1 Introduction
The Projector PRO displays the XL2 screen in real-time via USB on the connected Windows or Mac
computer. The software toolbar enables control of the XL2 with the mouse and keyboard. The
background color turns from green to red synchronized with the XL2 limit button color according to the
user-defined limits.
The “XL View” and the “Sound Level Predictor” display extend the XL2 Projector PRO for live sound
monitoring applications.
·
The “XL View” window presents sound levels in large size on the connected computer screen. Users may
select to view one, two or three sound pressure levels. Exceeding levels are presented with a pre-
warning amber or alarming red color.
·
The “Sound Level Predictor” visualizes the level history of the current measurement interval and
indicates the headroom for the actual measurement period or the next few minutes. Green bars confirm
that the present level is well below limits. Red bars are a call to action to reduce the sound level at the
mixing desk. This allows the FOH engineer to optimize dynamic passages of the band for maximum
audience satisfaction while still remaining within the legal limits.
Additionally the Projector PRO software offers the ability to retrieve measurement data from the XL2
without interruption to the measurement process. The entire file system of the XL2 is available while the
XL2 is measuring.
The “XL View” and the “Sound Level Predictor” require that the Remote Measurement Option be installed
on the XL2.
Projector PRO software is a free download for all registered XL2 customers on the support website
