English AVR Advanced Functions, continued Crossover After you return to the Manual Setup menu, navigate to the Crossover line and press the OK button to display the Crossover menu. Crossover Left/Right Center Surround Sub 100Hz 100Hz 100Hz 10inch Refer to Table A5 for each speaker's crossover frequency. NOTE: The AVR will let you adjust settings only for those speaker groups you set to On in the Number of Speakers menu. For each speaker group, select one of these eight crossover frequencies: LARGE, 40Hz, 60Hz, 80Hz, 100Hz, 120Hz, 150Hz or 200Hz. If the speaker's crossover frequency is below 40Hz, select the first option, LARGE. This setting doesn't refer to the speaker's physical size but to its frequency response, which is also called "full range." Specify the size of the subwoofer's transducer as 8, 10, 12 or 15 inches. The AVR always sets the subwoofer crossover to 100Hz but uses the transducer size for equalization. Write down the settings in Table A5 in the Appendix. When you have finished entering the settings, press the remote's Back button. Sub Mode After you return to the Manual Setup menu, navigate to the Sub Mode line and press the OK button to display the Sub Mode menu. This setting depends upon the Crossover setting you selected for the left and right speakers. • If you set the Left/Right speakers to a numeric crossover frequency, the subwoofer setting will always be SUB. All low-frequency information will always be sent to the subwoofer. If you don't have a subwoofer, either upgrade to full-range front left and right speakers or add a subwoofer at the earliest opportunity. • If you set the front speakers to LARGE, select one of the three following settings for the subwoofer: L/R+LFE: This setting sends all low-frequency information to the subwoofer, including a) low-frequency information that is also played through the front left and right speakers and b) the special low-frequency effects (LFE) channel information. OFF: Select this setting when no subwoofer is in use. All low-frequency information will be sent to the front left and right speakers. LFE: This setting plays low-frequency information contained in the full-range program channels through the front left and right speakers, and directs only the LFE-channel information to the subwoofer. When you have finished entering the settings, press the remote's Back button. Set the Speaker Distances As described above in Step Two, when you measured the distances from each of your speakers to the listening position, your AVR provides an adjustment that compensates for the different distances so that the sound from each speaker will reach the listening position at the proper time. This process will improve the clarity and detail of the sound. After you return to the Manual Setup menu, navigate to the Distance line and press the OK button to display the Distance menu. Distance FL CEN FR SR SL Sub Delay Reset Unit A/V Sync Delay 3.0M 3.0M 3.0M 3.0M 3.0M 3.0M Off Meter 0mS Enter the distance from each speaker to the listening position that you measured in Step Two and recorded in Table A3 in the Appendix (see page 30). Select a speaker, then use the Left/Right buttons to change the measurement. You can enter distances between 0 and 30 feet (9m). The default distance for all speakers is 10 feet (3m). The default unit of measurement is meters. To change the unit to feet, scroll down to the Unit line and press the Left/Right buttons. When you have finished entering the settings, press the remote's Back button. Step Four - Setting Channel Output Levels Manually For a conventional stereo AVR, a simple balance control adjusts the stereo imaging by varying the relative loudness of the left and right channels. In a home theater system with up to five main channels plus a subwoofer, achieving proper imaging becomes both more critical and more complex. The goal is to ensure that each channel is heard at the listening position with equal loudness (when signals of equal loudness are played through them). Your AVR's EzSet/EQ calibration can handle this critical task for you simply and automatically. However, the AVR's Level Adjust menu allows you to calibrate the levels manually, either using the system's built-in test tone or while playing source material. After you return to the Manual Setup menu, navigate to the Level Adjust line and press the OK button to display the Level Adjust menu. Level Adjust FL CEN FR SR SL Sub Channel Reset Test Tone SEQ Test Tone 0dB 0dB 0dB 0dB 0dB 0dB Off Manual Off All of the system's speakers will appear with their current level settings. You can adjust each speaker's level between -10dB and +10dB in 1dB increments. While making adjustments, you can measure the channel levels in one of these ways: • P referably, use a handheld SPL meter set to C-weighting, slow scale. Adjust each speaker so that the meter reads 75dB when the AVR's built-in test noise is playing. • B y ear. Adjust the levels so that the test tone sounds equally loud to you when it plays through each speaker. 25
