System Configuration
During each EQ Design step, you have the option to perform the tests for that specific portion of the process, or you may skip the settings and move to another step or return to the EZSET/EQ MAIN menu (Figure 12).
When the complete EQ Design process is complete, you will be given an opportunity to “test drive” the settings by listening to a source with the room equalization filters applied. In order to take advantage of this feature, before beginning the EQ Design, make certain that a source is playing with program material you are familiar with. If necessary, exit the menu system at this time to select and start the playback, and then return to EzSet/EQ II. The source will mute during the EQ Design, but will return when it is time for the “test drive.”
Step 1. The EZSET DESIGN STEP 1
menuscreen (Figure 13) will appear with instruc- tions to place the microphone, if you have not already done so. This screen is also the place to set the master volume level. As noted on the
screen, use the Volume Control ı to adjust the volume level to

The final menu screen before the EzSet/EQ process starts is a warning screen (Figure 14) that serves as a reminder to keep the room as quiet as possible while the system is in use. Extraneous noise of any kind may adversely affect the accuracy of the system’s results. Do not talk while the test tones are circulating, and if possible, turn off any ventilation systems if the noise form the air flow is loud enough for you to hear. Should an outside noise such as a phone ringing occur during the test process, we recom- mend that you rerun EzSet/EQ II. If you do not wish to start the test process at this time, press the ⁄/¤ Navigation Button DF to return to either the EzSet/EQ II menu or the Master Menu, and press the OK/Enter Button
Eon the TC 30 or the Set Button Q. To begin the EzSet/EQ II Near Field measurements, press the ‹ / › Navigation Button DF so that ON is highlighted in reverse video, and press the OK/Enter Button E on the TC 30 or the Set Button Q.
NOTE: Once the EzSet/EQ II process starts, the volume control and Standby/Off switches are temporarily disabled while the tests are in progress. Do not adjust the volume or turn the unit off until you see the

At this point you will begin to hear a series of test tones circulate among all the speakers in your system. While this is happening, the AVR 745 is reading the signal to determine which speaker positions are active, what type of speaker is present at each active position, what the distance is from the listening position to each speaker, and to begin to build a profile of the impact of the room’s acoustics on the quality of audio reproduction. When the test is completed you will hear the tones stop, and the system will pause fors long as a minute while the processor makes its calculations. Do not be alarmed if the “WARNING” message remains on the screen after tones stop until a results message is dis- played.
NOTE: While these tests detect whether a speak- er is connected to a particular output, they can- not determine whether the speaker is in the cor- rect position. (For example, it can tell whether a speaker is connected to the Surround Right out- put, but it cannot tell whether the speaker is on the right or left side of your listening room.) For that reason, we strongly recommend that you try to listen as the tone circulates, matching the name shown for each channel to the location of the speaker. If a tone is heard from a speaker position that does not match the
Eon the TC 30 or the Set Button Q. At this point, exit all menus and turn the receiver off. Check all speaker wire connections and then rerun EzSet/EQ II.
When the Far Field tests are complete a message screen will appear to confirm if the procedure was successful or not. In most cases there will not be any problems and you will see the mes- sage shown in Figure 15 on your screen. If the speaker positions shown match the actual speak- er layout in your system, confirm that the cursor is pointing to CONTINUE TO NEAR FIELD and press the OK/Enter Button E on the TC 30 or the Set Button Q to take the Near Field measurements in Step 2.

Figure 15
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 16. EzSet/EQ is programmed 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 speak- er is present. Should this message appear, make note of the suspect speaker location, exit all menus and turn the receiver off. Check all speak- er wire connections and then rerun EzSet/EQ.
