Product Description

Product Description

The dB-NET series digital audio processor is a freely designed audio processing and control system. It uses advanced DSP processing technology, with a new automatic mixing, feedback elimination algorithm, targeted to solve the application of the various practical problems in the scene. Because most of the control through the software operation, so the appearance can be more concise and lively. The operator simply click the next mouse, no longer as in the past, in the field to adjust the complex large-scale mixer to complete the function conversion, greatly simplifying the operational difficulty.
The processor family is a family of complex audio signals that use a built-in DSP chip that uses a standard 48KHz / 24bit (up to 192KHz / 32bit) high quality A / D and D / A converter for multi-channel analog Signal and digital signal interchange, the use of industry-leading Texas Instruments TI core processing chip (450MHz Flops), the balance, delay, matrix mixing and other conventional functions at ease, more built-in efficient audio algorithm, the main solution to the whistle, echo , Noise and other applications in the difficult problems.
