Precise audio adjustment for your own hearing
The bhi ParaPro EQ20B-DSP 20 watt audio unit comes with parametric equalisation, bhi's world-class DSP noise cancelling technology and Bluetooth. The parametric equalisation allows you to fine-tune the sound of your audio and boost or cut the frequencies to suit your own hearing and conditions.
Latest bhi DSP Noise cancelling Technology
The EQ20B-DSP unit features a 10W per channel audio amplifier with Bluetooth, 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
You can connect one or two mono inputs to the CH1 and CH2 input sockets, or a stereo signal from an SDR radio, shortwave receiver, MP3 player etc, via the stereo input socket.
Choice of outputs and connections
Connect passive speakers to the left and right “Speaker Outputs” using the 4mm banana plugs or phono to 3.5mm mono adapters supplied. Use the “Source Select” button on the front panel to select the desired audio.
Easy to use audio controls
The EQ20B-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 fully adaptive DSP noise cancelling filter can be adjusted from to 9 to 40dB enabling you to change the filter setting in "real time" to suit your current conditions.
Benefits of Parametric Equalisation
Unlike standard tone controls, graphic equalisation and preset EQ settings a parametric equaliser allows you to select the precise frequency you want to adjust. This enables you to boost or cut the selected frequency giving you much greater flexibility and accuracy in setting the audio to suit your own hearing. This is especially beneficial to people with hearing loss.
Built-in Bluetooth connectivity on the input effectively turns the EQ20B-DSP into a Bluetooth speaker allowing audio playback through the unit from a Bluetooth audio source like an MP3 player or Bluetooth enabled radio.

"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.
