Setting Acoustic Calibration EQ Professional according to your room characteristics

Using the manual setup, you can set the time period at which the frequency response is analyzed, pinpointing the time that is best for system calibration with your particular room characteristics.

The graph below shows the difference between conventional acoustic calibration and professional calibration (the gray circle indicates the point where the microphone captures sound during frequency analysis).

If your room isn’t affected by the factors above, it is often not necessary to make a 30~50ms setting. Later time settings may provide a more detailed sound experience with your speaker system. It is best to try and see what works best for your particular room.

Note that changing the room (for example, moving

furniture or paintings) will affect the calibration results. In such cases, you should recalibrate your system.

As soon as audio is output from your speaker system, it is influenced by room characteristics, such as walls, furniture, and the dimensions of the room. The sooner the frequency analysis, the less it is influenced by the room. We recommend an earlier time setting of 30~50ms to compensate for two major factors that will influence the sound of most rooms:

Reverberance of high vs. low frequencies – Depending on your room, you may find that lower frequencies seem overly reverberant compared to higher frequencies (i.e. your room sounds ‘boomy’). This may result in a skewed frequency analysis if the measurement is done too late.

Reverb characteristics for different channels – Reverb characteristics can be somewhat different for each channel. Since this difference increases as the sound is influenced by the various room characteristics, it is often better to capture a frequency analysis early on for smoother mixing of

Reverb Measurement – Use this to measure the reverb characteristics before and after calibration. (For graphical output using a PC, see Connecting a PC for Advanced MCACC output on page 34 to connect an RS-232C cable before selecting this option.)

Reverb View – You can check the reverb

measurements made for specified frequency ranges in each channel.1 This can also be used to compare the reverb characteristics before and after calibration.2

Note

1If the Reverb View procedure is performed after the Automatically setting up for surround sound (Auto MCACC) on page 39 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.

2The reverb characteristics after calibration can be displayed even after performing the Full Auto MCACC function (Automatically setting up for surround sound (Auto MCACC) on page 39). In this case, the display shows the predicted reverb characteristics after calibration. If the measurements are taken using the Reverb Measurement command (page 79) with the equalizer on, the actually measured reverb characteristics after calibration are displayed.
