Configuration Switches

The BAL / UNBAL switch (located on the rear of the unit) is set to the Balanced (Audiocom) position when the unit is shipped from the factory. To set the switch to the Unbalanced (Clear-Com) mode, use a pointed object such as a pen to push in the switch.

The Combine / Isolate switch (located on the front of the unit) can be changed at any time by using a pointed object such as a pen to push in the switch. When the switch is in the Combine position, all users on both channels may intercommunicate. When the switch is set to the Isolate position, channels 1 and 2 cannot intercommunicate.

Intercom Channel and Program Connections

Channel Capacity: When connecting intercom stations to the PS-2001L or SPS-2001, determine the total current for all stations on each channel. The total per channel should not exceed 2A. If you exceed this limit, an overload indication will be provided and the output of the power supply will be turned off. Once the overload is corrected, the overload indication will disappear and the power supply output will be turned on. Note that if you are using DC wallpacks with some intercom stations, you do not need to add the current consumption of those stations to the total current.

Audiocom Connections: Intercom Cable wiring details are shown in Figure 3. Speaker interconnection cables (SPS-2001 only) are standard RCA phono types. For program input cable wiring, refer to your master intercom station user manual. Some typical intercom applications are shown in Figures 4 through 8.

Clear-Com Applications: Refer to your Clear-Com system documentation for intercom cable wiring and connection details.

Desktop or Rackmount Installation

For desktop use, install the four supplied rubber feet to the bottom of the unit. Do not obstruct the cooling vents when using the unit on a desktop.

For rackmounting, use an optional Audiocom Rackmount Kit. Several kits are available to meet the requirements of your particular system. Follow the assembly instructions supplied with the rackmount kit.
