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.

Aiwa AD-6700

 The revolutionary new cassette deck designed to realize all the potential sound improvement that metal-particle tape can offer; the new Aiwa AD-6700. with the impressively broader frequency response and increased dynamic range that rival even today's most advanced reel-to-reels.
Aiwa designed it that way to make a breathtaking difference in the way you listen. There's Sndust Guard Head with extended 1,3 micron gap for optimum recording. Aiwa's double-gap Ferrite rease head and an improved rease circuit to meet the increased power demands of metal-particle tape.
But the extraordinary performance of the Aiwa AD-6700 doesn't stop with just metal-particle tape. Aiwa's own precision Bias Fine Adjustment System lets you select the proper bias for every tape formulation available today with just a twist of the dial. So every tape you play gives a flat response.
 The Aiwa AD-6700 makes distortion-free recording a cinch, with an amazingly accurate system of sensitive LEDs that instantly responded to peak signal levels. Aiwa's system boasts a highly visible three color display to help you record a safe level every time. A Peak Hold facility is also included.
For carefree listening, there's a convenient Auto/Repeat with Memory Switch that lets you replay the complete side of a tape - or just the portion of it you most want to hear.
And with Aiwa's exclusive  "3 Minute Warning" Remaining Tape Time Meter you'll never worry again anout running out of tape. All you do is check the left meter.
Wow and Flutter have been reduced to an outstanding 0,04% (WRMS). And there's Dolby  NR with MPX filter.  As a special limited introductory offer, every Aiwa AD-6700 comes with one free cassette of Scotch " Metafine Pure Metal Tape.  Now whatever metal-particle tape can do, the new Aiwa AD-6700 makes it do better.

With full-function wireless remote control.
Advanced feather-touch logic controls make the Aiwa AD-6700 a pleasure to operate. Plus it's the first cassette deck in the world with full-function wireless remote control that includes the extra freedom of Cue snd revies - even from across the room. So anything the Aiwa AD-6700 does, you can do in the palm of your hand.
