Before continuing, make sure you have completed step 2
in
Checking MCACC Data on page 115. The data
measured with the Advanced MCACC function is
transmitted to the connected computer. 1 The 3D graphs

complete, then you will be able to analyze the output on
your computer. The various parameters, the reverb
characteristics and group delay characteristics data
used for display on the computer are not cleared when
the power is turned off. If the reverb characteristics are
re-measured, however, the data is overwritten. 2

1 To transmit data, the receiver and computer must be connected using an RS-232C cable and a special application must be installed on the
computer. See Connecting a PC for Advanced MCACC output on page 40 for more on this.
2 Only one set of reverb characteristics is stored on the receiver. If you wish to compare several different measurement results, transmit the
data to the computer each time reverb measurements are taken.
Start the MCACC application on your PC.
