1. The first installation of the Marc X an related drivers

* If you want to install a Marc X at the first time, then
  go ahead as follows:

  - Switch of your computer and open the cover.
  - Put one or more (max. 4) Marc X's into free PCI slots.
  - Close the cover and switch on you computer.
  - Start Windows95/98/ME and follow the instructions on the screen.
  - First, the Windows operation system may not find a driver, because it doesn't exists
    at the root directory of you installation disk.
  - Search for the language directory of you choice und click "Ok."
  - Under Windows95b/c it may happens, that you have to choose the correct installation
    directory once again.
  - After you have installed the drivers, the Marc X Sound System is ready for action.

2. Update from older drivers to this driver version

* If you have installed one ore more Marc X(s) and related drivers so go ahead as follows:
  
  - Start Windows and remove all Marc X entries at device managers device list.
    (recommend for users with one card only)
    
    O R

  - Start Windows in SAFE MODE
    (recommend for users with more than one card)

  - If you want to remove an older Marc X driver, then start the Marc X 
    Uninstaller (MARCXUI.EXE), which is located in root directory of your 
    installation disc and (after a successful installation) in windows system directory.

  - Restart your Windows and follow the instructions on screen.

3. What's new ?

Version 1.05:

* New: Solo State Display in Mixer Master Section
* New: Now, the level displays are equipped with a red range at theirs >buttom< end.
  If a red range illuminates, the level of this channel cannot be displayed because
  of inproper clock settings.
* Master Level display now shows the level correctly even if the Master Output Level
  is decreased below 0 dB.
* Active Mute in the channels now also switchs off the level display of the channel
* Level display in mixer and outputs are now more precise
* MME/DirectSound/ASIO
  - Output Volume limited to 0 dB (previously to +6dB which may cause distortions)
* ASIO Direct Monitoring:
  - Analog Output Volume is now controlled digitally by the DSP Mixer instead of
    the DA chip.
* If "Choose Clock Source automatically" (see Settings) is active, now the driver 
  only switchs the clock if necessary, when the mixer window opens.
* If the Clock Source is set manually (see Settings), the driver will not switch the
  clock in any case. If recording or level analysis from S/PDIF or ADAT Input is not
  possible with the current clock, the driver denies it.
* Multiple Card Support: several problems solved
  - Note: with Windows 95/98/ME it is not possible to open 2 mixer windows 
          simultaneously.
* The settings for TOSLINK Output and Wordclock Output are now restored correctly
  when the system restarts or an ASIO application start/ends.

Version 1.04:

* Mixer now controls the input channels correctly
* Several level display issues solved
* ADAT input signals are now switched off, if "no lock" is detected
* Recording channels L/R now in the right order
* Manual clock source selection now works correctly even if the option 
  "Every clock synchronized" is inactive.  
* The analog extender channels (Analog 3-4, Analog 5-6) can now be used even
  if the extender is not installed. This way you have two additional stereo 
  playback devices, whose signals are playback inputs in the Marc X Mixer, and
  the can be a part of a sum routed to any physical output. Recording from
  the analog extender channels without having the extender installed results 
  in an "silence" track/wave.
* ASIO: In some cases some playback or recording devices could not be activated
  in the device setup of the ASIO driver. The ASIO driver detected a configuration
  conflict and requested you to do the configuration again.
  This was caused by a very, very strict error
  handling of the driver, who checked the availability and validity of a
  recording/playback device before activation. This error handling is now
  more relaxed and therefore the following errors are ignored:
  * No lock at a digital input device (ADAT or S/PDIF)
  * Samplerate of an external clock (or digital input signal) does not match 
    with the required clock.
  * Analog Extender should be activated but is not connected
  * Marc X is in use with another sample rate than the required sample rate.
  * Non-ADAT-Mode is active but an ADAT device should be activated

  Anyway, the following errors will cause the ASIO driver to detect a
  configuration conflict again:
  * A requested device is in use by another application
  In this case end all audio applications and setup each single application
  that a single playback/recording device is used by one single application at
  the same time only.

Version 1.03:

* First public release
