  • Page 8: Unbalanced Input

    CP400 & CP700 COMMERCIAL POWER AMPLIFIER unbalanced Input Unbalanced wiring typically is found on consumer equipment (CD players, DVD players, etc.) and is generally a compromise of noise rejection and cable lengths. A single conductor and an overall shield are most common, as in the standard cables supplied with consumer equipment. Keep unbalanced wire lengths within 10' between equipment, wire the hot lead to the “+”...
