Disabling Avid Audio Sever to Prevent Clock Disruptions with Sync X
(Mac Only)
When you quit Pro Tools, the Loop Master changes from Sync X to the primary audio interface in the system, and the HDX or
HD Native Core Audio driver becomes the
Clock Master for the primary audio interface in the system rather than your Sync X. These
changes may disrupt audio outputs of Loop Synced interfaces or those following word clock generated by Sync X (such as MTRX II).
Disruptions are more significant if the Core Audio driver is set to a different sample rate than Pro Tools. Once Pro Tools is relaunched,
the
Loop Master and Clock Master revert to Sync X.
To prevent the
Loop Master and Clock Master from changing (thereby stabilizing the clock) when quitting Pro Tools, disable the Avid
Audio Server.
To disable Avid Audio Server:
1 Locate Avid Audio Server at /Applications/Avid/AvidAudioServer.
2 Rename Avid Audio Server (for example, rename it to “#AvidAudioServer”).
3 Reboot your computer.
Recovery Mode
The Reconfig button on the back of MTRX II should not be used during normal installation. It is intended only as a recovery function
in case something goes wrong during a firmware upgrade (such as unintended power loss or a network error). It lets the MTRX II start
in basic mode so that it can be restored with new firmware without having to be returned to the factory.
The Reconfig button is accessed through a hole in the rear panel using a paper clip, pen, or a similar pointed item. A green LED is visible
through the hole. When the Reconfig button is activated, the LED lights to indicate the first reconfig mode of the MTRX II and the 3
LEDs on the front panel light with a yellow color.
Reconfig pushed while the unit is powering up
Green LED ON
MTRX II enters Firmware Update mode 1. In this mode, only a basic boot firmware is operative in the unit, and new
firmware can be downloaded with DADman software. This mode is used if the firmware in the MTRX II is non-operative for some rea-
son. The IP address settings of the unit are the last setting used in the unit.
Reconfig
Apply a short push while the unit is in reconfig mode and the Green LED is on.
Green LED OFF
MTRX II changes to reconfig mode 2, which is the same as mode 1 but the IP address setting of the unit is set a default
IP address 10.0.7.20 / 255.255.0.0. It can take a minute for the IP address to settle.
The MTRX II will operate with a basic boot Firmware and IP configuration. The MTRX II will not be operational until a proper firm-
ware has been downloaded using DADman software, and it has been restarted. By enabling recovery mode with the default IP address
and network configuration, the unit can be identified on a network using the default setup.
Restore defaults
Apply a long push, approximately 10 seconds, while the unit is in normal operation. This forces a restore defaults of all settings in the
unit.
In order to leave the reconfig mode and enter normal operation, the MTRX II must be power cycled.
To revert to the default behavior, reinstall the Avid HD Driver and reboot your computer.
Note that the IP address referred to is the IP address of the controller/management interface of the unit. This is not the IP address
of the Dante IP audio interface. This IP address cannot be accessed in recovery or restore defaults mode.
