Selecting the DCC mode
The NX50 is capable of several DCC modes (see "Editing or Creating Presets", on page 2-50 ), each
with varying performance in terms of energy savings and effects on the reproduced signal. The
selectable options are:
• AMC (see Figure 2.43 )
• EAMC (see Figure 2.44 on page 2-61 )
• DAM (basic) (see Figure 2.45 on page 2-61 )
• DAM Full (see Figure 2.46 on page 2-62 )
• DCC1 (see Figure 2.47 on page 2-62 )
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
