first sold in the early 1900s. HMV marketed a complete opera on 40 single-sided discs. The Odeon company competed with the Nutcracker Suite on four double-sided discs. Edison fought back in 1912 with blue celluloid cylinders that played for four minutes. Played with a diamond stylus, the new cylinder had low surface noise that gave better quality than flat discs of the period. However Thomas Alva finally conceded victory to the flat disc and began to use discs with a surface of plastic, laminated to a 1/4 inch thickness, similar to Bakelite. The bane of careful record collectors was the automatic record changer. The average gramophone, loaded with a dozen LPs could be guaranteed to destroy the audio quality on those hapless discs in doublequick time. The world’s first automatic record Berliner hand Gramophone changer was invented by Tasmanian Eric Waterworth, who showed it first at the 1927 Sydney Home Show. Due to a series of events Waterworth did not profit from the device, the patents lapsed and a number of English companies manufactured record-changing gramophones with almost all of them using the stepped centre spindle — a central feature of Waterworth’s design (information from SPAT). Vinyl discs were first used in 1929 when RCA began making transcription discs from optical movie soundtracks for radio stations to play on air. The same year saw the final production run of Ed ison cylinders and discs. In 1930, RCA Victor launched the first commerciallyavailable vinyl long-playing record, marketed as “Program Transcription” discs. These revolutionary discs were designed for playback at 33 RPM and pressed on a 30cmdiameter flexible plastic disc Many 78s were not recorded at exactly 78 RPM: speeds of between 72 and 85 RPM were quite common. A standard speed was not decided upon until around 1930. Up until then, record and replay speeds were pretty much subject to the left to the fancy of the various record companies; in fact, speeds ranged anywhere from 60 to 130 RPM. The majority of records, as it worked out, played quite successfully at speeds that ran from 72 to 82 RPM. Some examples: Edison and Diamond Discs siliconchip.com.au siliconchip.com.au May 2007  19 play at 80 RPM. Early Pathé discs run at 100 RPM. It was rare that a ‘78 RPM’ record actually played at a true 78 RPM. All of these will track happily at 4-5 grams, the optimum weight given the groove-wall geometry/dynamics of the 78. The first magnetic tape recorder was built in Germany by Dr. Fritz Pfleumer and AEG/Telefunken in 1931; BASF/AEG made the tape. This recorder was publicly demonstrated in Berlin in 1935. This invention became the foundation of the US Ampex corporation (see Ampex and Germany). Ampex got a leg up thanks to an enterprising US engineer and the end of WW2. (See AMPEX and Germany). 1948: Columbia introduced the first 12-inch 33-1/3 RPM micro-groove LP vinyl record with 23 minutes per side capacity. Tracking weights of 5-8 grams were common. 1949: RCA Victor introduced the 7 inch 45 RPM micro-groove “Extended Play” vinylite record and player. 1953: Elvis Presley made his first recording on disc at the Sun Studio of Sam Phillips in Memphis; the second recording by Elvis at Sun a year later was taped on two Ampex 350 recorders. 1956: the Chrysler Imperial 16-2/3 RPM record player with 7-inch ultra microgroove records appeared. 1958: world standard for stereo records estabRCA Victor Phonograph lished and first stereo LPs sold. 1963: Philips demonstrated its first compact audio cassette Columbia using Graphophone high quality BASF polyester 1/8 inch tape that ran at 1-7/8 inches/second. 1966: US cars were equipped with 8-track stereo cartridge tape players made by the Lear Jet Corporation. 1969: Dolby Noise Reduction introduced. 1971: quadraphonic records were announced, recording four separate sound signals. This was achieved on the two stereo channels by electronic matrixing, where the additional channels were combined into the main signal. 1982: first digital audio 12.5cm CD discs marketed by Sony and Philips. The maximum playing time would be 74 minutes, long enough to hold Beethoven’s 9th Symphony. 1987: Digital Audio Tape (DAT) players introduced. It was recently announced that production of DAT recorders is to end. 1999: Sony and Philips launch Super Audio CDs (SACD) delivering two channel stereo and (optionally) a 5.1 channel surround mix. 2000: DVD-Audio discs appeared, offering reproduction of up to 7.1 channels. 2001: Apple’s iPod, using a minuscule internal hard drive, is on the market.

