You can buy a separate automatic unit for less than $50 or pay over $500 for a mianual turatable equipped with. a precision rnagnetic pickup. AlIows ecreatiyity Tape systems geaerally have the advantage of ai- Iowing you to create as well as to en.'joy recorded souad. Like the other ýprograrn sources, they generate electricai signais for the amplifier. The amplifier is the heart of any home nusic system. It receives weak electricai signais fror t1he various program sources and boosts thern until they're strong enough Wo drive one or more loud- speakers. Amplifier poWer Amplifiers are rated in termas of the power they produce-the more power- f ui the amplifier, the more it's liikely to cost and the better its ability to handie loudmusical passages and produce rich, deep bass. Theend the music cornes out of is the loudspeaker- or more properly the ioud- speaker system. Tonal spectrurn The better stereo sys- tems use not one speaker for each channel, but two or more - usually of dif- ferent sizes and design - ~to specialize in different parts of the tonal spec- trum. You can find ail these parts in a basic sound sys- tern like a portable phono or buy them as senarate components. Before youi go shopping, decide not only how much you xant to spend, but what you expect in retura for it, la terms of prograzn sources, souad qualityand loobs- Total ýytem or tailored -Tou mnay buy them together as a total system pre- selected by the manufacturer or dealer, or pick out in- dividual components tailored to your own musical needs. Program sources include AM and FM radio, phono- graph records and magnetic tape. SYou rnay want a systern capable of reproducing al three types. What you should know about.. Wha~sin a wvatt ' ne of the first things you're likely to discover when you set out to buy a, home music system - whether it's a single- brand modular system, a stereo compact or console, or full-fiedged hi-fi coin- ponent system - is that mianufacturers rate the Power of their products in watts. And the number of watts you get is related directly Wo the price you pay., The Wattage power of the amplifier circuit is as much an index to the per- formance abiity of the systern as Ilsthe horsepow- er ratiag of a car, The trouble is, until, re- cently there were nearly as many systemas for rat- ing amplifier power as there were mnanufacturers produc;ing phonos and hi- fi compo1neats. So the Fed- erai 'lrade Commisýsion has corne up with a sys- tern for mueasuriag power which puts al manufac.- turers and ail types of home entertalrneat prod- ucts on anequal footing - the "RMS", ratiag system. The FTC system makes sure ail wattage compari- sons use the samne stand- ards. So. when you see tWýo hi-fi components with dif- ferent RMS ratings, you-- can be sure they were test- ed under equ al conditions.
