Manual Setup

The AVR 354 is flexibly designed to be used with almost any loud- speakers available. The flexibility comes from the AVR 354’s capability to be configured to match the characteristics of your particular speakers, and to compensate for the acoustic characteristics of your room.

The EzSet/EQ process automatically detects the capabilities of each speaker, and optimizes the AVR 354’s performance in your system. However, if for some reason you are unable to run EzSet/EQ calibration, e.g., you have misplaced the microphone, or if you wish to make further adjustments to the settings made by the EzSet/EQ process, you may use the Manual Setup on-screen menus as described in this section.

Before beginning manual setup place your loudspeakers in their correct locations within the room (see Speaker Placement section), and connect them to the AVR. You will need the specifications for each of your speakers, which may usually be found in the owner’s guide for the speakers or on the manufacturer’s Web site. If necessary, contact the manufacturer to obtain the frequency range specification. Although the output-level setting portion of manual setup may be performed “by ear,” we recom- mend that you purchase an SPL (sound-pressure level) meter at a local electronics store.

We suggest that you record your configuration settings in the appropri- ate places in Tables A3 through A11 in the appendix in case you need to reenter them 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, we rec- ommend selecting a video output resolution of 720p or higher to provide graphics that simplify configuration. Those menus will vary in appearance from the ones shown here.

Step One – Determine Speaker Crossover

Without using the EzSet/EQ process, the AVR 354 can’t detect how many speakers you’ve connected to it; nor can it determine their capa- bilities. For this part of the system setup consult the speaker’s technical specifications.

Locate the frequency response, which is usually given as a range, e.g., 100Hz – 20kHz (±3dB). This specification tells you whether the speaker is able to play sounds that are very high- or low-pitched, represented by the high and low frequencies. We are concerned here with the lowest frequency that each of your main speakers is capable of playing, which is 100Hz in this example. Use the Table A3 worksheet in the appendix to note this number as the crossover for that speaker (not the same as the crossover frequency listed in the speaker’s specifications).

The subwoofer’s frequency response will include only the very lowest frequencies, since the subwoofer is designed to play only bass materials. A typical frequency response for a subwoofer is 25Hz – 150Hz. In this case, the higher number should be noted in the worksheet.

This information is required to program the receiver’s bass manage- ment, which determines which speakers the receiver will use to play back the low-frequency (bass) portion of the source program.

If you send the lowest notes to small satellite speakers, you won’t hear these notes very well, and you may even damage the speaker by exceeding its capabilities. If you send the highest notes to the special- purpose subwoofer, you may not hear them at all.

With proper bass management, the AVR 354 divides the source signal at a crossover point. All information above the crossover point is played through the satellite speaker (front left/right, center, surround left/right, or surround back left/right), and all information below the crossover point is played through the subwoofer. This enables each loudspeaker in your system to perform at its best, delivering an enjoyable sound experience.

Step Two – Measure Speaker Distances

Ideally, all of your speakers would be placed in a circle, each at the same distance from the listening position. However, your room may not be ideal, and you may have had to place some speakers a little further away than others. This could affect the overall sound of the receiver, as sounds that are supposed to arrive simultaneously from different speakers blur due to different arrival times.

The AVR 354 has a delay adjustment that enables the receiver to compensate for real-world speaker placements.

Before you begin making adjustments, measure the distance from each speaker to the listening position, and note it in the Table A4 worksheet in the appendix. Even if all of your speakers are the same distance from the listening position, you should enter your speaker distances as described in Step Three.
