Connections - Technics SU-7300 Operating Instructions Manual

Do not connect the power cord until all connections
are finished. Also carefully read the operation
instructions for all equipment to be connected.
Connection of speaker systems
This unit has two pairs of speaker terminals, marked
"MAIN" and "REMOTE'', making connection of two
speaker systems possible.
• Impedance of speakers
Use speakers with a voice-coil impedance of 4-16 ohms with
this unit.
• Speaker connection wires
Use medium gauge wire. such as AC power cord, for speaker
connections so as not to decrease the damping factor. •

Connections

For perfect connections, follow the procedure shown in
figure. Note that the left terminals are for the right
channel, and the right terminals are for the left channel:
the orange terminals are
are..
and the black terminals
Strip away about 20 mm (3/4 inch) of the covering of
the speaker wire and twist the core wires together.
Form the core wires into the shape of a fish hook, and
attach to the connection screw.
Turn the connection screw to the right until the core
wires are securely tightened.
NOTE:
Be extremely careful that the terminals or speaker wires do
not "short" each other. Never use the minus speaker
terminal for ground connections.
• Polarity (+) and (-) check
After the connections of the speaker systems have been
completed, confirm that the polarity of the speaker con-
nections to the speaker terminals is correct.
Connection of a record player
• Connections
Connect the record player to the "PHONO'' terminals, being
careful to connect the left and right connection wires cor-
rectly.
If the record player has a ground wire, connect it to the
ground (GND) terminal.
• Cartridge
Use a magnetic cartridge [moving-magnet type (MM),
induced-magnet type (IM), or high-output moving-coil type
(MC)] with an output of 1 mV ~ 10 mV (50 mm/sec).
If a low-output moving-coil type is used, it cannot be
connected directly to the phono terminals; a booster
transformer or head-amplifier must be used.
