iFi 4.4mm to Stereo XLR Interconnect 1mXLR. Excellent. Created to give you maximum quality balanced signal transfer and minimum interference, iFis 4. 4mm to XLR cable employs heavy OFHC continuous cast copper, silver matrix conductors with a total cross section of 16AWG for the best signal transfer. The helix effect. The cable construction is a custom helix minZ design, minimised both in capacitance and inductance. It also has intrinsic shielding provided by the minZ helix construction.
