CONNECTING THE JPC
Caution! Make sure all levels are down before connecting!
The JPC is powered by 48V phantom thru the XLR outputs, and automatically turns on when phantom
power is activated. Activating phantom power at the console can cause a loud transient signal spike
which could cause a big “bang” in your sound system or even cause a speaker to blow. Make sure your
system levels are turned off before connecting the JPC and activating phantom power.
The JPC is designed to make connecting all types of audio signals easy. The JPC features a combination of standard stereo
connectors found on PCs and consumer electronic devices. These are connected just like a home stereo system. Cables that
ship with many devices will work with the 3.5mm and RCA inputs. The JPC can even interface electronic musical instruments,
like keyboards and drum machines with 1/4” cables. Or, in a pinch, the JPC can be used as a standard instrument DI.
Finally, the JPC’s ‘thru-put’ feature gives you the option to split the signal and adapt from one connector type to another.
The Inputs and thru-puts
The JPC is outfi tted with a wide array of connectors to make life easy during hectic set-ups. It is important to note that the
3.5mm mini jack is a stereo TRS (tip-ring-sleeve) connector. The ring connects to channel-1 (left), the tip to channel-2 (right)
and the sleeve is a common ground. The RCA jacks follow standard left and right confi guration and also feature parallel
thru-put jacks for convenience. One of the wonderful features of the JPC is that all inputs on the front panel are wired in
parallel and may also be used as thru-puts.
