4. OPERATION
4.5 Main SMPS protections
4.5.1 Overcurrent protection
Main SMPS (Switched Mode Power Supply) transformer current of your LINUS10 amplifier is continuously monitored.
If overcurrent occurs, the main SMPS immediately stops working. Should there be an internal failure, this feature prevents
other parts being damaged.
4.5.2 Overload protection
In case of extremely high output levels with heavily clipped output signals and low loudspeaker impedances < 3 Ohm,
this additional protection will re duce the amplifier stage output current very quickly. If activated, this indicates that
the amplifier is running close to it's absolute maximum power capacity. In normal operation (no clipping or only slight
clipping) this protection should never be activated. If active, this protection is indicated by a white LED behind the dust
cover (on the top left side of the dust cover).
NOTE: Please reduce the input level if you see this LED flashing.
4.5.3 Thermal protection
The temperature of the main SMPS transformer of your LINUS10 ampli fier is permanently monitored. If the temperature
exceeds 85°C/185°, the main SMPS is switched off. The amplifier's display will indicate a main SMPS error in this case.
4.6 Fans
The fans mounted in your LINUS10 amplifier operate permanently, but as long as the temperature remains below
40°C/104°F, they run at their slowest speed and can hardly be heard. The highest detected temperature from either channel
controls the speed of the fans. Above 40°C/104°F the speed is increased until it reaches its maximum value.
