bhi ParaPro EQ20-DSP with Bluetooth Installed

Shape the audio to suit your ears!
Professional Grade Audio Equalisation for Amateur Radio

The new bhi ParaPro EQ20B-DSP features a 20W modular audio power amplifier with a parametric equalizer and bhi’s latest dual Channel DSP Noise Cancelling technology. The parametric equalizer 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 EQ20B-DSP unit utilizes the latest bhi dual channel DSP noise-canceling technology, which can handle mono or stereo signals and has an improved noise suppression algorithm that gives improved speech quality to the listener. The processed speech is clearer and more intelligible even with weak signals and at higher noise levels. Bluetooth connectivity enables input from a Bluetooth source which effectively turns the EQ20B-DSP into a Bluetooth speaker.

The EQ20B-DSP 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 EQ20B-DSP has two parametric channels labeled Bass and Treble with the Bass center 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 parametric equalizer 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 equalization is applied. The most important feature of a parametric equalizer is that it allows you to select which frequency to adjust. For example, instead of having a simple mid-range adjustment as in a standard graphic equalizer which boosts or reduces a pre-set range of frequencies, you can specify exactly which frequency to boost or reduce. This gives you greater flexibility and accuracy to set the audio to suit your own hearing.
