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.
