FAQS

1) What does PEP actually do to my audio files/waves?

We aren't telling you.  There are plenty of smart folks out there who will be able to fig-
ure it out.

2) Why don't don't we make PEP a plug-in?

It will encourage people to consider what they are monitoring and as of present day 
and for the future in view, the process is so computationally intensive it will not work 
without a dedicated processor for a number of channels commensurate with the AD8's 
intended use.

3) How can I use the AD8 with a laptop?

We designed the AD8 with an AES interface because it is a professional standard and 
open source.  We will not be adding Firewire, USB or Thunderbolt to our boxes. How-
ever, since we've been asked, there are two possible options to use the AD8 with less 
permanent installations.

1. The AD8 is compatible with the 2 ch. optical format that is common on lots of con-
sumer electronic devices, laptops, desktops, etc.  The choice of which 2 channel pairs of 
the AD8 come out of the optical output port is selectable by jumper internally.
