Supervised Audio System Mother Board (SAMB-A)
The supervised audio system mother board (SAMB-A) provides all signal handling capabilities between the SADC and the amplifier
modules, terminal blocks for output wiring, and connectors for handling signals between the SADC and the digital voice module and
the SABC.
The SAMB-A is illustrated in Figure 24.
Up to four amplifier modules may be connected to the SAMB-A. The amplifier modules may be installed in any order in slots 1
through 4. Installing an amplifier module in slot 1 thru 4 will result in the module’s output appearing in the correspondingly
numbered terminal block (labeled “Zone 1” thru “Zone 4”). For example, when an amplifier module is installed in slot 1, the amplifier
module’s output appears at the terminal block labeled “Zone 1”.
Only one SADC may be connected to the SAMB-A. The SADC may only be installed in slot 5.
Up to four channels from a digital voice module may be connected to the SAMB-A. The digital voice module channels may be
connected in any order to connectors J8 through J11. The digital voice module channel connected to J8 will play through Zone 1; if
connected to J9, it will play through Zone 2; if connected to J10, it will play through Zone 3; if connected to J11, it will play through
Zone 4.
Connector J14 is the microphone input. J7 is the line out which should be connected to the DX-200’s auxiliary input (J7 should be
left unconnected in DX-100 configured systems). J12 is used to bring power to the digital voice module and monitor the digital voice
module’s status contact. J13 is used to monitor the SABC’s status.
