| To perform 2.2 mode automatic room correction go through the following steps: |
| 1. Correction Bypass. Place 2.2 XP in correction bypass mode. You can place 2.2 XP in bypass mode by pressing on the BP remote control button or by using the front panel controls. |

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. |

3. Measurements. To perform room response measurements select the MSR menu option to display measurement screen (Fig. 5).
The 2.2 XP is factory configured to measurement parameters as displayed in Fig. 5. The MSR MIC CAL option should be turned ON and the MIC FILE field should display the microphone serial number as printed on your microphone. |

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. |
