introduction
i.Net
®
Welcome to Lencore’s Spectra i.Net® system, the intelligent sound masking network!
What makes this system intelligent is its intuitive technology and its infinite flexibility
on an open-platform system. The system is suitable for any project size as large as
several million square feet, with its state-of-the-art, networked capabilities for sound
masking, music and paging.
The combined innovations of the complete sound masking system, sound sources,
speakers, power supply, i.Lon server, central online Sound Manager control and one-
touch remote control – put the Spectra i.Net® system on a new level of customization
and performance for sound quality, tuning flexibility, and more.
Like every Lencore Spectra® Sound Masking System, the Spectra i.Net® system achieves
uniform speech privacy throughout 100 percent of the space, plus sound comfort
(critical to ongoing use of any sound masking system).
INSTALLER BENEFITS
Installing a Spectra i.Net® masking system is faster and easier than any other sound
masking system, thanks to Lencore’s careful design of system components.
Standard RJ45 connectors are used throughout the system for connecting sound
masking speakers and OP to OP. This enables a plug and play installation and reduces
the need to strip and connect wires, saving installation time and ensuring a cleaner,
debris free installation. All wiring in the ceiling plenum is kept neat and organized with
modular connectors integrated into each speaker and OP.
Simplified connections add to the new system’s flexibility. Any changes or additions to
the network, such as channel, speaker or OP additions, layout modifications or zone
configurations can be made quickly.

NOTE TO THE INSTALLATION TEAM

You’re a Crucial Part of a Sound Decision
Working in an office environment poses a number of challenges to today’s workers;
among them, performing at high levels with more distractions than ever before to
contend with. You have been asked to play a part of the solution to two common and
often-neglected problems: privacy and noise.
Privacy and noise are big issues, especially in open office settings with a large number
of workstations or cubicles. And notably, in healthcare and related service fields,
protecting sensitive patient information is not just a top priority, it is the law.
The good news: utilizing a sound masking system is a cost effective solution. As
a qualified installer, you have become a crucial part of our client’s future
office environment. The equipment you are installing will play a vital role in not
only the privacy of our end user, but in their productivity and ability to concentrate
as well. A successful sound masking installation, in fact, should enable the people
who work in the environment to perform at their best.
You have been provided with state-of-the-art equipment and technology to install,
test, tune and finalize. As such, your goals for the completed installation should be:
Tuning the system to the proper dB level
Achieving proper sound uniformity
Managing expectations for the product
Sound masking involves much more than a series of speakers, switches and wiring
hidden somewhere above the ceiling. It has evolved into a science that literally affects
the way a workspace works.
Congratulations on being asked to perform a vital service for this client. You will leave
the workspace a better, more focused place to work. Those who will benefit from
your efforts will be better workers, and their companies more efficient, and you will
have made a contribution to their future success!
WHAT IS SOUND MASKING?
Sound masking is a means of adding background sound to a work environment to make
conversations more private (speech privacy) and to reduce extraneous conversations and
noise.
Masking systems have an integrated sound source, an amplifier, an equalizer, and
speakers that produce and carry an electronic sound that should be barely perceptible,
non-directional and harmoniously uniform throughout a given space.

You’re a Crucial Part of a Sound Decision
WHAT ARE THE CRITERIA FOR PERFORMANCE?
section 1
1.1 | basic information on sound masking
HOW DOES SOUND MASKING WORK?
Sound masking works because it changes the ‘dynamic range’ of sound in an
environment. Typically, the dynamic range in most environments is large, meaning
that there is a great degree of difference between the lowest, or ambient, sound level
and the highest levels of sound, when people are actively speaking and working.
Work environments are perceived as noisy precisely because of this large dynamic
range. The higher dB sound of normal speech is easily heard in a backdrop of a lower,
ambient background sound. Sound masking works by subtly raising the ambient
background sound level, thereby reducing sound’s dynamic range. This effectively
“masks” unwanted noise, makes speech unintelligible (creating privacy), and makes
the work environment acoustically comfortable.
The sound from a masking system must accomplish two things:
It must mask speech (providing measurable speech privacy)
It must not be a distraction (must be a “comfortable” sound)
1
2
How do you add sound with a masking system so that the system itself is not
distracting or annoying? The answer is by properly tuning the system to meet the
needs of the space. Lencore's system, when tuned properly, is very comfortable while
also creating speech privacy.
A sound masking system must be tuned so that the frequencies fall within the
preferred sound masking curve. The system should also utilize tight tolerances
for the decibel (dB) level within the space.
Spatial uniformity is also critical to a comfortable sound. Follow the tuning section
carefully and please call Lencore's main office if you have any questions.

