Sample Alignment

All digital networks that allow daisy‑chained connectivity need to

compensate for sub‑millisecond latency build‑up between devices when

data is retransmitted. In the majority of cases, there is no audible effect (as

the individual delays are very small), but without compensation, these small

variations in latency can become an issue in certain applications as the

network grows in size.

On power up, each device in the network will calculate a sample alignment

value based on the current sample rate and will apply it as long as the

network is running. The next time the network sample rate is changed or the

system is power cycled, a new value will be calculated and locked in. This

sample alignment value will be referred to as the default value in the text that

follows. Using the default value will offer the simplest method of operation.

However, to guarantee repeatable latency down to the microsecond, the

user has the option of measuring the sample alignment amount for a given

sample rate and then applying that measured value every time the network

is powered up. This is referred to as a stored value in the text that follows. By

using these stored values, the Pro64’s unique software guarantees consistent

delays between each component of the network.

Sample Alignment Status

The sample alignment query, Function 11, can be performed on the Control

Master or any remote unit in the network. The network can use the default

value (created at the time of power‑up) or a stored value.
