想辦個E-MU 1212m代購,問一下大概多少人要

[freesoar]

但如果坐個飛機過來的話，我看大概差不多破萬了…。XD

意思是說越少人買越便宜囉
樓主的女朋友直接帶回即可

音效卡自己坐飛機也還沒那麼貴啦...
不過可能要幾百塊就是

如果是我女朋友帶回來當然不用收這個運費(其實不就是代購費=運費.. :roll: )

不過我們還不知道哪邊可以買到Tax free的網購,幫忙找一下吧XD
因為紐約的稅要 8.x%
很貴的阿..

我自己也從來沒代購過,
如果大家有什麼意見請提出來吧XD

ps.我不太知道那個平衡輸出的線要去哪買阿?是跟phrase22一樣的接頭嗎?
ps2.這張卡到底是有過SRC還是沒過阿?
前面好像看到有人說DSP會過,實際上呢?

那個TRS接頭啊？這種等級的卡當然要用上Cardas的鍍銀/銠接頭才夠發燒啊… [XD]


簡單來說，在使用這張卡的時候，你必需先設定master clock，不然它就不會動。意思就是說它沒有自動選擇sample rate的功能，E-MU是故意這樣做的，原因在下面有詳述。所以，你要的話，就可以啟動SRC；不要的話，就可以bypass SRC。

------------------以下是RMAA forum上的問答整理------------------

Although none of the "FX" (reverbs, chorus etc...) work at 96/192K. The mixer and the audio utilities(trimmers, meters, test tone, sends/returns)which are also DSP Plug Ins do. We are currently studying "FX" at the higher sample rates.

Hi, do the effects run at 24 bit at 41/48khz or are they 16 bit only?

"the card supports DSP effects only in 16\48 mode"

OUCHHHHHHHHHHHHHHHH!!!!!!!!! :mad:

I don’t know why EMU spent some bucks in an awful DSP chip

***Don't know where you got this tidbit of misinformation from. The FX engine in the Digital Audio Systems runs at 32 bits with 67 bit accumulation (double precision with 3 headroom bits) and clocks to whatever sample rate is currently set. So if you set the system at 24/44.1. The system looks like this.

AD (24/44)>>>DSP FX and Mixing(32/44)>>>(truncate)>>>DA (24/44)

***Clarification for Mr. Fixup. If you look a little more carefully you will see that the 2 crystals used in the Digital Audio Systems are.
(24.576MHz) For 48kHz Clock
(22.579MHz) For 44.1kHz Clock

There is also a PLL (Phase Lock Loop) for external word clock.

ICHi,

I looked again and, you were right, there were two small 49.152 and 45.158 crystals. Very sorry for my mistake, but the two big ones (24.576) caught my eyes first.

I would like to sum up about the sampling rate, hopefully this will make things clearer (might make it even more confusing ):

1) The PatchMix, the user interface to EMU cards, always shows the sampling rate locked. This is where most of the confusion from. For example, if you are using RMAA and want to change from 48 to 44.1 or whatever, you must change that in PatchMix first and then change it in RMAA. Other cards, such as Echo Mia lets you set the the sampling rate to be unlocked, so RMAA can change the sampling rate directly. I think this is also the cause for WinAmp's crashing. Note, as ICHi said, such a sampling rate lock in PatchMix does not mean the sampling rate is phisically fixed to 48kHz only, just other programs cannot change SR on the fly and you must do it in PatchMix.

I asked this earlier, why PatchMix does not give an option to set the SR unlocked? Right now the "lock" light is always green.

2) The WDM driver does not currently support sampling rate higher than 48kHz, but ASIO drivers do. This is not a problem for most recording software, but unfortunately RMAA cannot use ASIO drivers directly.

3) FX runs at 48kHz only. Again, this does not mean the DSP is fixed to 48kHz only; utilities such as trimmer do run at any sampling rate.

1.Our ASIO implementation works the way you describe where the App or Patchmix can change each others sample rate at will and they have to be matched. This makes sense for a pro multitracking application where purity and sample rate match is a must, but don't you want your wavs, mp3's or other "just for fun" content to "just play" regardless of sample rate?

If you have some time try this on your MIA, take 2 waves different sample rate and play then simultaneously. What we think will happen is.
1) The first wave will set Mia's sample rate
2) The second one played at the same time will not reset it. It will probably get sample rate converted by WDM. If they both play and sound normal, then guess what? SRC.

So basically our design philosophy was that ASIO is for more pro oriented applications and should always match sample rates. WDM/Wave is more for fun and should just work. If you want to use it without SRC, all you need to do is make sure to match up your source and destination. The Crashing behavior you describe though is not normal, it should not crash when mismatched. It should just work, with WDM SRC. As noted this is logged as a bug and is awaiting verification.

3.No that is incorrect. To be precise.
-The FX algorithms are only available at 44.1/48K
-The DSP and DSP tools like meters, trimmers etc..run at whatever sample rate is currently selected. 44.1/48/96/192.

感謝你的說明
你上面提供的圖,應該是像麥克風的大接頭,直接就是左右聲道.
可是我看到他一組輸出是兩個插座耶..為什麼阿?
?_?

[JCG]

平衡輸出/入，不管是TRS或是XLR都是三根接腳，左右聲道獨立。
直接就是左右聲道，那是"非平衡"器材才是這樣用……ex.耳機接頭

TRS(tip->正，ring->負，sleeve->地)
而XLR的接腳定義則是沒有統一，歐/美廠商的定義就相反，有時候每間廠商都有自己的接腳定義，所以不想燒機器的話最好先查一下使用手冊……

你的意思是說非平衡的TRS一條線傳輸左右聲道
平衡的TRS一條線傳輸一個聲道嗎
抱歉對TRS不熟
搜尋也查不到文章
懇請賜教

[JCG]

大致上是這樣沒錯，當TRS接頭用於傳輸stereo訊號時
tip->左，ring->右，sleeve->地

[freesoar]

如果擴大機只有RCA輸入端
1212M不就只能用非平衡TRS轉RCA再接到擴大機囉

[JCG]

觀念有誤
非平衡的接頭應稱為TS，就是把R 跟S 短路即可，長得像這樣：
