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
