QUANYINSU S3L Car Power Amplifier 150Wx4 DSP Audio Processor Lossless Car Audio Modified Subwoofer
Description:
High fidelity sound quality
In terms of sound quality, the design concept of S3L is based on the reduction of sound quality. Excellent circuit design and reasonable materials are the basis for good sound quality. From recording to replaying the signal, there are many electronic components. In this process, the sound quality is only reduced but not increased, so reasonable circuit design and materials are made to ensure that the sound quality is reproduced without loss. At the same time, this product draws on BBE's audio processing and restoration algorithm, and adjusts and restores the delayed and distorted signal output from the original car host to make the sound quality clearer. Based on the sound quality restoration, the sound quality processing is used as the auxiliary to achieve high fidelity sound quality.
31-segment audio processing
One of the functions of DSP power amplifier is sound processing. Car audio, irregular spatial layout, and the coordination of different equipment all require DSP adjustments. S3L DSP sound effect processing function, supports 31-segment mobile phone computer tuning, which can solve the sound effect problem well.
Amplifier function
This product uses Japanese transistors, a boost high-power design.
Pleasant sound, using AB class amplifier design
This product adopts class AB power amplifier design. Class AB sound is soft and delicate, with better detail reduction and sound fidelity. Imported materials such as OPA4131 operational amplifier and high-power and high-standard patch materials are the basis of beautiful sound.
S3L high quality
S3L DSP, with better materials, is a real high-power audiophile DSP amplifier. It is at the mainstream level in terms of sound quality and sound effect, and is superior in power and tone. S3L circuit board drawings, truly independent design.
Multifunctional S3L
Equivalent to 1 high-end host (AUX input/Bluetooth input) + 1 DSP processor (31-segment mobile phone computer tuning, excellent sound quality processing) + 1 large power amplifier (Transistor, high-power class AB)
Non-destructive installation, real high power
When the traditional audio is refitted, the main unit is usually changed, the power amplifier is added, and the dsp is added. This is expensive, the line modification is complicated, the tuning matching is complicated, and there are many problems. Now it can be realized with a single product. S3L integrated mainframe, dsp, power amplifier , The non-destructive installation is simple and convenient.
Delay adjustment to improve the sense of hierarchy
The combination of Transistor's high-power AB class high fidelity and DSP technology, coupled with the on-site stage feel brought by the delay, will bring a leap in layering and on-site texture. Listen carefully, you will hear that every note is staggered You can clearly distinguish the positions of singers and musicians. The center console is a small stage, just like on the spot.
Amazing Control
Boost design, real high power, high power DSP, promote various modified speakers, good bass diving, high treble, high fidelity, better control of the entire audio system.
