are unable to run EzSet/EQ II calibration, or if you wish to make further adjustments, use the Manual Speaker Setup on-screen menus.

Before beginning, place your loudspeakers as explained in the Speaker Placement section, and connect them to the AVR. Consult the owner’s guide for the speakers or the manufacturer’s Web site for the frequency range specification. Although you may set the out- put levels “by ear,” an SPL (sound-pressure level) meter purchased at a local electronics store will provide greater accuracy.

Record your configuration settings in Tables A3 through A12 in the appendix for easy re-entry after a system reset, or if the AVR’s Master Power Switch is turned off or the unit is unplugged for more than four weeks.

NOTE: When using the AVR’s Speaker Setup menus, select a video output resolution of 720p or higher to view graphics that simplify configuration.

STEP ONE – Determine Speaker Crossover

Without using the EzSet/EQ II process, the AVR 7550HD can’t detect how many speakers you’ve connected to it; nor can it determine their capabilities. Consult the speaker’s technical specifications and locate the frequency response, usually given as a range, e.g., 100Hz – 20kHz (±3dB). Write down the lowest frequency that each of your main speakers is capable of playing (100Hz in the example) as the crossover in Table A3 in the appendix. This is not the same as the crossover frequency listed in the speaker’s specifications. For the subwoofer, write down the transducer size.

The receiver’s bass management determines which speakers will be used to play back the low-frequency (bass) portion of the source program. Sending the lowest notes to small satellite speakers won’t sound right, and may even damage the speaker. The highest notes may not be heard at all through the subwoofer.

With proper bass management, the AVR 7550HD divides the source signal at a crossover point. All information above the crossover point is played through the satellite speaker, and all information below the crossover point is played through the subwoofer. Each loudspeaker in your system performs at its best, delivering an enjoyable sound experience.

STEP TWO – Measure Speaker Distances

Ideally, all of your speakers would be placed in a circle, with the listening position at the center. However, you may have had to place some speakers a little further away from the listening position than others. Sounds that are supposed to arrive simultaneously from different speakers may blur, due to different arrival times.

Use the AVR’s delay adjustment to compensate for real-world speaker placements.

Measure the distance from each speaker to the listening position, and write it down in Table A4 in the appendix. Even if all of your speakers are the same distance from the listening position, enter your speaker distances as described in Step Three.

STEP THREE – Manual Setup Menu

Now you are ready to program the receiver. Sit in the usual listening position and make the room as quiet as possible.

With the receiver and video display turned on, press the AVR Settings Button to display the menu system. Use the 5 Button to move the cursor to the Speaker Setup line, and press the OK Button to display the Speaker Setup menu. See Figure 21.

If you have run the EzSet/EQ II process, the results were saved in one of the two listening positions. Adjust the Speaker Setup setting in the Audio Effects menu to activate the results for either position (see page 45). To tweak the EzSet/EQ II results, or to con- figure the AVR from scratch, select Setup Listening Position 1 or Setup Listening Position 2. A screen similar to the one shown in Figure 28 will appear.

Figure 28 – Speaker Setup Position Menu

NOTE: All of the speaker setup submenus include the Back option, as shown at the bottom of Figure 28. To save the current settings, select the Back option.

To reconfigure the speakers from scratch, select the Reset option.

For best results, adjust the submenus in this order: Number of Speakers, Crossover (Size), Sub Mode, Distance and Level Adjust.

Number of Speakers

Move the cursor to the Number of Speakers line and press the OK Button. See Figure 29.

Figure 29 – Number of Speakers Menu

Program the correct setting for each speaker group: ON when the speakers are present in the system, and OFF for positions where no speakers are installed. The Front Left & Right speakers are always ON and may not be disabled. Any changes will be reflected in the total number of speakers displayed at the top of the screen.

The setting for the surround back speakers includes a third option: Zone 2. The AVR 7550HD is capable of multizone operation, supporting placement of a pair of speakers in another room. The AVR 7550HD’s assignable surround back amplifier channels make multizone operation
