Description
The PS-2001L and SPS-2001 are versatile power supplies that can be used in a variety of Audiocom® intercom
system applications. They both directly accept any AC input power from 100 to 240 VAC, 50/60 Hz and can be
configured to power two separate intercom channels or one large intercom channel with twice the intercom station
capacity. Additionally, the units can be configured for compatibility with Clear-Com* Intercom Systems. The units
may be rack mounted or used on a desktop. For rack mounting, optional hardware is required. For desktop use, four
non-marring rubber feet are supplied. The SPS-2001 also provides a speaker with two mixed inputs making it ideal
for situations calling for a master station with a microphone / speaker combination.

Combine / Isolate Switch: When in the Combine position, the unit will combine the audio signals of the two
1.
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
2.
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
4.
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
5.
Audiocom® (BALANCED) or Clear-Com (UNBALANCED) system. Compatibility includes channel connector
pin-outs, channel power requirements, and call signaling requirements. The default setting for this switch is in the
Audiocom® (BAL) position.
