关于音频CD->不能在PC上导入:
通常的CD音乐盘使用的文件格式为CDA格式,Pro Tools导入CD音频是通过QuickTime转换导入的,而PC上的QuickTime不像在Mac机上,PC上没有这种转换功能,所以不能导入CD上的音频.即便用Import Movie也是不可用的.
数字输出:楼上那位说的Aux本来可以用,可惜的是002上根本没有4路Spdif数字输出,所以不可能分轨输出4路Spdif数字.
关于同步,这是PT,也是所有系统中最复杂的部分,你应该从手册中找答案,但有一点是,同步与PT系统中的同步相关选项和系统的延迟量都是有关系的.
下面是一部分设置最小延迟的方法,更多可在手册中查阅:
设置最小同步延迟:
Lock-up time delay is the amount of time your system's devices need to achieve synchronization "lock." This amount varies for each device. Pro Tools lock up delay is set by entering a value for Minimum Sync Delay in the Synchronization window of the Peripherals dialog. The lowest value available is 15 frames. Find the shortest possible lock-up time that your equipment can operate at consistently, and set this as the Minimum Sync Delay. On systems utilizing Digidesign MachineControl, enabling the Use Serial Time Code setting will make machines lock up much faster. (Serial time code requires both the SYNC I/O and external devices to be locked to house video reference.)
To set a Minimum Sync Delay:
Choose Setups > Peripherals, and display the Synchronization pane.
Enter a number of frames in the Minimum Sync Delay field.
Click OK to close the Peripherals dialog box.
配置外部MMC设备的最小延迟:
When controlling a house-synced device from Pro Tools through MMC, the device will first lock to the MMC location and then align the color framing. Within house sync code are 4 frames for ensuring color frame lock. If the minimum synchronization setup time is less than the time required to achieve both location and color frame lock, playback will begin before the device has aligned the color frames. In this scenario, you should set the Minimum Sync Delay to be more than the time required for color frame lock. This is not a problem with the SYNC I/O, which will drop out of lock until the color frame is locked.
实际上,如果没有Sync I/O同步器,能调整的同步选项少的可怜,PT同步的高级功能,都是通过其Sync I/O实现的.
手册附录中专门有一张讲述每一个动作会对PT有多少个ms的延迟影响.
