What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Hitachi SR-802

 "Our SR 802 tuner amplifier will set you back over £200.
You could pay more, and you could pay a lt less .
But cheap alternatives have a nasty habit of giving up when  he going gets hot."

We guarantee this won't happen with a SR 802. It's got a built-in protection circuit tolook after your power transistors and speakers.
At the first sign of trouble it'll turn itself off.
And there's warning light on the front panel to keep you in the picture.
The tuner on the SR802 has some useful refinements too. Like the FM 'muting' circuit which eliminates all inter-station noise is being selected.  And there's one more feature on the SR 802 you won't find on every turner amp.
It's called reliability. And it's standard on all Hitachi equipment.
So is the Hitachi 2-year guarantee.
