After a few seconds, the red bar turns yellow and will remain until you reset it. Note
that when a CRC error first appears, the Menu button becomes the Reset CRCs
button.
1. Decode: Either rotating or pressing this knob selects the Dolby stream to
decode. The available options include: All Formats, Dolby D Only, or Dolby E
Only. This is especially useful for signals that often switch between PCM and
E or D. There will be a 1- frame burst of noise for every switch between PCM
and D or E, unless this menu item is set to either Dolby D Only or Dolby E
Only.
For some applications, only one form of Dolby should be decoded and all
others should be muted. If the same type of Dolby bitstream is always
expected, then select that type. However, if any of the other formats can be
expected to appear at various times and must be decoded, then select All
Formats.
2. Aux Pair: Either rotating or pressing this knob determines how the auxiliary
Dolby pair will be treated. The available options include: Mute, Mono, LoRo
Downmix, or LtRt Downmix.
The fifth (AUX) channel pair of the Dolby decoder can be tasked with
outputting one of several downmixes:
a) LoRo Downmix: This a downmix of the selected surround program
that forms a stereo signal in which the surround channels are
combined. The resulting signal can be used to play a representation of
the surround sound signal in stereo headphones or stereo speakers.
You can also downmix this signal again to mono.
b) LtRt Downmix: This is a downmix of the selected surround program
that sums the surround channels and adds them with a +90° phase
shift to the left channel and a -90° phase shift to the right channel. A
Dolby Surround Pro Logic decoder can then be used on this signal to
reconstruct the surround channel. However, while the result of this
