Thank you for choosing the CLRspkr ClearSpeech
®
Digital Signal
Processor Noise Reduction Speaker. The CLRspkr connects
directly to the radio. The unit is extremely effective in improving
communication clarity. QSO’s will be more enjoyable without
the fatigue of background noise. In many cases, there will be a
noticeable improvement in understanding weaker signals, making
contacts, and general listening.
CLRspkr is ideal for mobile radio operation as noise reduction is
superb due to the Digital Signal Processor (DSP) passing voice and
CW sounds, while attenuating noise, such as atmospheric noise,
hum, hiss, whistles, and static. It effectively removes heterodynes,
ignition noise, lightening crashes, power line noise. The process is
dynamic and changes with the interference and the signal, but the
effect is rewarding. Mobile voice operation is more fun without all
the background noise. The DSP recognizes the intermittent nature
of CW and allows it to pass noise free.
CLRspkr may be mounted in any convenient location. The bracket
permits tilt aiming. The included 6ft. audio cable plugs into the
headphone or mono speaker output on the radio. The unit also
includes a 6ft. power cable with Powerpole connectors that will
plug into a 13.8 volt supply. Extension cables available separately.
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. The CLRspkr
works well in the home station as well.
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. This unit is not weather resistant and suggested
to use in a dry place out of direct sunlight.
