USING THE RADIAL JPC
1. Make sure all levels are down before connecting! As the JPC employs standard 48V phantom powering from the mixing console, it automatically turns on when phantom power is activated. Make sure your system levels are turned off as activating phantom will caused a loud pop in the system when activated. The two power-on LEDs on the front panel will illuminate when phantom power is present. 2. Connect the input side using 1/8� or RCA inputs The JPC features standard connectors found on PCs and consumer electronic devices. These are connected just like a home stereo system, output patched to input. In most cases, pre-made cables that came with the audio device will work. 3. Connect the input side using 1/4� TRS input The 1/4� input can be used as a mono input or as a stereo input. When used with a standard, two conductor, �guitar� cable the input will be mono. The mono input signal will be sent to the left XLR output only. When used with a specially made dual mono -to- stereo 1/4� cable, the input signal will be output on the left and right XLR outputs in stereo. The JPC does this by employing a TRS (tip, ring, sleeve) 1/4� jack that can also accept TS (tip, sleeve) 1/4� connectors. This type of cable is essentaly the same as an �insert cable� used to interface outboard equipment with mixing consoles. Stereo connector wired to dual mono connectors 4. Using the Thru-puts The JPC input connectors may also be used as thru-puts to bridge the signal to a second mixer or tape recorder. This means that any unused input can also be used as an output. Clever! 5. Using the XLR Output The JPC XLR outputs follow the AES standard with pin-1 being ground and pin-2 hot. The XLR outputs are generally connected to a snake system or directly into a mixing console. The output of the JPC is mic level and as such, should be connected to the consoles mic pre-amp. The JPC is powered from the consoles 48V phantom. 6. Using the PAD A �10dB pad on the front panel is used when auditioning the source. Some computer audio outputs also serve as headphone outs, which can overload and saturate the JPC�s input transformers. Simply depress the pad if the sound is distorted. Radial Engineering
