Yamaha 3900 bi-amp 問題

當小弟張3900設主聲道為bi-amp時, 前presence喇叭就轉為沒有, 請問各方這是正常嗎? 如這是正常時, 是否代表主聲道bi-amp和前presence喇叭不能同時一齊使用呢? (除pre-out主聲道)
謝

Thanks Peter brother to help my question.

I know this method and I had try again, but is same. I only can turn the bi-amp to on, but after I could not to select the front presence to yes ( at display none is hight light). When I set back the bi-amp to off, then the front presence can select yes. So my 3900 is something wrong or not?

我記得Bi-AMP用上了Surround Back78聲道的喇叭端子,而78聲道的擴大模組跟Presence的擴大是同一組...
所以Bi-AMP,78聲道,前環場,三者只能擇其一.....麻煩Peter大有空幫忙try一下...小弟這邊只有5顆喇叭,無法測試,感恩

A:請進入ZONE 設定將SP 1 改 M

如果接BI-AMP 那Surround Back不能用.但是Presence可以用


請設定SP 1為M

I will back to home try again. I think set the zoning is the main point.
Thanks a lot to Peter & ivory
