=================================INSTALLATION=================================

For new installations see below.  If you are upgrading from a previous 
installation follow the directions in the removal section then install
as below.


===============================NEW INSTALLATIONS==============================

Here are the steps, follow these for both WinNT4 and Win2000

1) If you have the winntv1_29.zip file, use PKZIP or Winzip (or equivalent)
   to extract the release files to a directory.
   These files should be in the destination directory:

        readme.txt 	(this file)
	oemsetup.inf
	StudioNT.inf
	StudioNT.sy_
	StudioMM.dl_
	Studll.dl_
	StudioX.dl_
	Stutray.ex_
	factory.ss_
        user.ss_
	Stupanel.cp_
	NTInstaller.exe
	Win2KInstaller.exe

2) Double click on the NTInstaller.exe icon for an NT system or the 
   Win2KInstaller.exe icon for a Win2000 system to run the installation program.

3) Press the "Install Sonorus STUDI/O Driver" button.

5) The installer will add a shortcut to Stutray.exe to the Startup Group
   for "All Users"  Stutray.exe must be run in order for the STUDI/O board
   to operate correctly.

6) Open the Multimedia control panel and select the "Devices" tab. 
   Click on "Audio Devices" and press the "Add" button.  In the Add dialog
   select "Unlisted or Updated Driver" and enter the directory where you unzipped
   the archive, press OK and then select the Sonorus STUDI/O.  A dialog box will
   inform you that the selected driver is already installed and ask if you want to
   use the current driver or the new one; step 3 installed the new one already,
   so you may select "current."

   This step registers the device driver as a audio device.
   
7) Restart the system.


8) Try your favorite audio editor.


===============================NOTE FOR WIN2000===============================

On startup your system will detect the STUDI/O board and ask for a driver file.
You can tell the system to look in a specific location and then uncheck all of
the location boxes.  When the system fails to find the driver you will be given 
the option to skip installation or to disable the device.  Choose "disable the 
device", the STUDI/O board will continue to work.  If you choose "skip" you will
be presented with the same dialog every time Windows 2000 starts.  We are
working on an INF file that will correct this problem.

====================================REMOVAL===================================

Here are the steps.

1) If you have the winntv1_29.zip file, use PKZIP or Winzip (or equivalent)
   to extract the release files to a directory.
   These files should be in the destination directory:

        readme.txt 	(this file)
	oemsetup.inf
	StudioNT.inf
	StudioNT.sy_
	StudioMM.dl_
	Studll.dl_
	StudioX.dl_
	Stutray.ex_
	factory.ss_
        user.ss_
	Stupanel.cp_
	NTInstaller.exe
	Win2KInstaller.exe

2) Double click on the Installer.exe icon to run the installation program.

3) Press the "Remove Sonorus STUDI/O Driver for NT 4.0" button.

4) Open the Multimedia control panel and select the "Devices" tab. 
   Click on "Audio Devices" and press the "Remove" button.  
   The system will ask you if you want to restart, let it.

5) Restart.

6) If you are installing a new version proceed to "NEW INSTALLATIONS" above.

==============================IN CASE OF DIFFICULTY=============================

If you are getting clicks in the audio, check that the STUDI/O clocks are configured 
properly.  For example, if an external device (e.g. ADAT) is set up using an internal 
clock, the STUDI/O board must be configured to lock to that clock rather than using one 
of its internal clocks.  Note that STUDI/O-based systems are very flexible and many 
different clock and equipment combinations are possible.  Maintaining proper 
synchronization and/or using the on-board sample rate converter are details you must
consider when setting up STUDI/O and external equipment.  If you have access to the
World Wide Web, check out http://sonorus.com for answers to frequent asked questions
(FAQ's), example configurations, and other product info.

If you are getting 'loss of realtime' errors (in our error window), or dropouts, or your
audio editor is mysteriously dropping out of play/record, suspect your video
card.  In your System control panel, under Advanced, click the Graphics... button and
turn graphics acceleration all the way down.  Many video cards out there hog the PCI bus
in order to excel in magazine review benchmarks. Difficulties can arise from using true 
color 24 or 32 bit. Reduce to Hi color 16bit and you note a marked improvement. All audio
programs display well. Our web site hase more pointers and links on how to tame your video.

And if all else fails, read the manual!

Thank you and good night.
