High Current Amp! fiers

JCAIaSSSA

Parasounds High Current Amplifiers offer explosive power with uncompromised sound quality. Our focus
on a high current/high bias design influenced by John Curl, utilizes complimentary discrete circuitry to assure
every watt is crystal clear and available for crisp vocals, magnificent explosions, and dynamic music. Every
amplifier features I2 volt triggers, gain controls. and bullet-proof protection for ease of use and peace of mind.

Give us the most demanding music or the most action packed soundtrack, and you will love what you hear.
