Voltage Setting
Your power amplifier has been set by the factory to the correct voltage for your country where you made
your purchase. The voltage setting should be marked on the Serial Number Badge located on the back
panel of your amplifier. Check to make sure that this complies with your local voltage rating before
plugging in and turning on your amplifier.
Your amplifier is shipped with a 20A power cord which matches the requirements of your country. If you need a
replacement and you are not sure what the appropriate cord should be, consult your authorized VTL dealer or the VTL
factory customer support department.
Power Source for your Amplifier
Your
MB-450 Series III Signature Monoblock
power amplifier is a high-performance, high power amplifier
capable of outputting over 400 watts per monoblock. To assure that you can operate your power amplifier
under the best conditions for the optimal results, you should plug the unit directly into a wall AC outlet,
preferably one separate outlet for each unit. Do not plug your amplifier into a light extension cord or into the back of
another component. This will starve the amplifier of current and significantly impact the performance of your system.
See the chapter on Specifications for the power consumption requirements of your amplifier.
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.
