; v0 K8 X- } G# n/ n, G至于为什么只有16个通道,我觉得主要是处理能力的限制,我们知道总线里的数字音频是需要时时刻刻保持同步的,而处理器的处理能力则决定着总线的同步。所以关于这个问题,我觉得是因为处理能力的限制。也从另一个角度 ... 1 @. g# T* O( p, Z( v- E+ r8 E

Signals received by one device may be mixed and processed as desired, then passed on to another device, using a separate set of NexLink blocks. NexLink transmissions are unidirectional, however, signals will pass through other devices to reach the destination device.
