System Configuration

Step 7a. If the measurements are not successful due to a missing or malfunctioning speaker, the FAR FIELD EQ ERROR message will appear as shown in Figure 17e. EzSet/EQ is pro- grammed to look for speaker pairs at the front left/front right, surround left/surround right and surround back left/surround back right positions. If the test results indicate that one, but not both of the speakers in any of these pairs is present, the menu will show NO next to the speaker position where the tests did not report back that a speaker is present. Should this message appear, make note of the suspect speaker location, exit all menus and turn the receiver off. Check all speaker wire connections and then rerun EzSet/EQ.

Step 7b. In some cases, the system may not function properly due to overly high output levels. When this occurs, you will see the message shown in Figure 17f. If you see this message verify that that the microphone is in the correct position, and not too close to any one speaker. Then press the Set Button F to go back to the MASTER MENU. From there, return to the EzSet/EQ system and when you are once again at the FAR FIELD MEASURE screen, reduce the system volume level by 3dB before trying EzSet/EQ again.

Step 8. When the Far Field measurements are completed, the system will ask you to take three Near Field measurements, one at each front speaker position. These measurements enable EzSet/EQ to produce the most accurate settings for both high and low frequency equalization. The Near Field measurements are similar to the Far Field tests, except that the system will “listen” to only one speaker at a time, rather than sending the test signals to all speakers in rotation.

At the NEAR FIELD EQ SELECT menu (Figure 17g) that should be on your screen after completing the instructions in Step 6, press the Set Button F to start the near field measure- ments with the front left speaker. If you are repeating the setup process, you may also use the /¤ Navigation Button E to select any of the three speaker positions shown.

At the NEAR FIELD EQ SELECT menu (Figure 17g), you will see an instruction to place the microphone in a different position than the one used for the initial Far Field measurements. This time, place the microphone close to the speaker to be measured, at a distance of about 60 cm. In addition, the top of the microphone should be pointed towards the speaker, rather than pointing up as was done for the Far Field tests. For the first measurement, place the micro- phone so that it is close to, and pointing towards, the front left speaker, and with the on- screen cursor pointing to 1. FL SPEAKER, and press the Set Button F.

Step 9. You will now see a Warning message similar to the one shown in Figure 17c except that it will contain an option to return to the NEAR FIELD EQ SELECT menu (Figure 17g) as well as the ability to return to the MASTER MENU. If you are ready to proceed with the test, make certain that the microphone is properly pointed toward the speaker selected for calibration, press the Navigation Button

Eso that ON is highlighted and press the Set Button F.

Step 10. One short test signal will be sent to the speaker position being calibrated and after a slight pause fro the system to calculate the test results, you will see either a “Near Field Complete” message or a “Near Field Error” message. In most cases, the “Complete” message will appear, in which case you should proceed to Step 11, if an “Error” message appears, go to Step 12.

Step 11. If the test results were successful, the message shown in Figure 17h will appear. In order to properly calibrate the system, you will need to run the Near Field tests for all three front channel speakers (left, center and right). After running the test for the front left speaker, make certain that the cursor is pointing towards BACK TO NEAR FIELD and press the Set Button F. When you are taken back to the Near Field Select menu (Figure 17g) where you should repeat Steps 8 through 11 until all three front speakers have been calibrated. When that is done the EzSet/EQ process is complete and you should press the ¤ Navigation Button E to return to the Master Menu.

Step 12. If a “Near Field Error” message appears, as shown in Figure 17i, you should check to make certain that the microphone is about 60 cm from the speaker being tested and that the top of the microphone unit is pointing towards the speaker. You may also have to raise or lower the master volume to achieve accurate readings. After checking these two items, as needed, make certain that the cursor is pointing to the BACK TO NEAR FIELD line and press the Set Button F. This will return you to the NEAR FIELD EQ SELECT menu (Figure 17g) where you should repeat Steps 8 through 11, adjusting the mike placement and volume level as needed until the NEAR FIELD COMPLETE menu (Figure 17h) appears after the test tone stops.
