ParaPro EQ20-DSP

Adds digital signal processing noise cancellation technology

The ParaPro EQ20-DSP Audio Unit combines parametric equalisation with advanced DSP noise cancellation technology in a compact package, delivering 20W of clear audio. Its sophisticated system allows customisable frequency adjustment from 100Hz to 10kHz with ±10dB adjustment in both bass and treble bands, while the DSP technology reduces background noise by up to 40dB without compromising speech clarity. This powerful unit features user-friendly controls for precise audio customisation and an ultra-low latency of just 38ms, making it ideal for amateur radio, shortwave listening, and commercial radio base stations.

ParaPro EQ20

Base model with parametric equalisation and 20W audio output

The ParaPro EQ20 Audio Unit offers precise audio customisation through powerful parametric equalisation, delivering 20W of enhanced sound. Unlike conventional tone controls, this versatile unit provides dual-band parametric equalisation with ±10dB adjustment from 100Hz to 10kHz, allowing users to target specific frequencies with remarkable precision through intuitive Bass (100Hz-1kHz) and Treble (1kHz-10kHz) controls. The efficient Class-D amplifier provides 10W per channel with ultra-low latency of 38ms.

ParaPro EQ20B

Features parametric equalisation with Bluetooth connectivity

The ParaPro EQ20B Audio Unit enhances the popular EQ20 model by adding Bluetooth connectivity, transforming this 20W parametric equaliser into a wireless audio solution while maintaining its specialised sound customisation capabilities for users with hearing loss. This compact unit delivers precise frequency control through dual-band parametric equalisation, with Bass (100Hz-1kHz) and Treble (1kHz-10kHz) controls offering ±10dB adjustment range, allowing listeners to boost or reduce exactly the frequencies they struggle with for clearer, more intelligible audio. This unit particularly excels when paired with bhi's DSP noise-cancelling units, creating a powerful combination that enhances audio clarity while reducing unwanted background noise.

ParaPro EQ20B-DSP

Premium model combining DSP noise cancelling technology and Bluetooth

The ParaPro EQ20B-DSP Audio Unit represents the flagship model in the ParaPro range, combining parametric equalisation, DSP noise cancellation technology, and Bluetooth connectivity in one comprehensive 20W audio solution. This advanced unit allows users to shape their audio with unprecedented precision using parametric equalisation that provides two bands of ±10dB adjustment from 100Hz through to 10kHz, while our latest dual-channel DSP noise cancelling technology can be adjusted from 9 to 40dB to provide a superior "noise-free" listening experience. The Bluetooth integration on input effectively transforms connected passive speakers into wireless speakers, allowing audio playback from Bluetooth-enabled devices like MP3 players or radios.
