Introduction
Introduction
Thank you for purchasing the Audiocom ES4000A Intercom Expansion Station. We hope the many design features of this product will satisfy your intercommunication requirements for many years to come. To get the most out of the ES4000A, please take a few moments to look through this booklet before using the Intercom Expansion Station for the first time.
Description
The ES4000A is an Expansion Station for the US2002 User Station. It interfaces 4 additional intercom channels to the
US2002, and it provides talk, listen and call buttons for the 4 additional channels. There are also 4 additional program inputs on the back of the ES4000A, 1 for each added channel. Up to 4 ES4000A Expansion Stations may be connected to the US2002 to add up to 16 channels (18 channels total). The ES4000A typically utilizes the US2002 microphone and speaker (or microphone headset) for communication with the added channels. The ES4000A also has individual speaker outputs for independent monitoring of one or more of the 4 channels, if desired.
The US2002/ES4000A combination can be used as a simple, multi-channel intercom user station. In this configuration, the program inputs (and possibly the PA output of the US2002) are most likely not used, and the station operator has only talk, listen and call capability. It is also possible that advanced features of the US2002, such as Mic Kill Send, might be turned OFF.
Alternatively, the US2002 / ES4000A can be used as a master station. In this application, one or more program inputs and the
PA output may be connected, and the program signals to the intercom channels can be turned ON or OFF from the US2002.
Additionally, the Mic Kill Send feature can be enabled, and microphones on any channels may then be turned OFF from the
US2002.

IMPORTANT: The Local Power Jack only provides power to the ES4000A, it cannot be used to power the intercom system.
The EXP IN connector receives the microphone audio signal from the US2002, and it sends the monaural mix of the four ES4000A channels to the US2002 speaker or headset. The EXP OUT connector connects to the EXP IN connector of an additional ES4000A. Up to four (4) ES4000A Expansion Stations may be daisy chained with the
EXP IN and EXP OUT connectors. An EXP IN/OUT cable is supplied with each ES4000A.
Usually, the listen mix of all four (4) ES4000A channels is sent to the US2002 speaker or headset via the EXP IN connector. Alternatively speakers may be connected to one or more of the speaker outputs of the ES4000A.
This selector switch sets the ES4000A for compatibility with either Audiocom or Clear-Com channel connector pin-outs, channel power requirements, and call signaling requirements.
Each intercom channel has its own program input and level adjustment trimmer. For each program input, there is an internal jumper which routes the program either to the intercom channel only, or to both the intercom channel and the US2002 headset or speaker (default setting). Additionally, the program signal to the intercom channel may be turned ON or OFF via the US2002 front panel programming. There is also an intercom program interrupt DIP switch which selects either automatic program interrupt when the station operator activates a channel’s talk key, or no program interrupt during talk. The ES4000A program inputs connector may be broken out to common 3-pin
XLR audio cable using an option XP-4PGM Breakout Panel.
This connector provides the intercom channel audio input/output connects, as well as operating power when the
ES4000A is being powered from the intercom channels. Depending on the application, this connector can connect to either a PS4001 Power Supply, or to an XP-ES4000 Breakout Panel. Examples of both connections are provided in the wiring diagrams which follow. A channel output cable is supplied with each ES4000A

Configuration Pre-check
Before making connections, read the configuration notes that follow, and make sure that all switches and jumpers are properly
switches and jumpers require internal access. If access is required, remove one screw from the top cover and 3 screws from each side.
DIP Switches
Program Interrupt DIP Switches
Each Intercom channel has a dedicated program input. These can be used to feed background music, mix-minus audio (for broadcasting usage) etc. to the intercom channels. If external program sources will be connected to the ES4000A, you have a choice of whether or not you want the program audio to interrupt (shut off) on the intercom channel while the US2002/
ES4000A station operator is talking.

Configuration.
The SPS-2001 provides power for channels 1 and 2, and also provides the listening speaker for all 10 channels. A microphone must be connected to the US2002 for talk on the 10 channels. Each PS4001 provides power for 4 intercom channels and also interfaces with an ES4000A to the intercom channels. The XP-USPG interfaces 2 external program inputs to the US2002, and also interfaces the US2002 to an external PA system. Each XP-4PGM interfaces 4 external program sources to an ES4000A.
Connections and further details for this configuration are shown in Figure 6.
NOTE: An additional rack mount space is shown between the two PS4000 power supplies. This may be required to prevent power supply overheating when the ambient air temperature is high.

Installation
FIGURE 5.
Typical Rack Mount Configuration for a 6-Channel Master Speaker Station with Maximum Power Supply.
Each channel has a separate power supply, and the SPS-2001 on channel 1 also provides the listening speaker for all 6 channels. A microphone must be connected to the US2002 for talk on the 6 channels. The XP-USPG interfaces with two (2) external program inputs to the US2002, and also interfaces the US2002 to an external PA system. The XP-4PGM interfacesfour (4) external program sources to the ES4000A. The XP-ES4000 interfaces four (4) of the PS2001L power supplies to the four (4) channels of the ES4000A. The connection between the US2002 and the ES4000A, as well as the
shown in Figure 7. the power supply connections for the ES40000A are shown in Figure .

Connection Notes
• Typical connections for the US2002, ES4000A and various power supplies are shown starting with Figure 6.
Select the configuration which most closely matches your intended usage.
• The US2002 and ES4000A normally draw operating power from the intercom channel power supplies (SPS2001,
PS2001L, etc.). Alternatively, you can use option PS-L Wall-pack Power Supplies. If you are using PS-L Wallpacks, connect them to the 12-15 VDC jacks on the back panels of the US2002 and ES4000A. When PS-L Wallpacks are used, the US2002 / ES4000A will not draw power from the intercom channel power supplies, leaving more power for belt packs.
IMPORTANT: The PS-L power supply only provides power for the station that it is connected to. You cannot use the PS-L to power the intercom channels!
• Never connect more than 1 SPS2001 PS2001L, or PS4001 Power Supply to the same intercom channel. This will cause poor audio quality and increased noise. Typically, all power supplies are located at a central location, such as a central master station. This lets the central master station operator turn off the intercom system when it is not being used.
• Termination Plugs: The ES4000A is supplied with 2 termination plugs for special applications where 1 or more
plugs. If all of your incoming channels will be powered from an SPS2001, PS2001L, or PS4001 power supply, the termination plugs are not needed.
13
Installation
FIGURE 6.
Central Master Station with simple power supply configuration.
This 10-channel provides all of the channel power and program input connections for the intercom system. This configuration should only be used at one point in the intercom system. It is ideal for smaller intercom systems with fewer remote intercom stations. For optional power configurations that permit more stations, see Figures 7 through 10.
NOTE: The SPS2001 power supply includes a speaker and is typically used for intercom listening, with a gooseneck microphone connected to the US2002 for talk-back. Alternatively, a headset with a microphone may be used. In this case, no speaker is needed, and a PS2001L power supply may therefore be used in place of the SPS2001.

System using the termination plugs supplied with the ES4000A for mixed wet- and dryline operation.
In this example, channels 5 and 6 are powered from a PS2000L Power Supply (wet lines), while channels 3 and 4 are operated without power (dry lines). Any remote station connected to channel 3 or 4 must supply its own power. For example, a US2002 that is powered by a PS-L Power Supply could be connected to channels 3 and 4. The advantage of dry-line operation is that intercom stations may be operated over a much greater distance.
