請問 Focusrite 的Octopre 如果接駁電腦要買甚麼電腦咭才能做到24bit/96kHz 和8 channel分錄呢 (SPDIF或AES 9 針好些？) (我知道Octopre 的Digital out本身要另外配一張原廠咭的) 還有這張咭要多少錢？
那個9 pin 只是一個分出ADAT和AES 的接頭,等於是你可以友ADAT 8 個輸出或是AES 4 個stereo輸出。可是這樣搞的話你還是要有一錄音卡有ADAT in 或是4個AES in 的卡。ADAT的還比較常見,要那麼多AES in一定都很貴。所以你還是要花不少錢,不可能一台就搞定。 </font><blockquote>引言:</font><hr /> 24-bit/96 kHz ADAT interface card This card provides digital outputs for all eight OctoPre channels, which operate over the full sample frequency range (44.1, 48, 88.2 and 96 kHz) and can be dithered to 16-, 20-, or 24-bit depths depending upon the destination. External word clock synchronisation is possible using the rear panel BNC connector. The card features two ADAT-type lightpipe output connectors. For speeds up to 48KHz both connectors transmit all 8 channels simultaneously. However, ADAT-type connectors are bandwidth limited at sample rates above 48 kHz - each audio channel uses two ADAT digital channels to accommodate the increased quantity of data, hence the need for two ADAT connectors to allow 8 channels of conversion at high speed. 24-bit/96 kHz AES/SPDIF/ADAT interface card This card contains exactly the same ADAT-type digital output facilities as described above, with the addition of AES and SPDIF format outputs via a 9-pin D-type connector on the rear panel. As with the ADAT-type outputs, the full range of sample rates and bit depths are available, and the converter may be synchronised to an external word clock source if required. To access the digital signals from the 9-pin D-type AES/SPDIF output connector the A/D card must be purchased with either an AES or SPDIF D-Type conversion cable, available separately. Either 8 AES or 8 SPDIF outputs can be used simultaneously with 8 ADAT outputs and the OctoPre掇 analogue outputs. </font>[/QUOTE]
9 pins D type would spread into 4 stereo pairs of XLR connectors on the other end......... check the web site ...... http://www.focusrite.com/downloads/userguides.html unless your PC comes with a same D type digital inputs as the outputs from Octopre's card,,, otherwise,you just plug all 4 pairs XLR AES out into the AES in on your audio interface for PC......
