Operation
Call stations and wall control panels can only operate when connected to the DSP matrix
mixer and individual IDs have been set via the DIP switches on the units. Refer to Call Station
DIP switch settings, page 23 and Wall Control Panel DIP switch settings, page 24.
The multi channel DSP amplifier can operate both as a standalone amplifier or connected to
the DSP matrix mixer.
