Victor KD-3 (1976) - Tape it Live Recording

Victor (JVC) have been a major proponent of "tape-it-live" recording concept from the very beginning. The Victor KD-3 (JVC CD-1635 worldwide) - a compact, lightweight and fully portable deck which runs 12 hours on only six long-life "D"-size batteries - takes this concept even further. This easy to use and fumble free deck offers a recordist accuracy which includes a very low wow and flutter capability of 0.20% (DIN 45500) / 0.08% (RMS). Innovations exclusive to JVC without which this revolutionary portable cassette deck could not achieve its remarkable hi-fi performance include the coreless motor and advanced, high linearity SEN-ALLOY HEAD. Another is ANRS, JVC's noise reduction system, cutting tape hiss. A built-in monitor speaker (10cm | 1.2W RMS 8 ohm) lets you hear what you've recorded at any volume or tone. In order to achieve best results in any conditions a wide variety of accessories were available. Here are some examples: MU-201 uni-directional electret condenser stereo microphone for well-balanced stereo sound | MU-510 super-directional/uni-directional electret condenser microphone with accurately cardioid pickup pattern | TL-E71 sound focusing reflector. Big parabolic reflector concentrates sound from any source and boosts their level 6 times (15db). Various types of microphones can be attached. | MI-E60 6-channel microphone mixer with reverberator. This is a high quality 6-channel mike mixer equipped with reverberation units and panoramic potentiometers. Besides mixing sounds from 6 microphones or other sources you can enhance the music with reverberation facilities and shift the sound image to any position between the left and right of the sound field with the pan Pots. | CB-3 carrying case. Specifications: Frequency response 25-18000 Hz with chrome tape | Dimensions: 100x360x242 mm | Weight: 4.5 kg (without batteries) 5.0 kg (with batteries)

Sansui BA-3000 (1975) - The Definition Series

Uncompromising. When a musical performance must be reproduced to the most critical standards, The Definition Series from Sansui can deliver flawlessly the entire audio spectrum. The Sansui BA-3000 has all the design features of the Definition Series, with a power output of 170 watts per channel, minimum RMS, both channels driven into 8 ohms over a 20 to 20,000Hz bandwidth, with no more than 0,05 % total harmonic distortion; 340 watts, minimum RMS in mono. Features include: Four jumbo heat sinks coupled directly to the power transistors eliminate the need for a cooling fan. LED Power/Protector indicator on front panel glows red when power is switched on, turns green to indicate safe operation; turns red to warn of potentially harmful conditions. BA-3000 has all the safety features, subsonic filters and distortion-free toroidal coil winding power transformer. The Sansui CA-3000 is a stereo control preamplifier featuring advanced space-age design in every link of the circuit chain, for unprecedented accuracy. It has RIAA ± 0.2dB Equalization which is capable of meeting all the strenuous demands of contemporary disc recordings which feature extremely wide dynamic range. The CA-3000 handles an extremely wide frequency response covering all musical signals with low distortion, no clipping or noise. Features include: High input impedance and low output impedance, through newly-developed unit amplifier circuits: a differential amplifier at input, and an emitter-follower or SEPP buffer amplifier at output. Phono equalizer features a packed differential dual FET amplifier (with a matched pair of low-noise FET's) at the initial stage, and Class-A complementary SEPP amp at output. Full controls and connections for any combination you're likely to need.
