Wall Control Panel DIP switch settings The wall control panel is designed to control either the back ground music inputs or the mic./ line inputs in one specific zone. As such each wall control panel requires an ID to let the DSP matrix mixer know which unit (or zone) is requesting a change in source or volume. This is done via DIP IDs switches to [...]

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[...]

DSP matrix mixer PC GUI All audio set up configurations for the DSP matrix mixer are done via the PC software GUI.
