Low level audio DSP noise cancelling module - Works across whole audio bandwidth! DISCONTINUED REPLACED BY NEDSP1901-KBD Now available click here
This DSP noise cancelling module works across the whole audio bandwidth and is able to separate the speech signals from the noise giving you excellent processed audio depending on which filter level you require. It isn't a simple noise extraction system or bandpass filter system which can affect the processed audio quality.
Pre-wired audio DSP noise cancelling module Integrates directly into the low level audio path of your receiver, transceiver or audio system, giving you excellent DSP noise cancellation and greatly improve speech quality. The module features DSP ON/OFF and up to 8 levels of DSP filtering via a small pushbutton interface keyboard. The module is supplied with general installation instructions plus specific fitting guides for the Yaesu FT-817, Kenwood TS-50 and Icom 706 MK II G. There are also 3rd party instructions available in the "Amateur Radio Installs" section for the Yaesu FT-847, FT-897, FRG100, Realistic DX-394, Alinco DX-77 and the Kenwood TS440. Other radios can also benefit from this module. contact us for more information. The module can also be used to enable a quick evaluation of the noise cancelling properties for commercial applications when considering the basic NEDSP1061-PCB module. This DSP noise cancelling module works across the whole audio bandwidth and is able to separate the speech signals from the noise giving you excellent processed audio depending on which filter level you require. It isn't a simple noise extractor system which can affect the processed audio quality.
Just four wires are used to connect the module in circuit: Audio In, Audio out, 0V and Power. All that's left to do is drill holes to accommodate the switch assembly and label. Fitting kit supplied.
Adjustable Level controls are provided for input level and audio output level. The module features an overload LED on the audio input to give visual indication of the correct signal level.The volume level of the beeper can be adjusted to suit.

"Excellent! I recently purchased the bhi DSPKR for my icom 706 radio and Wow! It's like listening to FM on HF. I also had the bhi "internal" filter installed by W4RT on my new Yaesu FT-897D & LOVE IT! (11-14-14). Looks great & looks like a factory upgrade! I love this DSP filter" Danny Garris
