Caution
1. JA-S310 models of intended different areas.
There are four models that have specific voltages to
different areas; these are:
[te |e
Line Voltage
220V 50Hz only
220V 50Hz only
240V 50Hz only
100/120/220/240V,
selectable, 50/60Hz
England, Australia
This amplifier has been pre-set to the line voltage in the
area where it is to be sold. See page 8 to fuse
replacement and to voltage selection.
2. Use this amplifier within 10% of the stated power.
3. Be careful to provide good ventilation while using it,
continuously, with a high output power.
4. Turn off the power.before connecting any components
as the click noise could damage the speakers.
5. Connect the speaker and input terminals, correctly.
Wrong polarity or shorting will result in unstable sound
because of the phase inversion or cause the protective
fuse to be blown. A poor ground connection of the
pin plug, in the input jack, may result in a hum so that
the saturated output will damage the speaker.

Do not operate the switches and controls about 7 or 8
seconds after the power is switched on, for this may
produce an unusual impact noise. Wait until after the
set becomes stable. This impact noise is not the fault
of the machine.
When one pair of speaker terminals, SYSTEM-1 or
SYSTEM-2, are used, speakers with an impedance of 4
ohms to 16 ohms can be used.
When you use the 1 + 2 position of the speaker
selector, the speakers must have an impedance of 8
ohms or higher. If the overall impedance is less than 4
ohms, the set is overstrained. Follow the instructions
given on the rear panel.
The components connected to the AC outlets, should
be of less than 300W in total. AC outlets are provided
only on the ‘’U” type sets.
The TAPE terminals and DIN socket are connected in
parallel, so they cannot be used at the same time. Use
one or the other, but not both.
If you are using a microphone with no components
connected to the TUNER, AUX or TAPE PLAY
terminals, turn down the MIC MIXING control before
operating the SELECT or TAPE MON controls. If you
fail to do this, the sudden rise of mike sound will cause
damage to the speaker.
