EXT
[14], [16], [18], [20], or [24], in bits
The largest valid word length in the 6300 is 24 bits
The 6300 can also truncate its output word length to 20, 18, 16 or 14 bits.
The 6300 can add dither (see the next step).
H) Adjust DO1 D
[In] or [Out]
When set to In, the 6300 adds "high-pass" dither before any truncation
of the output word. The amount of dither automatically tracks the set-
ting of the W
erably reduces added noise in the midrange by comparison to white PDF
dither. However, unlike extreme noise shaping, it adds a maximum of 3
dB of excess total noise power when compared to white PDF dither. Thus,
it is a good compromise between white PDF dither and extreme noise
shaping.
To ensure maximum system linearity, it is wise to set this control to I

 AGC+LIM (stereo enhancement, equalization, AGC, and look-ahead peak
limiting)

Band compression without peak limiting)
 MB+LIM (stereo enhancement, equalization, AGC, 2-Band or 5-Band com-
pression, and look-ahead peak limiting)

assign each program to a separate digital output. In this case, both chan-

and both channels of DO2 emit the right channel material.
