ARX IB-2 Audibox ISO De-Balancer Stereo XLR Balanced to Unbalanced RCA
ARX America
Item# ARX-IB-2
A Unique de-balancing unit, the De-Balancer will convert stereo XLR Balanced Low Impedance signals to Unbalanced RCA Low Impedance signals, to allow leads to run balanced from point A to point B and then be de-balanced for connecting to a high impedance/unbalanced input at the B end. This enables you to keep a balanced line all the way up to the input of an unbalanced unit, reducing hum, noise and interference pickup along the way. Transformer Ground isolation provides low-noise operation suitable...
