• Do not connect this unit or other components to the main power until all connections between components are complete.

• Do not let the bare speaker wires touch each other or do not let them touch any metal part of this unit. This could damage this unit and/

or the speakers.

• All connections must be correct: L (left) to L, R (right) to R, “+” to “+” and “–” to “–”. If the connections are faulty, no sound will be 

heard from the speakers, and if the polarity of the speaker connections is incorrect, the sound will be unnatural and lack bass. Also, 

refer to the owner’s manual for each of your components.

• Use the RCA type pin plug cables for audio components except speakers.

y

• The PHONO jacks are designed to connect a turntable with an MM or high-output MC cartridge. If you have a turntable with a low-

output MC cartridge, use an in-line boosting transformer or an MC-head amplifier when connecting your turntable to the PHONO 

jacks.

• Connect your turntable to the GND terminal to reduce noise in the signal. However, you may hear less noise without the connection to 

the GND terminal for some record players.

CONNECTIONS

Be sure to connect the left channel (L), right channel (R), “+” (red) and “–” (black) properly. 

Before connecting the speakers, make sure that the power of this unit is off.

1

Remove approximately 10 mm (3/8 in) of 

insulation from the end of each speaker 

cable and twist the exposed wires of the 

cable together to prevent short circuits.

2

Unscrew the knob.

3

Insert one bare wire into the hole in the side 

of each terminal.

4

Tighten the knob to secure the wire.

■

Connecting the banana plug

(U.S.A., Canada, Australia and General 

models only)

First, tighten the knob and then insert the banana plug into 

the end of the corresponding terminal.

• One or two speaker sets can be connected to this unit. If you use 

only one speaker set, connect it to either the SPEAKERS A or B 

terminals.

• Use speakers with the specified impedance shown on the rear 

panel of this unit.

■

IMPEDANCE SELECTOR switch

Do not slide the IMPEDANCE SELECTOR switch while the 

power of this unit is turned on, as doing so may damage the unit.

Select the switch position (left or right) according to the 

impedance of the speakers in your system.

• The Canada model cannot use two separate speaker sets (A and 

B) simultaneously when the IMPEDANCE SELECTOR switch 

is slid to the right position.

• If this unit fails to turn on, the IMPEDANCE SELECTOR 

switch may not be fully slid to either position. If this is the case, 

slide the switch all the way to either position when the power 

supply to this unit is completely cut off.

Both AM and FM indoor antennas are included with this unit. In general, these antennas should provide sufficient signal 

strength. Connect each antenna correctly to the designated terminals.

• A properly installed outdoor antenna provides clearer reception than an indoor one. If you experience poor reception quality, an 

outdoor antenna may improve the quality. Consult your nearest authorized YAMAHA dealer or service center about outdoor antennas.

• If you connect an outdoor FM antenna to this unit, do not connect the indoor FM antenna to this unit.

• To minimize interference from automobile ignition, locate the antenna as far from heavy traffic as possible.

• Keep the feeder cable or coaxial cable as short as possible. Do not bundle or roll up excess cable.

• The antenna should be placed at least 2 meters from reinforced concrete walls or metal structures.

Connecting the AM loop antenna

1

Set up the AM loop antenna.

2

Press and hold the tab.

3

Insert the AM loop antenna lead wires into 

the AM ANT terminal.

4

Release the tab.

5

Repeat steps 2 to 4 to insert the AM loop 

antenna lead wires into the GND terminal.

6

Orient the AM loop antenna for the best 

reception.

• The AM loop antenna should be placed away from this unit.

• A properly installed outdoor antenna provides clearer reception 

than an indoor one. If you experience poor reception quality, an 

outdoor antenna may improve the quality. It is recommended 

that you should connect a 5 to 10 m of vinyl-covered wire to the 

AM ANT terminal and extend it outdoors from a window. 

Consult your nearest authorized YAMAHA dealer or service 

center about outdoor antennas.

• The AM loop antenna should always be connected, even if an 

outdoor AM antenna is connected to this unit.

REMOTE jacks

Some YAMAHA models are able to connect directly to the 

REMOTE jack on the rear panel of this unit. If you own these 

products, you may not need to use an infrared emitter. Up to six 

YAMAHA components can be connected as shown below.

your other components to this unit. The AC OUTLET(S) 

supplies power to any connected components whenever 

the power of this unit is turned on. For information on the 

maximum power (total power consumption of 

components), see “SPECIFICATIONS” on page 33.
