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).

Sample Rate Lock

These controls allow you to enable or disable the Sample Rate Lock feature, as
well as set the sample rate you want to lock to. While the sample rate is locked, all
sample rate change requests from applications will be ignored and the hardware
will remain at that sample rate no matter what.
This feature is most useful in Multi-client audio mode (see below). Suppose you
have locked the sample rate to 44100. If you are recording a project at 44100 and
another sound tries to play at, say, 22050, the sample rate won't change. Sample
rate locking only applies while your Echo hardware is set to Internal clock. This
setting defaults to unlocked.
