and compacts a portable usually consists of a turntable and two Small speakers which fold up into a carry Able with a Price Range from about to the portable will produce Good enough music for the untrained but it int if you can afford a Little More and care if your system is a Little less into a compact transistor circuits have made it possible to Combine a fairly powerful record changer and in some cases an pm tuner or tape Cartridge player All in a single unit of modest some come with relieving the Novice buyer of the decision of having to buy his one drawback with the compact is you cant choose your components the amplifier might he the speakers Yon cant replace or one part of your system a and if one part goes wrong the whole system goes to the no one pretends that he offers the finest performance rut with prices ranging from about to More than there is Little doubt thai the compact system offers a justifiable Compromise for someone not ready to plunge into components this is what the real audiophiles Are talking what do we mean when we refer to components such a system involves several separate a Power source the amplifier the speakers and the musical program sources record pm Andor am tuner or tape components Are remarkably versatile they can be scattered attractively on shelves or can he installed in a custom Wall or Cabinet amplifier in the Early Days of audiophiles usually had a Power amplifier and a separate or control these usually Are included in what is called an integrated the key thing to pay attention to when buying an amplifier is the More the better the ability to capture the Hirth and Low ends of the musical spectrum with the least distortion and thus better there Are two ways to rate amplifier Power Good and the bad Way is to Tell the Peak a measurement of the maximum output at the instant of a Strong passage of the fact that there Are Many ways to measure this output is indicated in the different names for such a rating music

since the greater the Ohms the less Power the amplifier is Able to he sure you know the Power rating in relation to the impedance of the speakers you will be prices for amplifiers Range from about for an amplifier rated at 15 to 25 continuous Watts per Channel into 8ohm speakers to More than for the new Breed of 350watt a Good Compromise would he 40 or 50 Watts per Channel for about receivers a receiver consists of an amplifier and a radio tuner pm or both in the Samp the drawbacks Are pretty much the same As those for the while receivers Cost less than separate components and Are easier to there Are some who argue manufacturers skimp on the amplifier in but an audio technician recently told me this is whatever the the receiver is the fastest growing component with each manufacturer hav ing at least five or six for Between and you can expect to get 15 to 25 Watts per Channel adequate to drive most for music the models at about should provide the most performance for the Money 30 to 50 Over youre getting into personal As features tend to overlap in different Price tuner the tuner is fancy radio which on pm can a stereo specifications to look for when shopping or ability to pull in signals Micro volts is about the capture or ability to respond to Only the stronger of two signals on the same frequency one Decibel is about the the lower the prices Range from about to a very Good tuner can be had for speakers there is an exception to every and speakers Are it there appears to be no particular correlation Between the Price of a speaker and its All you really have to go on Are your own so when a Good speakers response should be the following untrained Low even distribution of Midland High Range tones throughout the smooth no dips or peaks in the frequency if a speaker thumps or booms when reproducing the male it probably has a Peak in the upper base Woofer this could be affected by acoustics in the listen ing so also listen to it in if a speakers mid Range is it May sound strident or perhaps merely Bright or mildly a Good Way to test for High frequency Tweeter response is to play music that includes triangles or listening quadra sonics War has Many Heads spinning at 78 rpm if you thought the Battle Between 45 rpm and 33 rpm records was you been paying attention to the quadra sonics is quadra sonics a it is a step further than stereo two speakers set apart in front of the listener like and two behind him creating a surround sound that is said to be As much an improvement from Stere phonies As stereo was from added to the con fusion of three competing tape formats open cassette and eight track there is the chaos of the quadra sonic with four Channel formats being proposed not Only for the three non compatible tape hut in non compatible

by mix ing then unscrambling them into four channels with a proper a lot of these systems have been probably be cause the decoders give a sound to Ordinary stereo Roth these systems Are having their one of the main drawbacks being that so far the selection of four Channel discs or pre recorded tapes is the big is what will this mean to the stereo for those planning on buying new there is no reason for not buying one of the new four Channel amplifiers or re except it will he More and it May be a while before you get full use out of if you already own stereo there is no heed to Trade it As it will not become to convert to Yon would need two More speakers and another amplifier for two More channels this have to be an integrated amplifier with full controls an Ordinary Power amplifier
