Audiocom® Description The SPS2000A is a versatile power supply that can be used in a variety of Audiocom® intercom system applications. It is ideal for applications where it is desirable to use a master station with a panel mic / speaker combination. The SPS2000A directly accepts any AC input power from 100 to 240 VAC, 50/60 Hz, and it can be configured to power two separate intercom channels or one large intercom channel with twice the intercom station capacity.
2. Combine / Isolate Switch: This recessed, pushbutton switch lets you combine the audio signals of the two channels to create a single audio channel where all users can intercommunicate. Or, you can isolate each channel to create two groups of completely independent users. 3. Channel Status Indicators and Reset Pushbutton: The indicators are green for normal operation and red when there is an overload or short circuit.
