In the factory setting, this volume controls are disabled.
In the web interface you can enable this volume control. (see page 41)
It is possible that an external control element (web interface, remote, GPI) sets the gain of
a channel at a lower level than what the gain control's position indicates. In this case, you
must turn down the potentiometer until the current value of the control is the same as the
current gain. When you have done this, you can once again change the volume using the
gain control.
If you control the volume using the GPI interface, you must follow the same rules as with the
gain controls on the front panel.
To adjust the volume on the front panel, the gain controls must not be locked. (See page

5.5.3.5 Delay
For each channel you have a delay for time alignment of a maximum of 2000 milliseconds.
Calculate the delay with the following formula:
t = d / c
t = time in seconds
d = distance in meters
c = speed of sound in m / s
