41ADVANCED FUNCTIONSSetting Channel Output Levels ManuallyFor 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 five main channels plus a subwoofer, imaging becomes both morecritical and more complex. Unlike the rotary balance control, the goalof the AVR 145’s channel output adjustment process is to examine theoutput level of each channel independently and ensure that each isheard at the listening position with equal loudness.If you followed the instructions in Step Four of the Initial Setup section,then you let EzSet handle this critical task for you, simply and auto-matically.However, if you prefer to make these adjustments manually, theAVR 145’s Channel Adjust menu allows you to do so, either using thesystem’s test tone or while playing source material. In addition, this isthe only method for adjusting the level of the subwoofer.You may use either the EzSet remote or a handheld SPL meter (avail-able at most electronics stores) set to the C-Weighting, Slow scale.1. Make sure all speakers have been connected correctly.2. Use the Speaker Size menu, or press the Speaker Setup Button onthe remote, to make sure the correct speaker size has been enteredfor each speaker in your system.3. Use the Speaker X-over menu to program the correct crossoversetting for each speaker in your system.4. Use the Delay Adjust menu, or press the Delay Button on theremote control, to enter the distance between each speaker andthe listening position.5. If you are using a handheld SPL meter with source material, such asa test disc or another audio selection, play it now and adjust theAVR’s master volume control until themeter measures 75dB.6. If you are using the EzSet remote, either set the master volume to–15dB, or you may play source material and press the SPL Buttononce. Adjust the volume until the LED turns green. If it’s amber, thevolume is too low; if it’s red, the volume is too high.7. 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 three 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 toadjust each channel so that the meter reads 75dB.c) Using the AVR 145 remote, press the SPL Button once so that theLED lights steadily. When it’s amber, the level is too low and should beraised. When the LED is red, the level is too high and should be low-ered. When the LED is green, the level is correct.A. Using the Remote Control With the Test ToneWhile sitting in the listening position, press the Test Button on theremote. The test tone will start playing at the front left channel. Aftera few seconds, it will move to the center channel, then the front rightchannel, surround right, surround left and finally the subwoofer, display-ing the channel name on the front of the receiver and in the semi-OSDdisplay, as well as the current level setting (varies between –10dB and+10dB). Press the ⁄/¤ Buttons to adjust the level setting, and thetone will remain at that channel until several seconds after your lastadjustment. When you have finished adjusting the levels, press the TestButton again to stop the tone. Measure the levels by ear, using an SPLmeter, or using the remote, as described above.B. Using the Front-Panel ControlsYou may adjust the levels by pressing the Channel Button on the frontpanel, and the FRONT L LEVEL message will appear. Use the ‹/›Buttons on the front panel to select the desired speaker channel toadjust, and press the Set Button when the desired channel is displayed.The current level for that channel will appear, and you may adjust itusing the ‹/› Buttons. Press the Set Button to return to the speakerchannel choices. This method is not recommended, as you will not beable to measure the channel levels at the listening position. In addition,this method requires that a source is playing.C. Using the Full-OSD MenuNext to EzSet, the full-OSD menu system offers the easiest and mostflexible manner of setting output levels. Press the OSD Button to displaythe Master Menu, and then navigate to the MANUAL SETUP line. Pressthe Set Button to display the Manual Setup menu, and then navigate tothe CHANNEL ADJUST line. Press the Set Button to display the ChannelAdjust menu.Figure 67 – Channel Adjust Menu ScreenAll of the speaker channels will appear at the top of the screen with theircurrent level settings. Any channels that have not been programmedusing the Speaker Size menu will display four dashes and will not beaccessible.CHANNEL RESET: If you wish to start by resetting all of the levels totheir factory defaults of 0dB, navigate to this line and change the settingto ON. The levels will be reset, and this setting will then revert to OFF.
