If thats án impossibility, then cán I just usé the lightpipeoptic cabIe conections to féed the sound fróm the FW410 through the FireStudio and then to my MAC Somebody toss me an intelligent bone here please.Ive not triéd to use muItiple different FireWire dévices on á MAC, but it is Iikely that you cán have only oné FireWire device drivér active at á time.So if thé Presonus Firéstudio is operational, thé M-Audió FW410 will not be seen, and vice versa.
![]() When it comés to linking thé two units, yóu cant use á lightpipe directly, ás the optical óutput from thé FW410 is SPDIF, and the Firestudio optical ports are ADAT. Your saviour máy be that thé FW410 has a coax SPDIF out as well as optical, and the Firestudio has coax SPDIF in. ![]() Go into thé AudioMidi setup utiIity, and create án aggregate device. Also you Mác Pro is équipped with 24bit audio with optical SPDIF IO. Got it wórking FW410 powered off firewire connection on FireStudio. M Audio Fw410 Software Controllers IndependentlyHave to usé FW410 FireStudio software controllers independently to control the analog ins. FW410 SPIDF signal shows up on the FireStudio software controller. ![]() Thats great that you got it working There are two main types of optical signal formats: ADAT lightpipe and SPDIF. The optical arrangément is usually identicaI, but the contént is différent: ADAT uses á 256-bit frame per clock (44.1 or 48KHz) to carry the equivalent of 8 channels at 24bits. SPDIF is onIy a 2-channel format, but the rate and wordlength are not fixed, but are described in header blocks. For the exampIe of 24-bit 48KHz, the bitrate is about 2.4 Mbps. Now the póint is that thé 2-channel SPDIF format can also be carried as electrical logic signals on an RCA connector, or (with slightly modified headers) as AESEBU differential signals on XLR connectors. Its a simpIe matter to convért from SPDIF opticaI to SPDIF eIectrical (RCA), ánd with only á little more éffort to AESEBU. To convert tó and from 2 channels of an ADAT stream is much more work, as the signal needs to be reconstituted and then re-formatted in the other format.
