The
Radial JPC is a stereo direct box that has been specifically designed
for use with computer sound cards and other consumer electronic
products to allow these to be connected to a professional sound
system. It is unique in that it combines the advantages of transformer-isolated
inputs with an active drive circuit, giving you the ‘best
of both worlds’ in a compact and extremely flexible package.
Transformer
coupled inputs have the unique advantage of isolating the ‘source’
from the ‘destination’. This proven approach eliminates
60-cycle hum and buzz caused by so-called ground loops when two
pieces of electrically powered devices are connected together. Because
the active circuit does all of the impedance conversion and balancing,
a dedicated 1:1 transformer can be used. This results in a hybrid
design that is at once great sounding, compact and more affordable.
As
with all great designs, simplicity is a fundamental trait and the
Radial JPC certainly fits the bill. A choice of stereo ¼”,
1/8” and RCA input AND thru-put connectors make interfacing
a snap with all types of equipment. A single switch inserts a –10dB
pad, two power LEDs confirm 48V phantom is turned on, and a pair
of XLR output connectors round out the feature set.
Of
course like all Radial products, the JPC is built to handle any
environment. The book-cover wrap-around sleeve design protects switches
and connectors from damage while the 14 gauge steel I-beam construction
eliminates stress that could torque the PC board and cause solder
joint failure. A full-bottom no-slip pad provides electrical insulation
and mechanical isolation with plenty of ‘stay-put’ for
use on hectic stages. And with its baked enamel finish, the Radial
JPC will continue looking great for years!
