RTW adds BLITS testing12 July 2013
RTW has introduced a new BLITS instrument option for its line of TM7 and TM9 TouchMonitors. Part of the SW20013 software license recently issued by the company, the BLITS instrument is designed to generate and analyse BLITS test signals.
BLITS (Black & Lane’s Ident Tones for Surround) enables testing for channel allocation, level and phase of 5.1 surround signals. RTW created a special instrument not only to generate a BLITS test signal, but also to use the BLITS sequence for a user-friendly and comprehensive analysis and display of level, channel allocation, phase, delay and polarity of incoming digital audio signals in 5.1 mode. Adjustable limits complement the analyser, and the sequence can be accessed from any digital input of the TouchMonitor.
The BLITS instrument also features a signal generator capable of generating the 5.1 sequence as well as a stereo ident sequence either in EBU 3304 format or as the widely known GLITS tone. A user can choose to place an identification header, similar to a station ident, in front of the test sequence. The signal will then be output through the AES 3 or AES3id output feeds.
