MAINS OPERATION & RESULTING TEMPERATURE
The following tables allow determining power supply and cabling requirements.
The power drawn from the mains network is converted into output power to feed the connected
loudspeaker systems and into heat. The difference between power consumption and dispensed power
is called power dissipation (Pd). The amount of heat resulting from power dissipation might 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 a rack-shelf system/cabinet and the
ventilation efforts necessary.
The column „Pd" lists the leakage power in relation to different operational states. The column „BTU/hr"
lists the dispensed heat amount per hour.

(1) Sine Modulation (1kHz)
(4) 10% Mains Over Voltage
The following factors allow direct proportional calculation of the mains current Imain for different mains
supply voltages: 100V = 2.3; 120V = 1.9; 240V = 0.96
