[. . . ] Using a computer provides cleaner, more easily readable graphs. The application can also be used to display the measurement values stored in the receiver's MCACC memory. Requirements for using the application on your PC · The computer must be a PC functioning with one of the following operating systems: Microsoft® Windows® Vista Home Basic/Home Premium/Ultimate SP1 or Windows® XP Professional/Home Edition SP3. · The monitor must have a display resolution of 800 x 600 dots (SVGA) or greater. · The computer must be equipped with a USB port (a separate USB device is required to transfer measurement data from the receiver to the computer). Microsoft®, Windows®Vista and Windows®XP are either registered trademarks or trademarks of Microsoft Corporation in the United States and/or other countries. Main features of the application 1.

Each Ch: All the channels are displayed individually. The "Each Ch" display type is set when EQ calibration is performed with the reverberation type set to "ALL CH ADJ". Pair Ch: Composite reverb characteristics for the left and right pairs of the "Front", "Surround" and "Surr Back" channels are displayed. The "Pair Ch" display type is set when EQ calibration is performed with the reverberation type set to "SYMMETRY" or "FRONT ALIGN". Displays 3D graphs with rotating. a Demo a.

However, for the characteristics of the sound reaching the ear directly within about 40 ms, there is enough volume that there is no real need to boost the high frequencies, so with equalization using the conventional MCACC EQ calibration the high frequencies sometimes sounded too strong. Therefore, the Acoustic Cal EQ may result in a room where high frequencies sound shrill. In cases like this, setting the time period for Advanced EQ Setup to 30 to 50 msec (the blue area in Figure 2) to adjust for sounds coming directly from the speakers can flatten the frequency response for direct sounds (including initial reflections) and give a better-balanced sound field.

However, the sense of placement and movement of the acoustic image and the unity of the sound from the different speakers is influenced not by the reverberations but by the direct sound from the speakers (including the early reflected sound). In cases like this, you should use Advanced EQ Setup and set the time period to 30 to 50 msec (the blue area in Figure 3). This allows the characteristics of direct sounds to be balanced for each channel, giving an ideal sound field with good acoustic positioning and movement. Figure 3 Level (dB) Time period point to be selected Time (in ms) Front left channel Front right channel Pattern 3: Similar reverb characteristics for high and low frequencies and all channels As shown in Figure 4, when the reverb characteristics for all channels are similar across all frequencies, your sound experience will probably not be adversely affected by reverberation. We recommend calibrating with a time of about 60 to 80 [ms] (green part of Figure 4) specified at Advanced EQ Setup. This produces a total calibration for both direct sounds and reverberations, resulting in an ideal sound field. Figure 4 Level (dB) Time period point to be selected Front left low frequencies Front right low frequencies Front left high frequencies Front right high frequencies Time (in ms) Note · If you are not sure which time period to specify in Advanced EQ Setup, start by trying 30 to 50 msec. If the graphs show an unusual reverb curve for a specific frequency, the cause may be some accidental variation. Instead of selecting 30 to 50 msec, try another time period. · Another good method is to try various time periods in Advanced EQ Setup and select the one which sounds the best.
