D-M33 RCD-M33 CD Receiver + SC-M53 LoudspeakerMini Component SystemRemarkable Sound from a Compact SystemBuilding on the basic design of Denon's critically acclaimed D-M31 and D-M30, Denon engineers have continued to refine design details and partsthrough repeated tests in order to achieve an even higher level of sonic perfection. These engineers have also collaborated with European sound designersand technicians to develop a new speaker system that would faithfully deliver the improved sound quality from the D-M33, Denon's latest micro Hi-Fisystem. 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 hasmade the Denon name so famous. The D-M33 inherits Denon technology from high-end models to faithfullyreproduce the original sound.Capacitors developed for high-quality audio have been used in the circuitry of thepower amp that determines sound quality and in the D/A converter section thatconverts the digital signal from the CD into an analog signal. In addition, the D-M33'shigh-class separate components feature Burr-Brown D/A converters from TexasInstruments Inc. that are well known for their superior sonic performance. Theconverters faithfully preserve both the powerful dynamics and the delicate nuances ofsound as they convert the CD's digital signals into analog form for the speakers. MP3 and WMA playbackIn addition to CD and radio sound sources, the D-M33 also plays MP3 and WMAfiles recorded on CD-R or CD-RW media. To play these discs, simply load it andpush the Play button. You can also select a folder on the disc and just play the files inthat folder. When a file is played, the artist name, song title, track number, albumname and other information is displayed. Repeat or Random playback is also possible. S.D.B.

The bass driver has an inverted-profile double layer cone. Thisone-piece design does not use a centre-cap and therefore provides greater rigidityacross the surface of the bass cone.• Newly-developed drive unitAs 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 thesubcone and the best connection point between main cone and voice coil. Thisdesign controls the break-up modes of the cone for a more stable sound. Figure 2shows an analysis of the woofer diaphragm at 1.4 kHz. Piston motion is uniform overthe 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 optimizecontrol over vibration to the outer perimeter. This design thoroughly minimizesinfluences on the secondary cone that actually emits the sound.• Speaker cabinetThe speaker cabinet is constructed with MDF material. The acoustic design of thecabinet 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 northernEuropean furniture. Careful attention has been given to the rear of the speakers aswell, where higher quality 5-way binding terminals are featured.• NetworkAn acoustic fourth order LCR filter has been used for the network to obtain opti-mum phase matching between the woofer and tweeter.Figure 1 Newly-developed woofer unit Figure 2 Woofer unit vibration
