The NEDSP1068-PCBA is a small PCB module with an on-board AGC microphone preamplifier with DSP noise cancellation technology.  It is designed to clean up noisy voice communications, where the processed speech becomes much clearer and more intelligible for the receiving person, enabling stress free voice communication. The module can easily be wired or connected to a microphone.

The module has has an adjustable AGC microphone pre-amplifier circuit, and is able to operate with external electret and dynamic microphones. It can be wired in-line with the target audio system or mounted onto a motherboard using 0.1” pitch PCB connections.

This module is very useful for cleaning up the audio in noisy voice communications systems, like hands free intercoms, crane intercoms, industrial intercoms, pit to car race communications, transport communications, marine communications, in fact anywhere where you are communicating from a noisy environment.

The NEDSP1068-PCBA-MIC version is also available.  This model incorporates an onboard Knowles SMD microphone, and is suited to static locations where it can easily be wired into the target audio path.
