PS-2001L Front and Rear Panel Features Combine/Isolate Switch: When in the Combine position, the unit will combine the audio signals of the two channels to create a single audio channel where all users can intercommunicate. When in the Isolate position, the unit will create two groups of completely independent users. Channel Status Indicators: The indicators are green for normal operation and red when there is an overload or short circuit. The circuitry in the unit will automatically reset when the overload or short circuit is located and fixed. Universal AC Power Input: The unit 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. BAL/UNBAL Selector Switch: This selector switch allows the user to configure the unit for use in either an Audicom® (BALANCED) or Clear-Com (UNBALANCED) system. Compatibility includes channel connector pinouts, channel power requirements, and call signaling requirements. The default setting for this switch is in the Audiocom® (BAL) position. 2. 4. 5. 4 ® SPS-2001 1 Combine Isolate 2 Volume 1 4 INPUT 1 CH 1 2 5 CH 2 3 SPEAKERS LINE LEVEL 1VRMS 100-240 VAC 60/50 HZ TELEX COMMUNICATIONS, INC. MADE IN USA INPUT 2 UNBAL BAL CLASS 2 WIRING 1. 5A 24VDC 6 FIGURE 2. 1. SPS-2001 Front and Rear Panel Features Speaker, Inputs, and Volume Control: Two audio inputs are provided. The inputs are combined internally and set 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 microphone and speaker instead of a headset.

[. . . ] Using two SPS-2001 Power Supplies also lets you independently monitor and adjust volume for both intercom channels without the need for a separate powered loudspeaker. In this application, the US-2000A should be set for binaural speaker output as described in the US2000A manual. 12 Power-Up Check 1. Specifications General Input Power Requirements 100 to 240 VAC, 50/60 Hz Plug in any DC wallpacks that are being using with individual intercom stations. NOTE: If you plug in DC wallpacks after applying power to the PS2001L or SPS-2001, you may get an overload indication. This is because the stations that are being powered by wallpacks will draw current from the units until their own DC wallpack supplies are connected. To correct the problem, plug in the DC wallpacks. 2. Current Draw 750mA maximum (SPS-2001) 700mA maximum (PS-2001L) Output Power (each channel) 24 ±1 VDC, 1 Amp per channel Dimensions Plug in the AC power cords for any connected PS2001L or SPS-2001 Power Supplies.
