NEDSP1962-PCB Amplified DSP Noise Cancelling PCB Module
(£108.29 excl VAT)
New. The NEDSP1962-PCB is an advanced amplified DSP noise cancelling retrofit PCB module designed to dramatically improve sound quality in challenging acoustic environments.
- Powerful Digital Signal Processing (DSP) technology with up to 40 dB noise reduction
- Integrated 7W on-board power amplifier for enhanced audio performance
- Versatile retrofit design compatible with extension speakers and intercom systems
- Easy-to-install module with standard 0.1" (2.54 mm) pitch connector spacings
- High-efficiency Texas Instruments Class-D audio amplifier (94% efficient)
- Exceptional noise and heterodyne tone reduction up to 65 dB
- Dimensions: 70mm x 50mm x 15mm
The NEDSP1962-PCB is a modular solution for noise reduction in communication systems. By leveraging advanced digital signal processing technology, this compact module can transform marginal audio environments into clear, intelligible soundscapes. The device's core strength lies in its ability to identify and isolate speech signals within noisy backgrounds, making it invaluable for applications where crystal-clear communication is critical.
At the heart of the module is a powerful, programmable DSP audio processing chip that delivers exceptional sound quality. Featuring 16-bit A/D converters and a fully flexible digital processing architecture, the NEDSP1962-PCB ensures that every nuance of audio is captured and refined. The integrated Texas Instruments 7W Mono Class-D audio power amplifier provides robust sound output with remarkable energy efficiency, eliminating the need for bulky heatsinks and making the module ideal for space-constrained installations.
Connections to the module are made via connection pads down either side of the PCB. These pads are in 0.1” (2.54 mm) pitch connector spacings, which allows the use of standard pin headers, PCB connectors or direct wiring. The connector positioning has been made such that the module may be ‘Plugged’ into a motherboard as part of a larger system.
With its versatile design, the NEDSP1962-PCB can be easily incorporated into existing audio equipment, offering a straightforward retrofit solution for improving speech intelligibility. Whether you're upgrading communication systems, enhancing intercom performance, or seeking to reduce background noise in challenging acoustic environments, this module provides a professional-grade solution that combines advanced technology with user-friendly implementation.

We endeavour to dispatch all orders received before 2:00 pm the same day.
We kindly advise that orders placed on Fridays may be processed the next working day, with dispatch most likely taking place on Monday.
Standard shipping method worldwide is Royal Mail up to 2kg. For orders over 2kg we use a parcel courier service for the UK, and a European road service for Europe. See our shipping rates & table for more information on our shipping rates.
EU customers: You are no longer charged the 20% UK VAT on your orders as a result of Brexit. Be aware that you are likely to be charged import taxes and/or duties by your own tax authorities and an administration fee by the parcel delivery company on any goods you purchase from us in the UK. But remember, you didn’t pay the 20% UK VAT on your order.
Additional charges are the responsibility of the recipient because we have no control over these government-imposed charges and cannot determine what they may be. Customs policies vary greatly among countries. Please contact your local customs office for information.
