Auricon 2.2+ Manual

 

 Configuration

 

 
There  are  four  configuration  settings  for  the  Auricon  2.2+,  these  being  stereo/mono  mode, 
nominal line level, input topology and input coupling. 
 
The 

mode

 may be configured as either stereo or mono. In mono mode the number of input and 

output channels that Windows sees is doubled. 
 
The nominal 

line level

 can be set to +8dBu, +4dBu or 0dBu. In each case the clipping level is 

16dB above the nominal level. 
 
The 

input topology

 can be configured as either a mixer or a selector. With 

mixer

 topology, any 

or  all  of  the  physical  inputs  can  be  mixed  down  into  any  of  the  wave  input  streams,  whereas 
with 

selector

  topology  only  one  physical  input  can  be  selected  for  each  wave  input  stream. 

Note: 

The input topology is always set to 

selector

 under Windows 8, 7, Vista and Server 2012, 

2008-R2 and 2008, as these platforms do not support input mixing. 
 
The 

input coupling

 can be set to either DC or AC (the default is AC). The AC coupling corner 

frequency is approximately 0.1Hz. Note this is applied after the A/D converters, so a differential 
DC offset on the inputs can cause premature clipping. 
 
To change the configuration, right-click on the 

My Computer

 icon on the desktop (or in the Start 

menu in the case of XP, Server 2003, Vista, Server 2008 and 7), select 

Properties

, then click 

on 

Device Manager

. On Windows 8 and Server 2012, open the 

Control Panel

, go to 

System 

and Security

 and then 

System

, and open 

Device Manager

 from the link in the left hand pane. 

Open 

Sound,  video  and  game  controllers

,  then  right-click  on 

Auricon  2.2+

  and  select 

Properties

. Now click on the 

Configuration 

tab and select the desired mode, line level and/or 

topology. Under Windows 2000, XP and Server 2003 it may take a minute or so for Windows to 
reconfigure itself and the screen may flicker during this time. Be patient!
