New Features:  

SurroundMonitor 10800X series now provides ITU Loudness functionality 

(Software upgrade to version V6.0)

x  

RTW provides a software upgrade with costs for specific hardware versions of the well known SurroundMonitor 10800X series. The upgrade features additional functionality i. e. ITU BS.1770 Loudness measurement functions as well as a new additional quasi DIN scale for digital measurements. New models of the 10800X series are equipped with software version V6.0 as standard. SurroundMonitor 10800 has been the first unit of the successful SurroundMonitor line for years and the first visualisation system with the unique and pioneering Surround Sound Analyzer featuring an intuitive understandable graphical representation of surround signals. 

The main target of the version 6.0 upgrade was provision of some ITU Loudness measurement functionality also for our long lasting owners of 10800X SurroundMonitors. Therefore we added RLB- (K-) filter as described in the actual ITU recommendation. This filter can be used as a Loudness indicator for the individual surround channels as well as for the Dialnorm measurement and the Surround Sound Analyzer. With bargraph loudness measurement the ITU dB LU scale comes into use, which shows a positive and a negative value area. The 0 dB LU point can be adjusted in the range from –25 dB FS to –10 dB FS as well as the integration time for the individual channels, the summed momentary value and the Surround Sound Analyzer (125 ms to 1.5 sec). In addition a summed integrated (shorttem) Loudness measurement can be displayed with integration time of 1 to 12 seconds. A gating function (threshold –30 dB LU to 0 dB LU) can be inserted in the shortterm chain, to eliminate low level modulation components from the calculation. 

With the software version 6.0 another scale for PPM measurements in the digital domain is provided and well known from other RTW equipment: ARD+9. This "Quasi-DIN-Scale" (quasi-analog scale reg. ARD recommendation) shows a display range from –60 to +9 dB. 0 dB is fixed to a digital input level of –9 dB FS. A 0 dB FS 997 Hz sine wave signal will read +9 dB on this scale. Integration time preset is 10 ms. A lot of users like this kind of scale with a headroom above 0 dB because they are used to the behavior from the analog domain. Working with an integration time of 10 ms and the 9 dB headroom, equipment overload is almost impossible. 

Users of a SurroundMonitor 10800X version or 10860X-VID who might be interested in the upgrade should first contact our sales department with the serial number of their unit to verify if it can be upgraded.
