Synchronize wave devices

This is mainly for developers who are using tools like Visual Basic or Delphi and

want the inputs and outputs to be totally independent. Unless you have a good

reason to turn it off, you should leave this switch on. Also, if you are running

multiple applications on one card and you can’t get it to work, try un-checking this

box.

Digital I/O

This lets you set the format of your S/PDIF outputs.

Your Echo card can transmit digital information in either of two formats:

“professional” or “consumer.” The primary difference between the two is in the

implementation of the SCMS copy protection bit, which, in the Consumer format,

prevents the user from making digital copies of a digital copy.

The S/PDIF output defaults to the Professional format. If you are recording from

your Echo hardware into a consumer DAT deck, CD recorder, or Mini Disc

recorder, the device may not be able to recognize the signal until you switch the

output to Consumer.

Select the appropriate format for your DAT, CD recorder, or Mini Disc recorder (if

you don’t know which one to use and are having difficulties, simply try the one

that is not currently checked).

Note:

No Echo hardware transmits the SCMS bit, regardless of which

format is selected.
