Shape your receive audio to suit your ears!

Professional Grade Audio Equalisation for Your Receive Audio

The new bhi ParaPro EQ20 features a 20W modular audio power amplifier with a parametric equaliser.  The parametric equaliser allows any specific part of the frequency range to be selected and adjusted in strength enabling the user to shape the audio to suit their ears.  

The EQ20 unit is housed in a quality compact ABS case measuring. It is easy to integrate with a number of different connection options available. Features include separate mono and stereo inputs for line level, headphone level and speaker level signals. The LED will flash if the input is overloaded. The outputs comprise a set of banana sockets for the left and right speakers plus a pair of RCA phono jacks for the speaker outputs. Important Note:  The Class D bridge output has a direct DC connection to the amplifier circuitry (i.e. no isolating capacitors) so you must not parallel the speaker outputs or ground any of the connections.  Stereo headphones can be connected from the front of the unit.  The EQ20 has two parametric channels labelled Bass and Treble with the Bass centre frequency being adjustable from 100Hz to 1kHz, whilst the Treble covers 1kHz to 10kHz. Used together, these controls provide two bands of ±10dB adjustment from 100Hz through to 10kHz. The bhi DSP Noise Filter in the is continuously variable from off (DSP bypassed) up to 40dB of noise cancellation. 

Parametric Equalisation:   A standard graphic equaliser usually splits the audio spectrum into several fixed bands and provides lift and cut adjustment for each frequency band. However, the controls usually interact so if you lift one band you will often find that the adjacent bands are also lifted but to a lesser degree. A parametric equaliser allows any specific part of the frequency range to be selected and adjusted in strength. The user is able to adjust these parameters to determine exactly how the equalisation is applied allowing you to specify exactly which frequency to boost or reduce. This gives you much greater control and enables you to customise the sound of your audio to suit your own hearing.

The ParaPro EQ20 unit is ideal for use with the bhi Dual In-Line, Compact In-Line and NEIM1031MKII units. It can also be used with the bhi DESKTOP & DSPKR noise cancelling speakers via the headphone socket on the front.

Testimonial "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 Kelly and Graham for the very fast and efficient service." Best Wishes David G2FT ex G3MWV.
