POLARITY CONTROL
An in-phase connection of all devices guarantees the best
possible and undistorted sound. This is the only way to ef-
fectively avoid potential equalization currents, which have
a negative influence on the sound. The POLARITY light si-
gnals that the sockets of the power outlet marked in red are
connected to phase (L). If the polarity light does not illu-
minate, switch off the power outlet, disconnect the mains
unplug the power plug from the wall socket and plug it back in
again, turning it 180°.
The polarity LED will now light up and the phase marking on the
individual sockets of the strip will correctly indicate the phase. To
check the phase correct connection of your HIFI equipment, you
should use the Oehlbach Phaser (art.no. 17017). All end devices
can now be connected connected in phase.
USB SOCKETS
The Powersocket 907 offers two different USB sockets, one
USB-C and one USB-A socket, where multimedia devices (e.g.
MP3 players, smartphones, lap tops ...) can be charged. The USB
sockets only become active when the power strip is switched on
with the POWER switch.
Note: For optimal use of the USB sockets, we recommend a USB-
PD cable (Power Delivery).
OVERLOAD PROTECTION
If the current consumption of the devices is higher than the maxi-
mum load of the Powersocket or there is a defect in a connected
device. The RESET switch is triggered automatically and switches
the complete Powersocket 907 off. This is indicated by the PRO-
TECTED lamp going out.
