Marantz CD-73 Compact Disc Digital Audio Player (1983-84)

The Marantz CD-73 Compact Disc Digital Audio Player employs ultra precise manufacturing techniques and sophisticated digital and servo technology to assure you an audio output which is the full equivalent of that at the studio console where the original recording was made. Your listening room will never be the same again!

Marantz has succeeded in developing a mechanism of unprecedented small size through use of its own independently developed ultra compact laser beam pickup and linear motor mechanism. This enables slim styling which complements that of other equipment in your audio set-up.

The disc loading mechanism in this player represents a new concept in loading compact digital audio discs which is based on Marantz's many years of experience with cassette decks. When the motor drive drawer is pulled out, the disc clamper automatically rises and the front panel tilts. All that is necessary is to set the disc in place.

The independent functions of three separate microprocessors are employed to ensure that the fullest use is made of the potential of digital audio recordings. Two high-speed 8-bit microprocessors interact with each other to assure perfect tracking by the focus servo, radial servo, and platter servo.

Together with a random access program, this unit allows three different programs to be stored for playback control. Each program allows up to 15 selections to be played back in any desired order.

Use of Marantz's own fully balanced swing mechanism ensures superb resistance to vibrations and inclination, as well as making it possible to increase the speed of random access.

Marantz 2270 Stereo Receiver

Marantz 2270 Stereo Receiver

1971

With the Model 2270 Marantz has launched in 1971 a legend in the market. The performance was amazing 70 watts per channel stereo. This was the beginning of the worldwide success of the Marantz receiver. It was the largest model of the 22XX series.

A receiver battle began among the big manufacturers such as Sansui, Pioneer & Co. Who can build the strongest receiver? Sansui ultimately won the war with the G-33000 from 1978 with a fighting weight of almost 50kg, a static challenge for any music systems furniture :)

After the first 22xx-series Marantz has launched the model again and again. With rising power has unfortunately the quality of the components was lost. I am happy with even one of the first 22er models may be able to hear my music. The sound is simply fantastic. The durable 2270 was produced in large quantities. There are a few on the market, get one, it is a valuable investment with a lot of fun every day with music ...

Marantz 4240 Quadrophonic Receiver

1974
The Marantz 4230 is created for stereo and 4 channel (Quadraphonic) sources. Marantz called the concept sonorous "Stereo 2 + Quadradial 4". Some quadro decoder systems are on board. For an optional SQ decoder, there is a recess in the base plate, it can simply docked. 
The rated output of 2x40 watts or 4x17 watts was always outbid in tests thanks to the Marantz typical transformer dimension. For the good FM reception with the possibility of multipath signal evaluation is a high quality FM front end module responsible. 
The versatile enabled receiver 4240 from the legendary first 70 series is true fun and gives an entirely sophisticated impression. It sounds like it's visual impression - great!

Onkyo TX 4500 MKII Stereo Receiver

1977
The first stereo receiver with quartz-synchronization for the FM band. Even the previous TX-4500 was a successful ONKYO upper middle class. Here the design has been optimized. For the display scale real thick glass is used. An expression of timeless elegance, in my opinion. A heavy receiver with high power for 3 pairs of speakers. 65 watt per channel.
