Calculate your total power needs based on the sum of the power handling capacity and
tapping of all loudspeakers planned in your system. When you use the volume controls,
assume the maximal setting for this calculation.
Make sure that the unit has sufficient air around it for ventilation. For units with a fan, make
sure that the cabinet where the unit is placed in can evict air from the rear. For units without
a fan, leave room on top of the unit for convection. Units with a fan do not need free space
directly above the housing. Take at least 10 cm into account for connectors and wiring. Make
sure that no liquids can spill into or on the unit and that the air intake holes are not
obstructed. Make sure that there is a power outlet of sufficient rating close to the intended
location.
