Yamaha 轉mode "噠"聲係咪正常

The sound is came from the internal relay. It use to control/protect the circuit since different sound mode such as direct stereo, multi-channel or 2 channel, the signal path are not the same. If interest, study basic electronic engineering.

我用665, 轉sound mode 時成日都有"噠"一聲.
唔係speaker出, 係部機身出的聲. 是否正常?

好正常, 轉 mode 果時用 relay 彈開某 d signal path, 因為physically disconnected, isolation 會高, 就係咁簡單

我都估係physically的聲, 多謝咁多位ching解釋. 咁就安心用了.
