Look
inside a Twin-Iso and you will find the build quality and all
components to be of the highest professional standards. Radial's
proven construction methods and materials ensure highest performance
and years of trouble-free service. The Twin-Iso features Jensen
audio transformers – the best audio transformers in the
industry – to achieve the highest possible signal integrity
and phase coherence while eliminating hum and buzz caused by
ground loops.

Construction
The Twin-Iso is designed to withstand the rigors of high-use
professional environments. Radial's innovative 'book-end' design provides
a protective zone around the switches and connectors that keep these
components safe.
Stress
on circuitboards causes broken and intermittent solder joints, a
common cause of failure in commercial rental and other high-use
environments. Radial's 14-gauge welded I-beam inner chassis and
14-gauge outer shell greatly reduce the possibility of torque stresses
being applied to the PC board.
A full-bottom
no-slip rubber pad works double duty by providing protection from
electrical shock and assuring that the Twin-Iso won’t slip
and slide around.
