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.
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.
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
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

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.

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.”
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.
milliseconds; with CFG switch set to “B,” delay is
4.4milliseconds. 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.
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.
•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).

Important Note: Always save your newly configured settings to the DSP.
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.
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.
