TO YOUR RECEIVER CONNECTING THE FM ANTENNA Due to the exceptionally high sensitivity of your receiver, the 48" wire supplied i s sufficient for all but the most difficult locations. The balanced antenna input i s designed to accept a 300 R antenna, indoor or outdoor type. When using the antenna supplied connect one end of the 48" wire to either of the FM antenna terminals. Horizontal placement o f the antenna will yield optimum reception. The antenna may be tacked to the back of the molding behind the equipment or to the shelf you use. At high levels the contour/defeat switch has no effect. CONTOUR DEFEAT SWITCH One of the limitations of human hearing i s its tendency to lose sensitivity to the very low pitched sounds as the program sound level i s reduced. It i s this characteristic (known as the Fletcher-Munson effect) which causes one to play music programs at high listening levels in order to experience the full rich tone available from fine modern recordings. The Contour/Defeat switch compensates for this effect; thereby eliminating high listening levels as a requisite for full enjoyment of reproduced music. - (MAGNETIC PICKUP) Connect both leads from your record player to the CHAN A and CHAN B PHONO MAG input receptacles on the rear of the receiver chassis. PHONO MONO: Selects your record player for monophonic operation. PHONO STEREO: Selects your record player for stereophonic operation. TAPE AMPIAUX: Selects any program source such as tape recorder, ' the output o f your television set, or any other high level equipment connected to the tape amp/aux receptacles on the rear of your receiver. FM MONO: Selects the FM section of your receiver. In this position you can listen to stereophonic broadcasts monophonically while monophonic broadcasts will appear unchanged. FM STEREO: This is the normal listening position for all monophonic or stereophonic FM broadcasts. In this position the stereo indicator light and automatic switching circuit built into your receiver are operative. [. . . ] Plug in the record player and i f hum appears, reverse the record player power plug and connect a single lead from the record player chassis to the ground post on the rear of the receiver chassis. Connect your other devices in this manner. CAUTION: Hum may be also induced by defective connecting cables or by running these cables too close to a strong AC field. 12 MIN MOUNTING SHELF I SERVICE I f this instrument should not perform properly during the first two (2) years after date of purchase, contact the factory for instructions.
