MAINS OPERATION & RESULTING TEMPERATURES
MAINS OPERATION & RESULTING POWER AMP TEMPERATURES
The following tables are useful in determining power supply and cabling requirements.
The power drawn from the mains network is converted into acoustic output to feed the connected
loudspeaker systems plus heat. The difference between drawn power and dispensed power is referred
to as leakage power or dissipation (
remain inside of a rack-shelf and needs to be diverted using appropriate measures. The following table
is meant as auxiliary means for calculating temperatures inside of rack-shelf systems/cabinets and the
ventilation efforts necessary.
The column "Pd" lists the leakage power in relation to different operational states. The column "BTU/
hr" shows the dispensed heat amount per hour.

The following factors allow direct proportional calculation of the power consumption for different mains
supply voltages:
100V = 2.3; 120V = 1.9; 220V = 1.05; 240V = 0.96