Take a look at www.copyright.org.au and see if the situation worries you enough to deter you from copying your old analog material – in fact, copying any material. In the US the copyright laws permit the making of one copy of an original for personal use. In Australia no such provision exists. Here it is illegal to make any type of copy of recorded music without the permission of the copyright owner – and that permission is rarely, if ever, given – especially without paying some form of licence fee. The key points: • There is no general right for individuals to copy recorded music, even from a record or CD you own and even if you want to use it on another form of “player” (eg, copying to an MP3 player or, as we are discussing here, copying old records to CDs). • There is no general right to copy copyright material for personal use under Australian law. • Ownership of a physical item (such as a CD) does not give you the right to make copies (including copying into a digital or other format). • There is no general right to copy recorded music from the internet without the copyright owners’ permission. The reality is that thousands of people make copies of records and CDs for personal use every day of the year. In moral and legal terms, it would be foolish to make copies for resale – or for gift-giving to another person. Much more information awaits at www.copyright.org. au/PDF/InfoSheets/G070.pdf May 2007  23 Turntable with USB output An easier approach could be the ION ITT USB Turntable, the world’s first USB turntable. It allows you to convert a vinyl collection directly to CD or (even MP3) with the included recording software. It is a ‘must have’ for people who don’t want to deal with clumsy adapters or mismatched audio formats. The ION USB turntable includes Audacity software for Win/Mac for recording as well as a trial of Bias Soundsoap 2 for cleaning and restoring LPs. If you’ve got a stack of old 45s, 33s or even 78s, you can now convert them to digital with this belt drive turntable. As well as the USB output it has a line level output for connecting to any home stereo with CD or auxiliary (AUX) inputs, via the stereo RCA outputs; it also has a 3.5mm stereo input so you can take a feed from a stereo cassette machine. It is compatible with any software that supports USB audio input sound cards so you can convert your vinyl into WAV, WMV, AIFF and MP3s. Includes a USB cable and pre-mounted cartridge with stylus and adjustable anti-skating control; a 45 RPM disc adaptor is in the kit. The turntable weighs 6 kg. While the turntable has only 33-1/3 and 45 RM speeds the included software can be used to convert 33-1/3 RPM transfers to 78 RPM. Another trick: replay 33-1/3 RPM discs at 45 RP for the dub: whilst saving time, these speed conversions possibly compromises the quality. In the case of the 78 RPM trick, the LP stylus is certainly the wrong profile for the old 78 shellac grooves. System requirements: Windows 98, 2000, or XP; Mac running OS9 or greater including Mac Universal. Price: $349.00 1300 761 466 www.techtoolsoftware.com Do it once. Do it right.

Fully automatic Automatic charge control, continuously monitors battery status as it powers your electrical equipment. If the battery’s voltage sinks below the level pre-programmed by the user, the fuel cell activates, charges the battery, and then automatically shuts itself off. And it does so without any user intervention. Remote Control Each fuel cell can be connected by an interface adapter to any RS232 interface and serviced/monitored using a cellphone, laptop or PC from the office. Theft Proof Solar cells need to be placed out in the open where it is difficult to protect them against theft and vandalism. The compact fuel cell can be integrated into any standard cabinet or box. More Power With the control interface you can operate up to 5 fuel cells in parallel, giving you a capacity of up to 8000Wh per day.

South Guildford email sales<at>elan.com.au www.elan.com.au Western Australia 6055 Cleaning Possibly the most critical factor in getting the best out of early analog recordings – especially disc, to a lesser degree tape – is getting rid of the cause of a lot of the noise and other garbage from the record surface: dust. And that means cleaning both the media and the machines that play them. In the heyday of vinyl records, no self-respecting audiophile would put a disc on the turntable without ensuring both were clean: the turntable platter with a dust brush and the disc itself with one of a variety of dust collectors designed for the purpose. Such things are still available today but you may have to search for them! For really dirty recordings, by all means use appropriate methods to clean vinyls and tapes but watch out for shellac or acetate records – alcohol will destroy these – so use water-based compounds. First of all, clean the mat of your turntable. If a “78” is cracked at the edges, avoid wetting it with anything: some 78s have a centre of fibrous material which expands when wet and shatters the record. Vinyls can be safely cleaned with distilled water, although grime will possibly be removed only by the use of proprietary fluids. A whole list of excellent cleaning approaches can be accessed at Decibel Hi Fi (www.decibelhifi.com.au). Or you can go to www.screensound.gov.au and follow the “Preservation” link. 26  Silicon Chip 33-1/3, 45, 78 RPM, and 9 other speeds for vintage discs and half speed mastering, DC motor, belt drive, electronic power supply, Delrin platter, audiophile quality tone arm.
