Marantz CD-73


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.
