Often, however, due to long feed lengths, especially in apartment distribution systems, this ground will be of poor quality and could be a source of noise. This interference is usually characterized by a high frequency noise, rather than a hum or a buzz. If such interference is experienced, a separate earth ground connection should be made from the cable outlet nearest the audio/video equipment to a known good earth ground 9130 FUNCTIONAL BLOCK DIAGRAM L E F T / M O N O L E F T / M O N O INPUTMONO/STEREO RIGHT INPUT LEFT OUTPUT RIGHT OUTPUTPARTS LIST DESIGNATORVALUE PART NUMBERa’L wc4 m bOIL I/LuTSl ou r”l‘2.5 cl’- u $ cl’ u nXIcl 9 130 CIRCUIT SCHEMATIC DIAGRAM SCHEMATIC DIAGRAM YITI I R208 I CIRCUITSERVICE POLICY AND LIMITED WARRANTY
