Good copy and great customer service! There was some confusion with my order and it was resolved promptly!

Having bought a pre-owned Sony FM stereo tuner through eBay, it came without any manuals. It soon became clear that to get the best from this excellent tuner I needed a decent manual because much of the operation was not intuitive to a newboy to hi fi like me. I managed to download the official Sony multi-lingual manual from Owner-Manuals.com with no problem at all - a really quick and easy service. I'm very glad I did because I found out all the operations of the tuner and was then able to not only set it up quickly but also to get much more from it that poke-and-hope trialling would ever achieve. In my book $4.99 very well spent.

This manual is immaculate in it's accuracy. Everything is written very clearly and easy to understand. Written by a professional who wants to convey a clear and easy to understand message!!
OHM�S LAW AND THE HOT SPOT
Most professional-type speakers (like the HOT SPOT) have two jacks which are wired in parallel (meaning the signal can travel into one jack and out of the other). Think of each speaker as a �load� added to the amplifier. The greater the number of speakers, the heavier the load. Adding too many speakers can overload the amplifier, causing it to overheat and distort. If the amplifier begins to distort, or if it becomes hot to the touch, disconnect any extra speakers. One easy way to determine the load on the amplifier is to use Ohm�s law, which states: �The total impedance of N speakers in parallel is equal to the reciprocal of the sum of the reciprocals. In equation form:
Z (Total) =
1 Z1 +
1 Z2 +
1 1 Z3 +
1 Z4 +
1 ZN
Where Z1 is the impedance (or ohm rating) for the first speaker, Z2 for the second, and so on, for every speaker in the chain. This equation calculates the total impedance of the speaker system, which should NOT be lower than the minimum impedance rating of the amplifier. EXAMPLE 1: For one pair of speakers use the short form of the equation: the product of the two speakers divided by the sum of the two speakers is equal to the total impedance or the equivalent impedance of the speaker system.
Z=
Z1 x Z2 Z1 + Z2
This equation may be used to calculate the equivalent impedance for additional speakers in two-speaker increments. Determine the impedance of the first two speakers, substitute Z total for Z , and include the next speaker. Repeat the process until all speakers have been included. The result should be the same as with the first method. A word of caution: polarity rules must be observed when connecting multiple speakers. Polarity will not affect the Z, but can affect the quality and volume of the sound. If you are having problems with any of these applications use Galaxy Audio�s CRICKET Polarity and Continuity Test Set to check the polarity of your cables.
