The RB-TGHD is an 8 channel audio tone
generator that provides line identification for
multi-channel audio systems, including 5.1
and 7.1 surround sound typically used in high
definition television broadcasts. By using a
range of widely accepted industry standard
tone sequences such as the EBU R49, GLITS
and BLITS tones, channel identification and
associated levels can be determined easily.
Correct channel configuration in folddown
mixes can also be highlighted when
a broadcaster needs to mix several audio
channels into a stereo feed.
The RB-TGHD caters for 2, 4, 6 and 8 channel
configurations and all of the available
audio tone sequences for each channel
configuration can be cycled through
automatically, or selected manually, and
a loop mode allows patterns of tones to
be repeated.
