The ANF-66 eliminates ground loops from the source Pre-amp outputs and reduces engine noise and DC current through the RCA cables. The ANF-66 uses an audio transformer for ground loop isolation, providing a 1.3dB gain and 0.5dB linearity from 20-20,000Hz. The ANF-66 is directional. The inputs are Male RCA plugs, and the outputs are Female RCA jacks. Insure that the source unit (Stereo, EQ, etc) is connected to the inputs of the ANF-66. Connect the brown wires to ground only if there is no sound out of the amplifier, connect them both to the source chassis case.
