16. Preamp Name display: user defined name for this preamp. The names is limited to standard
alpha-numeric characters and has a maximum length of 11 characters.
17. Indicator display: Illuminates green while communication is good. Illuminates red if
communication times out with the preamp. The web controller will attempt to re-establish
communication with the preamp if it times out.
To connect your browser to the m108 simply type the preamp's IP address in the address bar. (refer to
"ethernet setup" above for IP address information)
If there are multiple preamplifiers in your system you can open a new browser tab for each preamplifier.
8.2 MIDI Control
The m108 can be controlled directly from AVID ProTools® HD, via the MIDI combination DB9 connectors
on the m108 and the AVID I/O. Using the m108 with ProTools® requires some setup in ProTools® and the
host computer’s MIDI configuration (MSS for windows, AMS for MAC). When connected to a ProTools®
system, the m108 is designed to emulate the AVID®Pre. This means that configuring the m108in the “I/O”
and “Peripherals” settings in ProTools®, it is necessary to choose the exact same settings as the AVID®Pre.
For a detailed discussion of Pro Tools® Pre configuration, please read the AVID PRE user guide which can
be found here: http://www.avid.com/~/media/avid/files/support-pdf/resources-
pdf/pre_guide_v90_70448.pdf (file subject to relocation, google will help). Chapter 3 includes operating
system as well as Pro Tools® configuration information which will allow Pro Tools® to recognize the m108
as a AVID Pre.
A set of MIDI to DB9 breakout cables will be needed to connect MIDI in and MIDI out from the host com-
puter MIDI interface. For systems with multiple m108s MIDI jumper cables will be needed to link the
m108s together. See the wiring diagrams at the end of this manual. These cables can also be purchased
through your Grace Design dealer.

Since the AVID Pre and the m108 have differing features, there will be some m108 functions that are not
available when in MIDI mode. As well, there are AVID Pre functions that do not exist on the m108.
Following is a summary of these limitations:
Gain Control
The m108 has a gain range of -6 to 69dB in 1dB steps. When in MIDI control mode the m108 switches to
a gain range of -6 to 63db in 3db steps. If the m108 has channels set to gain values that are not available
in MIDI control mode and the m108 receives MIDI activity, it will change these channels to the next low-
est gain setting that is available in MIDI control mode. If the MIDI control mode times out and the m108
