Any qualitative product is not only its components. Outstanding results are yielded by the correct implementation of each it's components. In the Resolut A-DSP processor the digital-to-analog converter AK449X, unique by the opportunities, which many experts call not differently as "most musical" is used in many respects. Having analyzed shortcomings of existing solutions on this chip, we implemented the maximum of its potential, including the switching like outlet filters allowing to select the nature of sounding which is best corresponding to your musical preferences and opportunities of the audio system.

The powerful processor from Analog Devices - ADAU1452 is responsible for the processing of the sound signal. All calculations are made in a resolution of 192 kHz / 64 bits that allows working without loss, even with the High-Resolution Audio formats. It is more than that, in Resolut A-DSP the original optimized algorithms are used, the opening possibilities of ADAU1452 and in addition increasing the accuracy of calculations more full. So an uncompromising approach allowed to achieve preserving of high resolution of the signal even at difficult processing’s in DSP. As well as the senior processors, the A-DSP model is constructed on modularity.

The processor can be completed with optional USB Audio modules based on Amanero or XMOS modules, the Bluetooth module and interface units of MOST 25 and MOST 150. Each of them is connected to the host ADAU1452 computing processor directly and is controlled by the 32-bit coprocessor. The sound flow is transferred to the DSP without any conversions reducing permission and signal quality, all switching happens directly in the processor.

In addition, to flexibility and customization of Resolut A-DSP under specific installation, such modular architecture allows to distribute computing resources of the processor optimum. They are not spent on support of not used functions, but any selected configuration works most effectively - whether it be work in multimedia mode, work with the optical bus of the car, sound quality optimization, the pastings mode of entrance analog signals during the work with regular systems, including compensation of the delays or phase shifts inherent in complex regular audio systems.

Data exchange between the host computing processor, the managing microcontroller and memory, happens on the high-speed bus. In combination with the use of high-speed memory such an approach allowed to exclude any possibility of data loss or their degradation including in the course of permanent reconfiguration. Any change of parameters and switching between preset takes place in real-time with the smallest delay. The resource of memory has the huge stock - even at record of 100 times per second the term of its fault-free service hypothetically is 31000 years. Speed and high reliability are especially relevant for participants of the autosound competitions wishing to receive not just powerful, but a reliable instrument of setup of the sound.

We paid special attention to one of the basic components of any audio device - power supply. In Resolut A-DSP specially developed multichannel supply system with the advanced pulse stabilizers working at frequency of 1 MHz and the linear stabilizers constructed on the discrete solution is used. Similar decisions are applied, as a rule, only in the most top uncompromising systems, in the majority of automobile processors, simpler decisions are used. Such a radical approach allowed us to receive the maximum quality of both digital processing of the signal, and digital-to-analog conversion, and as a result - to reach an unsurpassed quality of sounding.
