ADVANCED FUNCTIONS 4. There are several methods of adjusting the channel output levels, using either the test tone or source materials. In all cases, you may measure 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. A. Using the Remote Control With the Test Tone While sitting in the listening position, press the Test Button on the remote. The test tone will start playing at the front left channel. After a few seconds, it will move to the center channel, then the front right channel, surround right, surround back right, surround back left, surround left and finally the subwoofer, displaying the channel name on the front of the receiver and in the semi-OSD display, as well as the current level setting (varies between -10dB and +10dB). Press the ⁄/¤ Buttons to adjust the level setting, and the tone will remain at that channel until several seconds after your last adjustment. When you have finished adjusting the levels, press the Test Button again to stop the tone. Measure the levels by ear, or using an SPL meter, as described above. B. Using the Front-Panel Controls You may adjust the levels by pressing the Channel Button on the front panel, and the FRONT L LEVEL message will appear. Use the ‹/› Buttons on the front panel to select the desired speaker channel to adjust, and press the Set Button when the desired channel is displayed. The current level for that channel will appear, and you may adjust it using the ‹/› Buttons. Press the Set Button to return to the speaker channel choices. This method is not recommended, as you will not be able to measure the channel levels at the listening position. In addition, this method requires a source to be playing. C. Using the Full-OSD Menu Next to EzSet+, the full-OSD menu system offers the easiest and most flexible manner of setting output levels. Press the OSD Button to display the Master Menu, and then navigate to the MANUAL SETUP line. Press the Set Button to display the Manual Setup menu, and then navigate to the CHANNEL ADJUST line. Press the Set Button to display the Channel Adjust menu. See Figure 85. Figure 85 - Channel Adjust Menu Screen All of the speaker channels will appear at the top of the screen with their current level settings. Any channels that have not been programmed using the Speaker Size menu will display four dashes and will not be accessible. In addition, if you have selected a surround mode that does not utilize all speakers, such as Surround Off, you will see dashed lines next to the speakers that aren't needed for that mode. CHANNEL RESET: If you wish to start by resetting all of the levels to their factory defaults of 0dB, navigate to this line and change the setting to ON. The levels will be reset, and this setting will then revert to OFF. If you are using an external source to set your output levels, simply navigate to each channel and use the ⁄/¤ Buttons to adjust the level as desired. If you would like to set your levels using the AVR 245's internal test tone, you will need to adjust the TEST TONE SEQ and TEST TONE lines as follows. TEST TONE SEQ: When this setting reads AUTO, the test tone will automatically circulate to all channels, pausing for a few moments at each channel and then moving to the next channel several seconds later, as indicated by the blinking cursor. You may adjust the level for any channel when the test tone is paused there by using the ‹/› Buttons. You may also use the ⁄/¤ Buttons at any time to move the cursor to another line, and the test tone will follow the cursor. When this setting reads MANUAL, the test tone will not move to the next channel until you use the ⁄/¤ Buttons to move it. TEST TONE: This line determines whether the test tone is active. To begin the process of setting the levels, use the ‹/› Buttons to change the setting to ON. Any time you manually move the cursor out of the channel listings area of the screen, this setting will automatically change to OFF, stopping the test tone. NOTE: Setting the channel levels while one surround mode is active does not necessarily carry over to all other modes. We recommend that after you have set the levels satisfactorily in one mode, you note the results and change to other surround modes. For those modes that don't reflect your level settings, you may either copy the settings you obtained (as a short cut), or redo the procedure to determine the correct settings for those surround modes. Multiroom Operation The AVR 245 offers the benefits of multiroom operation, a rarity in a receiver this affordable. With the multiroom system in use, you may enjoy an exciting 5.1-channel home theater presentation in the main listening area, while others listen to the same materials or an entirely different presentation in another room. Although installation of a multiroom system is not complicated, it is often accomplished by running wires inside walls. We urge you to check your local building codes and comply with the requirements for in-wall wiring systems to prevent the possibility of a dangerous situation. If you have any questions about installing a multiroom system, we strongly recommend that you contact a professional custom installer in your area. 53
