Overview

bhi DSP Devices

bhi Dual In-Line DSP Noise Eliminating Modules provide two-channel or stereo noise cancellation, and are suitable for use on all receivers and transceivers, including SDR. They are especially applicable with stereo or two channel output options. They may also be used with monaural speaker input and output signals providing up to 7 watts of audio when a mono speaker is connected.

bhi Dual In-Line modules incorporate their latest DSP noise cancelling technology. This method has an improved noise cancelling algorithm that brings even better quality audio to the listener when operating in very noisy conditions. The processed speech is clearer and more intelligible which makes your listening experience so much better.

These modules cater to both high and medium level mono and stereo audio input signals, and have stereo line out, stereo headphone and mono speaker output jacks. You can listen with headphones and a monaural speaker at the same time, and you can also connect a pair of stereo computer speakers to the line output jack allowing you to monitor two separate channels at the same time. This feature is ideal for DXing, SO2R, club stations, training, special event stations and Field Day events.
