Pop Noise

Although the LA47536 includes an pop noise prevention circuit, pop noise can be reduced even further by using the muting function as well. 

Activate the muting function at the same time as power is applied. Then, after the output DC potential has stabilized, turn off the muting function. 

When turning the amplifier off, first turn on the muting function and then turn off the power supply. These two methods are effective at minimizing pop noise.
