| To
perform 2.2 mode automatic room correction
go through the following steps: |

2.
Crossover Filters OFF. Make sure that crossover filter option is
set to OFF. It is important that all measurements
are performed without any crossover filtering.
If your loudspeakers have built in electronic
crossover filters, make sure that they are
disabled. If crossover filters could not be
disabled, set the subwoofer crossover filter
to its highest frequency and main channel
to its lowest cut off frequency.
To disable crossover filters enter the RCS-DRC menu and select the CRO-ON(OFF) option in Fig.3 to enter Crossover screen
Fig. 4.
Crossover filters can be turned OFF from the
front panel crossover menu (Fig. 4). Place
the screen cursor over the CRO: ON menu option and then press the enter button
(click) until it displays CRO: OFF,
and then click on SET option.
Please note that any change made on this screen
does not take effect until you click on the SET option.
Click on the MENU button to go back to the
DRC-RCS screen, Fig. 3. |

Measurements. To perform
room response measurements select the MSR
menu option to display measurement screen
(Fig. 5).

4.
Enable automatic room
correction. In the DRC-RCS screen (Fig. 3), select correction preset
1. Make sure that crossover filters are enabled
and proper crossover frequency is selected.
Crossover filters can be adjusted at any time
even after you enable the automatic feature.
Click on the AUTO-OFF menu
option to enter the Auto Correction screen
(Fig. 6). Note that in bypass mode the AUTO-OFF(ON)
menu option is not displayed.
In the Auto Correction screen click on the
AUTO-OFF menu option to display AUTO-ON and
then click on the SET option to activate automatic
room correction. In a split of a second the
2.2 XP will calculate target curves based
on LF, HF, crossover filter selection parameters
and measurement data as saved in measurement
file 1.
You are ready to perform your first listening
test. Use LF parameters to add gain or attenuation
at frequencies bellow the frequency as displayed
in LF parameter bloc (1). Use HF parameters
to add gain or attenuation to frequencies
above the frequency as displayed in HF parameter
block (2). In this way you can shape target
curves to match your specific listening needs.
Please note that changes you make on this
screen do not take effect until you click
on the SET option. |
