J-RAK4 and J-RAK8
The optional J-RAK4 and 8 are high density rackshelfs for Radial DI’s and
splitters. The J-RAK4 is a 19” rack chassis that mounts four Radial devices in
one rack space (1RU). The J-RAK8 mounts eight Radial DI’s in two rack spaces
(2RU). Devices can be mounted with either the input side or output side facing
the front. Ideal way of organizing your DI’s for studio or touring.

WELCOME
Congratulations on your purchase of the Radial Twin-Iso stereo (dual mono)
line-level isolator. The Twin-Iso is a handy device that will allow you to isolate
audio equipment and eliminate troublesome noise caused by ground loops.
The Twin-Iso employs two high-performance Radial Eclipse isolation
transformers to ensure the best signal transfer is enjoyed without artifacts or
distortion. This makes the Twin-Iso a perfect choice where multiple consoles
need to be sub-mixed, when isolating amplifi er distribution racks and for
connecting remote speaker towers. The Twin-Iso can also eliminate ground
loop problems where equipment must be connected to alternate power
sources such as generators.
As with all Radial products, the Twin-Iso is made with 14 gauge steel and
features an internal welded I-beam frame for maximum rigidity. Switches
and jacks are protected by our unique bookend construction, making the
Twin-Iso virtually impossible to damage even in the most abusive touring
environments.
We have purposely written this manual to be short, as most users will likely
be familiar with the Twin-Iso’s applications. We do suggest that you take a
moment to read through this document to familiarize yourself with the features
that have been built in. For more detailed information, please visit the Radial
website. This is also where we post questions and answers that come from
users after the product is released. If you do not fi nd an answer, we invite you
to send us an email at info@radialeng.com and we will do our best to answer
your query in a prompt and professional manner.
INTRODUCTION
The Radial Twin-Iso has been designed to provide electrical isolation
between two line-level devices such as between two mixing consoles, remote
speakers, crossovers and amplifi er racks. Use the Twin-Iso anywhere source
and destination devices may cause system noise because of different ground
potentials (often referred to as ground loops).
So-called ground loops are caused by differing voltage references from various
pieces of equipment that, when connected together, can introduce a 60 cycle
hum in the sound system. Although there are various solutions that can be
engineered to eliminate noise, the simplest and most effective is to isolate the
source and destination with an audio transformer.
The Twin-Iso employs two high-quality Radial Eclipse transformers to do the
task. We engineered the Eclipse line of transformers to handle high input
levels without saturation while transfering the full signal without introducing
phase distortion or group delay. Although the cost is higher, a good quality
transformer will assure the signal remains true to the source, resulting in better
sound.
When you fi rst pick up the Radial Twin-Iso, you will immediately notice the
weight. This ‘hefty’ device employs a welded steel I-beam internal construction
to assure the internal PC will not torque, which of course could develop into
cold solder joints, the single biggest cause of circuit failure.
The Radial Twin-Iso is equipped with two XLR inputs and two XLR outputs. Each
channel is 100% isolated from the other to eliminate cross-talk or interaction,
thus allowing two completely different audio sources to use the Twin-Iso at the
same time. Although the Twin-Iso is designed for +4dB professional line-level
signals, the transformers will actually handle over 20dB without choking.
Each of the Twin-Iso’s outputs feature a 180° polarity reverse switch to ensure
both consoles are ‘in phase’ and pushing the speakers in the same direction.
This allows the Twin-Iso to feed a sub-group or auxiliary input of a console
where polarity reversals are generally not provided. Finally, the Twin-Iso is
equipped with a ground lift switch to further reduce system noise should it be
present.
USING THE TWIN-ISO
As with all Radial products, using the Twin-Iso is simple and straight forward.
Make sure the sound system is turned off and all levels are set to zero before
making audio connections. This will avoid any pops in the sound system that
could cause damage to speakers.
The Twin-Iso is completely passive and does not require a power supply of
any kind. Connect the source device to the Twin-Iso inputs. Connect the Twin-
Iso outputs to the destination device. Turn the system up slowly and listen for
noise. If you encounter noise, simply depress the ground lift switch. That’s all
there is to it.
