3. Dynamic EQ:
the sound of an audio system may very according to the reproduction volume. At low volume,
the noises coming from outside the vehicle and the especially insulated acoustic within the car compartment
contribute to limit (especially in low frequency) the system’s performance. Generally during calibration you need
to consider that the adjustments performed with low level volume may change relentlessly when the volume will
be increased.
The
Dynamic Equalization
improves the listening actively operating on the variation of the frequency response
as a consequence to the volume change.
The Wizard will suggest a series of windows to set up the equalization to be applied to the general frequency response.
The bit One HD Virtuoso will automatically perform a gradual data interpolation, following the signal level and
therefore acting according to the system volume. Two operating modes are available.
To use this function click on the button to the left of the menu until the orange led lights up. To disable the
function click again on the button until the orange led turns off.
Phase ON/OFF
By clicking on the Phase on/off key, it is
possible to enable or disable the correction
of the phase applied to the Head Unit
connected to the bit One HD Virtuoso. The activation is successful when the led light becomes red.
Restore Phase Alignm suggestions:
If an “AUTOMATIC MASTER DE-EQ / PHASE
Analysis” was performed and new valued
are then edited, it will be possible to restore
the phase compensation values suggested
by the software
.
Total Electric Response.
The chart shows the electrical sum of the
channels selected in the menu “Trace Curve”.
If a “Phase Analysis” was performed
(see xxxxxx)
, two curves will be displayed. The
Blue curve refers to the trend of the selected
fronts, where the presence of All-Pass filters
can be shown, provided by one or more holes
in the frequency domain, while the orange
color refers to the fronts compensation via
All-Pass filters. If the Phase Analysis was not performed, only the orange curve resulting from the modifications
made via All-Pass adjustment will be displayed.
To set up the dynamic equalizer click on the button to the right of the menu and proceed as follows:
EASY MODE
Insert a CD in the source and play a reference
track. Select the
Easy
operating mode. A
semi-automatic procedure will start. Move
the Volume slider setting the low volume
listening reference level.
After adjusting the slider, select
START
.
Move the
EQ
slider to set up the low volume
response equalization until the desired
sound is achieved. In this case the
equalization curve which applied is pre-set.
When reaching the desired setting select
SAVE
. At this point the reference curve for
low volume listening will be applied.
