Comprehensive protection functions ensure safe operation and a long lifetime. The
power amplifier 710 has the following protection functions:

:
For to high levels at the input of the power amplifier 710 the soft clip circuit is ac-
tivated. The activated soft clip circuit will distort the output signal significantly, the
sonic performance is reduced. Please ensure that the input levels are within the
limit of 1.8 Vrms.

For an output current of > 60 A to the loudspeakers the power amplifier 710 is
switched off automatically. This represents a maximal impulse power rating of ca.
3’000 W (48 V @ 0.8Ω)

The temperature of the power transistors is permanently monitored. If the maximal
operating temperature is exceeded despite of active cooling system the power am-
plifier 710 is switched off automatically.

Fuse
The mains connection has a fuse which protects your amplifier against too high
power consumption. Please replace with the same fuse type. The fuse is located
within the mains switch on the rear side of the power amplifier 710.
