Selecting the DCC mode
The NX300 is capable of several DCC modes (see
"Editing or Creating Presets", on page 2-49
), each
with varying performance in terms of energy savings and effects on the reproduced signal. The
selectable options are:
•
AMC (see
Figure 2.40
)
•
EAMC (see
Figure 2.41 on page 2-58
)
•
DAM (basic) (see
Figure 2.42 on page 2-58
)
•
DAM Full (see
Figure 2.43 on page 2-59
)
•
DCC1 (see
Figure 2.44 on page 2-59
)
Once a DCC curve has been selected, the desired
Max DCC Compression
level can be entered. This
setting defines the maximum reduction in carrier (or carrier and sideband) power for a given curve.
Standard compression settings are as follows:
•
AMC and EAMC modes: 3 dB
•
DAM, Full DAM and DCC1 modes: 4.44 dB
