CLRspkr
Noise Reducing Loudspeaker
Owners Manual
November, 2010
Thank you for purchasing the CLRspkr….. a small loudspeaker containing the “ClearSpeech
®
” noise
reduction circuit and audio amplifier You will find this noise reducing speaker extremely effective in
improving communication clarity. Mobile and base operation is less fatiguing and more fun.
It is ideal for mobile radio operation. Noise reduction is superb. The Digital Signal Processor (DSP)
passes voice and CW sounds, while attenuating noise, such as hum, hiss, whistles, and 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 the 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 headphone or mono 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. Plugging in disconnects the internal speaker.
CLRspkr is a high-tech, low cost solution to enhance the audio quality of communication for ham
radio, mobile operation, car and truck fleets, emergency vehicles, and marine radio.
Choosing a Mounting Location
The CLRspkr may be mounted in any convenient location. It can rest on a tabletop or mount to any
surface. The bracket has two holes for mounting with the included screws. The two side knobs permit
tilt aiming.
Keep the unit close to your radio and power supply. The cables are 6 feet long, but can be
lengthened with extensions, if needed.
Try not to place the unit in direct sunlight. It is black and can get real hot. . .and heat is not the best
thing for electronics. Keep out of rain.
