Operating Platform (OP)

Model G20

OP is UL Listed and approved for use in air-handling spaces.

What makes Lencore’s Spectra i.Net™ system intelligent is its intuitive technology and its infinite flexibility on an open-platform system to suit any project size. The combined innovations of the complete sound masking system – sound source, speakers, power supply; i.LON^®, music page interface, equalizers, online Sound Manager control and one-touch remote control put the Spectra i.Net™ system on a new level of customization and performance.

The Spectra i.Net™ system is the most sophisticated masking system available when a network system is required. The system features fast, complete control over every sound frequency for masking. Extreme design flexibility, plus, easy system expansion with the addition of sound sources and speakers to the network. Sound control with the click of the remote or mouse, even off-site. Preferred, award-winning sound quality, only from Lencore’s Systems.

Sound Source: The OP
The heart of the Spectra i.Net™ system is the OP (Operating Platform), the primary sound source that produces, equalizes and distributes the sound for masking, music and paging. Each OP includes:

Multiple, random sound masking sources, coupled with Lencore’s E-sound™ technology, produce a sound quality that is random, making it exceptionally comfortable environment.
Independent equalizers for unprecedented tuning where every channel of the system has a separate and independent 1/3rd octave band equalizer or parametric equalizer. Sound frequencies and contour can be adjusted and set to any point on the acoustical curve, from 20 Hz to 20 kHz, making the Spectra i.Net™ the first networked sound masking system to make fine-tuning the entire spectrum of sound possible.

The network is intelligent enough to bypass any failure in the system to keep communicating throughout the entire network. Competitor’s point-to-point networks can not achieve this level of connectivity and diagnostic control.

Additional OP Features and Capabilities:
Gathers instructions from the remote control or i.LON^® and sends information and directions up to199 OPs within the network for system tuning and modifications.

Displays information on its integrated LCD screen, including the specific address of the respective enclosure. This address aids in locating the correct OP in the ceiling plenum, and eliminates the need for as-built drawings when checking or modifying the system.

Checks (during a diagnostic test) each OP for system performance, including the operation of the network, program, memory, power, and characteristics of sound masking.

Extreme Flexibility:
Groupings of sound sources and channels let you customize an almost limitless amount of zones for masking, paging and music, while maintaining the advantages of complete networked operation and control.
