ENGLISH

• Speaker impedance

• When using speaker systems A and B separately, speakers

with an impedance of 4 to 16 Ω/ohms can be connected.

•When biwiring with biwireable speaker system, speakers

with an impedance of 4 to 16 Ω/ohms can be connected.

• Note that when using two sets of speaker systems together

(A + B), use speakers with impedance 8 to 16 Ω/ohms,

using speakers with an impedance other than between 8 to

16 Ω/ohms may cause damages.

Note that this unit is not equipped with a switch for

selecting the speaker system. The A and B speaker output

terminals are connected in parallel.

• The protective circuit may be activated if speakers with

other impedances are connected.

• Be sure to connect the cords between the speaker terminals

and speaker systems with the same polarities (< to <, > to

>). If not, the central sound will be weak and the position of

the different instruments will not be clear, diminishing the

stereo effect.

• When connecting the speakers, be sure that the core wires of

the speaker cords do not stick out from the terminals and

touch other terminals, each other or the rear panel.

• Connecting the speaker cords

q Peel off the sheathing from the end of the cord.

w Twist the core wires.

e Turn the speaker terminal counterclockwise to loosen it.

r Insert the core wires entirely, then turn the terminal

clockwise to tighten it.

Protective Circuit

This set is equipped with a high speed protective circuit.

This circuit protects the internal circuitry from damage due

to large currents flowing when the speaker jacks are not

completely connected or when an output is generated by a

short circuit. This protective circuit’s operation cuts off the

output to the speakers. In such a case, be sure to turn the

power off and check the connections to the speakers. Then

turn the power on again. After muting for several seconds,

the set will operate normally.

NOTE:

Never touch the speaker terminals when the power is on.

Doing so could result in electric shocks.

Connecting the speakers

Connections

NOTE:

• Do not plug in the power supply cord until all connections are

completed.

• Be sure to connect the left and right channels properly.

• Insert the plugs securely. Incomplete connections can result

in noise.

• Note that placing the pin plug cords next to power supply

cords or near power transformers may result in humming or

other noise.

• The PHONO input terminals have an extremely high

sensitivity, so avoid turning up the volume when no pin plug

cords are connected. Doing so may result in induction

humming (booming) from the speakers. When pin plug cords

are not connected, insert the included short-circuit pin plug.

Either tightly twist or terminate

the core wires.
