Getting Started
Before starting
The MB-450 Signature Monoblocks are shipped in cartons and wrapped in thick plastic. The plastic is not strong enough to
support the unit, and may tear if you try to lift the unit out of the box with it. Also there are protruding switches which could
break if the unit is not properly handled, and in addition to the awkward, unbalanced heavy load
the unit has a cleaning polish on it which makes it slippery and hard to grasp. We have found that
the best way to remove the amplifier from the box is as follows:
1.
With the box on a thick carpeted floor, fold back all the flaps of the top of the carton, leaving all the packing
foam in place. Remove all power cords, Owner’s Manual packages etc. from the carton and save these for
future use. Roll the carton onto one long side on top of the flap.
2.
Roll the box once more onto the open top and, making sure that none of the flaps is trapped under the carton,
lift the carton off the unit.
3.
Lift the top foam away from the upside down unit and carefully cut away the plastic from around the amplifier.
4.
Lift the amplifier up and away from the packaging so that it lands on its four rubber feet. Then lift away the
packaging and set all the packaging in the carton.
5.
When lifting the unit be sure to only lift it from the bottom under the transformers. Be careful not to break any
switches. Be sure to only set the amplifier down on its bottom side on the four rubber feet on a stable surface.
Setting it on any other side may damage protruding components.
If the unit is too heavy or too awkward to lift then do not attempt to do this by yourself, but rather find someone to
help you. Save the carton and all packaging for any future shipment of the amplifiers.
Warning:
This unit is extremely heavy, and weighs over 100 lbs. Unpacking should be done by two or
more people who are capable of lifting a heavy load. Ensure that the amplifier would not fall and injure
someone. Do not attempt to lift the unit yourself.
Check to make sure that no physical damage has occurred during shipping of the unit. There should be no
rattles inside the amplifier chassis. Look through the top cover and check to see that the tubes appear
properly seated in their sockets, and that no tubes are white on top. Contact your VTL dealer immediately
if any physical damage is detected.
Replacing tubes
Turn off the rear rocker switch and remove the power cable before removing any
covers from the amplifier.
