CLRspkr - ClearSpeech® DSP Noise Reduction Speaker
The CLRspkr is a small loudspeaker containing a ClearSpeech® adaptive noise reduction circuit and audio amplifier. It is ideal for mobile radio operation. Noise reduction is superb. The DSP passes the voice and CW sounds, while attenuating noise, such as hum, hiss, static. The process is dynamic and changes with the interference and the signal.
The DSP recognizes the intermittent nature of CW and allows it to pass noise free.
The audio cable plugs into the speaker output on the radio. Connect the powerpoles to any convenient 12 volt supply.
