Changing The Dsp Parameters - Meridian 861v8 User Manual

Changing the DSP parameters

Each DSP preset provides a series of parameters that
you can vary to customise the behaviour of the preset
to your specific requirements. For example, most
presets provide Balance and Depth parameters to
allow you to alter the characteristics of the sound.
For each of the built-in DSP presets these parameters
are set to standard values, designed to give the best
sound in typical listening conditions and with most
source materials. Each time you select a different DSP
preset the parameters are reset to these standard
values, even if you have previously altered them.
Parameter Range
Treble* -10dB to +10dB
Bass* -5dB to +5dB
Phase* + or -
Axis -2 to +3

HS Out?* Y or N
Centre -3.0dB to +3.0dB
Depth -2.5ms to +5ms
C.Elev Off, Min, Med, Max

* These parameters apply to all DSP presets.
Individual DSP presets provide additional parameters, to allow you to adjust specific features provided by that
preset. For full details refer to DSP presets , page 27.
Note: Parameters not relevant to your configuration are omitted from the sequence of menus.
You can save the changes you have made to one or
more DSP parameters in place of the original DSP
preset. Alternatively you can create a new user-defined
DSP preset with a name of your choice. User-defined
presets appear in the list of DSP presets after the
built-in ones. For more information about doing this see
Defining your own presets , page 26.
