Loudspeaker Installation
Loudspeakers should be installed and connected before powering up the system.
For each loudspeaker:
1. Remove two ceiling tiles (indicated by the black squares in Diagram A at right). You will
place the loudspeaker in one space and use the second space for making connections.
2. Install the loudspeaker with the grille facing into the room (Diagram B). See the loudspeaker
installation instructions for more information.
3. When both loudspeakers have been placed in the desired ceiling locations, connect them in
parallel (per the Loudspeaker Wiring instructions below) using the supplied plenum rated
speaker cable.
4. After wiring connections have been made, re-install ceiling tiles in the empty spaces.
(Diagram C).
Loudspeaker Wiring
The two supplied loudspeakers must be connected in parallel to ensure correct
operation. Connect the positive (+) wire of each loudspeaker, along with a wire
from the cable running to the positive (+) terminal of the Vortex EF2241’s loud-
speaker connections, together using a wire cap. Repeat the process for the neg-
ative (-) wires and terminal connection on the Vortex EF2241.

Each loudspeaker provides 120° coverage angle and has a sensitivity of at
least 85dB SPL 1W/1m. As shown at right, assuming a 9 foot (2.7m) ceiling
height and a 3.5 foot (1.1m) ear height, the loudspeaker coverage pattern is a
circle with a 19 foot (5.8m) diameter (drawn from the center of the loudspeak-
er). A 10 foot (3m) ceiling height yields a 22 foot (6.7m) radius of coverage.
Using the 10 foot (3m) ceiling height as the worst case scenario and assuming
that the Vortex EF2241 amplifier is providing 1W to the loudspeaker, the listen-
er will hear a signal with 79dB SPL.

Installation Instructions
1. Mount the Vortex EF2241 in a convenient location such as in a credenza, in a rollabout cart, or under the
table. If you are mounting the unit under the table, use the supplied brackets, mounting hardware and
template as follows:
a. Tape the template under the table, making sure you have provided at least 17” of clearance from the
edges of the table to any edge of the template. This will prevent seated guests from bumping into the
Vortex unit.
b. Drill 3/32” starter holes where marked on the template. You will drill two holes for each of the front
brackets and one hole for the rear bracket.
c. Remove the template if desired.
d. Install the two Front “L” brackets and the Rear “Z” bracket using the provided #6 pan head screws.
e. After installing the front and rear brackets, attach one gray rubber adhesive foot to the top of the Vortex
EF2241 at each of the four corners. This will keep the unit secure against the table.
f. Slide the Vortex EF2241 into the rear bracket, align the front panel mounting holes with the “L” brackets,
and secure the unit using the four black 10-32 x 1/2” mounting screws provided with the Vortex.

2. Connect the analog PSTN telephone line to the SoundStation VTX 1000 Interface Module (item D in diagram at left). Note that if you want to connect
a second telephone line to the system, you can use the LINE and PHONE jacks of the Vortex EF2241. Refer to the Vortex EF2241 User Manual for
more information, or see the White Paper “Interfacing Vortex and the SoundStation VTX 1000” on the Polycom website.
3. Connect the Auxiliary Output of the Interface Module (item D in diagram at left) to Input A on the Vortex EF2241 (item G in diagram at left).
4. Connect Output A of the Vortex EF2241 (item E in diagram at left) to the Auxiliary Input of the Interface Module (item D).
5. Connect the cables for the supplied microphones (item H in diagram at left) to Mic/Line inputs 1-4 of the Vortex EF2241 (item F).
6. Connect the SoundStation VTX 1000 conferencing unit to the interface module as shown (left, lower diagram).
7. Install the ceiling loudspeakers as shown on the rear page of this guide. (See wiring diagram on rear page for information on connecting loudspeakers
in parallel.)
8. Run the supplied plenum rated speaker cables between the desired ceiling locations (item A in diagram at left) and the Vortex EF2241. The cables can
be run through conduit or down a corner of the wall. Connect the speakers in parallel to the loudspeaker terminals on the Vortex EF2241 (item B). For
more information on parallel loudspeaker connection, see the rear page of this guide.
9. Place the boundary microphones at the desired locations on the conference table. Note that boundary microphones work best when placed on a hard,
flat surface and that they should not be obstructed with papers or equipment. Connect the supplied microphone cables to the microphones.
10. Connect Output B of the Vortex EF2241 (item E in diagram at left) to the external audio input of your video codec (item I).
11. Connect an external audio output of your video codec (item J in diagram at left) to Line Input B of the Vortex EF2241 (item G). Note that only one
channel of your video codec’s external audio will be used.
12. Disable the internal echo canceller in your video conferencing codec so that it does not conflict with the echo canceller in the Vortex EF2241. See your
codec manual for details. For more information, see the Application Note “Interfacing to Video Codecs” on the Polycom website.
For the Polycom VSX 7000 video conferencing codec:
a. After making audio connections (use input/output 1 on the VSX 7000), power up your VSX 7000 and select SYSTEM, ADMIN SETTINGS, AUDIO
SETTINGS within the video codec and select NEXT for Page 2.
b. Select the AUDIO MIXER option for the Line input that is connected to the Vortex device, and select MONITOR - FAR SITE AUDIO for the Line
output. For both settings leave the LEVEL settings at 5.
c. The loudspeaker in the VSX 7000 console should also be disabled. Go to SYSTEM, ADMIN SETTINGS, AUDIO SETTINGS, and select NEXT, NEXT
for page 3. Select OFF for MIDRANGE SPEAKER. Depending on the type of loudspeakers you are using, you may want to lower and/or disable
the Subwoofer. Make those changes in the SUBWOOFER SPEAKER and SUBWOOFER OFFSET sections.
13. Connect the Vortex EF2241 and the SoundStation VTX 1000 Interface Module to power.
