Setting Loudness “By Ear”
When setting loudness by ear, it is essential the system gain structure be set up first. Sit in
an average (but somewhat prominent) listening location.
1.
Set the loudness processor to
Bypass
.
2. Set the output volume fader in the DSP Configurator to a relatively quiet listening
level. Filter compensation from the loudness processor is most prominent at low
listening levels. Use familiar program material set to the levels described earlier.
3.
The
Calibrate
slider should be set to 0, the center point. Disengage the loudness
Bypass
. The result will be a moderate enhancement to the program material, with
more accentuated bass frequencies (below 500Hz), and more brightness in the
high frequencies that carry harmonic content (above 7kHz). Engage and disengage
the
Bypass
switch in order to “A/B” the difference between loudness off and on,
respectively.
4. To experiment with less loudness compensation, move the loudness compensation
slider to the left (less). For more loudness compensation, move the slider to the right
(more).
5.
Any adjustment made to the loudness compensation slider will carry through to all
listening levels. Set the output volume fader in the DSP Configurator to a relatively
loud listening level.
6. Engage and disengage the
Bypass
switch in order to “A/B” the difference between
loudness off and on. At a loud listening level, the difference should be minimal or
barely perceivable.
Delay
Delay function and interface is identical to the line Input channel delay block, described in
mic/line input section,
Delay
.
Filter
Filter function and interface is identical to the line input channel filter block, described
in mic/line input section
Filter
. However, there are a total of nine filters allowed in the
output signal processor chain.
Dynamics
Dynamics function and interface is identical to the line input channel dynamics block,
described in mic/line input section
Dynamics .
