11 The MCACC PRO menu Making receiver settings from the MCACC PRO menu The MCACC (Multi Channel ACoustic Calibration) PRO system was developed in Pioneer's laboratories with the aim of making it possible for home users to perform adjustments of the same level as in a studio easily and with high precision. The acoustic characteristics of the listening environment are measured and the frequency response is calibrated accordingly to allow high precision, automatic analysis and optimal calibration of the sound field to bring it closer to a studio environment than ever before. Furthermore, while it was previously difficult to eliminate standing waves, this receiver is equipped with a standing wave control function using a unique process to perform acoustic analysis and reduce their influence. This section describes how to calibrate the sound field automatically and fine-adjust the sound field data manually. 1 Press u STANDBY/ON to switch on the receiver and your TV. Make sure that the TV's video input is set to this receiver. 2 Press MAIN RECEIVER to switch the remote control to the receiver operation mode, and then press HOME MENU. A Graphical User Interface (GUI) screen appears on your TV. Use i/j/k/l and ENTER to navigate through the screens and select menu items. Press RETURN to exit the current menu. ! Press HOME MENU at any time to exit the HOME MENU. 3 Select 'MCACC PRO' from the HOME MENU, then press ENTER. 4 Select the setting you want to adjust. ! Full Auto MCACC - See Automatically conducting optimum sound tuning (Full Auto MCACC) on page 47 for a quick and effective automatic surround setup. ! Auto MCACC - See Automatic MCACC (Expert) on page 87 for a more detailed MCACC setup. ! Manual MCACC - Fine-tunes your speaker settings and customizes the Acoustic Calibration EQ (see Manual MCACC setup on page 88 ). ! MCACC Data Check - This displays the MCACC PRO measurement results. Use it to check the MCACC memory. For details, see Checking MCACC Data on page 91 . ! Data Management - Use this to manage the data in the MCACC memory. For details, see Data Management on page 92 . ! Demo - No settings are saved and no errors occur. When the speakers are connected to this receiver, the test tone is output repeatedly. Press RETURN to cancel the test tone. Automatic MCACC (Expert) If your setup requires more detailed settings than those provided in Automatically conducting optimum sound tuning (Full Auto MCACC) on page 47 , you can customize your setup options below. You can calibrate your system differently for up to six different MCACC presets, which are useful if you have different listening positions depending on the type of source (for example, watching movies from a sofa, or playing a video game close to the TV). Important ! Make sure the microphone/speakers are not moved during the Auto MCACC Setup. ! The screen saver will automatically appear after five minutes of inactivity. CAUTION ! The test tones used in the Auto MCACC Setup are output at high volume. 1 Select 'Auto MCACC' from the MCACC PRO menu, then press ENTER. If the MCACC PRO screen is not displayed, refer to Making receiver settings from the MCACC PRO menu on page 87 . 2 Select the parameters you want to set. Use i/j to select the item, then use k/l to set. ! Auto MCACC - The default is ALL (recommended), but you can limit the system calibration to only one set- ting (to save time) if you want. - When data measurement is taken (after selecting ALL or Keep SP System), the reverb characteristics data (both before- and after-calibration) that this receiver had been storing will be overwritten. - When measurement is performed with other than SYMMETRY (after selecting ALL or Keep SP System), the reverberation characteristics after calibration cannot be predicted, so the graph for the characteristics after calibration ("After") cannot be displayed. If you will need to display the graph for the characteristics after calibration ("After"), take the measurement using the EQ Professional menu in the Manual MCACC setup (page 88 ). - The EQ Pro & S-Wave measurement is also taken when ALL or Keep SP System is selected. See Acoustic Calibration EQ Professional on page 90 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 73 . ! 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 ALIGN sets all speakers in accordance with the front speaker settings (no equalization is applied to the front left and right channels). 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. EQ of subwoofer is automatically set when in ALL CH ADJ mode. ! 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 sev- eral 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 ! Dolby Enabled Speaker (It can be set only when ALL and Speaker Setting are selected for Auto MCACC) - Select speakers that use Dolby Enabled Speaker (TMd). When Dolby Enabled Speaker is not used, select NO (page 24) . ! SP to ceiling (When setting to use the Dolby Enabled Speaker, using Auto MCACC, you can perform the settings when ALL, Keep SP System, and Channel Level & Speaker Distance are selected): Input the vertical distance from the speaker to the ceiling when using a Dolby Enabled Speaker (page 24 ). 87
