Integrated Amp 的phono input

kc2wong

係唔係只可以駁黑膠唱盤？
今日試一試將個DAC駁嚟想試一試work唔work，但爆晒聲兼勁大聲，唔知係唔係有問題，phono input又係唔係一定要駁ground？

!替天行道!

U are crazy. Phono input has different input sensitivity.

thanks，我真係唔曉，係個準買家叫我試一試個phono input work唔work
我果一刻真係驚會燒喇叭

回復 2# !替天行道!

好似話phono個gain超大，而且會針對黑膠波型做整形，吾啱其他source用

phono input 是幾mV, 接受唔到幾百mV架  喇叭會唔會有耐傷

喇叭應該冇野掛，聽咗半個鐘都唔覺有異樣，同埋部amp都應該有maximum output限制咗
反而我驚部amp會唔會有某啲circuit有問題

if it was just instantaneous, should be ok.

take a look at Yamaha as2000 int. amp:
Input sensitivity (minimum)
CD, etc. 150 mV/47 k-ohms
Phono MM 2.5 mV/47 k-ohms
Phono MC 100 μV/50 ohms
Main In 1 V/47 k-ohms

Cambridge Audio DacMagic Plus
Max. output level (unbalanced)         2.1V rms

Audio-Technia AT120 MM cartridge
Output: 5.0mV at 1 kHz, 5 cm/sec
