D-M33 RCD-M33 CD Receiver + SC-M53 Loudspeaker

Remarkable Sound from a Compact System

Building on the basic design of Denon's critically acclaimed D-M31 and D-M30, Denon engineers have continued to refine design details and parts
through repeated tests in order to achieve an even higher level of sonic perfection. These engineers have also collaborated with European sound design ers
and technicians to develop a new speaker system that would faithfully deliver the improved sound quality from the D-M33, Denon's latest micro Hi-Fi
system. The D-M33 not only plays CDs but a variety of other sources such as MP3 and WMA sound files as well, in the rich quality of sound that has
made the Denon name so famous.

■ The D-M33 inherits Denon technology from high-end models to faithfully
reproduce the original sound.

Capacitors developed for high-quality audio have been used in the circuitry of the
power amp that determines sound quality and in the D/A converter section that
converts the digital signal from the CD into an analog signal. In addition, the D-M33's
high-class separate components feature Burr-Brown D/A converters from Texas
Instruments Inc. that are well known for their superior sonic performance. The
converters faithfully preserve both the powerful dynamics and the delicate nuances of
sound as they convert the CD's digital signals into analog form for the speakers.

■ MP3 and WMA playback

In addition to CD and radio sound sources, the D-M33 also plays MP3 and WMA
files recorded on CD-R or CD-RW media. To play these discs, simply load it and
push the Play button. You can also select a folder on the disc and just play the files in
that folder. When a file is played, the artist name, song title, track number, album
name and other information is displayed. Repeat or Random playback is also possible.

■ Hi-Fi Speaker system with the New European Tuning

The SC-M53 is a speaker system with high sound quality that has been newly tuned
for the RCD-M33. The bass driver has an inverted-profile double layer cone. This
one-piece design does not use a centre-cap and therefore provides greater rigidity

across the surface of the bass cone.

Newly-developed drive unit

As shown in figure 1, the driver uses an inverted-profile double layer cone. Detailed
“finite element analysis” was used to find the optimum thickness on each part of the
subcone and the best connection point between main cone and voice coil. This
design controls the break-up modes of the cone for a more stable sound. Figure 2
shows an analysis of the woofer diaphragm at 1.4 kHz. Piston motion is uniform over
the entire diaphragm even at this frequency which is high for a woofer. In addition,
the secondary cone has not been bonded to the edge of the driver in order to optimize
control over vibration to the outer perimeter. This design thoroughly minimizes
influences on the secondary cone that actually emits the sound.

Speaker cabinet

•

The speaker cabinet is constructed with MDF material. The acoustic design of the
cabinet was optimized through laser scan measurements of vibration in the cabinet.
The cabinet also features a white wood grain finish that is often used in northern
European furniture. Careful attention has been given to the rear of the speakers as
well, where higher quality 5-way binding terminals are featured.

Network

•

An acoustic fourth order LCR filter has been used for the network to obtain opti­mum phase matching between the woofer and tweeter.
