The Parasound Halo JC 1+ is remarkably quiet and is the first commercially built product to employ active high-frequency noise filtering with Bybee Music Rails, eliminating input stage noise that compromises sound quality. Curl’s newly-designed driver stage employs a cascode circuit with greater open-loop bandwidth and increased linearity. In another first for the JC 1+, the input and driver stages reside on FR-408 printed circuit board material. Until now FR408 was used in super-computer and aerospace applications. The input-stage power supply is totally independent from the main power supply. Its R-core transformer isolates sensitive circuitry from high-frequency power line noise. This input stage power supply employs quiet high speed/soft recovery diodes and 22,400 uF filter capacitance, to deliver +/- 112 VDC rail voltage, virtually eliminating distortion. Premium Wilson Audio REL capacitors use a proprietary design, which resists micro vibrations that typically degrade the sound quality of other caps. The addition of an XLR Loop Out as well as a 12V-trigger/delayed-turn-on improve the connectivity and utility when multiple JC 1+s are used in bi, tri, and quad amp configurations.
