4.9.4 Fuse Protection

The average mains current can peak temporarily, depending on the load

impedance and type of signal, at values several times higher than the

nominal value allowed by the fuse protection. Continuous monitoring of

the fuse protection status allows the conditions that would trigger the fuse

protection to be predicted. In order to avoid shut-down of the amplifier due

to current overload, the amplitude of the input signals will be limited. The

limitation of the input signal allows the V8 power amplifier to be operated

reliably from a mains power supply of 230 V/15 A (120 V/30 A).

4.10 Main SMPS Protections

4.10.1 Overcurrent Protection

Main SMPS (Switched Mode Power Supply) transformer current of your V8

amplifier is continuously monitored. If over current occurs, the main SMPS

immediately stops working. Should there be an internal failure, this feature

prevents other parts being damaged.

4.10.2 Thermal Protection

The temperature of the main SMPS transformer of your V8 amplifier is

permanently monitored. If the temperature exceeds 85 °C, the main SMPS

is switched off. The amplifier‘s display will indicate a main SMPS error in

this case.

4.11 Fans

The fans mounted in your V8 amplifier operate permanently, but as long as

the temperature remains below 40 °C, they run at their slowest speed and

can hardly be heard. The highest detected temperature from either chan-

nel controls the speed of the fans. Above 40 °C the speed is increased until

it reaches its maximum value.
