RADIAL / Twin-Iso

A 2-channel isolator that can eliminate hum and buzz noise caused by ground loops.

[直輸入品][Direct Import]

The Radial Twin-Iso is a 2-channel isolator designed for professional-level use in touring, broadcasting, studios, and more. It eliminates hum and buzz noise caused by ground loops in connections between devices such as mixing consoles, amplifier racks, and recorders. It uses high-quality Jensen transformers to maintain a linear, distortion-free signal. Inputs and outputs are wired with pin 2 hot in accordance with the AES standard, but each channel is equipped with a polarity reversal switch to accommodate any usage environment.
