11 The Advanced MCACC menu Precision Distance (SC-37 only) Before using this function, perform the Full Auto MCACC Setup procedure (see page 43). Performing the Full Auto MCACC procedure corrects the distance to a precision of 1/2 inch, but the Precision Distance function lets you adjust the distance to the speakers (their position) with a precision of under 1/2 inch. Here, rather than correct the numerical value of the distance, actually move the physical positions of the speakers to fine-adjust (the subwoofer cannot be adjusted). The input from the microphone is indicated on the screen. Fine-adjust the positions of the speakers so that the gauge reading is maximum. The detailed distance adjustments that were previously performed by skilled installers by ear can easily be performed watching the gauge on the monitor. Place the microphone in the same position as when the microphone was connected and the Full Auto MCACC operation was performed. 1 Select 'Precision Distance' from the Manual MCACC setup menu. 2 Fine-adjust the positions of the speakers in sequence, starting from the front right channel.1 Test pulses are output from the speaker for the selected channel and from one other speaker. Move the position of the selected speaker 1/2 inch towards or away from the microphone. Watch the screen when doing so, and fineadjust the positions of the speakers so that the gauge reading is maximum. Also, the channel serving as the standard differs according to the channel being adjusted. Do not move the speaker serving as the standard channel. The maximum gauge reading is 10.0. (If the reading stays under 10.0, adjust the speaker for the maximum value.) 3 When you're finished, press RETURN. You will return to the Manual MCACC setup menu. Checking MCACC Data At the procedure of Automatically conducting optimum sound tuning (Full Auto MCACC) on page 43, the procedure of Automatic MCACC (Expert) on page 104 or after fine-adjusting at Manual MCACC setup on page 106, you can check your calibrated settings using the GUI screen. The data can be transferred to a computer using a USB device to check it on the computer's screen as well. 1 Set the remote control to the receiver operation mode, then press HOME MENU. A Graphical User Interface (GUI) screen appears on your TV. Use and ENTER to navigate through the screens and select menu items. Press RETURN to confirm and exit the current menu. 2 Select 'MCACC Data Check' from the Home Menu. 3 Select the setting you want to check. • Speaker Setting - Used to check the settings of the speaker systems. See Speaker Setting on page 111 for more on this. • Channel Level - Used to check the output level of the different speakers. See Channel Level on page 111 for more on this. • Speaker Distance - Used to check the distance to the different speakers. See Speaker Distance on page 111 for more on this. • Standing Wave - Used to check the standing wave control filter settings. See Standing Wave on page 111 for more on this. • Acoustic Cal EQ - Used to check the calibration values of the listening environment's frequency response. See Acoustic Cal EQ on page 111 for more on this. • Group Delay (SC-37 only) - Used to check the speakers' group delay (both before and after calibration). See Group Delay (SC-37 only) on page 111 for more on this. • Output MCACC data - See Output MCACC data on page 112 for more on this. 110 En Note 1 • If the microphone is placed in a different position from when the Auto MCACC procedure was performed, it may not be possible to adjust properly. In this case, we recommend performing the procedure at Fine Speaker Distance on page 107 in the Auto MCACC custom measurements, then performing the adjustment described here without moving the microphone. • The adjustment here is for adjusting for an error of 1/2 inch or less (not adjustable with the Auto MCACC Setup). 0.0 may be displayed after distance correction with the Auto MCACC Setup, but even in this case this adjustment allows you to optimize the correction. Note that if the Auto MCACC Setup is performed after completing the fine-adjustment here, the correction precision will drop to about 1/2 inch. • Like with the Auto MCACC Setup, perform this adjustment in as quiet an environment as possible. 0.0 will be displayed if abrupt noise is input during the adjustment. • The distance for all the channels can only be made uniform even if the R (front right) channel is adjusted in the proper order. • Be very careful not to tip the speakers over when moving them. • The result of the adjustment performed here can be checked by listening to the test pulses output at the Precision Distance (SC-37 only) (the test pulses will be more centrally positioned between the speakers than before the adjustment was performed). Be careful not to change the distance values at this time.
