System Configuration
Step 2: The EzSet/EQ microphone should be placed in either your usual listening position or, if there is a large seating area, the center of the room, at the listeners’ ear level. You may find it convenient to use a camera tripod for stable placement of the EzSet/EQ microphone at the correct height. The microphone includes a threaded insert on the bottom for tripod mount- ing.
Step 3: Plug the EzSet/EQ microphone into the AVR 347’s Headphone Jack 4, making certain that the mini-plug to 1/4" phone plug adaptor supplied with the microphone is firmly connected. The microphone cable is approxi- mately 7 meter long, which should accommo- date most listening room situations. If required, you may use an optional extension cable, avail- able at most electronics stores, for use in larger rooms. However, we recommend that you avoid using extension cords for the microphone cable, as they may adversely affect the test results.
Step 4: Once the microphone is properly posi- tioned and plugged in, proceed to the EzSet/EQ menus by first pressing the OSD Button L to bring the main Menu to the screen. Next, press the ⁄/¤ Navigation Buttons D to high- light the Speaker -tab in white, and press Set F to access the SPEAKER SETUP. Press the ¤ Button D to select the Auto Configuration -line and press the Set Button F to move to the next screen (Figure 14).

Step 5: The first screen of the EzSet/EQ system will now appear to remind you to plug in the microphone. If you have not already done so, plug the microphone into the Headphone Jack
4as described in steps 2 and 3. When you are ready to proceed, make certain that the cursor is pointing to Continue and press the Set Button F. If you do not wish to continue with the EzSet/EQ process, press the ‹/›
Navigation Buttons E to highlight
Cancel and then press the Set Button F to return to the SPEAKER SETUP.

Step 6: After you select “Continue”, the screen shown in Figure 15 will appear. Although the AVR may be used with up to eight speakers, you may have elected not to install surround back speakers at this time, or you may have decided to use the surround back speaker channels to power speakers in the remote room of a multi- room system. This screen directs you to program EzSet/EQ for a 5.1- or 7.1-channel configuration. Select the setting that reflects the number of speakers installed in your system, and EzSet/EQ will do the rest automatically!
NOTE: If you are using fewer than six speakers in your system, then it will not be possible to configure your speakers using EzSet/EQ, and you will need to select Manual Configuration as described starting on page 31. If you have selected a 6.1-channel configuration, using only a single surround back speaker, it is possible to use a combination of EzSet/EQ automatic configuration for 5.1 speakers, connect the single surround back speaker to the left Surround Back Speaker Output, and then configure the surround back speaker manually, as described from page 31. However, we do not recommend the 6.1-channel configuration.
If you have forgotten to plug in the EzSet/EQ microphone, the warning screen shown in Figure 16 will appear as a reminder.
Figure 16
NOTE: As shown in Figures 14-22, while EzSet/EQ is in progress a Cancel setting is highlighted. You may interrupt EzSet/EQ at any time by simply pressing the Set Button F.
IMPORTANT NOTE: Anyone with hearing that is sensitive to loud noises should leave the room at this point, or use ear protection sufficient to reduce the noise level. Inexpensive foam-style ear plugs, available at most drug stores, may be used to reduce the sound level to a tolerable level. If you are uncomfortable with, or cannot tolerate, loud sounds and do not use some sort of ear protection, we strongly recommend that you leave the room and ask someone else to run the EzSet/EQ process, or that you do not use EzSet/EQ and enter the configuration settings manually, as described on pages 31 through 34.

Step 7: Once EzSet/EQ has been started, you will hear test signals circulate among all of the speakers as the system sets the master level, checks to see where there are speakers, sets the distance measurement and calculates delay time settings, sets the speaker “size”, and sets the speaker crossover point. During the measure- ment and calibration process, you may observe the progress of the testing by reading the messages that appear in the second line of the menu listing.
EzSet/EQ uses the left front speaker to set the master volume level, and then it proceeds directly to measuring the speaker output levels.
Speaker Level: During this test, EzSet/EQ ensures that all speakers sound equally loud at the listening position. During a surround sound presentation it is common for the surround channels to sound less prominent, or not to be used at all at times. By setting the baseline channel levels correctly, the AVR behaves as a blank canvas for the movie director to create special effects.
A screen similar to the one shown in Figure 18 will appear, with the speaker position changing as EzSet/EQ measures the levels for each speaker. You may occasionally hear EzSet/EQ send a tone back to the front left speaker. This enables EzSet/EQ to compare the level of the speaker being measured to the reference level it set for the front left speaker.
