TELEFUNKEN M1 (1980) - Small, Funky and Big Sound

TELEFUNKEN M1 mini hifi

The Telefunken Mini-HiFi M1 system was introduced in 1980 and the same year it received the "Deutschen HiFi-Preis 1980" for design excellence. The heart of this system is the MA1 stereo integrated amplifier that can deliver 50 W/ch (4 ohm) with a THD of less than 0,1% at 1 kHz (45W/4 ohm). The all DIN plug systems allows connections of a  tuner, two tape, auxiliary and phono source. The amplifier can be used with two pairs of loudspeakers, one set is for DIN speaker plugs while the other is of a push terminal type. All switches have red LED feedback while for power output there are two 12 segment LED power meters with meter range switch. The MT1 tuner is a Quartz Synthesizer model with digital display and 10 memory presets. This is a FM stereo - AM - LW tuner with manual tuning or direct frequency input model. Again, each button has red LED feed back. Next there is the MC1 cassette deck recorder. This is a two motor - two Sendust head, logic controlled model. It can handle all cassette types: normal, chrome, Fe-Cr and Metal (30-18000 Hz) The primary noise reduction system of this model is the High-Com system (74 dB chrome tape) invented by Telefunken. For further compatibility the deck features also a playback only Dolby system (hence the half Dolby logo) For manual tape recording there is a 12 segment/ch LED peak level indicator, and again all controls have red LED feedback. A detailed description of the similar HC 750 M model (introduced in 1982 as replacement for the MC1) can be seen in the 1001 Hi-Fi Collection. The recommended loudspeaker for this system was the Telefunken TLX 11 Professional.

MITSUBISHI micro 01 (1979) - High Performance, Small Package

MITSUBISHI micro hifi

Mitsubishi (Diatone in Japan) has put big audio performance into a series of precise little audio components - microcomponents. Stereo components that are compact, but can hardly be called compacts. They have the same high-performance characteristics as full size components. The Micro FM tuner is using a quartz-PLL synthesizer tuning system that has absolutely no drift. The Micro Cassette Deck has a Dual Capstan Drive mechanism mounted in a precise die-cast chassis, 2 head configuration, separate Bias and EQ settings, Feather Touch Logic Control and Dolby noise reduction system. For power, the Micro power-amplifier was unbeatable at this size. The little "direct coupled" powerhouse puts out 70 watts per channel. Total harmonic distortion is only 0.01% for 30 watts per channel. The Micro Preamp is made to complement the power amplifier and faithfully conduct any signal source that goes through it. It has a built-in moving-coil head amplifier and a signal-to-noise ratio of 77dB and 0.005% THD. The final touch was to finish them with Champagne Gold faceplates. The MITSUBISHI micro 01 (DIATONE µ in Japan) cosnsists of  M-F01 tuner, M-P01 pre-amp, M-A01 power-amp and M-T01 cassette deck.

ITT HiFi8025 (1979) - Who Made Who ?

cassette deck

A very interesting cassette deck was introduced by ITT in 1979 for the European market. ITT (an American company) owned through it's subsidiary Standard Elektrizitätsgesellschaft several European brands such as Schaub-Lorenz, Ingelen or Graetz. The ITT HiFi8025 was part of their Performance-Line HiFi80 System. This is a high performance 3-Head cassette deck with a 2-Motor Closed Loop Dual Capstan mechanism mounted in a die-cast chassis. There are several other high-tech features present on this deck such as: manual BIAS with test tone, azimuth adjustment, fluorescent peak level display, source input mixer, adjustable output (at the back) and soft touch logic tape transport control. No Metal tape capability yet on this model so its top performance can be achieved using Fe-Cr tapes. (25-21,000 Hz) Previously hi-fi products in Europe were sold as ITT Schaub-Lorenz but this model was simply labelled as ITT, however there was another version of this deck sold as INGELEN HC 500 while the service manual had a ITT-Graetz logo on it ... There is further mistery around this deck as the 3-Head arrangement looks very similar to what Tandberg had used while the mechanism-head arrangement looks very much like the one used by the Mitsubishi DT-30 (DT-40). So why do I even mention the Tandberg name in this discussion when there's no proof that can link this ITT to Tandberg ? Well it's because in the early 80s when TANDBERG introduced the TCD 3034 there was a version sold also as ITT 3020 (and a service manual with ITT-Graetz logo) All this looks like that there was a "love triangle" between ITT-Tandberg-Mitsubishi, but ... Who Made Who ?

AKAI DA-P9500 / DA-A9500 (1989) - The 60th Anniversary Model.

digital amplifier

To celebrate it's 60th anniversary AKAI created in 1989 a dream amplifier (sold as A&D in Japan). It was a 60 units limited edition Digital pre-power amplifier. Out of the 60 units made, 30 were sold in Europe. The AKAI DA-P 9500 pre-amplifier acts like a Digital Controller where the analog signal is converted to digital and the signal is transmitted in digital format to the power amplifier. There are 12 analog inputs, 4 digital coaxial and 4 digital optical. There is rec-out for tape, 2 vcr and 2 digital. The pre-amplifier has a digital parametric equalizer that can be controlled via the 2 way system remote. EQ settings can be easily visualized on the two way remote controllers display. Dimensions: 466x154x445 mm Weight: 19 kg
The AKAI DA-A 9500 is a 200 w/ch (FTC 20-20000Hz 8 ohm) power amplifier that has a built in D/A converter and can be used as an independent unit for digital sources and it can be controlled with it's own remote control. Dimensions: 466x214x498 mm Weight: 35 kg
