6. Circuit Breaker/Main Power Switch
The main power switch, located on the rear panel of the
S7150, is also a circuit breaker. Putting this switch in
the ON position allows the amplifier to enter the
"standby" and "operate" modes as controlled by the
front panel POWER switch and Manual On/Auto On
switches. Should the amplifier be asked to produce
more power than its design allows for a prolonged
period, or should the S7150 draw an amount of current
from the AC power source that could damage internal
components, the handle of this switch will move to a
center position. Reduce the audio level and wait a
minute for the circuit breaker to reset, then move it to
the OFF, then the ON position. If the handle returns to
the center ("tripped") position, service is required;
contact your JBL Synthesis dealer.
The S7150 was designed to operate reliably under
virtually all conditions. Even momentary short
circuiting of the output (speaker) connections will not
ordinarily damage the output circuitry (although this
will activate internal protective circuitry and cause one
or more of the front-panel blue LED indicators to
extinguish until the circuit resets.)
There are no user-serviceable parts in the S7150; there
are no fuses accessible from outside the unit.
Internal fuses have been incorporated in the S7150 to
protect it from short circuits and other faults, but these
should only be replaced by a qualified technician. In
case of one or more inoperative channels, call your
dealer to make service arrangements.
7. Auto On/ Manual On Switch
Put this switch in the Auto On position if the amplifier
is being used as part of a JBL Synthesis System. When
used in this way, the S7150 will automatically turn on
when the power switch is depressed and the surround
processor is activated. For other installations, or
should individual control of each component be
desired, put this switch in the Manual On position.
The amplifier will then be controlled solely by the front
panel switch.
