sofa, a bed, thick carpets or blankets), these may block the base plate ventilation
8. Do not install the unit near any heat sources, such as radiators, stoves or other
devices (including amplifiers) that produce heat.
9. Do not render the earthed AC power cables inoperative! The earthing contact
pin serves your safety. If the included cable does not match your power outlet,
please ask an electrician to replace the outdated power outlet.

13. Unplug the unit if there is a lightning storm or when you do not intend to use its
for an extended period of time.
14. Leave all servicing to qualified service personnel. Servicing is required, if:
The unit itself, its power cable or plug have been damaged in any way.
Any liquids have been spilled onto the unit.
Any objects have fallen into the unit.
The unit has been exposed to rain or moisture.
The unit does not operate normally.

TRADITIONAL POWER AMPLIFIER MODE is automatically enabled, whenever
there is no optical DIGM signal present.
Traditional Power Amplifier Mode means:
• Gain is fixed at its maximum, equal to DIGM 66.
• Volume is controlled by reducing the input signal with the help of a preamplifier.
• After turning on the M2 or after changing the INPUT, volume is increased slowly
from DIGM 10 to 66, so the user can still intervene (in case of maloperation), by
turning the unit off, reducing the volume on the preamp, or switching to MUTE or
PAUSE.
• After fading in to DIGM 66, the display will be turned off.
• Attention: Power Amplifier Mode operating at a fixed level output source can
easily lead to damaging noise levels!
• XLR-CI Input without active optical DIGM connection will not be enabled.
Thus the XLR-CI Input is very safe, because protected from unintended Power
Amplifier operation.
