System Configuration

Step 2. Select one of the two options shown based on the way you wish to have the system settings entered:

•In most cases, you will want to use the Automatic mode, which calibrates the system for speaker presence, speaker “size”, speaker crossover, channel output level, speaker-to- listener delay time and room equalization. To choose this mode simply press the Set Button F, as the cursor is already pointing to

AUTOMATIC EQ DESIGN when the menu appears on the screen.

Then press the Set Button F again when the AUTOMATIC EZSET/EQ menu appears, to continue to Step 3.

•If you wish to enter the speaker crossover frequencies yourself, but want to have the EzSet/EQ system test for and calibrate all the other functions listed above, press the ¤ Navigation Button E to point the cursor at EZSET/EQ SETUP and then press the Set Button F. Once the MANUAL SETUP menu (Fig. 18) appears, follow the instructions on page 32 to enter your desired settings for the Crossover Frequencies, and then return to the EZSET/EQ MAIN menu. Press the ¤ Navigation Button E again so that the cursor is pointing to MANUAL EQ DESIGN and then press the Set Button F. When the interim message screen appears to remind you to set the crossovers, make sure that the cursor is point- ing to CONTINUE and press the Set Button F again since you have already set the crossovers.

Step 3. The FAR FIELD MEASURE screen (Figure 17b) will appear with instructions 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 vol- ume level to –35dB, as shown on the line that appears at the bottom of the menu when the volume is adjusted. Press the Set Button F when the volume is set to the proper level.

Step 4. The final menu screen before the EzSet/EQ process starts is a warning screen (Figure 17c) 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 ventila- tion 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 recommend that you rerun EzSet/EQ. If you do not wish to start the test process at this time, press the ⁄/¤ Navigation Button E to return to either the EzSet/EQ menu or the Master Menu, and press the Set Button F. To begin the EzSet/EQ Near Field measurements, press the ‹ / › Navigation Button E so that ON is highlighted in reverse video, and press the Set Button F.

NOTE: Once the EzSet/EQ 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 on-screen message change to indicate that EzSet/EQ is finished.

Step 5. 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 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 displayed as shown in Step 6 or 7, below.

NOTE: While these tests detect whether a speaker is connected to a particular output, they cannot determine whether the speaker is in the correct position. (For example, it can tell whether a speaker is connected to the Surround Right output, 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 on-screen message, make a note of the incorrect speaker connections. When the test process stops you will see a message indicating the they Far Field measurements are complete, but since there is a connection error press the ¤ Navigation Button E so that the on-screen cursor in Fig. 7 is pointing to RETURN TO MASTER MENU and press the Set Button F. At this point, exit all menus and turn the receiver off. Check all speaker wire connections and then rerun EzSet/EQ.

Step 6. When the Far Field tests are complete a message screen will appear to confirm if the pro- cedure was successful or not. In most cases there will not be any problems and you will see the message shown in Figure 17d on your screen. If the speaker positions shown match the actual speaker layout in your system, press the Set Button F to complete EzSet/EQ by performing the Near Field Measurements. Continue the EzSet/EQ process by pressing the Set Button

Fto take the Near Field measurements from the front left, center and right speakers. By taking this separate set of measurements, the AVR is able to complete its view of the room’s sonic signature and apply equalization as needed to correct spikes and dips in the system’s response. Continue these instructions with Step 8.
