Telex Communications, Inc. 2 Ch 2.0 Amp Switching Power Supply with Built-In Speaker SPS2001

Speaker Inputs and Volume Control Two audio inputs are provided. The inputs are combined internally and sent as a monaural signal to the internal speaker amplifier. The volume control adjusts the level to the front panel speaker. Typically, these inputs are used with the speaker outputs of a master station when the master station is set for use with a panel mic and speaker instead of a headset. Combine/Isolate Switch This recessed push-button 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. Channel Status Indicators And Reset Push-Button The indicators are green for normal 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. Universal AC Power Input The SPS-2001 accepts any input power in the range of 100- 240 VAC, 50/60 Hz. Intercom Channel Connectors When the Combine/Isolate switch is set to the Isolate position, each channel connector is powered separately and has completely 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. Telex Audiocom / Clear-Com Selector Switch This selector switch sets the SPS-2001 for compatibility with either Telex Audiocom (BALANCED) or Clear-Com (UNBALANCED). Compatibility includes channel connector pin-outs, channel power requirements, and call signaling requirements. The SPS-2001 is shipped with this switch in the Telex Audiocom position. Instantaneous Auto-Reset Instantaneous Auto Reset (IAR), the newest technology in performance and safety, which uses a revolutionary new circuitry that dynamically monitors line fault conditions. Then, when the fault is removed, automatically brings individual power supply channels up.
