BHI Dual In-Line DSP Noise Cancelling Unit, Stereo, 8 Filter Levels, 7W

The BHI Dual In-Line DSP noise cancelling module delivers two-channel stereo noise elimination for all radios and receivers — including SDR — with an improved algorithm that produces clearer, more intelligible speech even in very noisy conditions.

It accepts both high and medium level mono and stereo audio input signals, and offers stereo line out, stereo headphone, and mono speaker outputs simultaneously. You can listen on headphones and a mono speaker at the same time, or connect stereo computer speakers to the line output to monitor two separate channels in parallel — ideal for DXing, club stations, training, special event stations, and field day events.
