Additional details
Audio signals inside the JC 1+ travel from the input/driver board to the main board 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.
This rear panel is all business
As in the JC 1, there is a two-position toggle switch to select normal bias and 25 watts in pure Class A or lower bias
and 10 watts in pure Class A. The purpose of this switch is to reduce the temperature of the JC 1+ with a barely
perceptible effect on sound quality.
New to the JC 1+ is a two-position toggle switch to select gain of 29dB or 23dB. This can minimize residual noise if you
have a high-gain line stage preamp with a “hair trigger” volume control and / or high sensitivity loudspeakers.
The JC 1+ auto turn-on circuit is designed with greater
audio sensitivity so the JC 1+ won’t turn off during
extended quiet musical passages. Also new is a
heavy-duty AC master power switch for when you’re
away for business or pleasure.
Our proprietary 24k gold-plated spinner style speaker
terminals accept banana plugs, up to 16 mm wide
spade lugs, and up to 5-AWG bare speaker wire. We
provide two pairs of speaker terminals as a
convenience if you’re already bi-wiring your speakers
or might try this in the future.
The JC 1+ employs balanced Neutrik locking-type
XLR Input and Loop output connectors, and
unbalanced Vampire RCA Input and Loop output
connectors to facilitate connecting multiple JC 1+’s for
bi-amping or looping the audio signal to a subwoofer
equipped with an XLR input.
JC 1+ turn-on options include a variable control to select how much time elapses between the turn-on of multiple
amplifiers. Staggering amplifier turn-on prevents AC line voltage sag and “brownouts” that might occur when turning on
multiple JC 1+’s simultaneously. We added an LED which makes it easy to determine if the JC 1+ is turned on and
ready to play.
Tested like no other
Some of you reading this have heard me compare our product development process to the carpenter’s adage
“Measure twice, cut once.” We’ve taken that to an extreme. Because the JC 1+ is Parasound’s flagship, we delayed
bringing it to market a full year after its development was signed off by Curl and our engineers. We used this time to
test JC 1+ production runs with a rigor that, while unheard of in the audio community, was appropriate for this exquisite
and significant amplifier.
