After importing the HD parameters, you are still free to adjust any individual AM or
HD parameter. When you are satisfied with your work, you can then save this com-
bination of AM and HD parameters as a new User Preset. Of course, you can then
use your new User Preset as a source for HD parameters to be imported into any
other User Presets you may wish to create or edit. For example, you could have six
User Presets with identical HD processing parameters but with different AM analog
processing parameters. The HD bulk import feature makes this easy.
If you have not edited any parameters in a given HD Factory Preset’s dynamics proc-

will continue to be available even if that HD preset has been im-
ported into a User Preset and you are editing that User Preset. Moreover, you can
freely create multiple generations of User Presets that retain HD

func-
tionality. The only thing that counts is that the HD parameters in a given User Preset
are unchanged compared the original source HD Factory Preset.
In most of the analog AM factory presets, the associated processing for the digital
radio chain is much more conservative than the processing for the analog chain, al-
though the processing for the digital radio chain is still designed to be consistent
with the format named in the preset. This is to minimize codec artifacts in low bit
rate codecs like the HD AM HDC codec, which operates at 36 kbps. If you are using
the digital radio processing chain to drive a high bit rate codec (like 128 kbps MP3),
you usually can use a less conservative digital radio preset without introducing ob-
jectionable codec artifacts.
Each Orban factory preset has full

capability. There are separate

controls for the analog AM and digital radio presets. Table 3-1 shows the AM
analog presets, including the source presets from which they were taken and the
nominal

Important! If you are dissatisfied with the sound available from the fac-
tory presets, please understand that each named preset is actually 19 pre-
sets that can be accessed via the
