Parasound nye Ultra-High-End monoforsterker

JC 1+ er Parasound sin nye høyeffektive mono effektforsterker. Det å lage en forsterker som er i stand til å fremkalle den aller beste ytelsen fra de fineste høyttalerne, og samtidig overgå konkurentene med langt høyere pris, gjør JC 1+ til Parasounds mest ambisiøse product til nå. Parasound rekrutterte nok en gang et design team ledet av den legendariske lyddesigneren, John Curl. Mannen med initialene «JC» star bak selskapets kritikerroste og kjente JC 1, JC 2BP, JC 3+, JC 3 Jr.

Med en kraftleveranse på 450 watt RMS til 8 ohm, 850 watt RMS til 4 ohm, og 1.300 watt RMS ned til 2 ohm – sammen med en topp strømkapasitet på 180 ampere, fremkaller JC 1+ fantastisk ytelse fra de fleste høyttalerne. De første 25+ watt i ren klasse A vil virkelig få høyttalerne dine til å synge.

This is a superb-sounding amplifier that will get the best from every loudspeaker with which it is partnered. Well done, Mr. Curl.
