its output word length to 18 or 16 bits. If the input material is insufficiently
dithered for these lower word lengths, the 6200 can also add dither. (See the
next step.)
A)
Press the
Next
button to page to the Digital Output Calibration screen with
Word
Len
displayed, then adjust the parameter, as necessary.
11. Adjust DITHER to on or off, as desired.
[on] or [off]
The 6200 can add “high-pass” dither before any truncation of the output
word. The amount of dither automatically tracks the setting of the
WORD
LEN
control. This is first-order noise shaped dither that reduces added noise
in the midrange considerably by comparison to white PDF dither. However,
unlike extreme noise shaping, it adds a maximum of 3dB of excess total
noise power when compared to white PDF dither. Thus, it is a good com-
promise between white PDF dither and extreme noise shaping.
In many cases, you will not need to add dither because the source material
has already been correctly dithered. However, particularly if you use the
Noise Reduction feature, the processing can sometimes attenuate input dither
so that it is insufficient to dither the output correctly. In this case, you should
add dither within the 6200.
12. Set STAT BITS (Status Bits) mode.
[AES/EBU], [SPDIF]
This control determines whether the status bits supplied at the digital output
are in Consumer (SPDIF) or Professional (AES/EBU) mode.
13. End I/O CALIB programming.
When you are finished adjusting input/output parameters, repeatedly press the
Escape
button to return to the Idle G/R screen.
14. Select the program format of your station.
This step selects the processing to complement the program format of your
station.
After this step, you can always select a different processing preset, program
the 6200 to automatically change presets on a time/date schedule, modify pre-
sets to customize your sound, and store these presets as User Presets.
A) Press the Recall button.
B)
Use the knob to scroll through the list of Factory Programming Presets.
C)
When you have found an appropriate preset, press the
RECALL NEXT
soft key.
Your chosen preset is now on the air.
