11 The MCACC PRO menu 1 Select 'Manual MCACC' from the MCACC PRO menu. See Making receiver settings from the MCACC PRO menu on page 87 if you're not already at this screen. 2 Select the setting you want to adjust. If you're doing this for the first time, you might want to make these settings in order. ! Fine Channel Level - Make fine adjustments to the overall balance of your speaker system (see Fine Channel Level on page 89 ). ! Fine SP Distance - Make precise delay settings for your speaker system (see Fine Speaker Distance on page 89 ). ! Standing Wave - Control overly resonant low frequencies in your listening room (see Standing Wave on page 89 ). The last two settings are specifically for customizing the parameters explained in Acoustic Calibration EQ Adjust on page 90 : ! EQ Adjust - Manually adjust the frequency balance of your speaker system while listening to test tones (see Acoustic Calibration EQ Adjust on page 90 ). ! EQ Professional - Calibrate your system based on the direct sound coming from the speakers and make detailed settings according to your room's reverb characteristics (see Acoustic Calibration EQ Professional on page 90 ). 3 Select each channel in turn and adjust the distance as necessary. Use k/l to adjust the delay of the speaker you selected to match the reference speaker. (If Dolby Enabled Speaker is used, the distance reached by the speaker sound reflected at the ceiling is displayed (page 24 ).) Listen to the reference speaker and use it to measure the target channel. From the listening position, face the two speakers with your arms outstretched pointing at each speaker. Try to make the two tones sound as if they are arriving simultaneously at a position slightly in front of you and between your arm span. ! If you can't seem to achieve this by adjusting the distance setting, you may need to change the angle of your speakers very slightly. ! The subwoofer's test tone differs in tone from other channels. Adjust so that the sound of the subwoofer can be heard distinctly. Note that when adjusting the subwoofer, depending on the low frequency response of your speaker, it may be difficult to hear the change even when the setting is increased or decreased or when the position of the speaker is changed. Note that it may be difficult to compare this tone with the other speak- ers in your setup (depending on the low frequency response of the reference speaker). Fine Channel Level ! Default setting: 0.0dB (all channels) You can achieve better surround sound by properly adjusting the overall balance of your speaker system. You can adjust the Channel Level of each speaker in 0.5 dB increments. The following setting can help you make detailed adjustments that you may not achieve using the Manual speaker setup on page 94. 1 Select 'Fine Channel Level' from the Manual MCACC setup menu. The volume increases to the 0.0 dB reference level. 2 Adjust the level of the left channel. This will be the reference speaker level, so you may want to keep the level around 0.0dB so that you'll have plenty of room to adjust the other speaker levels. ! After pressing ENTER, test tones will be output. 3 Select each channel in turn and adjust the levels (+/-12.0 dB) as necessary. Use k/l to adjust the volume of the speaker you selected to match the reference speaker. When it sounds like both tones are the same volume, press j to confirm and continue to the next channel. ! For comparison purposes, the reference speaker will change depending on which speaker you select. ! If you want to go back and adjust a channel, simply use i/j to select it. 4 When you're finished, press RETURN. You will return to the Manual MCACC setup menu. Fine Speaker Distance ! Default setting: 10'00'' (all speakers) For proper sound depth and separation with your system, it is necessary to add a slight bit of delay to some speakers so that all sounds will arrive at the listening position at the same time. You can adjust the distance of each speaker in half inch increments. The following setting can help you make detailed adjustments that you may not achieve using the Manual speaker setup on page 94 . 1 Select 'Fine SP Distance' from the Manual MCACC setup menu. 2 Adjust the distance of the left channel from the listening position. When setting the Dolby Enabled Speaker, input the vertical distance from the speaker to the ceiling and the distance to each Dolby Enabled Speaker from the listening/viewing position (page 24) . When it sounds like the delay settings are matched up, press j to confirm and continue to the next channel. ! For comparison purposes, the reference speaker will change depending on which speaker you select. ! If you want to go back and adjust a channel, simply use i/j to select it. 4 When you're finished, press RETURN. You will return to the Manual MCACC setup menu. Standing Wave ! Default setting: ON/ATT 0.0dB (all filters) Acoustic standing waves occur when, under certain conditions, sound waves from your speaker system resonate mutually with sound waves reflected off the walls in your listening area. This can have a negative effect on the overall sound, especially at certain lower frequencies. Depending on speaker placement, your listening position, and ultimately the shape of your room, it results in an overly resonant ('boomy') sound. The Standing Wave Control uses filters to reduce the effect of overly resonant sounds in your listening area. During playback of a source, you can customize the filters used for Standing Wave Control for each of your MCACC presets. ! Standing Wave control filter settings cannot be changed during playback of sources using the HDMI connection. 1 Select 'Standing Wave' from the Manual MCACC setup menu. 2 Adjust the parameters for the Standing Wave Control. ! Filter Channel - Select the channel to which you will apply the filter(s): MAIN (all except center channel and subwoofer), Center or SW (subwoofer). ! TRIM (only available when the filter channel above is SW) - Adjust the subwoofer channel level (to compensate for the difference in output post-filter). ! Freq / Q / ATT - These are the filter parameters where Freq represents the frequency you will be targeting and Q is the bandwidth (the higher the Q, the narrower the bandwidth, or range) of the attenuation (ATT, the amount of reduction to the targeted frequency). 3 When you're finished, press RETURN. You will return to the Manual MCACC setup menu. 89
