The bhi DESKTOP 10 watt DSP noise cancelling base station speaker will work with most radios, transceivers, receivers, and SDR radios, giving a new listening experience. The new rotary controls make it very easy to use and set up to your own operating conditions.
The DESKTOP speaker comprises a 4" bass driver and a 1" tweeter unit with an amplified bhi DSP noise cancelling unit capable of producing up to 10 Watts audio (peak). There are rotary controls on the side of the speaker for volume and filter level control.
The DESKTOP speaker can be connected to a stereo line level audio input signal, or to a standard speaker level audio signal from an extension speaker socket. There is a 3.5mm headphone socket below the controls that can accept either a 3.5mm mono or stereo jack plug.
The speaker is supplied with a quality 1.2 metre audio cable with a moulded 3.5mm jack plug on one end and 4mm banana plugs on the other, as well as a 2.1mm fused DC power lead and user manual.

Note: Elecraft K3 users: To connect to the K3 using the speaker lead supplied you need to either make up an audio lead with a 3.5mm stereo plug (tip only connected) to a 3.5mm mono socket, or purchase one of our ALD-009 leads, or alternatively use a 3.5mm stereo plug to plug lead and connect from your K3 to the line in socket on the DESKTOP speaker (ALD-007).
“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...”
RadCom Jan ‘14 review
“Transformed the output sound of my TS-930S providing as clear audio to match current rigs.”
Mr. B Hiley:
“The DESKTOP speaker is great, audio is crisp and clear, brilliant!”
“I just wanted to thank you for your amazing Desktop (10W) DSP Speaker. I bought it from you @ the Kempton Park Rally - I tried it for the 1st time this Sunday on a noisy 40m band and was gobsmacked! Your unit made a fine job eliminating the crud picked up by the radio. I now consider your noise eliminating speaker an essential bit of kit in my ham shack! Thank you very very much.” John G1WVN.