.01-i.LON SmartServer The Lencore System uses an i.LON®
SmartServer as its head-end equipment to control the networked
system. The i.LON® SmartServer oers exceptional features, solid
construction, and the flexibility to monitor and control the system
from virtually anywhere.
.02-MPI
.03-Jordna Hub The Jordna Hub provides the ability to split the
system’s signal and distribute it to multiple points. It provides
an input that connects to the i.Net Operating Platform (OP) and
has four outputs that enable the hub to branch to other i.Net OP
locations in separate buildings or facilities. When the need for
wider system coverage and signal distribution is required, Jordna
Hubs can be connected to each other, providing clients with
almost infinite scalability to meet future growth.

.05-Power Supply The Lencore System uses a 36 or 48 Volt DC
power supply unit to power the i.Net OP. The power supply is
connected to the sound source (OP) using 2 conductor, plenum rated
16 gauge wire.
.06-OP The heart of the Spectra® i.Net® is the OP (Operating
Platform), the primary sound source that produces, equalizes and
distributes the sound for masking, music and paging.

.08-Speakers The Spectra i.Net® speakers enable the masking to
be distributed uniformly throughout the space. Typically hung
above the ceiling tiles, the speakers fill the plenum with sound that
gently filters into the environment below to create speech privacy.
Spectra i.Net® speakers are perfectly matched for the OP to ensure
the highest quality of sound masking
.09-Router A router ensures quality data transmission, paging and
music integrity across long cable runs. Each router terminates and
rebroadcasts signals back to full strength allowing the system wiring
network to work at best practices standards.

section 5
5.2 | i.Net OP and speaker placement
HELPFUL HINT
It may be helpful to mark each speaker with a magic marker on the bottom for each OP, each
channel and speaker number, for example: OP #1, channel 1 - mark the speaker OP1A. Also when you
get to the end speaker on each channel, add “END” to this designation.
Place the i.Net speakers by walking the floor and set the speakers on the floor at
approximate installation locations.
Place OPs on the floor at approximate locations (check drawing for correct sequence).
Make sure the OPs are not put in harm’s way of people working or walking.
NEVER PLUG AN i.NET OP INTO ANY COMPUTER OR NETWORK EQUIPMENT
OTHER THAN AN i.LON OR ANOTHER OP.
NEVER INSTALL POWER WIRES WHILE THE POWER IS ON. IT IS DANGEROUS AND
WILL DAMAGE THE OPs, ONLY TURN THE POWER ON WHEN THE POWER WIRES ARE
FULLY AND PROPERLY WIRED AND INSTALLED.
INSTALLATION
IMPORTANT: Lencore suggests installing equipment in this sequence:
Hang speakers*
Hang OPs
Run wire with power OFF
ATTENTION: DO NOT HOOK UP POWER UNTIL THE SYSTEM IS FULLY
INSTALLED. POWER CONNECTIONS MUST BE DOUBLE-CHECKED TO
ENSURE PROPER POLARITY.
CRITICAL: CHECK WIRING POLARITY (+ AND -) BEFORE FIRING THE SYSTEM ON,
OTHERWISE, IRREVERSIBLE DAMAGE WILL OCCUR TO SOME OR ALL OF THE OPs.
* Speaker units will hang from the ceiling using the attached chain (supplied by Lencore).
Chain length should be cut to enable each speaker to hang a minimum of 6” above the ceiling
tile and a maximum of 12” above the ceiling tile, unless otherwise noted on the drawing.
NOTE: TO HELP MAINTAIN UNIFORMITY, KEEP THE CHAIN LENGTHS/HEIGHTS
CONSISTENT THROUGHOUT THE INSTALLATION AND SPACE.
