PC-2XR is designed to provide over 90dB of common mode isolation at 60Hz while converting Pro +4dBu signals to consumer -10dBV signals. Transformer isolation allows maximum interconnection flexibility, since both sources and loads may be either balanced or unbalanced. These units allow connection of balanced line level signals to consumer level unbalanced inputs while also providing isolation to eliminate ground loops. Internal Faraday and magnetic shields reject RFI and hum pickup. Output cables should be kept under 10ft (3 meters) to preserve high frequency bandwidth.
