Installation/Assembly >
may be installed in a 19'' standard rack stand through the proper rack mounting brackets provided into the box.
When the unit is installed in a cabinet or in a case, make sure that the ow of air, necessary for proper cooling, is not
obstructed.
Do not block the air vents on side panels.
Avoid installation in places with high temperatures, dust, excessive humidity or water next to the devices, presence of strong
magnetic elds and vibrations.
Close, using blank rack panels, any open space in the rack.
Leave the rear of the rack open. If this is not possible, install a suitable hot air exhaust system.
The high current drain of very high power ampli ers requires an adequate system for AC mains power supply.
It is thus mandatory to use a suitable electrical panel, built in compliance with the applicable country-speci c, technical and
safety regulations, tested by a quali ed technician.

power consumption is limited solely through the internal fuses.
Warning: before any audio connection keep in mind that the regular
procedure is to turn off the ampli er, unplug it from the mains and
set the volume control to the minimum during start up.
Cooling >
Pay particular attention to the ventilation/cooling conditions of the ampli er. An internal system of forced air ow, by a variable
speed fan, allows cooling from the heat generated by power parts; the fan automatically runs faster when the amp is working hard.
Do not block the lateral air vents!
The air ow is directed through the ventilation grills on the side panels of the ampli er; make sure that the ventilation grills are clear of
obstructions and pay particular attention to leave at least 20 mm from the unit's sides and the cabinet side walls.
If the ampli er is installed in a rack cabinet make sure there is enough air clearance: air should easily ow through the ampli er and meet
no resistance.
The unit may be used free-standing, installed in either a rack cabinet or a ight-case box. All models
