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 nor-

mal operation and red when there is an overload or short circuit. The Reset push-

button restores normal operation after the short-circuit or overload has been

located and fixed.

4.

Universal AC Power Input: The SPS2000A accepts any input power in the range

of 100-240 VAC, 50/60 Hz.

5.

Intercom Channel Connectors: When the Combine / Isolate switch is set to the

Isolate position, each channel connector is powered separately and has com-

pletely separate intercom audio. When the Combine / Isolate switch is set to the

Combine position, each channel is still powered separately, but the audio signals

are combined so that all users on both channels can intercommunicate.

6.

Audiocom / Clear-Com Selector Switch (Figure

2

): This selector switch sets the

SPS2000A for compatibility with either Audiocom (BALANCED) or Clear-

Com (UNBALANCED). Compatibility includes channel connector pin-outs,

channel power requirements, and call signaling requirements. The SPS2000A is

shipped with this switch in the Audiocom position.
