Oehlbach XXL POWERSTATION 909 Bedienungsanleitung Seite 10

Connecting digital devices
Digital devices can react extremely sensitively to disturbing pulses and sometimes even produce high-
frequency interfering signals. Therefore, make sure you connect all digital devices (e.g. DVD/BluRay
player, HDD recorder, PC, etc.) to the digital sockets on the power strip. These sockets are designated
with "DIGITAL FILTER". Devices connected to these sockets are protected by an efficient filter against
all disturbing pulses that arrive via the mains supply. This switching circuit also eliminates interference
caused by the connected devices themselves.
Furthermore, a delay function ensures these sockets are switched with a 2 second delay. This provides
protection against current surges for sensitive hi-fi equipment.
Connecting analogue devices
Connect all analogue devices such as a tuner, record player, tape deck or amplifier to the „analogue"
sockets ("PURE ANALOG"). The XXL Powerstation 909 uses these sockets to provide unfiltered current
for all analogue devices and sufficient reserves for a permanent, stable power supply at all times, even in
the event of high power requirements.
Polarity control
An in-phase connection of all devices will guarantee the best possible, unadulterated sound. This is the
only way to ensure that potential equalisation currents, which have a negative impact on the sound,
are effectively avoided. The POLARITY light indicates that the red sockets are connected in-phase (L). If
the polarity light does not illuminate, switch off the power supply, remove the mains plug from the wall
socket, turn it around around 180° and plug it in again. The polarity LED now illuminates and the phase
designation on the individual sockets correctly designates the phase. To proof the correct in-phase
connection of your HIFI-device, you should use the Oehlbach Phaser (Art.No. 17017). All end devices can
now be connected in-phase accordingly.
Surge protection
If the surge protection function of the XXL Powerstation 909 is triggered as a result of extreme voltage
peaks, the eight sockets (and all of the connected devices) are disconnected from the mains. The
Powerstation can be used again by pressing the RESET button.
Correct operation of the active surge protection function is indicated by the PROTECTED light.
Digital display
The digital display either shows the applied voltage (Volt) or the current energy consumption (>20 Watt).
The two functions can be alternated between by pressing the MODE button. Pressing the DISPLAY button
allows you to switch off the display backlight.
Earth connection
The XXL Powerstation 909 is equipped with a gold-plated earth connection at the rear. Various devices,
such as turntables, etc. can be earthed here.
