成果简介	NOVELTY - The car radio (1) has an audio source unit, and a multi-channel DSP processor. The DSP processor is designed with eight channels of audio signal processing for forming a sound space in a vehicle interior (10). Each of the above channels is designed with the possibility of adjusting the level and frequency adjustment of the audio signal passing through it using a bandpass filter with an adjustable cutoff frequency and with adjustment of the delay time of the said audio signal. Each of the eight above channels is connected through a digital-to-analog converter to the input of the corresponding output amplifier channel of the above class D power amplifier. The heat-dissipating metal plate is connected by unit of thermal contact connections to each of the electronic amplifying elements of the class D power amplifier, and provided with a dissipating surface area of 150 cm2 and is made of a metal material with a thermal conductivity coefficient no less than that of aluminum. USE - Car radio with multi-channel digital signal processing (DSP) processor. ADVANTAGE - The proposed design of the car radio ensures high sound quality, primarily in terms of guaranteed provision of a sufficiently stable, accurate sound image during the entire period of its operation in the car interior in the range of ambient operating temperatures of specific range. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an organization of test trials of the car radio. 1Car radio with multi-channel digital signal processing processor 6Front dashboard of car 10Vehicle interior 19Multi-channel sound card for testing purposes 20Computer with software for testing trials
