AUDIO

The AUDIO soft key (F2) allows you to set certain parameters relating to the audio
outputs. Press AUDIO will give you this screen:
In this page, you may set the output format for the digital audio outputs. The INDIVIDUAL
field allows you to set the format for the individual digital outputs and you may choose
PROFESSIONAL or CONSUMER. PROFESSIONAL would be the choice to make when
interfacing with AES/EBU digital audio equipment whilst CONSUMER would be the choice
when connecting to DAT machines that use the SPDIF format of digital inputs.
NOTE: There is no equivalent page for the digital inputs because the DD1500's digital
audio receivers can automatically detect the format and adjust accordingly.
The DE-EMPHASIS softkey (F1/F2) will display this screen:
Here, you may switch de-emphasis on or off for the individual outputs or the MIX A/B
outputs.
Some digital recordings have pre-emphasis applied to them. These recordings have a
slight HF boost which needs to be cut (de-emphasised) during playback. This page allows
you to switch de-emphasis on or off as appropriate.
NOTE: If you are using a mixture of 'normal' digital recordings and pre-emphasised
recordings, please note that if any of the outputs have de-emphasis applied, 'normal'
recordings will sound a bit dull - this is because de-emphasis (i.e. HF cut) is being applied
to all recordings. The pre-emphasised recording will playback correctly. If, however, you
leave de-emphasis off, the 'normal' recording will playback properly but the pre-
emphasised recordings will sound a bit bright.
