AVM A3.2/A5.2/A5.2T/PA3.2/PA5.2
專用唱頭放大卡
唱頭放大卡可以和您的唱頭個別搭配。在安裝唱頭放大卡之前，首先必須依照閣下唱頭之種類以及不同的特性進行配置。唱頭有MM/MC兩種規格。為了必要的安裝，您需要完整的唱頭數據。與您唱頭所搭配的安裝數據，您可以引用以下的列表調整唱頭放大卡上的諸開關(S1~S5)使得閣下的唱頭能有最佳的表現：
| S1/1+2 | S2/1 | S2/2 | S3/1 | S3/2 | S4/1 | S4/2 | S5/1 | S5/2 | ||
| MM-唱頭之連結 | OFF | OFF | OFF | OFF | OFF | |||||
| 唱頭輸出電平 | < 1 mV | ON | ON | |||||||
| 1 mV – 2,5 mV | OFF | ON | ||||||||
| 2,5 mV – 5 mV | ON | OFF | ||||||||
| > 5 mV | OFF | OFF | ||||||||
| 唱頭容抗匹配 (自唱盤到唱頭放大卡 之訊號線容抗應計算 為：100 pF ) |
< 200 pF | OFF | OFF | |||||||
