Stewart Audio DSP 4x4 Digital Signal Processor
Usually arrives in 5-9 business days.
The Alfatron ALF-DSP44-UD 4x4 audio digital signal processor provides 4 analogue and 4 Dante inputs and outputs, 2-channel AEC, USB audio, auto mixing, noise suppression, matrix processing, and flexible DSP control for professional AV and conferencing systems.
The ALF-DSP44-UD is a 4-in/4-out audio digital signal processor with Dante and advanced audio processing capabilities. It features 4 analogue inputs and 4 analogue outputs, 4 Dante inputs and 4 Dante outputs, USB Audio, RS-232, RS-485, and IP control, providing flexible audio management, routing, processing, and control for professional audio systems.
Equipped with two ADI SHARC 21489 processors and advanced processing modules, including 2 channels of Acoustic Echo Cancellation (AEC), noise suppression, auto mixing, and matrix processing. Its input and output processing includes expanders, compressors, Acoustic Gain Compensation (AGC), parametric EQ, feedback suppression, Ambient Noise Compensation (ANC), and delay. The A/D and D/A converters provide 24-bit, 48 kHz audio processing, with a 110 dB dynamic range and maximum level of +24 dBu.
DSP configuration and control are facilitated through the Alfatron DSP controller, a Windows-based software application for setting parameters, configuring DSP modules, and managing RS-232, RS-485, and other peripheral settings. The software also provides a customizable user interface that allows integrators and engineers to define accessible controls for on-site technicians and end users, with security features that restrict access to designated functions.
Most Alfatron products come with a 7-year limited warranty. Register your product with Alfatron to receive an additional 3-year extended warranty on eligible products, for 10 years of total coverage.
