TANDBERG TCD 900 Series (1985) - Professional Cassette Decks

Professional Cassette Decks


With the introduction of the TCD 900 series, Tandberg broke the barrier of professional cassette use. In one machine are combined superior sound capability, superior mechanical and electronic quality, control flexibility based on an 8 bit micro processor with 32 K of EPROM memory. Introduced in 1985 the TCD 910 was a Master Cassette Recorder while the TCD 911 was a Playback Cassette Deck. Both deck feature Direct load cassette compartiment with electro mechanical locking of the cassette and four servo control motors - one each iron coreless spooling, one DC servo frequency generator capstan drive and one DC servo pinch roller/head bridge actuation. Both are dual capstan closed loop drive with direct opto-electronic sensing of hub spindle rotation for precise real time counter accuracy. The TCD 910 features recording head azimuth adjustment while the TCD 911 features playback head adjustment (both external and manual adjustments) The incorporated DYNEQ, Tandberg's patended headroom extension system and ACTILINEAR II (a transconductance amplifier which takes the record and bias signals as pure voltage and converts them to pure current) contribute to superior sound performance. The built-in tape calibration system (TCD 910) allows optimum performance with all type I, II or IV tapes on the market. For studio use these decks feature electronically balanced XLR input/output connectors, RS 232 data interface for program automation and 19 inch rack mount ears. Only 400 of these units were built.

TANDBERG TD 20A (1977) - 4 Motor Reel to Reel Recorder

Reel to Reel Recorder

The TD 20 A was Tandberg's first open-reel recorder to incorporate the ACTILINEAR process. ACTILINEAR recording include a dramatic increase (20 dB) in the signal handling capacity of the record electronics making them essentially immune to slew-rate limiting and transient intermodulation distortion (TIM). This means better transient response and lower distortion level. Front-panel bias adjustment controls have been included to facilitate optimum performance with any known or prospective tape. Four separate record-level controls, plus a master record control, permit full mic/line and line/line mixing, and a switchable 25 dB mirophone attenuator is provided to prevent possible overload when using high output speciality microphones. 

The TD 20 A transport contains four motors rather than three. The capstan is driven by a brushless synchronous motor, and uses a belt drive and heavy flywheel to eliminate vibrations from being transferred from the motor to the capstan. The two reel motors are directly coupled to the reel turntables, and are controlled by a "PROM" (program read only memory) with a trial output to provide constant tape tension. The fourth motor is used to operate the pinch roller and tape gate, achieving smooth, noisless control impossible with the conventional solenoid activated system. A 5 mm thick aluminium baseplate rolled under 40 tons of pressure in a unique "honeycomb" design eliminates stress and greatly increases strenght. Tandberg's full-logic button control permits you to go from rewind into playback with complete safety, and allows the inclusion of "step-stop" editing with full monitoring capability. An optional infra-red remote control is also available. It was sold in two versions: 4 tracks and 2 tracks.

Tandberg TCD 3004 (1980) - Masterpiece of European Tehnology

cassette deck

The Tandberg TCD 3004 was part of the Series 3000 components from 1980, quite simply a new standard in sound reproduction. The result was a system with no compromise, a Masterpiece of European Technology. The Tandberg TCD 3004 is a Professional quality cassette deck featuring microprocessor-controlled 4-motor, Dual Capstan tape drive mechanism with a 3 head configuration system. The deck can be optimised for all tapes on the market without the use of external meters, and without internal adjustments. For this purpose advanced electronics are used such as Dyneq head room expansion and Actilinear recording- and phase correction circuits. Comfort features include variable winding speed, cue/review with automatic tape speed reduction and separate left and right channel output level. Optional remote control was also available. Specification: Frequency range R/P (+/- 2 dB) 19-21000 Hz, Signal to noise (IEC A-curve) 70 dB, Speed variations WRMS 0.09%, Dimensions (cm): 43.5(W) x 22.9(H) x 14.9(D) Weight: 10.3 kg

7 Cassette Decks....Then They Were Vertical

AKAI on the wall - 1974

When we say Cassette deck we normally think of a square box of a component that can be stacked one on each other. This was not however always the case. In the 70's some manufacturers tried a different approach by promoting vertical standing models that can be wall mounted or simply standing next to a tape recorder - like the big boys. Here is a selection of vertical standing cassette decks by various manufacturers.

BIGGER = Better ?


These are some of the BIGGEST cassette decks ever made. Were they better than a regular sized deck ? In some cases yes, they were hiding a complex mechanical construction and sophisticated electronics to achieve the best possible sound. Let's take a look at the models and the years they were made.

The AKAI GXC-570D  was first manufactured in 1975 and it features 3 heads and 3 motors.


The eumig FL-1000 was made in Austria in 1979. This is a highly regarded cassette deck.


The OPTONICA by SHARP RT-6906 from 1981 was a 3 head machine with an extra head for a sophisticated track search system. 

The PIONEER CT-A1 from 1979 is a 3 head unit with a complex tape calibration system. Briefly sold as Linear Phase 7000 a company that was recently acuired by PIONEER.


A big and beautiful cassette deck from Norway. This is the TANDBERG TCD 3004 from 1980. 


A not so well remebered model is the TEAC A-860 from 1976.


A two box solution from Technics. This is the RS-9900US from 1977.


Here is something interesting, something you would not expect. These are two models from 1977 made by UNITRA from Poland. They are the UNITRA M-601SD and the 3 head UNITRA MDS-624. 


Finally the BIGGEST of them all but never manufactured. The LUXAN X-3K, only shown as a prototype. With this system the aim was to completely extract the tape from the cassette and run it on a free and precise tape path.
