by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table
specified by the manufacturer, or sold with the
apparatus. When a cart is used, use caution when
moving the cart/apparatus combination to avoid
injury from tip-over.
13. Unplug this apparatus during lightning storms or
when unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.
15. WARNING: To reduce the risk of fire or electric shock,
this apparatus should not be exposed to rain or
moisture and objects filled with liquids, such as

GENERAL DESCRIPTION
Polk Audio LCi-IP ultra high performance loudspeakers
are among the world's first active IP in-wall and
in-ceiling loudspeakers. They were created for IP-net-
worked systems but are also compatible with analog
systems. A network decoder card (sold separately), built-
in Digital Signal Processor (DSP) and the Performance
Optimization Wizard enables every LCi-IP speaker to be
set up for maximum performance in any room environ-
ment. What’s more, LCi-IP speakers already come with an
award-winning reputation, because they use the same
driver technologies as Polk Audio's award winning
high-end LSi Series.
The built-in DSP controls the electronic crossover,
frequency equalization, bass enhancement and room
optimization. Performance Optimization Wizard software,
which integrators can use via a USB port and a PC, or
on the internet through a network such as NetStreams™,
optimizes each speaker for its location and room environ-
ment. Depending on the speaker and its location, and the
configuration of the room and its acoustics, you may
be asked to take a series of measurements, which
you would then input into the Performance
Optimization Wizard.
ACTIVE IP LOUDSPEAKER FEATURES
• With an open architecture network decoder card such
as the StreamNet™ card and an Ethernet cable,
integration with any system capable of streaming
packet-switched audio in WAV or MP-3 format and
TCP-IP control is possible.
• Pure digital signal all the way to the power amplifier
outputs, with no losses and superb fidelity.
• Speakers automatically announce themselves to
an open architective network via a network
decoder card.
Self Amplified
• Amplifier at speaker minimizes losses associated
with long runs of cable and passive crossover parts,
creating higher fidelity.
• Efficient, cool running digital amplifiers.
• Bi-amplified (LC265i-IP is tri-amplified) with electronic
crossover minimizes power loss and phase shift
for better sound.
• High Power for incredible dynamic range.
• Powered by 48V DC local power supply
(sold separately).
Built-In DSP
• DSP allows unprecedented room optimization EQ for
sound quality that can exceed free-standing speakers.
Peformance Optimization Wizard
•Use the Performance Optimization Wizard software
with a PC connected via a mini USB port located on
the front baffle of each speaker, or through the internet
when the speakers are used in an IP network via a
network decoder card. The software’s user interface
makes the speaker position and room acoustics
optimization virtually foolproof.
LCi-IP Speaker Technology:
• Foamed Polypropylene Dynamic Balance™ Cones
(LC265i-IP): stiff and yet surprisingly lightweight-20%
lighter than conventional polypropylene and 35%
lighter than aluminum cones for spectacular midrange
clarity, punchy bass and high efficiency.
• Casket Basket ® : composite driver baskets keep
moving parts in rigid alignment and damps
performance-robbing resonance.
• The LC265i was the first in-wall speaker to feature
the patented Power Port™ bass venting system for
superior bass response with low distortion.
• Available Performance Enclosures deliver consistent
room-to-room performance, improves bass and
sound transmission.
• Round model (LC80i-IP) features 15° Driver Offset
for better midrange clarity and imaging anywhere
in the room.
• Ring Radiator tweeters (the same tweeters used in
the LSi Series) for smooth, extended highs with
incredible accuracy and astonishing detail.
