10 The Advanced MCACC menu 2 Select the parameters you want to set. Use / to select the item, then use / to set. • Auto MCACC - The default is ALL (recommended), but you can limit the system calibration to only one setting (to save time) if you want.1 • EQ Type (only available when the Auto MCACC Menu above is EQ Pro & S-Wave) - This determines how the frequency balance is adjusted. After a single calibration is performed, each of the following three correction curves can be stored separately in the MCACC memory. SYMMETRY implements symmetric correction for each pair of left and right speakers to flatten the frequency-amplitude characteristics. ALL CH ADJ is a 'flat' setting where all the speakers are set individually so no special weighting is given to any one channel. FRONT ALIGN2 sets all speakers in accordance with the front speaker settings (no equalization is applied to the front left and right channels). • THX Speaker (only available when the Auto MCACC Menu above is ALL or Speaker Setting) - Select YES if you are using THX speakers (set all speakers to SMALL), otherwise leave it set to NO. • STAND.WAVE Multi-Point (only available when the Auto MCACC Menu above is EQ Pro & S-Wave) - In addition to measurements at the listening position, you can use two more reference points for which test tones will be analyzed for standing waves. This is useful if you want to get a balanced 'flat' calibration for several seating positions in your listening area. Place the microphone at the reference point indicated on-screen and note that the last microphone placement will be at your main listening position: 2nd reference point 1 3rd reference point 2 3 Main listening position 3 Connect the microphone to the MCACC SETUP MIC jack on the front panel. Make sure there are no obstacles between the speakers and the microphone. CONTROL ON / OFF MASTER VOLUME MCACC SETUP MIC iPod iPhone USB VIDEO CAMERA HDMI 5 Microphone Tripod If you have a tripod, use it to place the microphone so that it's about ear level at your normal listening position. If you do not have a tripod, use some other object to install the microphone.3 4 When you're finished setting the options, select START then press ENTER. 5 Follow the instructions on-screen. 6 Wait for the Auto MCACC Setup to finish outputting test tones. A progress report is displayed on-screen while the receiver outputs test tones to determine the speakers present in your setup. Try to be as quiet as possible while it's doing this.4 • With error messages (such as Too much ambient noise! or Check microphone) select RETRY after checking for ambient noise (see Problems when using the Auto MCACC Setup on page 37) and verifying the mic connection. If there doesn't seem to be a problem, you can simply select GO NEXT and continue. 7 If necessary, confirm the speaker configuration in the GUI screen. The configuration shown on-screen should reflect the actual speakers you have. Note 1 • When data measurement is taken (after selecting ALL or Keep SP System), the reverb characteristics data (both before- and aftercalibration) that this receiver had been storing will be overwritten. If you want to save the reverb characteristics data before measuring, connect a USB memory device to this receiver and transfer the data. • When measurement is taken of data other than SYMMETRY (after selecting ALL or Keep SP System), the data are not measured after the correction. If you will need to measure after correction data, take the measurement using the EQ Professional menu in the Manual MCACC setup (page 71). • The EQ Pro & S-Wave measurement is also taken when Keep SP System or EQ Pro & S-Wave is selected. See Acoustic Calibration EQ Professional on page 73 for more on this. • Either effect of Acoustic Calibration EQ Professional and Standing Wave can be switched on and off in the respective MCACC preset. For details, see Setting the Audio options on page 55. 2 If you selected ALL or Keep SP System as your Auto MCACC menu, you can specify the MCACC preset where you want to save the SYMMETRY, ALL CH ADJ and FRONT ALIGN settings. 3 It may not be possible to measure correctly if the microphone is placed on a table, sofa, etc. 4 Do not adjust the volume during the test tones. This may result in incorrect speaker settings. 70 En
