Why not simply use a passive transformer as an interface?
The problem here is both impedance matching a drive capability. A single good transformer is extremely expensive costing
upwards to half the price of the JPC. Because we use an active circuit to drive the signal, we can employ amore cost
effective 1:1 transformer to isolate and active electronics to do the balancing and impedance matching. Ultimately, you get
better sound for your money!
I am not getting any sound?
Check to see if you have the 48V phantom power is turned on at your mixer. The two LEDs on the JPC will illuminate when
phantom power is present.
The sound is distorted?
Try turning down the level from the source or depressing the –10dB pad to reduce the input signal from the source.
Excessive levels can saturate the input transformers, which could cause distortion. Make sure you are supplying the JPC
with a full 48V phantom supply. Some inexpensive mixers will supply lower voltages, which could starve the JPC’s circuit.
Where can I buy a Radial JPC?
Radial products may be ordered from professional audio and video outlets throughout the USA, Canada and around the world
through our network of distributors. If you cannot find one locally, send us an email at info@radialeng.com and we will put you
