Bosch PLENA matrix - Multi Channel DSP Amplifier Settings

Multi Channel DSP Amplifier settings
The multi channel DSP amplifier does not require an ID to be connected to the DSP matrix
mixer. Amplifier settings that are configured by DIP switches are; input sensitivity and bridging
channels together. The DSP features are only able to be configured, after you have connected
to the unit using the PC software GUI. Refer to; Multi Channel DSP Amplifier PC GUI, page
28).
Some amplifier settings are configured by DIP switches; such as, the input sensitivity and
when bridging channels together.
