You can also drive the device with 24V(AC).
This is useful in case your mains connection is
broken down and you can bypass this with an
uninteruptible power supply (UPS).
In this case no manual switching is interruped at
the amplifier. As soon the mains connection, the
device is automatically driven by external battery
power, regardless to the position of the ON/OFF-
switch.
Note: The connection cable must be fitted of an in-
line fuse quick blow type F15A.
