Beijing TV (BTV) has installed six PAM2 Mk2 Audio Monitoring Units from TSL Professional Products (PPL) in its production facilities, bringing it into line with current loudness requirements. The PAM2 Mk2 units give BTV advanced loudness and confidence monitoring capabilities that include Dolby E, Dolby Digital and Dolby Digital Plus decoding from HD, SDI and AES signal sources. PAM2 Mk2 is equipped with an SDI output which exports the bargraph, data and Loudness Histogram displays to an external monitor (such as a multiviewer or video display) for ‘at a glance’ review of mission critical audio information.
‘Our older equipment was severely limited in performance, so we decided it was time to upgrade our confidence monitoring systems,’ says Chu Cun, Head of Technical Operations at BTV. ‘The TSL PAM2 Mk2 gives us the power to monitor loudness for compliance with new broadcast standards, accurately meter audio for many sources and provide phase information. In addition to full implementation of current Dolby standards and the capability to interface with multi-layered confidence monitoring systems, the units offer free software upgrades as new features are added.’
As a member of the Dolby OEM Partner Program, the PAM2 Mk2 was one of the first units to feature the optional Dolby CAT1100 module for comprehensive decoding and monitoring of Dolby audio formats that are used throughout the HD broadcast chain (Dolby Digital Plus, Dolby Digital and Dolby E). The new module enables the PAM2 Mk2 to perform Dolby E decoding and external speaker monitoring, as well as Dolby Digital Plus with descriptive audio and stream mixing, which will evolve to 7.1 as broadcasters adopt the full cinematic experience.
The government owned-and-operated television station rovides arts, science, lifestyle, finance, sports and news programming to more than 20,500,000 viewers over ten primary TV channels.
