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.

Pioneer CT-6R cassette deck

A full-featured cassette deck

You'll find in the CT-6R all the essential technology of the finest Pioneer decks. Features like the Ribbon Sendust Head, 3-motor direct drive design, C.A.C. (Computer-Aided Convenience), ans so forth. It's priced, however, within the reach of any audiophile.

Just as in our finest decks, you'll find a Pioneer-exclusive head design - the Ribbon Sendust Head - for recording and playback in this model. This laminated head uses a dozen ultra-fine sendust "ribbons" to reduce eddy currents and therefore reduce core loss. This results in extended high-frequency response, all the way to the limits of audiobility. Transient response and treble clarity are improved for better still reproduction quality. During playback this same head is used for either direction of tape travel, assuring matched response regardless of direction. During recording the "Small-Window" Erase Head is also at work wiping old recordings completely clean.

Another design feature found in our more expensive models is the three-direct-drive-motor system. One motor drives the capstan and the other two drive the reels. These brushless Hall motors are largely responsible for the low wow and flutter of this deck - a mere 0,04% (WRMS). This transport design also improves head-to-tape contact for fewer dropouts and variations in recording or playback levels

Hiss and MOL-limited saturation distortion have become problems of the past. New Dolby-C noise reduction has reduced noise by 20 dB at 5 kHz, while improving high-frequency response by expanding the MOL (Maximum Output Level). Now, the usable dynamic range - up to 90 dB - is sufficiently wide to match even digital or direct-cut recordings.

The C.A.C. (Computer-Aided Convenience) features that the CT-6R offers include index Scan, Music Search and Blank Skip and Reverse. And the three-direct-drive-motor tape transport offers quick and direct change of modes and flying-start recording.

Program peaks are shown by a responsive 8-LED bar-graph display (one per channel) Other advanced deck features include the Auto Tape Selector, one-Touch Recording, Recording Mute, a wired remote control and more.
