Radial – Twin-ISO – 2 Channel Jensen-equipped Isolation Box

Sale!

A Jensen transformer-equipped two-channel line-level isolation box specifically designed for use in concert settings where noise caused by ground loops must be eliminated. This compact device is ideally suited for isolating sub-mixing consoles from main FOH systems and delay towers where separate AC supplies are often employed. Twin-Iso features 100% floating design for true two-channel operation and common ground-lift.

Product Description

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.
