Heat Emission
Any power that enters the amplifier through the power cord and does not exit through the
speaker outputs turns into heat, which the amplifier must rid itself of by exhausting it to the
outside. In indoor use this may present a challenge to the buildings air conditioning system.
Use the table below to predict the heat that will be emitted by your amplifier.
Note: the audio test signal for 1/8 and 1/3 power testing is pink noise; the signal for full-
power testing is a 1 kHz sine wave.
