Great sounding audio! 
The DSPKR comprises a wide frequency range 4” speaker and a 10 watt audio amplifier with built in bhi DSP noise cancelling technology. 

Simple control of the DSP functions
The DSPKR functions are all controlled via the single pushbutton switch on the top of the speaker and the audio output is adjustable via the separate volume control on top of the speaker.

DSP noise cancelling
The DSPKR noise cancelling technology removes unwanted noise and interference to give improved the speech quality for the listener.  There are 8 filter levels allowing you to set the filter level to suit your operating conditions.  The “Status” LED on top of the speaker indicates the current operating mode.

Easy to connect up
The DSPKR has an integrated audio cable with a 3.5mm mono jack plug and connects into the extension speaker socket or headphone socket of your radio, receiver or SDR radio.  It required requires 10 to 16 V DC (1A min) and connection is via the 2.1mm power socket on the rear of the speaker. There is a 3.5mm mono headphone socket on the side.

The DSPKR functions are selectable by using the function button, where you are able to select the filter level, turn the filter on and off and change the sleep mode feature.  The green “Audio Level” LED enables you to optimise the input audio level for the DSP filter.

What’s in the box
The DSPKR is supplied with an integrated 2 metre audio cable with a moulded 3.5mm jack plug, a 2.1mm fused DC power lead with bare ends, a mounting bracket with fixing screws and a full user manual. A 12V DC world-wide mains power adapter is available as an optional extra.

"Beforehand I couldn't listen to lower band HF radio due to plasma TV from two next door neighboours. That changed when I bought your product and now now I can use my radio again, especially in the evening and when tv's are on."
Ian McCallum

"Filters the noise and allows me to concentrate on what I want to listen to.  Thank you."
Alan Garner

"Unit works great, gets interference out very well. Would not be able operate my amateur radio at home location,  I use a Kenwood TS450 HF Tansceiver"
David Digweed VE3FOI

"bhi have a proven pedigree in noise reduction and the DSPKR builds on this to deliver a particularly compact and powerful unit that works well in both mobile and base station applications. The very simple single button operation worked well and the facility to store your favourite setting helped make operation of the DSPKR a real breeze. Noise reduction performance was excellent with useful improvements available over a wide range of listening conditions. The noise reduction settings were particularly well chosen and all were usable under the appropriate conditions"
RadCom Feb '10 Mike Richards G4WNC

I noticed your advertisement in the October edition of Radio User magazine. After carrying out some research via you tube, I purchased from you the DSPKR, which arrived the day after ordering. ( ordered 04/10/2016).  I carried out a test on Shanwick, 5650 KHz, and Volmet military, 5450 KHz, which from my location are radio 2 to 3 stations in terms of audio quality.  The DSPKR increased the audio quality to radio 4 to 5 which in all honesty I was very pleased and surprised at.  Random signals within the 6 MHz band with audio quality around radio 1-2 suddenly became readable with ease.  I am delighted with the product and on that I congratulate your firm.  The DSPKR has transformed my short wave listening hobby to a higher level.  I use the DSPKR in conjunction with a Tecsun S2000 and a random length long wire antenna with a balun.  I would highly recommend this product and personally consider it an essential piece of DX kit.  Research source, YouTube, enter DSPKR, three short videos by Tony M0RIF, UK.
