CLRspkr - DSP Noise Reduction Speaker &
CLRdsp DSP Noise Reduction Processor
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, whistles, static. It effectively removes heterodynes, ignition noise, lightening crashes, power line noise, and hum. The process is dynamic and changes with the interference and the signal, but the effect is rewarding. Mobile voice operation is fun without all that background noise.
The DSP recognizes the intermittent nature of CW and allows it to pass noise free.
The CLRspkr may be mounted in any convenient location. The bracket permits tilt aiming. Its audio cable plugs into the speaker output on the radio. Connect the powerpoles to any convenient 12 volt supply. The 6 foot cables may be lengthened with extensions, if needed.
The CLRspkr works well in the home station too. There is a 1/8 inch phone jack on the back for connection to an external 8 or 4 ohm loudspeaker. This disconnects the internal speaker.
The CLRdsp has all the same DSP features of the CLRspkr but without a speaker. You supply a speaker or you can plug in your headphones.
