3.1 Volume Control
In DUAL and PARALLEL mode, the level controls CH A and CH B on the power amp’s front panel are used
to control the amplification of the corresponding channel. Turning the control to the right increases and
turning it to the left decreases the volume. In BRIDGED mode operation, the output volume of the power
amp is only controlled by the CH A level control. Any changes in the setting of the CH B level control are
ignored.
With an installed remote control module, the level controls CH A and CH B may be deactivated, i.e.
controlling the power amp’s amplification is only possible via IRIS-Net™. The Level Controls Off !
indicator on the graphical LC display signals that the controls are deactivated.
3.2 Graphical LC display
The graphical LC display provides detailed information about the operating status of the power amplifier.
Furthermore, it is possible to change several settings of the power amp and, if installed, of a remote control
module.
