c. Sequence a noise burst across multiple channels. Declare a first and last channel. The noise

will index from the first channel to the last channel in 3-second increments.

d. Send a NetCmd to the target AP20 and see the returned message displayed in the AP20 Proxy

debug window. Simply type the NetCmd into the Proxy and send it to the AP20.

e. Enable/ Disable and bypass the Dirac Live

playback engine in the target AP20. (This is

useful to demonstrate Dirac Live

room optimization.)

5. Operating the Get State button (in the AP20 Proxy) will report back whether or not Dirac Live

is enabled/ disabled or bypassed. It also will report the name of the filter coefficients that are

currently loaded in the target AP20.

To use the AP20 Proxy as a testing tool you must first operate the Setup ON button to put the

target AP20 into setup mode.

1.4. Starting Dirac Live® Configuration software

1. Start your laptop and run the Dirac AP20 Proxy application (AP20cfg.exe).

2. When the application has started, select the AP20 you will be optimizing from the pulldown list

in the upper left corner.

If the AP20 you want does not appear in the list, select Refresh List.

3. To start a VNC session with the AP20 click on the Remote Session button in the lower left

corner. This optionally allows you to view and control the AP20 front panel menu remotely.

A VNC connection box will appear with the IP Address of the AP20. If the AP20 address does

not appear you may have to use the pulldown and select the correct address. If you don’t know

the address, it may be necessary to find it in the AP20 Network menu.

4. Once you have selected the address, click on Connect.

A VNC authentication box will prompt you to enter a password.

5. In the password box enter a dash (-), then select OK button. If the AP20 has been configured

with a password for the Setup menus, then use that password instead of the dash.

You are now connected directly with the AP20, and the AP20 menu should now be visible on the

laptop screen. You can navigate the menus and control the AP20 remotely.

6. At this time, verify the fader is at “7.0”.

1.5. Set sound levels to establish a baseline

Prior to performing the Dirac Live

EQ procedures, it is necessary to first calibrate the speakers in the

auditorium to establish a baseline.

Equipment needed:

• Calibrated SPL meter

• USB-Pre or equivalent pre-amp

Procedure:

• In the auditorium, confirm that all amplifiers are ON, mute is OFF, and masking and curtains

are opened.

• Set analog output levels on the AP20 to zero (that is, No ‘gain’ nor ‘cut’).
