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 LEFT OUTPUT RIGHT OUTPUT 9130 FUNCTIONAL BLOCK DIAGRAML E F T / M O N O L E F T / M O N O INPUT MONO/STEREO RIGHT INPUTPART NUMBER PARTS LISTDESIGNATOR VALUEm bOIL I/L a’L wc4uTSl ou r”l‘2.5 cl’- u $ cl’ u nXIcl 9 130 CIRCUIT SCHEMATIC DIAGRAM I CIRCUIT SCHEMATIC DIAGRAMYIT I I R208SERVICE POLICY AND LIMITED WARRANTY
