Status Indicators

These indicators provide information about the actual operational state of the Plasma’s internal power amplifier.

Signal Indicates that an audio signal is present at the input and that it is output.

Limit When lit this indicator signals that the internal power amplifier actually operated at the threshold of clipping. Short-term blinking is not critical, because the amp’s audio limiter keeps distortion under control, so that the sound is unaffected. Input overdrive, which results in sound degradation, is a probable cause for a continuously lit indicator. To prevent this from happening, reduce the input level.

Protection There are two leds to indicate Speaker Protection, or Amplifier Protection. When Speaker is lit the voice coil protection circuit is in operation to prevent over powering the voice coil. Short term blinking indicates high average power of the program signal, sound is not affected. Amplifier indicates the amplifier thermal protection is engaged, this shuts down the amplifier and its sound output. It will reset automatically when its operating temperature is safe. If it occurs check the heatsink location to make sure it in a normal environment. It should not be in the path of very hot air.

Power Switch

AC switch for switching the Plasma’s power ON or OFF. The switch lights after turning the power ON. Make sure that the AC cord is correctly connected if the switch is not lit upon turning the power on. If the AC cord is correctly connected and the AC switch does not light upon power-on, please contact your local dealer.

AC Fuse

During normal operation the AC fuse of the Plasma only blows at the occurrence of a malfunction. Exchanging the fuse is only permissible using a fuse of the same type (current, voltage and release characteristic). In case the fuse blows frequently, please contact your local dealer.

AC Connector

AC connection is established via a PowerCon connector. A 15’ (5m) long AC cord with PowerCon plug is supplied.

CAUTION: THIS APPLIANCE HAS NO USER-SERVICABLE PARTS INSIDE. LEAVE ANY SERVICING AND MAINTENANCE QUALIFIED SERVICE TECHNICIANS ONLY.
