When you transfer digital audio between two devices their audio clocks must be in phase with one another or phase locked Otherwise you ll hear clicks pops and distortion in the audio or perhaps no audio at all Not phase locked Phase locked wea UU TUUT xe MU UUUUU Figure 3 16 When transferring audio two devices must have phased locked audio clocks to prevent clicks pops or other artifacts There are two ways to achieve phase lock slave one device to the other or slave both devices to a third master clock If you have three or more digital audio devices you need to slave them all to a single master audio clock Master U Master D Slave A Slave 9 Slave Figure 3 17 To maintain phase lock between the PCI 424 system and other digital audio devices connected to it choose a clock master Also remember that audio phase lock can be achieved independently of time code location For example one device can be the time code master while another is the audio clock master But only one device can be the audio clock master If you set things up with this rule in mind you ll have trouble free audio transfers 35 INSTALLING THE PCI 424 HARDWARE 36 DO YOU NEED A SYNCHRONIZER Whether or not you ll need synchronizer depends on your gear and what you will be doing with your PCI 424 system The following pages give you specific information about common sync scenarios At least one of them w

19. If your audio software supports sample accurate sync like Digital Performer and AudioDesk you can do all of this with sample accurate precision The following pages show you how to achieve MMC control where possible Continuous sync to video amp SMPTE time code The PCI 424 system can synchronize directly to video and or SMPTE time code If your audio software supports sample accurate sync like Digital Performer and AudioDesk it can also resolve to video and or time code via the PCI 424 If your software does not support sample accurate sync you need a dedicated synchronizer as illustrated on the following pages INSTALLING THE PCI 424 HARDWARE SAMPLE ACCURATE SYNC Your PCI 424 system provides you with the most advanced accurate synchronization possible with Alesis and Tascam modular digital tape decks and hard disk recorders or any device that supports the sample accurate ADAT and Tascam sync formats Figure 3 18 below shows a few best case scenarios Below is a brief explanation of the benefits you achieve with these setups Sample accurate locating With sample accurate locating when you transfer audio between AudioDesk or any other sample accurate host software and a sample accurate recorder the audio will not drift in time even by as little as one sample This is the tightest possible synchronization between digital audio devices The timing in your audio will not be affected in any way by the process

In all of these cases the front panel clock LEDs flash both sample rates to indicate that the PCI 424 system is slaving to word clock at either twice or half its system clock rate But if the PCI 424 system is running at 96 kHz it cannot slave to word clock running at 44 1 kHz Remember the word clock signal must be one of the following the same as the PCI 424 system clock m twice the PCI 424 system clock a half of the PCI 424 system clock 49 INSTALLING THE PCI 424 HARDWARE SYNC FOR 2408MK3 STAND ALONE OPERATION The 2408mk3 interface goes into stand alone mode whenever it is not under control of the PCI 424 software driver In other words whenever there isn t any 2408mk3 related software running on the computer the 2408mk3 I O will operate as a stand alone format converter For further details about this see chapter 5 2408mk3 Front Panel Operation page 57 Front panel SOURCE setting Front panel CLOCK setting In most cases when the 2408mk3 is performing stand alone format conversion the source of the transfer should serve as the clock source Many of the synchronization scenarios already discussed in this chapter can be used Below is a summary For details on how to make these settings from the front panel see Clock on page 60 and Source on page 62 Required sync connections ADAT Bank A Dig Digital ADAT optical OUT from the source device to IN on the

22. Lower latency versus higher CPU overhead The Samples Per Buffer setting presents you with a trade off between the processing power of your computer and the delay of live audio as it is being patched through your software If you reduce the Samples Per Buffer you reduce patch thru latency but significantly increase the overall processing load on your computer leaving less CPU bandwidth for things like real time effects processing On the other hand if you increase the Samples Per Buffer you reduce the load on your computer freeing up bandwidth for effects mixing and other real time operations If you are at a point in your recording project where you are not currently working with live patched thru material e g not recording vocals or if you have a way of externally processing inputs 2 CueMix DSP immediately patches the live mic signal directly to the main outs or other output completely bypassing the computer dry with no effects processing 1 Live input from mic guitar etc enters the MOTU interface 3 Mic signal is mixed with the main outs and you can control the volume relative to the rest of the mix with the mic s fader in CueMix Console Figure 12 2 This diagram shows the signal flow when using CueMix DSP no latency monitoring Notice that this method does not allow you to process the live input with plug ins in your audio software while it is being monitored You can however a

212. ving to external sync you still need to be concerned with the synchronization of the PCI 424 system s digital audio clock with other devices connected to it digitally if any For example if you have a digital mixer connected to a 2408mk3 interface via an ADAT optical lightpipe cable you need to make sure that their audio clocks are phase locked For details see Syncing ADAT lightpipe devices on page 46 and Make sync connections on page 35 If you don t have any digital audio devices connected digital audio phase lock does not apply to you Resolving DP and the PCI 424 to video and or SMPTE time code If you need to slave Digital Performer and the PCI 424 system to video and or SMPTE time code you can do so with or without a dedicated synchronizer Resolving directly to video and or time code with no synchronizer To resolve your Digital Performer PCI 424 system directly to video and or SMPTE time code with no additional synchronization devices use the setup shown in Syncing to SMPTE time code on page 41 or Syncing to video on page 42 Direct video sync requires 2408mk3 interface SMPTE time code sync can be done with any MOTU PCI audio interface DIGITAL PERFORMER Choose Receive Sync from the Basics menu and choose the Sample accurate option Then make sure that the Slave to External Sync command in the Basic menu is checked Make sure the Clock Source setting in the MOTU PCI Audio C
