What is the best board for stereo?

In order to reflect the host's high taste, the host chose the wheat scene map. Maijingtu is famous for adhering to tradition in the audio industry. It has no grandstanding appearance and pursues the best sound quality. No matter how the outside world changes, the style of Maijingtu has not changed, and Maijingtu represents classics; The speaker is made by Dana, and it is a brand that fans love to burn. Dane is committed to pushing audio technology to the peak and looking for the best materials in the world to make speakers, which represents the glory of art; In addition, the car also launched two fever brands, DLS in Sweden and Genesis in the UK.

system configuration

According to the color of Mondeo instrument lamp, the host chose Maijingtu MX 406, which has dual 20-bit decoding processing D/A conversion, enough to make enthusiasts shine at the moment. The sound field power amplifier is Genesis in Britain, and the subwoofer power amplifier is DLS-A6 in Sweden. In order to reduce the space occupied by the suitcase, DLS-OA 10 is adopted. According to the speaker position of the original car, the front sound field only changes the treble position, and Dynamo 240MK synthesis system is adopted, because if Dynamo 240MK synthesis system wants to obtain smooth frequency loudness, the treble and bass speakers should be connected as closely as possible. Next, the wire configuration, according to the power to calculate the appropriate size of the power line, signal line and speaker line all adopt the Swedish DLS blue demon Ji series.

Installation technology

"Three-point equipment, seven-point installation". Construction technicians should follow the installation process in EMMA competition rules, and every detail of construction, wire protection and wiring should not be sloppy.

The host is fixedly installed. After all, it is an American car with a solid body, but it is far from the working environment of the audio system we require. The subwoofer is installed in the position of the original subwoofer at the front door. First, reinforce the original car door, and inject German sand board glue into the weld, mainly to reinforce the middle bumper. After the sand board is dried, it is treated with high-energy sound insulation materials.

Then make the speaker base and measure the distance from the original steel plate to the door trim. According to the shape around the base, the carpenter selects the high-density fiberboard with appropriate height for blanking, opening and waterproof treatment to remove impurities such as iron chips and sawdust in the inner cavity. After installing the woofer, first, connect the front sound field amplifier to locate the front tweeter. This involves changing the rearview mirror controller to the left front door storage box, and it takes more than three hours of audition to determine the installation angle and position of the tweeter.

At this time, the audition has a preliminary impression on the finished music expression; Then the front sound field tweeter unit is inverted, and the subwoofer is installed according to the shape and size of the isolation plate between the trunk and the cab. The upper piece is trimmed according to the radian and angle of the rear windshield, aligned up and down, perforated as a sandwich combination baffle, and filled with PU glue between the interlayer and the car body to reduce the friction between the wood board and the steel plate, strengthen the sealing and strength, crust the surface, and brush the subwoofer protective cover to complete the installation.

It took only one day to install the power amplifier, and the power amplifier base was made behind the back seat, equipped with lighting system and wire terminals.

Audition summary

After five days of hard work, I can finally turn on the machine. After 24 hours, the audition begins with L/R channel test, positive and negative phase test, and then the balance test of spectrometer. After the basic test, listen to Zhao Peng's "Nanping Night Bell" first, because the positioning, frequency response and three-dimensional musical instruments of this song can meet the needs of tuning and listening. Through listening, the activity range of sand in chord guitar, bass, violin and sand pipe is clarified, and the distance between vocal music positioning and musical instruments is clarified.

The next step is to feel the dynamics and momentum of the system and put on a heart sutra in Zhu Zheqin's Paramita. The harmony of more than 800 people makes the engine hood look like a small mouth, and the low frequency emitted by the drum 4 meters in the middle makes people feel standing on the edge of the drum. The vibration of the drum head makes the seat in the car inclusive with you. The owner is also very satisfied after listening. I'm a little sad to hear that, if he has higher requirements. ...
