Electrical Safety Notice
Electrical voltage from power cables can be hazardous. We recommend that the power cord
used with this unit be connected to a properly grounded (three-prong) AC outlet. There are
also hazardous voltages present inside the unit. To prevent electrical shock, avoid removing
the cover of this amplifier, and under no circumstances remove it while the unit is powered
on.
Warning – Under no circumstances should any attempt be made to
circumvent the ground system to the AC line for any reason
. Using a
ground lifted system can be potentially extremely dangerous, both to persons that might
come in contact with the unit, and to the unit itself, and proper RF shielding cannot be
attained without a secure ground connection.
Damage to the unit that is the result of improper AC connection and grounding will not be covered under the
warranty.
Prior to connecting this amplifier to any audio or video equipment in your system, make sure this
unit’s power (and the rest of the equipment connected to its input and output channels) is turned
off. Adding or removing input or output cables to the amplifier while the system is powered on can
cause damage to the amplifier and possibly also to the rest of the system.
Water and Moisture
The amplifier should be kept away from sources of water or moisture. If liquid enters the unit
it must be immediately returned to your dealer for servicing. Under no circumstances should
you try to power the unit on - the hazardous voltages present in this unit, when combined
with liquid, can result in serious injury upon even the slightest contact.
Location and Ventilation
Warning – To avoid risk of failure due to overheating, do not stack chassis
components
The amplifier emits heat and needs proper ventilation to ensure long operational life.
Ensure that the amplifier is installed in a location that is stable and well ventilated. If the amplifier is
placed in a built-in installation, ensure that there is adequate room for air to flow through the
