Dec sale now on!
Give your receive audio the boost it deserves!
The bhi ParaPro EQ20-DSP amplified DSP noise cancellation unit with parametric equalisation allows you to customise the sound of your received audio and control which frequencies you want to boost or cut to suit your own hearing.
Latest bhi DSP noise cancelling technology
The EQ20-DSP unit features a 10W per channel audio amplifier with parametric equalisation and bhi’s latest dual Channel DSP noise cancelling technology to give you an even better "noise free" listening experience.
Mono or stereo inputs
The unit has two mono input sockets enabling you to connect up to two radios to the CH1 and CH2 input sockets respectively, or connection of a single stereo signal from an SDR radio, shortwave receiver, MP3 player etc, via the stereo input socket.
Choice of outputs and connections
Connect a single 4/8 ohm passive speaker or a pair of passive speakers to the left and right “Speaker Outputs” using the supplied banana plugs or 3.5mm plug to phono adapters. Use the “Source Select” button on the front panel to select the desired audio.
Easy to use controls
The EQ20-DSP is housed in a quality compact ABS case. There are controls for Power/Volume along with two parametric equaliser channels labelled Bass and Treble, with the Bass centre frequency being adjustable from 100Hz to1kHz and Treble covering 1kHz to 10kHz. Used together these controls provide two bands of ±10dB adjustment from 100Hz through to10kHz. bhi DSP noise cancelling. The bhi noise filter control allows you to adjust the filter level from off (DSP bypassed) to 40dB of noise cancellation.
Parametric equalisation allows any specific part of the frequency range to be selected and adjusted. The most important feature is that it allows you to select which frequency to adjust. You can specify exactly which frequency to boost or reduce giving you greater flexibility and accuracy in setting the audio to suit your own hearing. This is especially beneficial to people with hearing loss.

"I have a Dual In-line module which is very good for eliminating noise. The EQ20B-DSP is first class and really does improve the audio and noise cancelling signals can be fine tuned. I am now hearing all calls much clearer. Heavy accents are no longer a problem" EQ20B-DSP review by Peter Joyner M0WPJ
"Using the new EQ20-DSP noise cancelling and parametric equaliser for a few days I have found this to be an excellent purchase. I am now able to receive stations down in my local noise level which was not possible before due to high solar panel and other local electronic noise. Using the fixed line level output from my ICOM IC7600 and IC9100 transceivers thus bypassing the internal audio stages gives the best results.( 4.7K 300mV rms )this source is just below the clipping level, the audio having little or no distortion with a frequency range to suit me. Many thanks to Kellie and Graham for the very fast and efficient service." Best Wishes David G2FT ex G3MWV.
