Description
The SS1000 and SS2000 Intercom Speaker Stations may be used with a headset, or
with the built-in speaker and an optional gooseneck panel microphone, or with head-
phones and an optional gooseneck microphone. As an alternative to a headset, a tele-
phone style handset may also be used. The SS1000 is a single-channel station; the
SS2000 provides switch-selectable access to either of two intercom channels. Both
the SS1000 and SS2000 come in three versions to suit a variety of applications. The
“S” box is a portable version. It has a carrying handle and dual “loop-through” inter-
com connectors which permit stations to be quickly interconnected using prefabri-
cated cables. The “P” box is a stationary version. It also has dual “loop-through”
connectors for quick interconnection, but the case is designed for desktop or
console-mount applications. The “U” box is designed for permanent, in-the-wall
mounting. It uses quick release terminals for connection to the intercom system.

Features
1. Channel and Power Connections: The "U" box uses quick release terminals to connect au-
dio and power wires. For the “S” box and “P” box versions, the terminal connections are
brought out to the dual, loop-thru XLR connectors on the side of the box. These permit
several stations to be connected in a string, or daisy-chain, using prefabricated intercom
cables.
2. Configuration DIP switches: These switches control the following features:
Call Beep: In addition to a flashing call key indication for incoming calls, an incoming
call beep tone can also be used.
Headset Microphone Type Selection: Either a balanced or unbalanced dynamic microphone may be selected.
DC call enable: This may be turned on to use the intercom station with intercom systems that use DC call signaling.
3. Panel Mic Key: Selects the Panel Mic connector (11) in the on position and the Headset
connector (10) in the off position.
4. Speaker Key: Selects the built-in speaker in the on position and the Headset connector
(10) in the off position.
5. Channel Select Key (SS2000 Only): Selects intercom channel 1 or 2. The key lights green
for channel 1 and red for channel 2.
6. Volume Control: Adjusts intercom listen volume to headphones or speaker.
7. Intercom Listen Key: Both momentary (push-to-listen) and latching (hands-free listen)
are possible.
8. Call Key: Used to send call signals on the intercom channel. Flashes for incoming calls.
9. Intercom Talk Key: Both momentary (push-to-talk) and latching (hands-free talk) are pos-
sible. The SS1000 / SS2000 also features a "mic kill receive" circuit, which allows an op-
erator at a remote master station (such as the US2000A) to turn off the SS1000 / SS2000
talk key.
10. Dynamic-Mic Headset Connector: 4-pin male XLR connector accepts headsets with mon-
aural headphones and either a balanced or unbalanced dynamic microphone. Also accepts
a telephone style handset. Can also be used with headphones when a Panel Mic is con-
nected. Or, can be used with a handheld microphone along with the internal speaker.
11. Panel Mic / Electret-mic Headset Connector: Accepts an electret gooseneck microphone,
such as the Telex Model EGM-12N or EGM-18N.
12. Sidetone Trimmers: These adjust the level of the user's own voice in the headphones
when using full-cushion headphones. (Eliminates the muffled sensation when talking
with the ears completely covered.) When using the speaker or open-ear style headphones,
the sidetone trimmers are adjusted to eliminate the user's voice from the headphones or
speaker. This helps to prevent feedback.

