CONNECTION

- Turn off power to the whole system before connecting
the speakers to the amplifier.

- The nominal impedance of the SP-D4 is 6 ohms.
Connect them to an amplifier with the load impedance oi
6 ohms speaker.

- The maximum power handling capacity of the SP-D4
is 60watts. Excessive input will result in abnormal noise
and possible damage. 70% of the maximum amplifier
output is normally available when the volume control is
set to its center position.

In cases where the signals described below are applied

to the speakers, even it the signals are below the

maximum allowable input, they may cause an overload

and burn the wiring of the speakers. Be sure to lower

the amplifier volume beforehand.

1) Noise during FM tuning.

2)High level signals containing high frequency
components produced by a tape deck in the fast
forward mode.

3)Click noise produced when turning power of other
components on and off.

4) Click noise produced when connecting or
disconnecting cords with the power on.

5) Click noise produced when the cartridge is replaced
with the power on.

6) Click noise produced when operating amplifier
switches.

7) Continuous high frequency oscillation or high pitch
electronically produced musical instrument sound.

8) Howling when using a microphones.
