Installation
6. Configuration of the remote input
The U 8A / U 10A will be turned on automatical-
ly if the highlevel inputs are used or if a signal is
applied to the remote input terminal. The Auto
Remote switch (see page 14, item 3; Auto Re-
mote) allows to deactivate the automatic turn-
on feature of the highlevel inputs. The feature
should be deactivated if there are e.g. disturb-
ing noises while switching on / off the active
subwoofer.

Note: If the automatic turn-on function is deac-
tivated it is mandatory to use the remote input
terminal to power up the active subwoofer! The
highlevel signal will be ignored in this case. To
deactivate the automatic turn-on feature you
have to change the position of the Auto Remote
switch to "Off".
