Earlier, the 360 auto network evaluation team evaluated the newly launched asp463bt audio processor of addzest in Japan, and produced relevant product shopping guide videos. For the text version evaluation content of this product, I will bring it to you in this issue. From the earliest asp461bt and asp462bt to the latest asp463bt, the series also includes asp8100bt with powerful function and higher power output, which makes ASP family have up to six products. Addzest in Japan has a very clear product positioning, and it has a very accurate feature positioning for asp461, 462 and 463 of sound source processing and details, which is worthy of in-depth study.
Analysis of ASP family tree
In terms of naming habits, Japan's addzest positions asp461bt and 462bt as DSP processors, while asp8100bt is a power amplifier for positioning high-power output. More emphasis on audio and sound source part of the product segmentation, by asp668bt, asp464bt three products. It is not difficult to see that one of the features of asp463bt evaluated by the editorial department is its built-in player function, which focuses on high-definition lossless audio source, and meets most of the current high-definition music playing scenes of car audio. The system can maintain a high-definition and high-resolution audio source playing environment. From the current car audio afterloading products, asp463bt is more inclined to car digital player products.
Two sets of components for one purpose
For the orientation of HD car player, products naturally need to have a strong audio "armed" force. Japan addzest uses the small program tuning system with brand characteristics on asp463bt to facilitate the tuning operation of the system. On the other hand, to better realize the rich functions of the audio player, we specially develop two groups of small programs independently, the tuning control center is one group, and the audio function control is another group. It seems that the two programs are quite "complex", but the practical application is that they operate independently and do not interfere with each other, which can better optimize the tuning output of the sound source selection system.

Rich choice, controller has surprise
On the sound source selection, you can connect the smart phone to play the high format sound source files of the music platform through the built-in Bluetooth 5.0 function. In terms of high-quality sound source, it supports FLAC, WAV, ape, wma, MP3 and other formats. The system has high resolution and clarity, and can listen to a variety of lossless music. It is worth mentioning that another feature of asp463bt is that it originally provides nva40bt wireless remote control, and it can also provide external nva200c multi-function data broadcast by wire. The former's compact design is equivalent to the control function of the multi-function steering wheel, with five buttons for playing, track selection and other functions, and the entire controller side is also a knob function; the latter's external controller with high-definition LCD screen, in addition to the conventional track selection, pause, play and other functions, has excellent knob design through damping degree, which can be used with buttons Four kinds of sound source input mode selection, switching and other functions are realized.

As a digital player with DSP power amplifier function at the same time, asp463bt uses class AB power amplifier circuit design to realize 4CH × 50W stable power output. At the same time, it applies high-quality components such as AKM and SMD circuit, with 105dB high signal-to-noise ratio and thd total harmonic distortion + noise < 0.01%. Using the tuning function of asp463bt, each function operation is easy to understand, and no matter mobile phone small program tuning or computer software tuning, it can achieve the same precision, each channel provides 15 EQ equalization, 20Hz-20KHz frequency adjustable, Q value can be accurate to 0.02, delay fine-tuning is 0.021ms, high-low-pass filter can be selected from 6db-48db, can also be turned off independently, can preset 6 groups of different scenes pattern.
360 auto network comments: more and more on-board digital broadcasting products appear, focusing on solving the weakest link of car audio refitting, high-definition lossless digital audio stream, and solving the problem of analytical power of sound quality of audio source. Addzest in Japan is from component selection to detail design and accurate sound correction. One machine integrates sound source playback, DSP tuning and power output in one, and with precise and convenient digital playback control, this is the case in the era of high-definition digital audio with live vehicle sound.
