This compact speaker system utilizes powerful digital signal processing (DSP) to suppress annoying background hiss and static, revealing crisp, clean audio for shortwave reception, scanner monitoring, ham radio transceivers, CB installations, maritime mobile, noisy recordings, and other sources of crackly, hiss-ridden audio.

This passive (no power required) external speaker offers four high- and low-pass push button selections to improve audio quality on any receiver, transceiver or scanner. Reduces shrillness or high-pitched heterodyne interference as well as boominess on audio signals. Contour recovered audio for best reception.

Whether your mobile listening needs are for scanner, shortwave, ham radio, CB, or professional two-way communications, this mobile accessory speaker will improve audio reception.

 Now you can listen to your favorite shortwave, talk radio, music broadcast, scanner activity, anytime you want by pre-recording the transmissions--at normal tape speeds or up to four hours on one side of a standard 120 minute cassette.
