Selecting the DCC mode
The NX5 is capable of several DCC modes (see Editing, Creating and Deleting Presets, on page 3.2.59 ),
each with varying performance in terms of energy savings and effects on the reproduced signal. The
selectable options are:
 AMC (see Figure 3.2.54 )
 EAMC (see Figure 3.2.55 on page 3.2.71 )
 DAM (basic) (see Figure 3.2.56 on page 3.2.71 )
 DAM Full (see Figure 3.2.57 on page 3.2.72 )
 DCC1 (see Figure 3.2.58 on page 3.2.72 )
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
