Ooberpad proudly presents to you Parasound Halo JC 1+ Monoblock Power Amplifier by John Curl. Five years in development, the new JC 1+ monoblock amplifier is the best-in-class outcome of Parasound and the iconic designer John Curl. Voltage drops occur when the power transformer, bridge diodes and filter capacitors aren’t significant. The original JC 1 circumvented voltages drops by equipping its power transformer with additional secondary windings only for the input and driver stage power supply. The Halo JC 1+ goes a notch better with the addition of a separate power transformer dedicated to the input and driver stages. This second power transformer supplies ± 89V to high-speed soft-recovery bridge diodes and Nichicon filter capacitors totalling 22,400uF, resulting in rock-solid ±112Vdc for the B+ and B- “rails” when the amplifier’s output stage is functioning at its optimal capacity.

Benefits of Parasound Halo JC 1+ Monoblock Power Amplifier by John Curl

Ingenious and Noise-Free

High Current is Imperative for High Performance

Curl endearingly referred to the JC 1 as a “stump puller” because its 135 amp peak current enabled it to drive any commercially manufactured speaker with ease. Over the years, he has observed an increasing number of high-performance speaker manufacturers employ lower impedance to achieve their sonic objectives. Impedance dips below 2 ohms are very commonplace. Such excruciatingly low impedances level up an amplifier’s odd higher-order harmonic distortion, a primary cause of listening boredom or fatigue. Driving low impedance speakers doesn’t always require more watts, but the higher current is imperative

Parasound raised the JC 1+ peak current 33% to 180 amps with the addition of six Sanken 15A/230V/60Mz bipolar output transistors, for a total of 24. Accommodating six more output devices necessitated changing the output stage circuit board’s orientation from horizontal to vertical. This added welcome benefits of more effective heat dissipation and easier serviceability. To conduct higher current flow in the JC 1+ we made the copper traces on its main circuit board and N and P channel output stage circuit boards twice as thick as on the JC 1.

Nuanced Performance with High Signal to Noise Ratio

Audio signals inside the JC 1+ travel from the input/driver board to the mainboard via shielded oxygen-free copper interconnects with 24k gold-plated connectors for optimum signal integrity and long-term resistance to corrosion. Strategically routing each internal wire further contributes to its exceptionally high signal-to-noise ratio.
