BHI NEDSP1962-KBD - Amplified DSP Noise Canceling Speaker Retrofit Module

The NEDSP1962-KBD Amplified DSP Noise Canceling Module can be retrofitted inside many types of extension speakers or older style radios and transceivers. It incorporates unique Digital Signal Processing (DSP) technology that can identify speech within a noisy signal and can provide up to 40 dB of noise reduction and 65 dB of tone reduction. The module is pre-wired and with a built-in power amplifier allowing it to be easily incorporated into existing equipment. All module functions are controlled by the pre-wired keyboard switch assembly. The NEDSP1962-KBD uses a powerful programmable DSP audio processing chip with DSP noise cancellation technology inside. This high-performance chip delivers exceptional sound quality and incorporates a complete audio signal chain with 16-bit A/D converters and digital interfaces using a fully flexible digital processing architecture. The audio amplifier stage is provided by a Texas Instruments 7W Mono Class-D audio power amplifier chip that has an efficiency of 94%, eliminating the need for heat sinks.
