The input tests were conducted at 1 kHz sign wave input signal with 8 ohm loads connected condition, and 
then replaced the input signal to pink noise for heating and fault condition tests. 
The values followed #)  in table above are measured “A” or “W” value, when replaced the input signal 
from 1 kHz sign wave to pink noise.

most of the top cover. This indicates emission of heat from internal parts and the opening area is 
 
therefore not likely to be touched during normal use.
