Polycom Vortex EF2241 Quick Installation Manual

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).

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.
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.
Please refer to the respective User Guides for each product for detailed installation, warranty and support information.
