About BHI NEDSP1962-KBD - Amplified DSP Noise Cancelling Retrofit Module

The new NEDSP1962-KBD amplified DSP noise cancelling retrofit module replaces the popular NEDSP1062-KBD, which is now obsolete. The NEDSP1962-KBD can be retrofitted into many amateur radio extension speakers or older style radios (space permitting). The NEDSP1962-KBD incorporates DSP technology that identifies speech in noisy voice signals and can remove the noise to leave clear speech. The module provides up to 40dB of noise reduction over 8 filter levels and up to 65dB of tone reduction. It comes pre-wired and can be easily fitted into existing equipment, with all functions being controlled by a simple keyboard switch assembly.

The NEDSP1962-KBD incorporates DSP noise cancelling technology that makes the processed audio clearer and more intelligible. The module has an onboard 5W Class D type audio amplifier, which is very efficient so no heatsink is required. The module is simply wired inside your extension speaker between the audio input and loudspeaker. It is powered from a suitable 10 to 18V DC power supply and when the module is switched off the audio bypass feature routes the audio signal directly through to the loudspeaker. The pre-wired switch assembly controls all the functions with two pushbuttons and two LED’S indicating the filter level and audio input overload.

The NEDSP1962-KBD is supplied as a pre-wired assembly with a 2.1 mm power socket, audio input and output wires, keyboard switch assembly, full mounting kit with professional labels and user installation manual.

DELIVERY

We aim to dispatch all parcels within 24hrs. We are normally able to dispatch parcels SAME DAY where orders are received before 2.00pm Monday to Friday.

 

Whilst we try our best to ship same day, we cannot guarantee delivery time. You will however receive tracking details as soon as your order has been processed.
