3. Verify there is uniformly good sound quality throughout the auditorium. If there are large
differences from one area to another, the EQ and SPL process should be repeated.
3.8. THX RT60 Reverberation Time Test
RT60 (Reverberation Time) is the test name for the measurement of the reverberation within a room. It is
defined as the time required (in seconds) for an average sound pressure level to decrease 60 decibels after
the source stops generating in a room. This and other tests are required for THX certification of a theatre.
Located on the XD10P Input module is a THX Pink Noise Enable jack that is used to perform RT60 and
other tests.
To execute tests, you must have the XD10P software running and connected.
1. Select Outputs tab.
2. Press and hold the Ctrl key on your laptop and select the pink noise box of each channel.
3. Once all boxes are selected connect your test equipment to the THX pink noise trigger jack on the
Input module of the XD10P.
Your test equipment will now activate all channels with pink noise during the test.
For further information refer to your test equipment instructions.
3.9. Built-in RTA Function
The XD10P Setup software features a built-in RTA function. However, the XD10P is not supplied with a
calibrated microphone, so DTS recommends that this built-in RTA only be used for quick checks. Initial
setup and adjustment should use a fully calibrated external RTA device.
Place a microphone in the auditorium and connect to the MIC IN connector on the XD10P. In the Setup
software, click the
Inputs tab and double-click on the Slit EQ. It becomes a real-time analyzer (RTA).
