bhi ParaPro EQ20B-DSP DSP with Bluetooth
2 × 10 W audio unit with 9–40 dB DSP noise cancelling, parametric equalisation and Bluetooth input
The bhi ParaPro EQ20B-DSP is a 20 W (10 W per channel) audio unit with bhi dual-channel DSP noise cancelling, parametric equalisation and Bluetooth input.
Product description
One or two mono inputs can be connected to the CH1 and CH2 sockets, or a stereo signal from an SDR, shortwave receiver or MP3 player via the 3.5 mm stereo socket. The Source Select button on the front panel selects the source.
Passive 4 or 8 Ω speakers connect to the left and right outputs with 4 mm banana plugs or with the supplied 3.5 mm phono-mono adapters. There is also a 3.5 mm stereo headphone output.
The two parametric equalisation channels, Bass (100 Hz–1 kHz) and Treble (1–10 kHz), each adjust ±10 dB at the chosen frequency. Unlike ordinary tone controls, the parametric equaliser lets you act precisely on the desired frequency: a great help for those with hearing problems.
The fully adaptive DSP filter adjusts from 9 to 40 dB in real time. The Bluetooth input turns the unit into a Bluetooth speaker: audio from an MP3 player or a Bluetooth-enabled radio plays through the connected passive speakers.
Key features
Playback from wireless sources.
Dual channel, adaptive.
Ideal for those with hearing problems.
Note
Bluetooth works on the input only: to connect Bluetooth headphones, speakers or hearing aids to the output, an external Bluetooth transmitter is required.
