Compact Cassette Changers






Before playlist existed there were compact cassette changers. Juke box heroes. They didn't seem to catch on like record changers or CD changers however from time to time a manufacturer made such a unit. Here are some of them and the various concepts they used to implement the ideea.

PHILIPS N2502 (1969)



DENON CASSEMATIC 12 (TRC-798ED)
This cassette changer is from 1970 and is one of the first models. 
It used a slide mechanism for 12 cassettes.



Panasonic RS-296US
This Panasonic is a 20 cassette carousel changer from 1972. 
Advertised as the cassette player that can play up to two and a half days of music.



PHILIPS N 2408
This PHILIPS is 6 cassette changer from 1976. The first version of this model dates back to 1969. It uses a funny accesory to flip the casssettes to play both sides of the loaded tapes.
This also makes it one of the first autoreverse cassette decks as well.



SONY MTL-10
The SONY MTL-10 is a 10 cassette cartridge format cassette changer from 1982. They were available in several colours - for supermarkets as advertised in the brochure. It has Laser-Amorphous head and on the slide out cassette compartiment there are preset switches for each cassette for tape type and dolby on/off preselect.




AIWA AD-WX99
5 cassette changer from 1985 in a dual well construction where cassette compartiment 1 is the cassette changer for playback only.



PIONEER CT-M601R
The PIONEER CT-M601R is a 6 cassette changer from 1992. It is one of the last models that was also available as a dual well construction just like the previous AIWA.

SONY ELCASET and other prototypes






Here are a few of the ELCASET prototypes presented in Japanese magazines and hifi shows between 1976 and 1979.

With minor changes this became the SONY EL-7 model in 1977.

ELCASET, rise and fall of a Hi-Fi tape system





ELCASET was an analog cassette tape based audio format developed by SONY in cooperation with Matsushita (Panasonic) and TEAC in 1976. It was intended to offer a reel-to-reel system sound quality in a convenient cartridge format. The name comes from the expression "large cassette" or "L-cassette". Although the ELCASET used a 6 mm (0.25 in) wide tape running at 9.5 cm/s (3.75 ips), twice the width and twice the speed of a PHILIPS Compact Cassette it became a complete failure in the marketplace and by 1978 it completely faded-out from the market. This happened mainly because Compact Cassette had a more compact format and the dramatical improvement with the introduction of new tape formulations such as chromium dioxide and lower noise with the introduction of the Dolby B noise reduction circuit.
