Radial Twin-ISO - 2 Channel Jensen-equipped Isolation Box
The Radial Twin-Iso is a balanced 2-channel, line-level isolator that has been
specifically developed for professional touring systems as a means to eliminate
hum and buzz caused by ground loops when interfacing various equipment such
as two consoles, remote towers and drive racks.
Central to the Twin-Iso is the use of world-renowned Jensen audio transformers.
These assure the very best signal transfer without distortion caused by saturation
or phase shift. All connections are balanced XLR following the AES standard
with pin-1 ground and pin-2 hot. To add versatility, a polarity reverse switch
is provided for each channel to ensure absolute phase is maintained throughout
the audio signal path.
As with all Radial products, the Radial Twin-Iso features a rugged 14-gauge
steel construction for maximum durability and to stand up to the rigors of pro-touring.
The unique book-end design provides a protective zone for the switches while
the full bottom no-slip pad provides plenty of ‘stay-put’ for more active stages.
A unique skeletal design features welded I-beam construction, making it impossible
to torque the internal PC board, reducing the opportunity for cold solder joints
to develop due to outside stress. This unique design also permits up to eight
Twin-Isos to be rack-mounted using the Radial J-Rak in just two 19” rack spaces.
The Radial Twin-Iso is a simple yet extremely effective tool for the professional
audio engineer and system designer.
