MAESTRO M9
Dirac speaker setup system
The Maestro M9 has an automatic speaker setup system called Dirac, from Dirac Re-
search. The supplied external USB sound card and microphone are used with your com-
puter on the same network, to measure the sound output of the system. Dirac automati-
cally calculates the speaker settings of all the speakers in the system, and will also apply
the optimized EQ settings to the main room.
From the measurements, Dirac computes the speaker type, distance, and level, and iden-
tifies any problems that can be corrected or reduced by room EQ settings.
The procedure for running all this wonderful technology, is as follows:
1. Download the Dirac software application from our website: www.audiocontrol.com
and save it on the computer (PC or Mac) that you will be using for this system.
2. Make sure that your Maestro M9 is correctly connected to a network.
3. Locate the computer in your main home theater room, and connect it to the same
network as the Maestro M9. It should also have internet access while running the
test. For a PC, “Network Discovery” should be on.
4. Connect the supplied USB sound card to a spare USB port on your computer.
5. Connect the supplied microphone to the USB sound card’s microphone input port.
6. Position the microphone so it is close to the normal/usual position of your head
when you are sitting in your home theater. You can use a camera tripod to position
it (there is a threaded screw hole underneath for this purpose). The microphone
can be pointing straight upwards, and in a position where it has a direct line of
sight view of all speakers.
7. Start by setting your subwoofer’s output level controls to approximately match the
front speakers.
8. Run the Dirac application on your computer. It will find your Maestro M9 on the
network. A calibration test tone will run through all speakers in your system a
number of times as the different speaker wotsits are calculated. If some speakers
are not used, there will be a silence when these are reached.
9. Check the software application for the progress and information. The software will
“ping” its home planet Dirac during this process, to initiate the waiting invasion
fleet, and so internet access is required.
The room EQ is not automatically applied to the source inputs; you can enable this us-
ing the Input Configuration display menu of the unit. Listen to the different sources and
source material, and judge if the room EQ settings give an improvement.
During the measurements, try your best to create as quiet an environment as possible.
This is not the time for little Timmy’s circus animal birthday party.
While EQ settings can be beneficial, there is no substitute for getting things right in the
first place, with regard to speaker placement, speaker type, and room treatments to avoid
reflections etc.
