2.9 AP20 Configuration and Setup
This section describes procedures for AP20 audio level adjustment and sound performance verification.
B-Chain alignment will be performed differently depending on whether the (optional) Dirac
Live
®
Theater Setup application or the AP20 1/3 Octave EQ room tuning function is used. In fact, Dirac
Live
®
can be used in conjunction with 1/3 Octave EQ, in a case where Dirac Live
®
is used to tune the
room and then the 1/3 Octave EQ is used afterwards to make some changes to specific frequencies.
2.9.1 Equipment Requirements
Complete checkout and adjustment of the AP20 unit requires the following equipment (not provided by
Datasat Digital Entertainment unless otherwise noted):
a single microphone or multiplexed microphones, connected to an RTA
SPL meter
Real Time Analyzer (RTA)
Laptop computer running VNC for ethernet communication with AP20
(Optional) Datasat AP20 Dirac Live
®
configuration software
(Optional) Wireless router such as the Linksys WRT54GL or similar installed on AP20
Ethernet port (if connecting to laptop in auditorium). NOTE: Wired connection to the
network will work as well, if the physical connection can be made.
2.9.2 Setting and Adjusting Audio Output Levels
The AP20 Audio Processor is designed to accommodate remote operation. For this reason, we highly
recommend the use of a laptop computer for adjusting room EQ. The laptop computer must be connected
to the Ethernet port of the AP20 in order to take advantage of the remote operation feature. You can use
a wireless router (not supplied by Datasat) such as the Linksys WRT54GL or a router with a network
cable for this connection.
