Dithering and word length settings for digital output
Function
When digitally outputting a 24 bit song,
you can turn dithering on/off and spec-
ify the word length for dithering.
Key operation
• [SETUP] key [F3] (Dither Out) key
• Repeatedly press the [SETUP] key
until the screen shown at the right
appears.
Screen functions
A
ON/OFF (Dithering on/off)
Turn dithering on/off for the DIGITAL STEREO
OUT connector (DIGITAL ST OUT) and the output
channels of the OPTION I/O slot (OPTION OUT
SLOT).
Tip!
• When sending digital audio from a system with a
high number of bits to a lower system (e.g., 24 bits
16 bits), "round-off" of the bits may cause unpleas-
ant quantization noise. This is the reason that dither-
ing is applied to add a very small amount of noise to
the signal, so that quantization noise will not be as
obtrusive.
• When sending audio from a lower-resolution system
to a higher-resolution system (e.g., 16 bits
or when sending audio between systems of identical
resolution (e.g., 16 bits
on will have no effect.
• For digital I/O cards, dithering is switched on/off by
pairs of adjacent odd-numbered
channels (1/2, 3/4, ...).
B
WORD LENGTH (BIT)
Specify the word length (number of bits) of the sig-
nal that is sent from channels for which dithering
is turned on.
Tip!
For example if you want to send a 24 bit song to a 16
bit external recorder with dithering applied, you
would set the corresponding channels to Dither = on,
Word Length = 16.
Changing the word length of a channel for which dith-
ering is turned off will have no effect.
