BLITS - A New Optional Tool for TouchMonitor
TC Electronic now introduces a new, optional 5.1 surround
instrument for its TouchMonitor. This option incorporates a BLITS
instrument for generating and analyzing BLITS test signals.
BLITS (Black & Lane's Ident Tones for Surround) is a tool that allows for testing channel allocation, level and phase of 5.1 surround signals. Developed by Martin Black and Keith Lane from Sky TV in London in 2004, this sequence is widely used in international broadcasting.
This special instrument was created to not only generate a BLITS
test signal, but to also 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 analyzer. The
sequence can be acquired from any digital input of the
Apart from the analyzer, the BLITS instrument features a signal generator part that is capable of generating not only the 5.1 sequence, but also a stereo ident sequence either in EBU 3304 format or as the widely known GLITS tone. An identification header like a station ident can be placed optionally in front of the test sequence. The signal will be output through the AES 3 or AES3id output feeds.
