AB-1004

 

AB-1004 is another digital signal processor that provide multiple functions in one unit. One unique features of AB-1004 is that it has a built-in PC control software that allow users to use the built in Windows platform in the processor to control the processor, network can also be downloaded. Besides, IOS platform control software has also been launched, making it suitable for people from both platform without the process of learning a new UI.

Multiple Built-In Algorithm

3 Built-In Processing Algorithm

AB-1004 has built-in echo cancellation, feedback suppression and noise algorithm. It uses the stable Double Talk detection method, the redundant echo can be effectively eliminated even in the environment of strong background noise and nonlinear distortion. The noise suppression algorithm can track the environmental noise changes quickly and accurately and maintain good output sound quality.

 

Varies Input Signal Interface and Adjustment Module

10 Input Signal Interfaces

For AB-1004, there are a total of 10 input signal interfaces, 8 channels MIC input and two channels input. For signal output, there are four channels output are provided.

Full-Function Audio Adjustment Module

Support gain adjustment, 48V phantom power supply, built-in front-stage amplifier, signal generator, expander, compressor, 5-section parameter equalization, 31-section graphic equalization, delay controller, frequency divider, limiter and other functional modules.

Built-In PC Control Software

Windows

Processor built-in Windows platform control software, network can be downloaded and installed, software design simple and practical.

IOS

IOS platform control software has also been launched, and the function experience is constantly being optimized. In addition, web page control is still supported to provide users with more free testing, debugging experience.
