Description
The ES4000A is an Expansion Station for the US2000A User Station. It interfaces 4
additional intercom channels to the US2000A, and it provides talk, listen and call but-
tons 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 US2000A to add up to 16 channels (18 channels total). The
ES4000A typically utilizes the US2000A 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 US2000A / ES4000A combination can be used as a simple, multi-channel inter-
com user station. In this configuration, the program inputs (and possibly the P Aoutput
of the US2000A) 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 US2000A, such as
Mic Kill Send, might be turned off. Alternatively,the US2000A / 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 US2000A. Additionally, the Mic Kill Send feature can be en-
abled, and microphones on any channels may then be turned off from the US2000A.

Features
1.Intercom Talk Keys: Momentary or latching (hands-free) operation possible.
2.Call Keys: Used to call intercom channels and to indicate incoming calls.
3.Intercom Listen Keys: Momentary or latching operation possible.
4.Local Power Jack: The ES4000A can be powered from the intercom channels
via the CHANNEL 3-6 OUTPUTS connector (9). Alternatively, an optional
PS-L wall-pack accessory may be used to power the ES4000A from an AC out-
let. When power is sensed at the local power jack, the ES4000A automatically
disconnects from channel power. This means more channel power is available
for additional belt packs.
Important: The Local Power Jack only provides power to the ES4000A: it can-
☞
not be used to power the intercom system.
5.EXP IN and EXP OUT Connectors: The EXP IN connector receives the micro-
phone audio signal from the US2000A, and it sends the monaural mix of the
four ES4000A channels to the US2000A speaker or headset. The EXP OUT con-
nector connects to the EXP IN connector of an additional ES4000A. Up to 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.
6.SPEAKERS: Usually, the listen mix of all 4 ES4000A channels is sent to the
US2000A speaker or headset via the EXP IN connector. Alternatively, speakers
may be connected to one or more of the speaker outputs of the ES4000A.
7.BAL / UNBAL Switch: 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.
8.Program Inputs Connector and Trimmers: Each intercom channel has its own
program input and level adjust trimmer. For each program input, there is an inter-

nal jumper which routes the program either to the intercom channel only, or to
both the intercom channel and the US2000A headset or speaker (default setting).
Additionally, the program signal to the intercom channel may be turned on or
off via the US2000A front panel programming. There is also an internal 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 cables using an optional XP-4PGM Breakout Panel.
9.CHANNEL 3-6 OUTPUTS Connector: This connector provides the intercom channel audio input and output connections, 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 PS4000 Power Supply, or to an
XP-ES4000 Breakout Panel. Examples of both connections are providedinthewiring diagrams which follow. A channel output cable is supplied with each ES4000A.
10. Configuration Switches, Jumpers and Sidetone Controls (Figure 2

Audiocom Call Send and Receive DIP Switches
By default, all channels of the ES4000A can send and receive Audiocom call signals.
You can disable call send or call receive capability for selected channels if desired.
When the BAL / UNBAL switch on the back panel is set to the UNBAL position
☞
(for use with a Clear-Com Intercom System) the call send and call receive DIP
switches have no effect. Call send and call receive are always on for Clear-Com
usage.
Balanced/Unbalanced Switch (SW2)
This switch must be set to the balanced (BAL) position for use with an Audiocom
Intercom System. Set the switch to the unbalanced (UNBAL) position when using
the US2000A / ES4000A with a Clear-Com Intercom System.
Direct Program Listen Enable / Disable Jumpers
By default, each program input can be heard by intercom stations on the corresponding intercom channel. (This can be turned on or off for each program input via the
US2000A front panel programming. See "Turning the Program Inputs On and Off"
in the Operation section of the US2000A User Instructions.) Additionally, all program signals can be heard directly in the US2000A speaker or headset, and each program is output at the corresponding speaker jack on the back of the ES4000A. To
disable direct program listening for a program input, reset the appropriate jumper as
shown in Table 2. Locations of the jumpers are shown in Figure 2, page 6.

These trimmers are normally adjusted after all components are connected, and they
can be accessed through the bottom cover (Figure 15). Refer to the US2000A User
Manual for the sidetone adjustment procedure.
Mounting Configurations
The ES4000A can be used on a desktop, or it can be rack mounted. For desktop use,
install the 4 rubber feet supplied with the ES4000A. For rack mounting, use optional
Audiocom RMK Rack Mount Kits (Figure 3
). Many configurations are possible
when using the kits. Examples are shown in Figures 4 and 5.
When rack mounting components, you may not be able to access the sidetone
☞
trimmers after the components have been mounted. In this case, you can position
the components in the rack and make all required connections. Then, adjust the
sidetone trimmers before installing and tightening all rack mount screws.

Figure 4. Typical Rack Mount Configuration for a 10-Channel Master Speaker Station with Minimum Power Supply
Configuration. The SPS-2000A provides power for channels 1 and 2, and also provides the listening speaker for all 10 chan-
nels. A microphone must be connected to the US2000A for talk on the 10 channels. Each PS4000 provides power for 4 intercom channels and also interfaces an ES4000A to the intercom channels. The XP-USPG interfaces 2 external program inputs to
the US2000A, and also interfaces the US2000A 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
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.

Figure 5. Typical Rack Mount Configuration for a 6-Channel Master Speaker Station with Maximum Power Supply
Configuration. Each channel has a separate power supply, and the SPS-2000A on channel 1 also provides the listening
speaker for all 6 channels. A microphone must be connected to the US2000A for talk on the 6 channels. The XP-USPG
interfaces 2 external program inputs to the US2000A, and also interfaces the US2000A to an external PA system. The
XP-4PGM interfaces 4 external program sources to the ES4000A. The XP-ES4000 interfaces 4 of the PS2000L power supplies
to the 4 channels of the ES4000A. The connection between the US2000A and the ES4000A, as well as the connections of the
XP-USPG and XP-4PGM, are shown in Figure 6
power supply connections for the ES4000A are shown in Figure 9

Connection Notes
Typical connections for the US2000A, ES4000A and various power supplies are
•
shown starting with Figure 6, page 14. Select the configuration which most
closely matches your intended usage.
The US2000A and ES4000A normally draw operating power from the intercom
•
channel power supplies (SPS2000A, PS2000L, etc.). Alternatively, you can use
optional PS-L Wall-pack Power Supplies. If you are using PS-L Wall-packs,
connect them to the 12-15 VDC jacks on the back panels of the US2000A and
ES4000A. When PS-L Wall-packs are used, the US2000A / 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 a PS-L to power the intercom channels!
•Never connect more than 1 SPS2000A, PS2000L, or PS4000 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 channels are unpowered. Figures 12, page 20
and 13, page 21 show examples of how to use these plugs. If all of your intercom channels will be powered from an SPS2000A, PS2000L, or PS4000 power
supply, the termination plugs are not needed.
Note: For further information about the cable numbers, see page 22.

Figure 6. Central master station with simple power supply configuration. This
10-channel station 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 SPS2000A power supply includes a speaker and is typically
used for intercom listening, with a gooseneck microphone connected to the
US2000A for talk-back. Alternatively, a headset with a microphone may be used. In
this case, no speaker is needed, and a PS2000L power supply may therefore be
used in place of the SPS2000A.

Figure 11. Typical remote 10-channel master station or user station. This intercom station can have the same functionality as the central master station shown in
Figure 6. Alternatively, you can disable some of the advanced features, such as Mic
Kill, program inputs, etc. This will limit the station’s functionality to be a common
user station with multi-channel talk/listen capability.

Figure 12. Using the termination plugs supplied with the ES4000A for mixed
wet- and dry-line 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 US2000A 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.
