RTW SW20013

Product description

BLITS (Black & Lane's Ident Tones for Surround) enables testing for channel allocation, level and phase of 5.1 surround signals. Developed in 2004 by Martin Black and Keith Lane at London's Sky TV, this sequence has gained widespread adoption in international broadcasting.

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 analyzer, and the sequence can be accessed from any digital input of the TouchMonitor.

In addition to the analyzer, the BLITS instrument features a signal generator. This feature 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. 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.

The BLITS license option for TM7 and TM9 and requires users to install the current firmware, version 3.10, first. Users can download the firmware for free by logging in to RTW's website: http://www.rtw.de/en/sales-support/manuals-software.html.
