Cascading 01Vs 215
Cascade Delay
Since it takes 01V-A several hundred microseconds to process its digital audio data, the input signals of 01V-B need to be delayed slightly to bring them into phase with the signals from 01V-A. The following illustration shows why phase correction is necessary.

01V-A01V-B
Since signal L has been processed by both 01V-A and 01V-B, it's out of phase with signal R. To bring the signals back in phase, input signal R is delayed by 14 samples on 01V-B.
This kind of phase correction is not unique to the 01V. All digital audio equipment takes a few hundred microseconds to process digital audio data. Use the Delay function (“Delaying Channel Signals” on page 45) on 01V-B to delay all input channels by 14 samples.
Cascading Two or More 01Vs
In this example, the channel delay should be set to 14 samples on 01V-C, 28 samples on 01V-B.
