JVC RC-M70 (1980)
|
|
Don't compare it with other portables, compare it to home stereo systems. JVC's RC-M70 radio/cassette recorder not only goes everywhere, but does everything with a super power output (7 watts per channel, min. RMS. at 8 ohms from 100Hz to 15kHz) pumped through a 2-way, 4-speakers system (16-cm woofers, 5-cm tweeters). That's enough punch to be the life of any party - in whatever room or wherever you roam. The RC-M70 is like a home stereo system that can leave home. It's "portable Hi-Fi". The RC-M70 features metal tape compatibility, Sen-Alloy head, manual/automatic recording level control, 6-band radio, and a 16-program Multi Music Scanner for the cassette. Its wow/flutter rating is among the lowest in a radio/cassette - 0.065%. There's more: separate bass/treble and recording/sound level controls, speaker balance control, cue/review/pause function and 3-way power adaptability. Plus, phono-input capability. Just add a turntable and your system is complete. All these features give you the control over sound that you expect from larger, more expensive systems. Dimensions: 554x303x151 mm | Weight: 9,0 kg (with batteries).
JVC RC-M90 (1981)
|
|
The RC-M90 was the largest boombox from the 1981 JVC line-up. The radio section of this unit has an 8 Waveband tuner with shortwave split 6 ways for easier, more accurate tuning. For better FM channel separation, the multiplex circuit uses a PLL (Phase Locked Loop) IC, easy-to-read 15 cm tuning dial, large high-inertia flywheel with independent drive belt for smoother tuning, FM Stereo LED, signal strength meter for easier tuning, twin telescopic antennas and terminals for the connection of an external antenna. The amplifier section features a BTL (balanced transformerless) power amplification circuit delivering 40 watts maximum output power (20W + 20W) to a 2-way loudspeaker system. The 2-way 4-speaker system features two 20cm woofers and two 6.5cm tweeter. New polyurethane laminated cone paper makes woofer stiffer for in phase vibration and resistant to water splashes. The amplifier section has independent bass and treble tone controls, loudness switch and balance control.
The cassette recorder section is a solenoid operated advanced two-motor full-logic tape transport system that gives wow and flutter of only 0.05% WRMS. Specially designed heads make the most of Metal tape with Metaperm record/playback head and 2-gap SA (Sen-Alloy) erase head. A 3-position tape selector allows optimum bias and eq. for any tape while a 5-Program Multi Music Scanner lets you skip backwards or forwards so that playback starts where you want it to. The ALC (Automatic Level Control) automatically sets optimum recording level while the manual override lets you set recording level manually referring to right and left meters. (Meters also function as battery checker and tuning meter). The cassette recorder features both Super ANRS and ANRS (Dolby B compatible) noise reduction system. There is provision for headphone and microphone on the front panel while on the rear panel there are secondary microphone jacks, line out sockets, selectable phono/line-in sockets (RIAA equalizer built in so that a turntable can be connected directly) and external speaker connectors. The optional remote control (R-15E) has a front panel located connector. This was a very popular boombox that can be found on album covers such as LL Cool J - Radio (this one has a 1:1 scale image printed on the cover) and The Beastie Boys - Solid Gold Hits. The JVC boombox range was extensively advertised in print magazines by the likes of the Harlem Globetrotters or famous sport personalities. A more recent "digital portable player" is shaped as a miniature replica of the RC-M90. Dimensions: 668x350x177 mm with handle | Weight: 10 kg (without batteries) | Operation: Mains, 10 "D" batteries, car battery with optional adapter.

Technics SA-C07 (1980)
|
|
The SA-C07 is one of the most powerful 3-piece boombox from the 80s. Different from all the rest, the SA-C07 includes a tuner, preamp, power amp and cassette deck in one rugged chassis. Performance specifications for this FM/AM stereo cassette receiver are excellent. Yet there are no time-consuming connection procedures to bother with. The SA-C07 is compact and portable. The large carrying handle makes it easy to move the unit from room to room, or in and out of your car. Like any true hi-fi system, the SA-C07 can be used with your choice of speaker system, large or small. For portable use, the optional SB-F07 speakers can be hooked right into the sides of the unit. Of course, the preamp section includes phono equalizer circuitry so you can connect a turntable and enjoy your favorite records. Because it's designed to run on AC or DC power, the SA-C07 can be used as a car stereo, or outdoors (with optional car battery adapter). The tuner section features Quartz Synthesizer Tuning with 12 stations (6FM/6AM) presettable and a large fluorescent display. The cassette recorder section features a 2-motor IC logic- controlled deck mechanism with Metal tape compatibility, LED peak power meter and Dolby noise reduction. The amplifier section is able to produce plenty of clean power: 30 watts per channel minimum continuous RMS into 8 ohms, both channels driven, from 20-20,000Hz, with no more than 0.04% THD. These specifications are quite good for a home amplifier, but truly astonishing for a portable unit like the SA-C07. To complete this lightweight portable system a pair of SB-F07 speakers are included. Their enclosures are made of tough, durable TNRC (Technics Non-Resonant Compound), which is very light in weight yet anti-resonant.
