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 MONO/STEREO RIGHT INPUT 9130 FUNCTIONAL BLOCK DIAGRAML E F T / M O N O L E F T / M O N O INPUT LEFT OUTPUT RIGHT OUTPUTVALUE PARTS LISTDESIGNATOR PART NUMBERa’L wc4 m bOIL I/Lou r”l uTSl‘2.5 cl’- u $ cl’ u nXIcl 9 130 CIRCUIT SCHEMATIC DIAGRAM I I R208 SCHEMATIC DIAGRAMYIT I CIRCUITSERVICE POLICY AND LIMITED WARRANTY