Intercom Channel Connections
The method of connection depends on the type of box. The “S” box and “P” box versions connect to the intercom system using prefabricated cables in a phantom-powered configuration, as described below and illustrated in Figure 4. The “U”
box version is designed for permanent installation, and it can be either phantom powered or locally powered. Examples are shown in Figures 6 and 7.
Description of Phantom Powered Connection
In this method, operating power and intercom audio for the entire intercom system
are carried over the same wires. The advantage of this method is simplicity of connection. Also, the system power supply (PS2000L, SPS2000A etc.) automatically
provides what is known as a terminating impedance for the intercom system. Without
this terminating impedance, the sound quality will be very distorted, and the levels
will shift every time additional stations are connected. The disadvantage of the phantom power method is that some operating power is lost over very long intercom cables, and performance at distant intercom stations may be reduced. Generally, if
intercom stations are within a few hundred feet from the system power supply, phantom power will be sufficient. Also note that increasing the number of stations will reduce the overall operating distance. Phantom power is generally the only method that
will be used to connect the “S” and “P” box versions, since these versions are usually
connected with relatively short cables of less than 200 ft. Figure 4
trates a phantom powered intercom system with "S" and "P" type stations. Figure 6,
page 15, illustrates phantom power for "U" boxes.
Note that the distance over which power can be delivered is less than the distance
over which audio can be delivered. Audio can be delivered for several miles to locally powered stations as described below.
Description of Locally Powered Connection
Only the "U" box has provisions for local power. The 3-pin connectors on the
☞
"S" box and "P" box do not permit this type of connection.
, page 13, illus-
11
Page 12
Audiocom®
Using this method, an intercom station is connected to the intercom line just like any
phantom-powered intercom station, except that a local power supply is also connected. This local power supply is located with the intercom station and provides
power for that station only. Since power loss on the intercom lines is no longer an issue, the operating range is now limited only by the audio transmission range, which
is several miles. Another advantage to this method is that more stations can be connected to the intercom channels. When local power is supplied to an intercom station, the station detects this and automatically disconnects from the system's
phantom power supply.
Figure 6
ered "U" boxes. As long as a system power supply (PS2000L, SPS2000A, etc.) is located somewhere in the intercom system, the proper terminating impedance will still be
supplied for all stations. However ,if all stations are locally powered, and there is no
system power supply ,a special line termination must be installed as described below.
All Locally Powered Intercom Stations (Dry Lines)
If intercom stations are widely distributed, you can dispense with a system power
supply (PS2000L, SPS2000A, etc.) and use local power for each station. When no
power is delivered on the intercom channels, this is known as dry-line operation.
Since a system power supply is not used, a line termination must be inserted in each
intercom channel for proper operation. Again, note that only the "U" box has provisions for local power. The 3-pin connectors on the "S" box and "P" box do not permit
this type of connection. Figure 7 illustrates an intercom system using all locally powered "U" boxes.

Figure 6. A two-channel Audiocom intercom system using a PS2000L Power Supply
with “U” boxes. The PS2000L is set to isolate mode. In isolate mode, each intercom
channel is a separate party line, and total current for each channel is limited to 1
amp. Note that both SS1000 and SS2000 stations may be connected, depending on
each locations’ need to communicate with one or two channels. SS1000 stations may
be connected to either channel one or two. Also note that locally powered stations
may be connected. This is recommended when stations are installed at remote
locations. Since the PS2000L provides termination for the intercom channels, no
user-installed termination is required. For SS1000 connection details refer to Figure 8

Power-Up
Make sure any local power supplies are plugged in, then turn on the power switches
of any phantom power supplies (PS2000L, SPS2000A etc.).
If you are using a large number of locally powered intercom stations, you should
☞
activate their local power supplies before activating any phantom power supply.
Otherwise, you may get an overload indication on the phantom supply. In this
case, either reset the phantom supply, or momentarily turn it off, then on.
Sidetone Adjustment
The SS1000 and SS2000 use full-duplex audio (the same as con v entionaltelephone
lines) in which the talk and listen audio are sent and received on the same wires. Thus,
when you talk, you also here your own voice back as with a telephone. If you are using
the built-in speaker for listening and a panel microphone or handheld microphone for
talkback, you could experience unwanted feedback, since the microphone may pick up
your returned voice audio from the speaker and re-amplify it. This could also happen if
you are using a headset or headphones with open-ear style earmuffs. On the other hand,
if you are using earmuffs that completely enclose the ears, the microphone is not likely
to pick up the returned audio. And, a certain amount of your own voice level is desirable to overcome the muffled sensation when talking. The sidetone adjustment is different for these different operating conditions:
If you are using the speaker with a panel microphone, or if you are using an
open-ear style headset or headphones, adjust sidetone as follows:
1. SS2000 only: activate channel 1 as described in the operating instructions, page
.
22
2. Activate talk and listen as described in the operating instructions.
3. Slowly increase the volume to maximum while talking into the microphone.
4. Using a small flat-bladed screwdriver, adjust the channel 1 sidetone trimmer (Fig-
, page 6, item 12) to minimize your voice level in the headphones.
ure 2
20
Page 21
5. SS2000 only: activate channel 2 and repeat the above steps to adjust the channel
2 sidetone.
6. Install the intercom station mounting screws after completing the adjustments.
The station is now ready for use.
If you are using headphones that completely enclose the ears, adjust sidetone as
follows:
1. SS2000 only: activate channel 1 as described in the operating instructions on
