The last section consists of 2 kHz tone at -24dBFS on all six channels. This can be used to check phase between any of the 5.1 legs. When the tone is summed to stereo using default down-mix values this section should produce tones of approximately -18 dBfs on each channel. The BLITS sequence repeats approximately every 14 seconds.
