Zero-Time Box
For Fast Timing Analysis

The Zero-Time Box is designed to compare the start times of source units with the recording system. It is compatible with every source encoder that outputs a start signal on a BNC connector, and also supports every source controller and decoder that does the same. The Zero-Time Box can also be used as a 5 channel precision measurer of timing intervals.
