MAINS OPERATION & RESULTING TEMPERATURE

Mains Operation

The following tables provide a useful aid in determining power supply and cabling requirements. Column “1/8 max. output power into 4 ohms(2)” states the values to be used for normal operation. These results were measured with the power amplifier being operated at maximum output and a Pink Noise signal according to EN60065 applied at the input, which approximately represents the strain of an audio signal driving the power amp at maximum modulation.

Temperatures inside of the power amplifier

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 (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” shows the dispensed heat amount per hour.
