PMA Integrated Amplifier

A new series of DENON amplifiers, incorporating a wide dynamic range,
low noise MC amplifier. it reaches the highest class in the most lun-

separation. By coupling all stages with a pure complementary circuit from
MC amplifier to power amplifier using both PNP. NPN transistors, an ultra

DP-IZN Direct Drive Player

The DP-1200 is provided with automatic arm lift for the ease of
operation without deteriorating its performance. The DP-l200 is a high
perlormance record player with the unique DENON technology
realized on such pans as the non contact type recordend sensor, the
adjustable tonearm height, the stand-by switch for starting after a
cueing, and howling prevention.

DP-m Direct Drive Player

A magnetic signal detecting system and high precision servo phon
motor is employed and uses a tonearm whose effective length is 24
m/m which is regarded as the longest in this class. 0 The greate:

DIE-750 Stereo Cassette Tape Deck

DENON has researched on better tonal quality through a tape trans-
port mechanism, the head, and the amplifier to design the DR-750
cassette tape deck. The tonal quality depends on the characteristics
and the construction of the tape transport mechanism and the head.
Recording and playback head consist of unique Sendust tip
developed by DEMON, so that it records with a wider dynamic range
together with a superior recording linearity and the lowest distortion
at a high level. Combined with the DENON high quality head, model
DRv750 achieved an excellent tonal quality and the performance of
tape transport which is superior to a 3-head system.

on-aso Stereo Cassette Tape Deck

In the DENON stereo cassette deck, an emphasis is placed on a tape
transport system and on an optimum recording performance which
are the basic performance of the tape deck. And adequate coun~
termeasure against operational fault and the protection of tape is
provided by permitting ease of operation. The accuracy at the cas-
sette holding position is increased, and self-centering hub drive
assures a tape transport with a high precision.
