When you hear that one car audio shop sold over 100 power amplifiers, one valued at 6000 Yuan, in one month, you might easily think it's nothing but false advertising.  

The shop making such an achievement is Hangzhou Fenghuolun and the star products sold are Rainbow DSP: SL PRO-P1250A and SL-P0855A. How did that happen?

SL PRO-P1250A

 SL-P0855A

Hangzhou Fenghuolun, a known car audio shop with a leading edge in products,technologies and service. It has created a sales record of 2 million Yuan in one month and was widely recognized by customers.

When the shop received SL PRO-P1250A and SL-P0855A, the shop owner launched a "trade-in" promotion campaign, which attracted numerous customers.

The shop's promotional strategy was definitely worthy of praise, and the high quality of SL PRO-P1250A and SL-P0855A made the sales performance even better.

Both of these two products have built-in amplifiers and with equipped cables, they are suitable for damage-free installation. Also, the technical design and the modern appearance could easily capture the hearts of car owners.

SL PRO-P1250A and SL-P0855A are fascinating from inside out. That's why they win over a significant number of the audiophiles.

When a car owner pays for a DSP, he or she hopes the DSP helps to unlock the potential of the speaker system to the utmost. The gain setting process involves matching the points where the head unit and amp begin to distort.When the amp gains are too low, there would be background noise, or “hiss” takes over. Too high, and music becomes distorted even at a normal volume level.

To solve this problem, SL PRO-P1250A and SL-P0855A are equipped with the function of clipping and distortion auto detection, which ensures that no damage be caused to your gear while tuning your speaker system so that your system can play its best.

The clipping and distortion auto detection fundamentally solves the problem met in the sound tuning process. The tuner has no worries about damaging the gear and could do his best and the car owner would get the most out of his or her sound system.

Apart from clipping and distortion auto detection, SL PRO-P1250A's and SL-P0855A's expert components define what is true audiophile-grade DSP.

SL PRO-P1250A adopts TEXAS INSTRUMENTS top 7000 series 300MHz 64-bit floating point DSP processor with a high-performance cross switch providing fast and powerful I/O signal transmission.

Also, it adopts TI PCM 3168A, the 192kHz audio codec, supporting single-ended and differential-selectable analog inputs and differential outputs, offering better anti-interference properties. As for digital signal input, it uses CirrusLogic CS8422 audio processor for digital signal input and Hi-Fi class performance.

SL PRO-P1250A has a built-in 12 channel class AB amplifier featuring STMicroelectronics TDA7851L power amplifier and WIMA capacitor 0.1uF/63V for low output noise, low distortion and HIFI performance.

Let's take a look at SL-P0855A.

Its DSP processor uses ANALOG DEVICES’ AUAD1452, up to 294.912 MHz, 32-bit SigmaDSP core at 1.2V.

Together with TEXAS INSTRUMENTS’PCM 1861, the 24-bit, 192kHz audio ADC with high sampling frequency, SL-P0855A is able to reproduce more naturalness and details.

It has a built-in 8 channel class AB amplifier featuring STMicroelectronics TDA7851L power amplifier and WIMA film capacitor, which helps to realize good resolution in high frequency while the mid and bass are just right.

The technical design and the industry-leading components speak for Rainbow's value - the ultimate thing that can happen to your ears. That is why these two new DSPs are so popular with customers.

It's nothing about false advertising, it's about Rainbow quality. You can always count on Rainbow quality.
