DP professional audio digital processor

Product overview:

        When we need to do a good set of electro-acoustic sound amplification system, it must be better audio signal processor, signal processor performance is mainly reflected in good timbre effect, sound reduction degree is higher, operation is more simple and easy to understand, product device requirements are higher to achieve the noise suppression effect of the device itself.Therefore, our technical team, in cooperation with cutting-edge technical personnel in the industry, innovatively developed and produced the audio digital processor products of i.E.voice brand trademark according to the inherent characteristics of our high-quality neodymium magnetic coaxial speakers, and preset the product categories with different functions according to the purposes of different sound field environments:

                             DP206=2+6（in+out）                  DP306=3+6（in+out）

                             DP404=4+4（in+out）                  DP408=4+8（in+out）

Product features:

       Product signal processing based on DSP digital audio processing chip technology, adopt the 96 k frequency sampling mode, system design enough information storage space, you can be preset stored 50 groups of different use function environment demand model of sound field scene, to play your strong professional technical ability, fine 1 u case design, at the same time have the remote control port (USB, RS232 and RS485) to meet other cities or the third party central control system of the system control function.For better security, you can use our multi-option security lock to ensure that your system information is not lost.
