7.2 Setting the operating range

Before setting the operating range, you must have figures sho-
wing the volume range at the location of application.
Indoors, the volume usually fluctuates between 50 and 80 dB,
80 dB being very loud.
Outdoors, considerably higher values of between 60 and 90 dB
are attained. On a busy street, noise levels reach on average
between 75 and 85 dB.
Set the min controller so that 2-3 LEDs light up on the gain LED
chain. If it is quiet during the setup, only one or no LEDs may
light up. Leave the min controller set to 50 dB (turned fully to
the left).
Adjust the sound to the desired level using the volume ch1 / ch2
volume control.
You can now use the gain max / min switch to check how quiet
and how loud the sound goes following the control process.
For precision adjustments, you should switch on e.g. a radio to
simulate different levels of ambient noise.
If the range seems too large or too small, you have 2 options:
1. If the volume is not loud or is not to be increased, change
the ratio of the readjustment control using the ratio control-
ler.
2. If the surrounding noise level is high and no more readjust-
ments are to be made, reduce the control range using the
range controller.

7.3 Setting the time constants

Normally, the fast control time of time = 1 sec is too fast. In this
case, adjustments in volume are too sudden.
Turn the time controller clockwise, until you can no longer hear
the volume being readjusted. Values between 10 and 100
seconds give good results.

7.4 Setting the AWU automatic function

If the volume of the signal increases even when the ambient
noise remains constant, turn the AWU controller to the right
until the AWU active LED lights up red. The control switches off
when the sounds become loud. Readjustments are made when
the sounds are quieter.
With the AWU controller, the AVM•1 even functions with loud
foreground music or speech.
What is more, the system does not build-up if the material is
very dynamic.
The AWU controller should always be tested with high volumes
are involved, even if they are not used during normal operation.
Correct setting is also good protection against incorrect operati-
on.
