is sitting on a shelf, for example – or one is significantly closer to your monitoring position than the
other – we recommend performing an individual calibration for each speaker.
Setting Up the Client Software for Calibration
For the example below, let’s assume that you are calibrating your studio monitors, which are being
fed audio from the Speaker Output portion of Omnia.9’s Monitor Outputs. We will also assume that
you are in a situation where you can use the same calibration settings for both speakers. By default,
the parametric EQ section is set up in the “common” mode, which means changes made to the left
channel will be mirrored in the right channel.
Connect the Client PC and the Calibrated Mic
The first step to calibration is making sure you have a remote connection to your Omnia.9 per the
instructions at the beginning of this manual.
Once connected, plug your calibrated mic into the remote PC, install any necessary software or
drivers, and establish that it is working properly in Windows.
Set Up RTA and Oscilloscope Display Windows
After microphone installation and setup are complete, you will need to make sure you have the RTA
set up in a Display Window. If an RTA is not already visible, select any of the current display
windows (Processing Meters, Undo Meters, etc.) to bring up a Display Settings menu. Set up one of
the windows to monitor the Client Mic input (for example, Display 3, RTA, I/O, Client Mic Input). 1/3
octave resolution will provide more of a “big picture” overview, while the 1/6 octave will identify
more specific peaks and valleys. We suggest an Average setting of 40 and a Target Range of 2.0dB.
You will need to adjust the Target and Range controls for your individual situation once you have
pink noise running through the speakers at a reasonable volume.
We also recommend setting up an Oscilloscope menu in the same manner so that you can watch for
any clipping that may occur should you need to make any significant boots to a particular part of the
audio spectrum during calibration. If you see (or hear) any clipping during the process, turn down
the “Master Gain” control in the Main 1 menu.
Feeding Pink Noise To the Speakers
Next, from the Home menu, select “Client Audio,” “Client Microphone Input,” then “Input Device”
from the Home menu of the Omnia.9 client software on the remote PC. Your calibrated mic should
be available in the device menu. You may need to refresh the list to make it visible.
Return to the Home menu, select “Monitor Outputs,” then “Speaker Output,” then “Main 1.” Turn
down the Speaker Volume to a fairly low level, then enable Pink Noise for the left channel. Turn up
the Speaker Volume enough to bring the level of pink noise well above the noise floor of the room,
and to a level that approximates the volume at which you would normally listen to program material
when adjusting your processing. As you adjust the overall volume, you should see the RTA display
respond.
