Objects or liquids have penetrated the unit.4. Unit does not operate normally and troubleshooting (last chapter of this manual) does not help.PROTECTIVE CIRCUITSYour new Warwick amplifier is equipped with a series of circuits to prevent it from destruction in case of inadequateoperating conditions:POWER-UP DELAY: When the unit is switched on, the SPEAKER OUT sockets are activated with a slight delay to protectthe loudspeakers.SHORT-CIRCUIT: This feature prevents the output stage transistors from destruction by quickly reducing current in thecase of short-circuit at the power amp outputs.DIRECT CURRENT (DC): This circuit continuously monitors the power amp output for direct current and protects theloudspeakers from overload.HF OSCILLATION: By switching the power amp off, this safety feature prevents from damages that could be caused byfrequencies in excess of 20 kHz (feedback, etc.).EXCESSIVE TEMPERATURES: This circuit protects the output stage transistors from destruction by switching the deviceoff if the temperature-regulated fan cooler prove to be insufficient and temperature of device will be too high.NOTE: You can recognize that one of these circuits has been activated as a result of a fault, when the MUTELED glows continuously even though you have not selected the MUTE mode. In case of short-circuit pleasecheck the speaker cable. The amplifier must then be switched off and on again to get back into playing modeafter having removed short-circuits. In any other situation the amplifier switches automatically back to playingmode as soon as it detects the fault has disappeared (e.g. the amplifier has overheated and cooled down again).9All manuals and user guides at all-guides.com
