Parasound - John Curl HALO Series JC1+ - Monoblock Power Amplifier (Each)
JC1+ by John Curl and Parasound
The Halo JC 1+ is an uncompromising mono power amplifier that sets new standards in power and fidelity. With 450 watts at 8 Ω and 850 watts at 4 Ω, it delivers exceptional audio performance. The balanced XLR and unbalanced RCA inputs ensure compatibility with various audio sources. Its dual-mono design with two transformers provides exceptional channel separation and sonic accuracy. The direct-coupled design, without capacitors in the signal path, preserves signal integrity and enhances transparency. Experience unparalleled power and fidelity with the Halo JC 1+ mono power amplifier.
