1. Dirac Live

Setup

The optimal approach to cinema audio tuning is to perform the procedure from inside the theater. The

technician(s) are able to detect any faulty speakers or misdirected audio channels, as well as ensure that

theater curtains and masking are properly opened. Technicians can also take note of any heating or air

conditioning noise, or other extraneous noise that may interfere with audio quality.

1.1. Preparation

Prior to starting the Dirac Live

setup, you must have loaded the Dirac Live

software package onto your

laptop computer. See Appendix A for instructions to install software onto your laptop.

The AP20 should be completely installed into the audio rack as described in the AP20 Installation and

Operating Guide, including all channel assignments, cables and connections to amplifiers, etc. For

detailed information and setup of the AP20 see the AP20 Installation and Operating Guide (TM-H392).

AP20 Password: If the AP20 has a password set, it must be removed before the Dirac

Live

software will connect. Simply entering the password will not work, the password

must be removed. Please see the AP20 Installation and Operating Guide for more

information on setting passwords.

1.2. Projection Room connections and setup preparations

Unlike traditional room EQ that is done in the projection room, the Dirac configuration takes place on the

cinema floor with wireless communications to the AP20. Prior to relocating to the cinema floor, complete

the following:

• Connect the wireless router to the AP20 using RJ45 cable. Connect the power module

supplied with the router.

• Reset the AP20 from the back

panel in order to initialize the connection to the router.

Note: Resetting the AP20 from the front power switch will not initialize the network

connection.

• Check the IP address on the AP20.

To find this address go to Menu > Network. The IP address will be located in the upper left

corner. If the IP address is not listed, check your wireless router connection to fix the

problem.

• On the AP20, set Fader to “7”.

• Next go to Analog Output Levels on the AP20. Select Menu > Formats > Output Channel

Profile > Analog Output Levels.

• In this screen confirm all analog levels are set to 0.0.

1.3. Cinema floor connections and setup

At this point, the technician may physically relocate to the floor of the cinema auditorium that is to be

optimized. Take along the following equipment:
