Platform-Net

Model BP-Net

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

When a networked direct-fired speaker or system is required, the Lencore CrossNetOne™ system provides the highest level of sound quality and adjustability and offers the ability for network control. Through the system’s managing software, zones can be created and modified for masking and paging. On-going changes and additions to zones can all be handled through the network interface without the need to rewire the system.

Random sound masking source, coupled with Lencore’s E-Sound™ technology provide capabilities for:

Attenuation Adjustments: 96 in ½ dB steps
Contour Adjustments: 29 steps

Volume and contour adjustments can be made via the network simply and easily and uploaded to the system for immediate results. The system is also tunable by hand-held remote. Lencore is the only sound masking company that can offer both 3.5” and 6” speakers that offer the widest dispersion and best sound quality for direct-fired systems.

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

Sound Source: The Platform-Net
The heart of the CrossNetOne™ system is the Platform-Net, the primary sound source that produces, equalizes and distributes the sound for masking, music and paging. Each Platform-Net includes:

Random sound masking source, 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 CrossNetOne™ 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 Platform-Net Features and Capabilities:

Gathers instructions from the remote control or i.LON® and sends information and directions up to199 Platform-Nets 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 Platform-Net in the ceiling plenum, and eliminates the need for as-built drawings when checking or modifying the system.
Checks (during a diagnostic test) each Platform-Net for system performance, including the operation of the network, program, memory, power, and characteristics of sound masking.

Extreme Flexibility:
CrossNetOne’s™ sound source 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.

All masking/paging units must be UL Listed for air handling space.
System must confirm following ANSI standards: ANSI S1.4, ANSI S1.6, and ANSI S1.11.
System must meet ASTM 1130-02, ASTM E1573-02, ASTM E 1374-93, and ASTM E 1041-85 standards.
The Sound Masking system must use a unique integrated sound masking, music and paging system that uses the power of network technology, web appliances, internet access, infrared remote controls and digital signal processors (DSPs).
The Sound Masking system must be capable of separately and independently configuring zones for sound masking, paging and music via the network empowered through its central control.
