7. Press the Play button to start the test noise for that channel.
Pressing the Play button outputs test noise on that channel and displays the sound level. (Press
the Play button again to stop the test noise.)
8. Read the level in dB and make sure that each channel is measured at approximately -6 to -22 dB
(normal listening levels), which corresponds to the green indicator. If the indicator is red, you
need to adjust the recording level. Then press the Play button again to stop the playback on the
channel. Do this for all channels that are being measured. See Figure 10.
In a large venue it may not always be possible to use the same recording level on all speakers.
In that case, select a recording level which works for the first used channel. Then, if the level
is too low or too high during recording of other channels, the software will allow you to
change the recording level during measurements.
