CLRspkr ClearSpeech™ DSP Noise Reduction Speaker
The CLRspkr is a compact, portable loudspeaker containing an adaptive DSP noise reduction circuit with a 10W audio amplifier. The ClearSpeech™ adaptive DSP algorithms analyze the noise content of the incoming signal, then greatly attenuate or completely remove hum, hiss, ignition and power line noise, static and heterodynes. What you hear is clean voice and CW, with over 85% of the noise removed.
The new volume control knob allows users to adjust audio volume for easy listening. This allows the radio's receive sound level to be optimized for other uses such as interfacing to a West Mountain Radio RIGblaster sound card interface. Relocating the external headphone jack to the front of the unit makes it even easier for users to experience noise free sound through their favorite speakers or headphones.
