Four types of signs can be used in this manual. The type is closely related to the effect that
may be caused if it is not observed. These signs - from least severe effect to most severe
effect - are:
Notice!
Containing additional information. Usually, not observing a ‘notice’ does not result in damage
to the equipment or personal injuries.
Caution!
The equipment or the property can be damaged, or persons can be lightly injured if the alert
is not observed.
Warning!
The equipment or the property can be seriously damaged, or persons can be severely injured
if the alert is not observed.
Danger!
Not observing the alert can lead to severe injuries or death.
1.2Important safety instructions
Danger!
The lightning symbol inside a triangle notifies the user of high-voltage, uninsulated lines and
contacts inside the devices that could result in fatal electrocution if touched.
Warning!
An exclamation mark inside a triangle refers the user to important operating and service
instructions in the documentation for the equipment.
1.Read these safety notes.
2.Keep these safety notes in a safe place.
3.Heed all warnings.
4.Observe all instructions.

17. This PROTECTION CLASS I device must be connected to a MAINS socket with a safety
ground connection.
Caution!
Use only manufacturer-approved carts, stands, brackets, or tables that you acquired together
with the device. When using carts to move the device, make sure the transported equipment
and the cart itself cannot tip over or cause injury or material damage.
IMPORTANT SERVICE INFORMATION
Caution!
This service information is for use by qualified service personnel only. To avoid the risk of
electric shock, do not perform any maintenance work that is not described in the operating
instructions unless you are qualified to do so. Have all service work and repairs performed by
a trained customer service technician.
1.Repair work on the device must comply with the safety standards specified in EN 60065
(VDE 0860).
2.A mains isolating transformer must be used during any work for which the opened device
is connected to and operated with mains voltage.
3.The device must be free of any voltage before performing any alterations with upgrade
sets, switching the mains voltage, or performing any other modifications.
4.The minimum distance between voltage-carrying parts and metal parts that can be
touched (such as the metal housing) or between mains poles is 3mm, and must be
observed at all times.
5.The minimum distance between voltage-carrying parts and circuit parts that are not
connected to the mains (secondary) is 6mm, and must be observed at all times.
6.Special components that are marked with the safety symbol in the circuit diagram (note)
must only be replaced with original parts.
7.Unauthorized changes to the circuitry are prohibited.
8.The protective measures issued by the relevant trade organizations and applicable at the
place of repair must be observed. This includes the properties and configuration of the
workplace.
9.Observe the guidelines with respect to handling MOS components.
Danger!

1.3Safety precautions
Speaker system damage and protection of human beings
Power amps provide extremely high power output that might be dangerous for human beings
as well as for the connected speaker systems. High output voltages can damage or even
destroy the connected speaker systems, especially, when the amplifier is operated in bridge
mode. Prior to connecting any loudspeakers, make sure to check the speaker system’s
specifications for continuous and peak power handling capacities. Even if amplification has
been reduced through lowering the input level controls on the amplifier’s front panel, it is still
possible to achieve full power output with a sufficiently high input signal.
Danger!
Danger at the loudspeaker/power outputs
Power amplifiers are capable of producing dangerously high voltage output that is present at
the output connectors.
To protect yourself from electric shock, do not touch any blank speaker cables during
operation of the power amp.
Danger!
The terminals marked with a lightning bolt are hazardous live and the external wiring
connected to these terminals requires installation by an instructed person or the use of
ready-made leads of cords.
Danger!
In case of using the amplifier with speakers including a primary tapped transformer, it is
possible that during operation shock hazard voltages may be present at the taps of the
transformer.
Therefore, the taps have to be insulated sufficiently in accordance with applicable safety
regulations.
1.4High frequency interference – FCC/EN55032
IMPORTANT: Do not modify this unit! Changes or modifications not expressly approved by the
manufacturer could void the user’s authority, granted by the FCC, to operate the equipment.

Notice!
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules and EN55032. These limits are designed to
provide reasonable protection against harmful interference when the equipment is operated
in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual,
may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference in which case the user will be required
to correct the interference at his own expense.
