Notice!
100 V: 2 x 2500 W means each channel of the amplifier may be loaded with a maximum 2500
W loudspeaker loads.
For example, 50x loudspeakers per channel, each loudspeaker with a power rating of 50
W/100 W.
Mains operation & resulting temperature
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.
Mains operation & resulting temperature tables allow the determination of power supply and
cabling requirements. The tables are 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. Power consumption is direct proportional
for other mains voltages. The following conversion factors are meant for easy conversion: 100
V = 2.3; 120 V = 1.9; 240 V = 0.96.
