Important Note: If installing LCi-IP speakers in an external wall, the operating ambient temperature of the speakers is 0-50° C (32-122° F). For most types of construction, the external walls will be insulated,

but it is important that insulation does not come in contact with the speaker’s amplifier.

Cable runs up to 100 feet should have a capacitance of 20pF/ft. For cable runs greater than 100 ft. call Customer Serivce at 1-800-377-7655.

When you can't install a Performance Enclosure but want to get better bass, install fire breaks above and below the speaker position to make an ideal-volume enclosure. Also, a layer of fiberglass or Dacron

behind the speaker helps. Note: Leave space around the speaker’s amplifier; insulating material must not come in contact with the amplifier.

WIRE RECOMMENDATIONS

Network Line

Shielded Cat-5 cable with RJ-45 connectors. Wiring termination convention should be the same at both ends of the cable.

COMM Line

Shielded Cat-5 cable with RJ-45 connectors. Wiring termination convention should be the same at both ends of the cable.

Analog Line

the amplifier located on the back of each speaker.

• Never kink or bend any cable, nor should any

cable interfere with other cables.

• Never try to make a short cable reach, ever.

• Avoid long cable runs if possible — the shorter

the cable, the better the sound quality. Do, however, ensure that your cables are long enough.

• Cable should be at least 3 feet away from

fluorescent light boxes and other sources of electrical interference.

• Label both ends of each cable.

• Always keep AC power cords and analog

power cords separate.

INSTALLING THE NETWORK DECODER CARD

Introduction

You will need to install a netword decoder card to use the “network.” Follow the directions below to install the card. There is also a series of schematic diagrams (on page 38) to help you properly connect the speakers to a network or analog system.

Note: A network decoder card is not needed to use the analog RCAs.

Step 1: Disconnect all cables. Step 2: Remove the (4) screws holding the heat

sink to the amplifier housing. Set the

screws safely aside.

Step 3: Remove the amplifier and loose cables

from the amplifier housing.

Step 4: Remove the two screws from the two

metal standoffs located on the PCB.

Step 5: Install the network decoder card on the

standoffs, mating the two sides of the 40-pin connector

. Press down and ensure that the card snaps onto the two plastic standoffs.

Step 6: Secure the network decoder card by

reinserting the two standoff screws into the two metal standoffs.

Step 7: Reinstall the amplifier onto the amplifier

chassis (reversing steps 1, 2 & 3).

• Should you have any questions before or during the setup process, please feel free to contact Polk Audio

Installer Support Services at 1-800-377-POLK.

Walking Through the Room Optimization Choices

• This program can be used for installing and

setting up in-wall or in-ceiling LC

Auditioning and Final EQ Adjustments

Adjusting the EQ gives you the opportunity to fine tune the system’s performance (figure 5). You should be in the center of the listening area, with the volume set at an appropriate level. Play audio through the system, and listen for problems such as:

Muddy vocals or instruments Too bright/Too dull ”Boomy” sounds Thin sounding bass ”Harsh” vocals or instruments

If the system sounds good,no changes are recommended. When you have finished listening, press ”Finish.”

• Reconfigure speaker switch settings.

• Update the firmware on the network decoder card.

• Update the amplifier’s firmware.

Note: Each speaker has a RESET BUTTON, which is located on the front of the speaker.

Reset button

Will the speakers work with my current MRAV system?

Please check with your MRAV Authorized Installer.

Is there any inherent delay in the system?

Inherent delay for each speaker is based on position of configuration switch (CFG). W

ith CFG switch set to “A,” the delay from input to speaker output is 2.5 milliseconds; with CFG switch set to “B,” delay is

4.4 milliseconds. There is no delay from speaker to speaker. Any other delay is from the AV system.

How much heat can these speakers take?

The ambient operating temperature range of the LC

i-IP speakers is 0-50C (32-122F).

What about the amplifier and wall insulation?

The amplifier should never come into contact with any wall insulation.

What are the switch settings on the back of the speaker’

s baffle for?

These settings affect the configuration of the speakers (see page 5).

Do I need to run the Performance Optimization Wizard in order to listen to the speakers?

No. The speakers are loaded with factory default settings. These speakers were designed to sound great right out of the box. If you want them to sound better or configure them to be used with your MRAV, then you will need to use the software.

Can I run analog lines to each speaker but use the COMM line to control everything?

Yes, this is a supported configuration (see page 40).

What gauge wire do you recommend for the power connections?

We recommend 14 gauge wire. You may use 16 gauge, but at a cost to performance.

If I install a LC80i-IP in the ceiling but don’t connect via a network decoder card, can I use

om my

eless USB connector to contr

a wir

ol it fr

computer?

No. The speaker is not an USB host. A wired connection to a PC is r

equired.

What happens to the speaker settings if I temporarily lose power?

If you are using the default settings or saved any settings to the DSP from the POW, they will be present in the system when you power back up. We recommend that you also save your POW settings by storing the configuration file on your hard drive. This is an available option inside of the Performance Optimization Wizard program.

Can I install a speaker under a water source, such as putting an LC80

i-IP in a ceiling under

a bathroom tub?

We do not recommend installing any speaker near a water source because of potential leaks.

Can I mount LCi-IP speakers in an external wall?

Yes, as long as the wall’s insulation doesn’t come in contact with the amplifier.

Can I mount LCi-IP speakers so that they are outside?

No. These speakers are for indoor use only.

Whose power supply can I use?

You can use the Polk Audio SPS-1 power supply or a similar power supply such as an available NetStreams power supply. Be aware that the SPS-1 can power both the LC265

i-IP and LC80i-IP speakers. Be sure to check the voltage and current ratings on third party power supplies to achieve optimal performance.

Can I put the SPS-1 power supply on a power circuit with other devices, or does it need its own circuit?

The power supply does not need to be on its own circuit, but ensure that you are not exceeding the current draw limitations of the circuit.

Should I use a surge protector?

ecommend that you always use a

e r

es. W

Y surge protector.
