Specifications: URAL CONCERT CDD Ural Concert CDD (Customizable Digital Device) was developed as a programmable device which is not limited with hardware functionality. The system is focused on opportunity of firmware updating and user\'\'s flexible adjusting of behavioral and sound parameters. This receiver is a multiprocessing embedded system which operates under multitask real time OS control with specific for auto sound application. For today this automobile audio system is one of a few which is capable to transform the incoming radio signal in digital and process it by means of the software. It means absolute protection of noise in uncertain reception conditions. Besides user may use the Encoder\'\'s double pressing to repeat the last 10 seconds of the radio programme. To compensate time loss when playback is rolled 10 seconds back, playback speed is increased (and then is slowly reduced) till synchronization with the programme real time. Each of six sound channels may be separately processed by means of 30 band equalizer as in professional studio. Sound processor allows concentrating sounding in any point inside the car by setting delays for any channel. Besides the electronic antishock has real 17 seconds buffer for audio discs. With the help of the embedded crossover the original signal can be divided into three frequency components, each of which is determined independently by filter types and frequencies settings. In 2003 AAC has received a gold medal for this head unit at one of the most prestigious exhibitions of the technical achievements Brussels - eureka where over forty countries take part every year. Concert CDD also attract attention of many customers on the exhibitions in Hong Kong, Berlin and Seinsheim. By and large, Concert is a computer which operates as a head unit. It is senseless to list all functions of the computer because its functionality depends on the installed firmware version. Updating files may be downloaded from the web site. Record them on CD-R(W) and insert it into the unit. The updating will be proceeded automatically. There is also a video codec program on this web site. It allows transforming digital images to a format. Avi. In this format video clips may be downloaded to the Concert memory and shown on the display. Add here a perfect sound quality provided by 24 bit DAC and ADC, K-line (ISO-9141) for connection to engine control unit and operation also as an onboard/trip computer, six channel internal amplifier, unique control system (encoder) and menu structure, seven line outs (6+Sub line out), line in, wide adjustment abilities and 2 standard stereo decoder and you will see that this head unit probably has the best in the world ratio of price/functionality. And the most important is that Ural Concert CDD has distinctive character.
