Kenwood DPX-9200WMP

The DPX-9200WMP is a 2DIN MD / CD receiver that supports MP3 and WMA playback. The MD section supports MDLP, and the CD section can also play CD-R / RW, MP3, and WMA. The maximum output of the amplifier is 50W x 4ch, and MOS-FET is used for the amplification element.

In addition to supporting ID3 tags Ver.1.0 and 1.1, the CD section also supports displaying the “title name” and “artist name” of WMA tags in Japanese. Supported bit rates are 48 to 192 kbps for WMA and 8 to 320 kbps for MP3. CD-R / RW discs with a mixture of MP3 and WMA can also be played.

A 16-gradation organic EL display is used for the display. The resolution is 256 x 64 dots, and the display content can be selected from 2 types of video, 5 types of still images, and 5 types of spectrum analyzers. It is also possible to download default videos and still images from the Internet and import them via CD-R / RW.

In addition to 11 patterns of SFC (hole simulation), the DSP section is equipped with time-delayed control, position control, compression, etc. In addition, the cutoff frequency and slope of the high-pass and low-pass filters can be set.

Sony's “CXD2726Q-1” is used as the DSP IC. Although not specifically mentioned in the product information, this model also seems to be “digital direct”. (Digital direct is a high-quality sound design that transmits signals as digital without passing through a D / A converter from the CD to the DSP section.) By the way, Caro has almost the same name as “digital direct transmission”. There was a crystal under the Kenwood IC.

Above the center is an IC called “Multitask LSI type Q” originally developed by Kenwood. It is an IC that integrates adjustment functions such as volume and digital equalizer into one chip. This was also not mentioned in the product information, but it was actually installed. Below is the IC of the crossover system “System E's Pro”. On the left is the JRC operational amplifier. But alas, the NJM2068D used in this is cheap. MOS-FET 50W x 4 power amplifier. It is not just a MOS-FET, but a “separate Power IC” configuration. To put it simply, left and right independent amplifiers. It's a natural thing in high-end home audio. By the way, Kenwood was the only car audio system equipped with left and right independent amplifiers at that time. There must have been no model equipped with similar things on Caro. A huge electrolytic capacitor. 16V, 4700μF. By the way, Caro's FH-P009MD was also a capacitor with the same capacity, but it was a little thin. The choke coil is built into the main body. Up to the predecessor model DPX-9021MPi, it was the one that was properly in the power harness part … This is the drive part of the electric panel. Is the motor like this? I wasn't sure where the noise was coming from, so I poured grease for the time being. The base of MD mechanism. The ATRAC IC is “CXD2667R”. … A diagram of connecting only the panels in a disjointed state.
