Description
Alfatron DSP44-U
The Alfatron ALF-DSP44-U Audio Digital Signal Processor (DSP) is equipped with several core technical features to simulate the work of an audio engineer. The ALF-DSP44-U consists of 4 analogue inputs and 4 analogue outputs, USB Audio, RS-232, RS-485, and IP control. With one ADI SHARC 21489 processor, it is equipped with advanced audio processing modules including Acoustic Echo Cancellation (2 Channels), Noise Suppression, and Auto Mixing. The Analogue to Digital (A/D) and Digital to Analogue (D/A) convertors on the Input and output stage of the ALF-DSP44-U features 48kHz sampling rate and a bit rate of 24Bits, providing high definition audio sampling and processing. It also has a dynamic range of 110dB and a maximum level of +24dBu. It features input and output processing modules including: Expanders, Compressors, Acoustic Gain Compensation (AGC), Parametric EQ, Feedback Suppression, Automatic Noise Supression(ANC) and Delay. DSP-based audio management, routing, processing, and control, is facilitated via a computer running the GUI Software for the ALF-DSP44-U Hardware. The Alfatron DSP Controller software is a Windows-based application, which is used to configure and control the ALF-DSP44-U. The Alfatron DSP Controller is a full-feature application, including parameter adjustments and peripheral accessory settings of all modules, such as RS232, RS485, and click-and-drag panel configuration. The most interesting part is the user interface which allows the engineer to customize the user interface so that the integrator can edit it; or the onsite technicians, or end users can operate it. Advanced security features make it possible for the end user to only access the controls allowed by the engineer, or the designer.
