SPEAKER FOR AN COMBINATION

SP-VSO have a magnetically-shielded design for placement adjacent

to TVs and monitors without causing color aberrations. However, color

may be affected as a result of how the speaker system is installed.

Therefore, be careful of the following:

1. When placing these speakers near a TV set, turn off the TV's main
power switch or unplug it before installing the speakers.
Wait at least 30 minutes after the system is installed before turning
on the TV's power.

2. If another speaker system has been set up near the TV set. that
system may cause color unevenness in the TVs picture]

3. In spite of the shielded design of these speakers. some types of
TV's may be affected by them. If this happens, move the speakers
at short distance from the TV set.

CONNECTION

- Connect the LEFT speakerterminals of the amplifierto the
LEFTterminals ofthe speaker and RIGHT to RIGHT using
the attached speaker cords as shown in the figure making
sure polarity is correct; (+) to (+) and H to (-). Connect
the black speaker wires to the (-) terminals.

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

. The nominal impedance of the SP-VQO is 8 ohms.

Connect them to an amplifier with the load impedance of

8 ohms speaker.

' The maximum power handling capacity of the SP-VQO
is 110 watts. 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 if 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 compo-
nents 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 disconnect-
ing 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.
