MAKING CONNECTIONS
Using the Radial J33 is easy. Before connecting, start by making
sure all volume levels are set to zero and the audio system is
turned off. This will avoid any loud pops in your sound system
that could cause system damage.
Begin by connecting the turntable outputs to the J33 using the
RCA connectors and securing the ground lead from the turntable
to the ground lug on the J33.
The J33 may be powered in two ways. The fi rst is with 48V
phantom power from a mixing console. The second is with the
J33’s external 15VDC supply. To use 48V phantom power the
J33 must be connected using its XLR connectors to a mixing
console equipped with phantom power. If your mixer is not
equipped with phantom power or if you are connecting to unbal-
anced systems through the J33’s RCA, 1/8” and ¼” connectors
you will need to use the J33’s external 15VDC power supply.
Performance is identical with either power supply and the J33
will automatically select the power source depending on how
you have it set up. As soon as you connect the J33’s external
15VDC power supply or turn on the mixers phantom power, the
J33’s front panel LED indicators will illuminate. When switching
from 48V phantom power to the external DC supply, or back,
please wait 15 seconds to allow the RIAA amplifi er to charge
and stabilize.
Make the connections from the J33 to whichever piece of gear
you would like. The unbalanced -10dB outputs are commonly
known as consumer line-level outputs. These will drive inputs
found on hi-fi equipment and the unbalanced line-level inputs
found on mixing consoles. The balanced XLR outputs on the
J33's rear panel are mic-level so that they will match up with
