10 The Advanced MCACC menu • Type A: Reverberance of high vs. low frequencies Level Low frequencies High frequencies Acoustic Cal. EQ Pro calibration range Conventional MCACC EQ calibration range 0 80 160 Time (in msec) • Type B: Reverb characteristics for different channels Level Front L Front R Acoustic Cal. EQ Pro calibration range Conventional MCACC EQ calibration range 0 80 160 Time (in msec) If the pattern is as shown above, select the 3050ms setting. If not, this setting is not necessary. Using Acoustic Calibration EQ Professional 1 Select 'EQ Professional', then press ENTER. 2 Select an option and press ENTER. • Reverb Measurement - Use this to measure the reverb characteristics of your room. • Reverb View - You can check the reverb measurements made for specified frequency ranges in each channel.1 • Advanced EQ Setup - Use this to select the time period that will be used for frequency adjustment and calibration, based on the reverb measurement of your listening area. Note that customizing system calibration using this setup will alter the settings you made in Automatically conducting optimum sound tuning (Auto MCACC on page 41 or Automatic MCACC (Expert) on page 91 and is not necessary if you're satisfied with these settings. 3 If you selected 'Reverb Measurement', select EQ ON or OFF, and then START. The following options determine how the reverb characteristics of your listening area are displayed in Reverb View: • EQ OFF - You will see the reverb characteristics of your listening area without the equalization performed by this receiver (before calibration). Note 1 If the Reverb View procedure is performed after the Automatically conducting optimum sound tuning (Auto MCACC on page 41 or Reverb Measurement operation, depending on the standing wave control setting, differences may appear on the reverb graph. With the Auto MCACC function, the reverberations are measured with the standing waves controlled, so the reverb characteristics graph shows the characteristics with the effect of the standing waves eliminated. By contrast, the Reverb Measurement function measures the reverberations without controlling the standing waves, so the graph indicates the reverb characteristics including the effect of the standing waves. If you wish to check the reverb characteristics of the room itself (with the standing waves as such), we recommend using the Reverb Measurement function. 98 En
