7.3Multi 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.
