1.1 General Precautions

Keep your preamplifi er away from humid places. For example, do not operate the device near air dampeners or in
bathrooms. The relative humidity may be between 10% up to 90% in operation, as long as condensation does not
occur. As with any other electrical device, direct contact with water will not only damage the preamplifi er but will
lead to a hazardous situation that will result in death or serious injury!
Excessive heat or cold will a ect the unit's functionality. Therefore, do not operate the unit near a heat source
such as a radiator and do not expose it to direct sunlight. The permitted operating temperature is 10°C up to 40 °C
(50°F up to 104°F), the storage temperature is between -10°C and 50°C (14°F and 122°F).
Condensation may emerge inside the device, if temperature changes excessively within a short time. In this case,
do not connect the device to the mains as this may result in a short-circuit, leading to malfunctions or damage.
If you, for example, transfer the unit from outside into a heated room in winter, wait at least three hours before
connecting and operating it. Store the device only in a place where the temperature and humidity are constant
as frequent condensation will harm the device. The environment should be free from dust or sources of electric
interference such as fl uorescent tubes or engines.
Do not expose the device to heavy vibrations as this may lead to malfunctions or damages. Install the device in a
level and stable place. Please consider the heavy weight of MBL products!
1.2 Connection to the Outlet
Your preamplifi er features two high-quality toroidal transformers for power supply. Depending on the setting, it
is proposed for the connection to the outlet providing either 230 V/50 Hz or 115 V/50/60 Hz. The device is shipped
with the voltage setting appropriate for the country where it is sold.
If you want to operate the device in a country with a di erent mains voltage, please contact a qualifi ed technician
to have the operating voltage altered accordingly. For safety reasons, this can be achieved only after opening the
enclosure of the device. Further, the fuse must be replaced: A 0.63 amps sb fuse is required for an operating volt-
age of 230 V, a 1.25 amps sb fuse for 115 V.
Note: If you connect your preamplifi er to the outlet with an inadequate voltage setting, it will result in heavy dam-
age. MBL assumes no responsibility for accidents and damages caused by improper settings. Further, changes
made to the voltage setting by a technician will not be covered by the warranty either.
Caution! Whoever opens an electric device without previously disconnecting it from the outlet puts his life at risk
carelessly and irresponsibly. Unplug the unit before opening!
