Understanding the ParaPro EQ20-DSP Series

At the heart of the ParaPro EQ20-DSP series lies a sophisticated audio unit that seamlessly integrates parametric equalisation with powerful DSP noise-cancelling technology. With 20 watts of audio power, these units offer a significant boost in audio clarity, making them ideal for individuals seeking an optimal listening experience.

Parametric Equalisation: Precision Tailoring for Individual Needs

One standout feature of the EQ20-DSP series is its parametric equalisation capabilities. Unlike traditional tone control or preset EQ settings, the parametric equaliser allows users to select precise frequencies for adjustment. This level of customisation proves invaluable, particularly for individuals with hearing loss.

The EQ20-DSP provides two parametric equaliser channels labelled Bass and Treble. Users can fine-tune the sound by adjusting the centre frequency from 100Hz to 10kHz. The ±10dB attenuation adjustment in these bands ensures a tailored audio experience that caters to individual preferences.

DSP Noise Cancelling: Unravelling the Technology

bhi's DSP noise-cancelling technology is the star of the show, setting the EQ20-DSP series apart from conventional audio solutions. The unit's 10W per channel audio amplifier, combined with parametric equalisation and dual channel DSP noise cancelling technology, creates a powerful audio processing system.

The DSP noise cancelling algorithm distinguishes speech from background noise across the entire audio bandwidth. The result is clear, intelligible speech even in challenging environments, offering users the opportunity to shape the audio to suit their hearing.

Versatility Redefined: Inputs, Outputs, and Connectivity

The EQ20-DSP series boasts versatility in its connectivity options. Users can connect one or two mono inputs to the CH1 and CH2 input sockets or a single stereo signal via the 3.5mm stereo input socket. Whether you're using it with a radio transceiver, SDR radio, shortwave receiver, or an MP3 player, the EQ20-DSP adapts to your audio source.

The choice of outputs and connections adds to its flexibility. Connect one or two passive speakers to the left and right speaker outputs using 4mm banana plugs or RCA phono to 3.5mm mono adapters. The "Source Select" button on the front panel allows easy switching between audio sources.

User-Friendly Controls and Testimonials

Navigating the EQ20-DSP is a breeze with its easy-to-use controls housed in a compact ABS case. The front panel features controls for Power/Volume, parametric equaliser channels for Bass and Treble, and a bhi noise filter control for adjusting noise cancellation levels up to 40dB.

User testimonials speak volumes about the product's impact on audio clarity:

"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" - 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." - David G2FT ex G3MWV.
