ventilation openings. Allow at least 12 inches clearance on the top and around the sides of the chassis of the amplifier.
The warranty does not cover units that are damaged due to overheating from incorrect installation.
Tiptoes or other isolation accessories may prove useful in reducing mechanical vibrations or other external vibrations
that might affect sonic performance, and we have found that such accessories can offer distinct sonic improvements
when used correctly. In all cases you should be sure to install this amplifier in a location that is stable.
The warranty does not cover damage due to the unit falling.
Do not place the amplifier next to heat sources such as radiators, stoves or other appliances.
Do not place the amplifier where small children might be able to tamper with the equipment. If it is not possible to
place the amplifier out of the reach of small children it is recommended that you remove power cables when the
equipment is not in use.
Servicing
Do not attempt to service the amplifier beyond the procedures described in this manual. For all
other service and questions, please contact your authorized VTL dealer or the factory.
Operational Warnings
It is critical for proper sonic performance of this component that it be properly configured for
the mode of operation while playing. If a balanced signal is applied to the inputs the amplifier
must be configured for balanced operation, and vice-versa.
Always make all connections before powering the amplifier on. Ensure that interconnect
cables are firmly seated and that there is no visible damage to the cables.
Connecting or disconnecting the amplifier while powered on can damage the output stage. Such
damage will not be covered under the warranty.
Warning:
The MB-450 Series III is a fully balanced design with a balanced output. Care
should be taken so that neither output is ever grounded.
Warning:
Do not connect a sub-woofer to the output of the amplifier unless you are sure
that the subwoofer input is fully balanced and that neither phase can become
grounded.
Please consult your authorized VTL dealer or the VTL factory customer support department if you have any questions
on the fully balanced connection of the amplifier.
