The bhi DESKTOP “DSP noise cancelling base station speaker ” is designed to greatly improve the speech quality of noisy radio communication channels, especially amateur radio, two-way radio, HF radio and SDR radio. The new rotary volume and filter controls make it very easy to use and it is suitable for all bands. The speaker comprises a 4" bass driver and 1" tweeter unit with a 10 watt DSP noise cancelling unit. The DESKTOP speaker can also be connected to a stereo line level input signal, or to a speaker level audio signal. There are audio tones for both the volume control and filter levels, plus audio overload indication. There is a 3.5mm headphone socket that will take either mono or stereo headphones. It comes with a metal mounting bracket that can be left on or removed depending on personal choice, a 1.2 meter audio cable with a molded 3.5mm jack plug and banana plugs plus a 2.1mm fused DC power lead and user manual


I have sometimes been a little sceptical about DSP noise cancellation, but this really does reduce noise very effectively without any annoying and distracting DSP artefacts

Transformed the output sound of my TS-930S providing as clear audio to match current rigs.
