Note
1If the Reverb View procedure is performed after the Automatically setting up for surround sound (Auto MCACC) on
page 37 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.
