KK sir

近日發覺speaker 低音有胡胡聲.
初時認定是7294後級有事,因換左部Marantz後級就正常返.
昨天再試7294.都同樣地胡胡聲.但再換電源線(不含水線),馬上正常返!
請問問題何在?
再問...7294是否有很小的noice?因靜止時近Speaker聽到一點點.

Thanks!

Dyna,

May be one of the GND point is missing. Like signal GND or Power GND.

You can take it to me for checking at this SAT & Sun.

KK Sir.

其實唔接水線有無問題?眼見好多日本機都無水線位,
音色唔會因此而有所影響是嗎?
