Operations on the Receiver and Cable Connections (Continued)
2
On the receiver, select "Acoustic Cal EQ Professional" then "Reverb
Measurement" and measure the reverberation characteristics of your room.
(For details, see pages 92 and 79 of the receiver's Operating Instructions.)
Reverberation characteristics can also be measured with "Auto Pro.," but it takes longer than with
"Reverb Measurement" because all steps up to EQ Setup are done automatically.
Note
When you receive the data you have already measured with "Reverb Measurement" or "Auto Pro.," you
do not need to measure the data again in this step.
3
In the on-screen display, select "PC Output".
The message "Operate a PC" appears and the receiver enters transmission standby mode. It is ready
to send data to your PC.
This completes the preparations for sending the measurement data to your PC.
(To send the data, proceed to the next section Application Operations .)
