INTRODUCTION
In recent years it has become di󰀩cult to nd a hi- receiver that is
equipped with a phono input. With literally millions of albums oating
around the world, a need has emerged to capture these recordings and
transfer them to today’s digital formats.
The Radial J33 provides a solution with a simple device that is ‘plug &
play’ easy-to-use and built to Radial’s professional standards for sound
quality and durability. Equipped with an RIAA preamp and choice of
-10dB consumer line-level and pro mic-level outputs, the J33 is right at
home in the studio, on the stage and in the DJ booth.
FEATURE SET
The Radial J33 is a combination RIAA phono preamp and active DI that
allows you to connect a conventional turntable with magnetic cartridge
to a recording system, hi- or PA system.
The J33 features a pair of stereo inputs for the turntable. A ground
lug is provided to properly ground the turntable to avoid system noise.
This signal then feeds the preamp that boosts the phono signal while
introducing the RIAA equalization curve.
Next to the turntable inputs are a stereo set of RCA connectors that can
connect to the auxiliary or CD inputs on a typical hi- receiver. These
outputs can be used simultaneously with the balanced XLR outputs
described below.
The J33 is also equipped with a low-frequency rumble lter. This gently
rolls o󰀨 the bass to reduce the low frequency rumble and resonant
feedback that can occur when spinning records in high volume
environments such as on stage or in nightclubs.
To connect to professional balanced systems, the Radial J33 is
equipped with a pair of male XLR connectors. The active balanced
drivers convert the signal to a low impedance (600Ω), microphone
level, stereo signal. The J33’s balanced XLR outputs can drive turntable
signals well over 100 meters (328 feet) without appreciable loss or
noise. This makes the J33 ideal for driving turntable signals through a
snake system on stage and through the patchbays and complex wiring
systems in the professional studio.
The Radial J33 may be powered with 48V phantom or with the included
15VDC power supply. The J33 will automatically select the power
source and the two LED on the front panel will illuminate, indicating
power is present.
