Deutsche Welle chose RTW for its compliance needs related to the EBU-R128 loudness mandate. The German broadcaster selected the TouchMonitor line of audiometers.
Deutsche Welle employs a combination of 65 TM3, TM7 and TM9 meters with various configurations and feature sets in its Bonn and Berlin facilities, said RTW. AVS Medientechnik GmbH, based in Berlin, oversaw the procurement and installation.
The broadcaster chose RTW on the recommendation of an ARD working group that had tested loudness meters, according to Hannes Brandt, technical assistant at Deutsche Welle Berlin.
Engineers employ the RTW TM3 units in a combined setup with the RTW PortaMonitor. The TM9 units are used with an installed radar option.
