Auricon 2.2+ Manual

 

Electromagnetic Compatibility 

 

NOTE: This equipment has been tested and found to comply with the limits for a Class A digital 
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable 
protection  against  harmful  interference  when  the  equipment  is  operated  in  a  commercial 
environment.  This  equipment  generates,  uses,  and  can  radiate  radio  frequency  energy  and,  if 
not  installed  and  used  in  accordance  with  the  instruction  manual,  may  cause  harmful 
interference to radio communications. Operation of this equipment in a residential area is likely 
to cause harmful interference in which case the user will be required to correct the interference 
at his own expense. 
 
This  equipment  complies  with  the  Class  A  radiated  and  conducted  EMI  requirements  of 
Australian Standard AS3548:1995, including Amendments 1 & 2.

 

 
 
RoHS 
 

The  Auricon  2.2+  card  is  manufactured  for  compliance  with  RoHS  (reduction  of  hazardous 
substances). Certification is available upon request. 
 
 

Notes Regarding Windows Version Differences 
 

Windows XP and Server 2003 are the only current versions of Windows that provide complete 
support  for  “traditional”  WDM  audio  drivers.  Windows  8,  7,  Vista  and  corresponding  server 
versions  provide  limited  support  for  applications  using  the  legacy  audio  APIs,  while  adding  a 
new Core Audio API offering greater functionality. The following limitations apply when using the 
Auricon 2.2+ with various versions of Windows. 
 

  Windows  8,  7,  Vista  and  corresponding  server  versions  virtualise  the  mixer  API  to  each 

application,  providing  only  a  mute  and  volume  control  on  each  input  and  output.  These 
controls  affect  only  the  audio  levels  going  to  and  from  that  application.  A  Windows  XP 
compatibility mode is available in Windows Vista to provide full mixer access to the hardware 
if needed. 

 

  Peak meters for WDM drivers are only available through the mixer API under Windows XP 

and  Server  2003  (and  Windows  Vista  running  in  XP-compatibility  mode).  It  is  possible  to 
access  the  meters  programmatically  under  Windows  2000  (contact  Innes  Corporation  for 
details  and  sample  code). Windows  8,  7,  Vista  and  corresponding  server  versions  provide 
an  IAudioMeterInformation  interface  as  part  of  their  EndpointVolume  API,  but  this  isn’t 
supported on any of the earlier platforms.
