- Page 4 - Qty 1 Install and Connect the M-1 1. Install the M-1 in the equipment rack using at least two rack screws. If only two screws are used they must be installed in the bottom holes of the rack ears to pre- vent undue stress on the front panel and possible bending.
- Page 5 DHCP addressing of other network connected devices as long as the IP address that is configured for the M-1 does not conflict with the address of any other device on the network. Please consult your friendly IT manager if necessary.
- Page 6 Now that the M-1 has its own TCP/IP identity, we must configure the GUI so that it can talk to the M-1. This is done by adding “devices” to the list of M-1’s that the GUI knows about. To do this, locate and click on the “Devices” button that is located along the right side of the GUI.
- Page 7 First, enter the same pet name that you used when you assigned the IP address to the M-1. The above dialog shows us adding a new device called “AirStu2,” noting that there is already a configured device showing in the Devices dialog box called AirStu1.
- Page 8 After this is done you may click “OK” on the Edit Device box. Then, in the Devices dialog box highlight (single left click) the M-1 device that you just added and click on “Select.” This step tells the GUI specifically which M-1 you want to connect to.
- Page 9 • If Lock mode is off and Local mode is selected when the remote GUI estab- lishes a connection to the M-1, only the front panel controls will have control, but the GUI can still display changes made from the front panel.

XLR connector’s Pin #1. We do not recommend the use of unbalanced connections at the M-1 input. • As far as signal input polarity is concerned, the XLR Pin #2 is “hot” and the M-1 does not invert the phase of the audio. -
Page 16: Rear Panel Connections
Rear Panel Connections All audio input and output, control, Ethernet, and power supply connec- tions are made via various connectors mounted on the M-1’s rear panel. Three XLR connectors are provided for mic input and analog and digital outputs. Two RJ-45 connectors are provided for control and Ethernet connections. -

Page 24: Front Panel Operator Interface
The GUI is designed to operate up to 253 M-1 microphone processors. Since each M-1 unit is associated with its own static TCP/IP address, as is the controlling PC, they collectively would consume all 254 of the usable addresses on a subnet. Remember that address xxx.xxx.xxx.255 is a reserved broadcast address and should never be used... -
Page 25: Architecture Of The Gui
It is also possible to operate the M-1 via a variety of available wireless protocols and hardware. Given the current state of flux of wireless technology we will leave it up to the end user to design and implement the best way to operate the M-1 wirelessly in their particular environment. -

Page 40: Compressor Release Time Operating Hint
While the compressor’s attack time and ratio are typically adjusted to provide peak protection for equipment following the M-1, the setting of the release time control is largely an artistic decision. Please allow us to offer three of the most common caveats of operating a compressor with extremely fast release times. -
Page 41: Expander
This control is adjusted to taste, and ranges from 50 milliseconds to 3 seconds. The GUI Close control on the EXPANDER screen duplicates the function of this control. page 2 – 20 M-1 / June 2007 M-1 / Jan 2009... -

Managing Presets Let’s begin with a simple definition: a preset is a snapshot of all the settings of the M-1. It is desirable in many situations to have a library, or collection, of presets so that we can accom- modate different audio processing needs at different times. As your library of presets grows, preset management (i.e., having... -

.pkg. This allows you to transfer a group of presets from one M-1 to another as a single file, rather than as a set of files. The preset package file is not saved in plain text, so if you load one of them into Note- pad you will not be able to read the settings of the individual presets. -

“Install Preset Package” dialog, which is a standard Windows Open dialog box. The dialog looks for files of type “Preset Packages (*.pkg)” and starts its search within the M-1 install directory. A package thus imported appears in the Presets dialog box as a new package folder under favorites, having the same name as the .pkg file but without the extension. - Page 52 If you try to rename a file to the same name as an already existing file you get an error message as shown. page 2 – 31 M-1 / June 2007...

Page 60: Restricting Access To Controls
Usually when one of the Talent Control skins is being utilized it means that it is desired to restrict access to the M-1’s controls. In order to accomplish this, besides selecting a Talent Control skin it is also necessary to ensure that those skins are the only ones available should a curious user navigate to the Choose Skin function of the GUI and begin to explore. -
Page 61: Changing The M-1'S Proccessing Settings Later
In order to restrict access to the M-1’s processing controls (which could be reached again if talent simply changed back to a standard M-1 GUI skin) it will be necessary to make the non-Talent Control Interface files inaccessible. One way to accomplish this is by deleting all of the files in the Skins folder except for the M1_TalentControl skins. - Page 62 Check the Read Only option and click Apply. Now that configuration is protected even if someone uses the M-1 Device dialog to “delete” a configuration. Simply exit the M-1 GUI and restart it and the original configuration will be restored and available once again to the Devices dialog.
