Polk Audio LC80i-IP - Manual (Page 4)

Figure 2
Note: Most measurements will be taken from
the center of the tweeters. To take these measure-
ments, you will need: a tape measure and a
protractor. You may also be able to determine
the necessary measurements from a blueprint
or floorplan.
Figure 3
• Included with each setup question and physical
measurement, there is a help link that defines
a particular question or measurement in more
detail. Click on the link to call up the help
screen (figure 3).
Figure 4
• An “Error Message” will be displayed if you
do not supply information. For some requested
measurements you may not be able to supply
the requested information, and you may check
the appropriate “skip question” box. When an
“skip question” box is checked, no error
message is displayed (figure 4).
Making A Speaker Configuration File Offsite
To help you work more efficiently and save time,
you can make a speaker configuration file offsite.
You will need to have installed the speakers, be
familiar with the room environment and have taken
the necessary measurements. Once on site, you can
download the file and audition the system, making
any final EQ adjustments as deemed necessary.
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 vol-
ume 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.”

Important Note: Always save your newly
configured settings to the DSP.
INTERPRETING THE LEDS
An LED indicator tells you the status
of each speaker:
An ORANGE LED indicates the speaker
is in STANDBY.
A GREEN LED indicates the speaker is ON.
A RED LED indicates the speaker is in
PROTECTION mode.
Reset Button Reminder
Engage the RESET BUTTON whenever you:
• 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.

FAQs
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). With 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
LCi-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
a wireless USB connector to control it from my
computer?
No. The speaker is not an USB host. A wired
connection to a PC is required.
What is the reset button for?
Press the RESET button whenever you reconfigure
the speaker switch settings, update the firmware
on the network decoder card or update the
amplifier’s firmware.
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 LC80i-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 LC265i-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?
Yes. We recommend that you always use a
surge protector.
