Digital I/O - Selecting the S/PDIF Output Format

Mia 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.

Mia’s S/PDIF output defaults to the Professional format. If you are recording

from Mia into a consumer DAT deck, the deck may not be able to recognize the

signal until you switch Mia’s output to Consumer.

We have provided a software switch in the Mia driver that allows you to select

which format Mia transmits. In the window that appears you’ll see a pair of check

boxes in an area labeled S/PDIF Out Format: one box is labeled Consumer and

the other Professional. Select the appropriate format for your DAT (if you don’t

know which one to use and are having difficulties, simply try the one that is not

currently checked). Mia never transmits the SCMS bit, regardless of which format

is selected.

Digital I/O - Dither Input

In the top right is a checkbox labeled Dither Input. This checkbox allows you to

enable or disable dithering on the digital inputs. It is off by default. Most of the

time you will want to leave this setting disabled. The only time you will want to

use dithering is when you are receiving a 24 bit signal over the digital inputs, but

you want to record it as a 16 bit wave file. In this case, dithering will improve the

audio quality.

General - Sync 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.

If you have a program that is telling you that our hardware isn't full duplex,

chances are you can fix this by either disabling this switch or enabling Multi-

client audio (see below).
