voltage protection eSSP-800/CT-SSPSurroundSoundProcessorcontainsprotectionfeatures
that prevent the processor from operating at dangerously high or low voltages.
ese features are incorporated to help protect the processor from dangerous
power surges and other power irregularities that could cause extensive damage
to the processor. is circuitry guards against the following irregular supplied
power conditions.
• StartupVoltage:IftheACmainsvoltageisNOTwithinarangeof
approximately –15% to +10% of its nominal value, the SSP does not
turn on. For example, a 120V AC service generally requires the AC
mains voltage to be no lower than 95V and no higher than 135V in
order for the processor to turn on and operate normally.
• Over-voltageConditionduringOperation:IftheACmainsvoltage
surges by roughly 10% or more during operation, the Surround
Sound Processor enters a protection mode and shuts down. e
Standby LED ashes to indicate that the protection mode has been
engaged. An error message also displays on the LCD touch screen.
• Under-voltageConditionduringOperation:IftheACmainsvoltage
sags by 15% or more, the Surround Sound Processor does continue
toplaysincethevoltageirregularitywon’tharmtheprocessor,but
the sound quality may be degraded due to the compromised power
conditions. e Standby LED ashes to indicate an irregular power
condition exists.
In such cases, normal operation can only resume when the following conditions
are met:
• eirregularityinthepowerinputisnolongerpresent.
• eSSPispowercycled,tocleartheprotectionmode.
