High Current Amplifiers

Parasound’s 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. Each amplifier

features 12 volt DC 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.
