Technics RS-1500/1506 (1976) - Professional in Every Sense

 

reel to reel

Both performance and operational advantages of the "Isolated Loop" tape path introduced in the Technics RS-1500US and RS-1506US qualify these professional units not only state-of-the-art, but as the begining of a new technological generation. To realize the full potential possible with this design, there was no choice but to employ an all direct-drive tape transport system, with quartz-controlled, phase-locked servo control. Electronically as well, these units were built as an uncompromising challenge to tape decks now available. Separate microphone amplifier, recording amplifier, mixing amplifier and three-way bias and equalization controls all serve to help assure flawless recording and playback under any circumstances. Unique in tape recorder technology, the capstan of the RS-1500US is 34 mm in diameter, for increased tape contact and less possibility of slippage. 

By means of two pinch rollers in contact with the same capstan, an isolated, closed-loop system is formed. The direct-drive oncept was originally introduced by Technics in 1969, for use in high-grade turntables, and was adopted in the Technics RS-275US cassette deck in 1970. In 1976 with the introduction of the the RS-1500US, direct-drive is applied to a tape transport system (the capstan, flywheel and motor all rotate as a uniform entity) ​The direct-drive principle extends to the reel motors, also. Brushless DC motors of very high torque, with electronic commutation, are unitized with the diecast reel tables. The RS-1500US is designed for 2-track recording and playback as well as 4-track playback of tapes made on other decks. The RS-1506US is designed for 4-track recording and playback as well as 2-track playback of tapes made on other decks. Technical data: Tape speed: 38 cm/s, 19 cm/s, and 9.5 cm/s Frequency response: 30-30,000 Hz (38 cm/s) 20-25,000 Hz (19 cm/s) 20-15,000 Hz (9.5 cm/s) Dimensions 45.6 x 44.6 x 25,8 cm Weight 25 kg.

FIDELA by Nakamichi - The Origin of Nakamichi

 

reel to reel

Nakamichi was founded by Etsuro Nakamichi in 1948 as Daiichi Onkyo Co. Ltd. which in 1958 became Nakamichi Research Corporation Ltd. and it was later headed by the founder's younger brother Niro Nakamichi. The company specialised in manufacturing portable radios, tonearms, speakers, microphones (Primo Dynamic) and communications equipment but it was only after 1972 that they started using the Nakamichi brand name. 

In 1951 they have developed one of the first open reel tape recorders in Japan under the Magic Tone brand, these were initially sold as a kit. In 1957 they developed and manufactured proprietary magnetic tape heads and started manufacturing reel to reel recorders, for US distribution as OKI 555 (1962), and under the FIDELA brand name. In 1965 they have launched the Fidela 807 3-head Open Reel Stereo Tape Deck, also rebadged as harman/kardon TD-3 and KLH Model 41. They also made one of their first cassette recorders as Fidela NR-11 in 1967. Because of its experience in manufacturing magnetic tape heads and equipment, in 1967 the company started making tape decks for a number of foreign manufacturers including Harman Kardon, KLH, Advent, Fisher, ELAC, Sylvania, Concord, Ampex and Motorola. (Fidela model range: 11, 22, 33, 55, Studio 77, Studio 77D, 300D, 300DS, 720, 780, 807, 860, 920, 960)

PIONEER CarryCom system (1983) - A New Concept in Compact Stereo.

 

boombox

Pioneer's CarryCom System was a new concept in compact stereo components. It packs like a portable, but unpacks into individual components - speakers systems, versatile stereo FM/AM tuner/amp combo and fully-equipped stereo cassette deck. Together they add up to integrated component system, just like home hi-fi's. When sold as complete system the following combinations were available: CK-3, CK-W3, CK-5, CK-7T and CK-R11. Your options however are not limited to these "ready made" combinations as the CarryCom System is a modular system and the components are designed so you can choose exactly the right combination of units that best matches your needs - and your budget. These are the components that you could choose from: 

TUNER-AMP: FA-C3 tuner-amp with analog AM/FM Stereo | FA-C5 tuner-amp with analog AM/FM Stereo, 5-band Graphic Equalizer | FA-C7T tuner-amp with Quartz-PLL Synthesizer preset SW/MW/FM Stereo tuner, 5-band Graphic Equalizer. All models feature the same power output: continuous average power 12.5 W/ch, min. at 6 ohm from 60-20.000Hz with no more than 5% total harmonic distortion and the same size, 225x110x150 mm. There was an additional Power Amplifier as well with continuous power output of 30 watts per channel, min. at 6 ohms from 40 to 20.000Hz with no more than 5% total harmonic distortion. Size: 225x110x192 mm, weight: 5kg.
CASSETTE DECK: CT-C3 stereo cassette deck with Dolby noise reduction and Automatic Level Control | CT-C8 stereo auto-reverse cassette deck with full-logic control, auto tape selector (Metal/Chrome/Normal), music search, Dolby noise reduction | CT-C9W stereo double cassette deck with 2+2 motor transport, double speed tape copy, relay play, full-logic control. The CT-C3 and CT-C8 have the same size 225x110x150 mm, and can be powered by any of the tuner-amplifiers or with 10 D-type batteries. The CT-C9W dimensions are 225x110x200 mm and can be operated from the mains or external DC: 12-15V.
SPEAKER SYSTEMS: CS-C3 2-way bass reflex with 12cm cone woofer and 2.5cm Ceramic Tweeter, 6ohm, 50-20.000Hz, 45W, 168x226x150 mm | CS-C7 2-way rear open type with acoustic dampers, 15x21cm Pioneer exclusive Flat Woofer and 9cm cone tweeter, 6ohm, 40-20.000Hz, 100W, 168x226x150mm | CS-C11 3-way rear open type with acoustic dampers, 15x21cm Pioneer exclusive Flat Woofer, 9cm cone tweeter and Ribbon Supertweeter, 6ohm, 30-50.000Hz, 100W, 168x336x150 mm.
Additional components are the PL-C7 belt-drive turntable, AC-C7 accessory case, AD-C23 carrying handle and mounting set.
The Pioneer exclusive FLAT WOOFER covers the front panel of the speaker enclosure edge to edge. You get much more bass in far less space. All the center is a cone tweeter to handle the mid and high frequencies with maximum clarity. A port on the rear, and special acoustic dampers on one side of each enclosure add dimension and authority to the sound. In the 3-way CS-C11 systems, superhighs are handled by the Ribbon Supertweeter.
