Referehce: 65oFET R by Quadraflex AM / FM StereoReceiver Cong ratu lations ! Your new Reference: by Quadraflex 650FETR is the first stereo receiver to utilize special MOSFET power transistors. These advanced devices reduce high frequency distortion to a fraction of that found in conventional receivers. The absence of distortion at frequencies far beyond the range of hearing assures a purity and clarity of sound that is unprecedented. lntroduction Your new Reference:650FETR has been engineered by Quadraflex to provide years of satisfaction. Proper installation, connection and use of its controls are essential for you to take full advantage of its quality and versatility. This manual is organized for your rapid understanding and enjoyment of your Reference: 650FETR. U n packi ng Carefully remove the Reference:650FETR from its carton. Avoid lifting by the AM antenna mounted on the rear. lt cannot support the weight of the receiver. Save all styrofoam packing; it is essential for secure shipping or moving. There is also a small plastic bag containing a light colored wire. This is the FM antenna so don't throw it away. Look on the rear panel of the 650FETR and locate the serial number. Make sure it is marked on your dated purchase receipt. Save this to validate ownership if your Reference:650FETR ever requires service or is stolen. Placement Place your 650FETR on a sturdy table or shelf, leaving enough space to get at its rear panel connections. You must allow several inches for ventilation and avoid putting it on a rug that might impede air circulating into vent openings on the bottom. Keep the 650FETR away from direct sunlight or other sources of excessive heat. Avoid placing it where it might be exposed to rain or moisture. Before making connections. make sure the 65OFE1R is not yet plugged into the wall. This must wait until all connections are made.

Speaker Connections For the best performance we recommend the use of 1B-gauge "lamp" or "zip" cord. Use of thinner wire will impair power transfer to your speakers. Prepare the speaker wire by cutting two approximately equal lengths and running them where they are safe. At each end separate the paired wire for several inches and strip aboul1/t to % inch of insulation at each end. You can do this by slightly cutting the insulation with a knife or razor, being careful not to cut into the wire strands. Then pull off the unwanted insulation. Twist the exposed strands tightly. You should now examine the wire closely. One side of the pair will either have a ridge on its insulation or a different color wire if the insulation is transparent. When you connect your speakers make sure the wire with the ridge or copper color goes to the positive terminal, usually marked +, 8 ohm, or positive, and the other wire to the negative terminal usually marked - , 0, or negative. Make sure each speaker is wired the same way. Locate the bottom row of speaker terminals marked A. The two left-hand terminals are for the wires going to the speaker on yout' right (as your face the front of the receiver). The two right-hand terminals are for the speaker on your left (facing the receiver). Connect each, remembering to insert the coded wire into the + terminal marked in red on your 650FETR. To make connection, push on the tab below each terminal, insert the wire into the exposed hole and release the tab. At this point inspect your connections to make sure that there are no strands touching between wires or terminals either at your receiver or speakers. You may connect a second pair of speakers to the upper row of terminals marked B. Use the same procedures. Your Reference:650FETR can safely operate two pair of speakers whose impedance is 8 ohms or higher. lf either pair of speakers is rated below 8 ohms, then only one pair may be operated at a time to avoid overloading the amplifier section. Caution: Never make any speaker connections that join two red speaker terminals on your 650FETR. This willcause serious damage and will not increase power output. lf you connect only one speaker, use either the L or R terminal, but not both. Turntable Connection Make certain your turntable is equipped with a high quality magnetic cartridge. The two audio cables attached to the turntable will have different color plugs to identify L and R channels. Push the right channel plug firmly into the bottom jack (R) on the 650FETR marked Phono 7 and the left channel plug into the top jack (L). Make sure they are pressed as far as they can go. Slight twisting of the plug as it is being inserted may be required if it is very tight. Many turntables also have a separate wire that is for ground- ing it to the receiver. Loosen the metal nut marked Gnd on the 650FETR, slip the end of the ground wire under it, and retighten the nut. A second turntable can be connected to the Phono 2 jacks and ground using the same procedure. The power cord from the turntable can be plugged directly into the wall or into the outlet at the rear of the 650FETR marked Un- switched. This outlet is "live" whenever the 650FETR is plugged into the wall.
