ITT HC-9071 (1979) - Remote Controlled Hi-Fi

music center

The ITT HIFI-Center HC9071 was introduced in 1979 and it was one of the most complex units of this kind on the market. It features a 48 W/ch (Sinus DIN 4 ohm) amplifier, LW, MW and FM Stereo radio section with 11 FM presets, a 3-Motor logic controlled cassette deck with manual level control and Dolby noise reduction and a DUAL 491 A-RC Direct Drive turntable. The highlight of the system is the full control infrared remote called HIFI PROCESSOR. The remote control is situated on the right hand side of the music center in a dedicated place. By gently pressing the top of the remote this will be lifted for easy removal.  Below the remote there are preset controls for volume, balance, bass and treble. When operating the unit, volume, balance, bass and treble are electronically controlled via the infrared remote control. The front panel is dominated by a series of large (visible from distance) fluorescent status displays for volume, balance, bass and treble. The tuner section has also fluorescent displays for frequency and preset. In addition to the full remote controlled cassette section the turntable also has remote controlled start, stop and arm lift functions. This music center can be found under two more ITT owned brands, the GRAETZ HMC 400 and the slightly more rare INGELEN HMC 400 (see the one from the 1001 Hi-Fi Collection here) Size of the unit is 744 x 190 x 380 mm / 20,3 kg.

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 ?

3 HEAD cassette deck rarities

vintage audio

In this article we take a closer look to some of the rarest 3 head cassette recorders. They were either market specific models or were only made in low numbers so they hardly ever show up for sale on the second hand market.

First in this line-up is the OPTONICA RT-9100H. Optonica was a brand name used by SHARP for their high-end audio gear. This model is not necessarily rare but is definitely one of the less known 3 head recorders....with 4 head. Yes it is a genuine 3 head recorder with monitor function however there was a 4th head that recorded signals to the tape for a sophisticated music search system. It was available as OPTONICA RT-9 in Japan, OPTONICA RT-9100 the rest of the world, while the black version was OPTONICA RT-6905 that came with an additional programable timer unit.

The next model is from Austria and it was made by eumig (Elektrizitats Und Metallwaren Industrie Gesellschaft mbH. in Wien). Before eumig became known with their version of a rebadged Alpine, the eumig FL-900 or the famous eumig FL-1000 they made this 3 head model called the eumig Metropolitan CCD. Released in 1977 this cassette deck uses heads from WOELKE (Germany) mounted on a full die-cast chasis. Instead of the usual rec/playback sandwich head this model uses an independent playback head while the recording head is sandwitched together with the erase head and there is azimuth control for the recording head.

Moving to the next model there's a 3 head cassette deck from a turntable specialist. This is the Lenco C 2003 Direct Drive dual capstan 3 independent head cassette deck from Switzerland. (699 USD 1977)

Talking about turntable specialist, here's the one and only Thorens PC-650 3 head cassette recorder from 1979.

Part of the slimline 777 system from SIEMENS this is the SIEMENS RC 777, a 3 head cassette deck with Sendust heads. This deck could be sourced from SANYO as the smaller SIEMENS 666 system uses rebadged SANYO units.

Another 3 head cassette deck is the ITT HiFi 8025 from 1979 (more detail here)

Last but not least here's a 3 head cassette deck from the former communist block. This is the UNITRA MDS 625 from Poland, a deck with dual capstan mechanism, 3 ferrite heads and dual speed (4,75 and 9,5 cm/s)

ITT HC 9071, one of the biggest music center ever





One of the biggest ever music center was made by ITT in 1979.
It was a completely "feather-touch" controlled music center where everything can be remote controlled using the big "HIFI PROCESSOR" (the remote).
The picture below shows the original ITT HC 9071 that was rebadged as Graetz HMC 400 and INGELEN HMC 400.
Our museum owns the INGELEN HMC 400 that you can see HERE.
