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 micro-
phone may be selected.
DC call enable: This may be turned on to use the intercom station with intercom sys-
tems 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.

13. Balanced / Unbalanced Selector Switch: This switch sets the intercom station for compati-
bility with either Audiocom or Clear-Com* intercom systems.
14. Mounting Holes (Figure 3): The “U” box is typically mounted in a wall. The “S” and “P”
boxes may be mounted on a wall, desktop, or console.

Before making connections, read the configuration notes that follow, and make sure
that all internal controls are properly set for your intended usage. If you need to ac-
cess the internal controls, remove the four screws on the front that secure the inter-
com station faceplate to the mounting box, then lift out the faceplate. Figure 2shows
the locations of the internal controls.
DIP Switches (Figure 2, item 2)
Table 1lists the DIP switch descriptions and factory default settings.
DC Call Enable (DIP Switch 2)
For Audiocom setup, leave this switch in the open position, and also leave the Bal-
anced / Unbalanced switch (Figure 2, item 13) in the Balanced position. For
Clear-Com setup, set DIP switch 2 to the closed position and set the Balanced / Un-
balanced switch in the Unbalanced position.

Incoming Call Beep (DIP Switch 3)
Incoming calls are always indicated by a red-flashing call key. If you also want in-
coming call beep in headphones, set DIP switch 3 to the Open position (default). DIP
switch 3 must also be in the Open position if you want to activate incoming call beep
to the speaker using DIP switch 5.
Dynamic Microphone Type Selection (DIP Switch 4)
If you will be using a headset, telephone-style handset, or dynamic handheld
microphone, and the specifications indicate the microphone type is balanced, leave
DIP switch 4 in the Open (default) position. If the specifications indicate an unbal-
anced microphone set this switch to the Closed position. If you are not sure, leave the
switch in the Open position for now, then try both positions during operation. Use the
position that produces the best audio quality at other stations.
