Safety Notes

Before using the product, please read this manual attentively and follow all safety notes. Their purpose is to
keep the user safe and help avoid technical defects and consequential damages caused by incorrect
operation. Make sure teep this manual for future reference.
Caution: The amplifier is a protection class 1 unit. While in operation, make sure the unit's protective
conductor (earth) is connected properly. A missing protective conductor may cause
hazardous voltages to occur on the case and controls!
Caution: Make sure all units of your system are grounded correctly to avoid the risk of an electric
shock!
Caution: Never connect any output of an amplifier to an output, input or ground contact of any other
amplifier. Otherwise you will expose yourself to the risk of an electric shock or technical
defect.
Caution: All connected cables must be laid out in such a way that they cannot be bruised by objects
or be stepped upon! Replace damaged cables at once, don't use them!
Caution: Keep the unit away from dust, moisture, water and other liquids! If despite all care liquid has
got into the unit, immediately pull the mains plug to disconnect the unit safely from mains.
Contact ASID to consult about further measures. Do no longer use the unit under any
circumstances, as fire hazard or injury through an electric shock may result otherwise! For
additional safety the printed circuit boards and components are coated.
Caution: Never open the housing, there are no serviceable parts inside the unit! Leave such works to
a qualified technician.
Caution: Use only suitable cables with a copper cross section of at least 4 mm
loudspeakers. Due to the high output power, fire hazard or injury through an electric shock
may result with an undersized copper cross section! Molten insulations can produce short
circuits, causing equipment or personal damages. The cables must guarantee a long-term
isolation voltage of at least 250 V AC.
Caution: Use mains cables with a sufficient copper cross section of at least 1.5 mm
lengths greater than 20 m, 2.5 mm
unwound completely, otherwise fire hazard or injury through an electric shock may occur!
Caution: According to VDE regulations, the Neutrik PowerCON mains connector must not be hot-
plugged nor pulled out hot! This is especially true under load. The PowerCON is not a plug-
and-socket device designed in accordance with the VDE regulations against burn-up due to
possible spark gaps.
For greater safety and reliability all Hoellstern amplifiers feature an internal mains voltage
monitoring and will cut out almost with no delay in case of a cable interruption. Hence spark
gaps caused by disconnecting the mains supply will be avoided best or put out as quickly
as possible.
Caution: No sensitive signal and data lines, transmitters and receivers must be laid out or built in
close proximity to the loudspeaker and mains cables. Persons with a cardiac pacemaker
must keep a distance of at least 3 m from loudspeaker and mains cables. Otherwise the high
currents (up to 125 A in speaker cables) and the associated magnetic AC fields may produce
malfunctions.
Caution: Before connecting the units to mains voltage, make sure that the respective mains outlet
delivers the correct voltage and has a correct protective earthing conductor. This is
especially critical when working at different venues or with power generators. When
exceeding the permissible maximum input voltage, fire hazard or injury through an electric
shock may result!
are advisable. Cable drums and the like must be
