50 50ADVANCED FUNCTIONSbe played through the front left and right speakers and the speciallow-frequency effects (LFE) channel information.LFE: This setting plays low-frequency information contained in theleft and right program channels to the front speakers, and directsonly the LFE channel information to the subwoofer.NOTE: If you are using a Harman Kardon HKTS Series speakersystem, select the appropriate numeric crossover frequency forthe Left/Right, Center, Surround and Surr Back lines, and thesubwoofer will automatically be set to LFE.The Speaker/Channel Indicators on the front panel of the receiver (seeFigure 63) will display the speaker size settings as follows. For eachspeaker configured numerically, a single box will appear in the positionfor that speaker. For each speaker configured as LARGE, a double boxwill appear in its position. If a speaker is configured as OFF, no box willappear. The subwoofer will be indicated by a single box, or no box ifno subwoofer has been configured. The letters inside the boxes appearwhen a digital signal is being received that has that channel discretelyencoded. The letters flash when the signal is not present, such as whena DVD is paused. A line will connect the SBL and SBR boxes when a6.1-channel signal is detected, indicating that the same signal is playingthrough both speakers.Adjust Speaker Distance MenuAs explained above in Step Two – Measure Speaker Distances, some-times the speakers are placed at different distances from the listeningposition, which can muddy the sound, as sounds are heard earlier orlater than desired.Even if all of your speakers are placed the same distance from thelistening position, do not skip this menu.On the Manual Speaker Setup menu, move the cursor to the Distanceline and press the Set Button to display the Adjust Speaker Distancemenu. See Figure 68.Figure 68 – Adjust Speaker Distance MenuThis menu requires you to enter the distance from each speaker to thelistening position, which you measured in Step Two – Measure SpeakerDistances and noted in Table A4 in the appendix.The default unit of measurement is feet. If you wish to change the unitto meters, press the Back/Exit Button until you return to the main AVRmenu. Scroll down to the System line, and select it to view the SystemSettings menu. Scroll down this menu to the General AVR Settingssection, and select the Unit of Measure line. Press the OK Button tochange the setting from Feet to Meters.Use the ⁄ /¤ Buttons to move the cursor to the Front Left line, pressthe OK Button then use the ‹/ › Buttons to change the measurementas needed. The values vary between 0 and 30 feet, with a default of10 feet for all speakers. Use the ⁄ /¤ Buttons to move to eachspeaker in turn – Center, Front Right, Surround Right, Surround BackRight, Surround Back Left, Surround Left and Subwoofer, if present inyour system.NOTE: When the multiroom system is in use, if the surroundback channels are assigned to the multiroom system, you willnot be able to adjust the delay settings for these channels, andthe cursor will skip past them.Step Four – Setting Channel Output LevelsManuallyFor a conventional 2-channel receiver, the balance control enables theuser to control the stereo imaging by adjusting the relative loudness ofthe left and right channels, as heard at the listening position.With up to seven main channels plus a subwoofer, imaging becomesboth more critical and more complex. Unlike the rotary balance control,the goal of the AVR 354’s channel output adjustment process is toexamine the output level of each channel independently and ensurethat each is heard at the listening position with equal loudness.If you followed the instructions in the Initial Setup section, then youlet EzSet/EQ calibration handle this critical task for you, simply andautomatically.However, if you prefer to make these adjustments manually, theAVR 354’s Adjust Speaker Levels menu allows you to do so, eitherusing the system’s test tone or while playing source material. In addition,this is the only method for adjusting the level of the subwoofer.If you use a handheld SPL meter (available at many electronics stores),set it to the C-Weighting, Slow scale.1. Make sure all speakers have been connected correctly.2. Adjust the number of speakers, crossover, distance and sub modefor each speaker in your system as described in Step Three.3. If you are using a handheld SPL meter with source material, suchas a test disc or another audio selection, play it now and adjust theAVR’s master volume control until the meter measures 75dB.4. There are several methods of adjusting the channel output levels,using either the test tone or source materials. In all cases, you maymeasure the channel levels in one of two ways:a) By ear. Try to adjust the levels so that all channels sound equally loud.b) Using a handheld SPL meter set to the C-Weighting, Slow scale.Try to adjust each channel so that the meter reads 75dB.
