Whirlwind ISOXL Line Level Isolation Transformer

The ISOXL is an inline line level isolation transformer that drops into an XLR run wherever hum has arrived along the ground rather than the signal. Because it is barrel shaped it goes in at the point of the problem instead of forcing a rack change.

It is housed in a high impact nylon casing, so it survives being trodden on in a cable run, and Whirlwind rates it above the inline isolation transformer it is usually compared against.
