Music Page Interface (MPI)

Model G5

Music Page Interface (MPI)

Lencore Music Page Interface (MPI) replaces all the bulky head end equipment that that is associated with music and paging systems. With the MPI there is no need for additional cable home-runs, amplifiers, separate equalizers, special switching equipment or matching vendors for compatible product interfaces. In fact, the MPI technology is so sophisticated that it can make zone additions, modifications, deletions and other changes to the paging system on the fly, without rewiring, and eliminates the need for running multiple home runs back to the electrical closet or through building risers to create separate or additional zones.

When connected to the Lencore CrossNetOne™ Sound Masking System, the MPI provides the ability to program up to 100 zones for paging using standard DTMF tones through a POTS telephone wire, including all call and emergency broadcast paging. The system’s easy to use full one octave band equalizer can be adjusted to either individual zones or can be adjusted for all zones and provides exceptional fine tuning capabilities.

When the MPI is connected to the CrossNetOne’s™ web appliance (i.LON®) programming can be set for up to 1.5 million square feet of space through a single device. The creation, modification, addition and deletion of zones or groups for paging and masking can be easily controlled through the i.LON’s®100 web browser using the included Lencore Sound Manager. No software or proprietary software needs to be installed on the client’s side. The Lencore CrossNetOne™ System is an open platform system. In addition, volume and equalizer settings for paging and music can be programmed through the Sound Manager offering tremendous adjustment and control capabilities with unprecedented flexibility.

The unmatched capabilities and superior paging quality of Lencore’s system automatically compensates and readjusts for frequency line loss while ensuring a quality signal that is continuously and uniformly broadcast and distributed throughout the entire system. Essentially this means that throughout the miles of audio wire, line loss will be virtually negligible. This results in a crystal clear page whenever you need it, wherever you are in your facility.

These features and qualities are just some of the benefits of the Lencore CrossNetOne™ System that make it the only networked sound masking system uniquely qualified to support the masking, paging and music needs for any facility with adjustment capabilities unsurpassed in the industry

  • 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.
  • The Sound Masking system must produce 20Hz through 20,000Hz from its source.
  • The masking must be random and provide a minimum pattern of no LESS than 25 hours.
  • The sound masking devices must provide both a 1/3 octave band equalizer for a minimum of 30 bands and a parametric equalizer to adjust the sound masking.
  • The paging devices must have a minimum of a 1/1 octave band equalizer to shape sound.
  • The masking volume shall be adjustable via digital means for ½ dB steps for a range of 30-78 dBA as measured 1m from the center of the speaker
  • System must provide two sizes of speaker: 3 ½" and 6".
  • 3 ½" speaker housing must be produced from recycled ABS material. 6" speaker housings/enclosures must be damped to avoid undesirable resonance.
  • Sound masking system must be able to provide music muting capabilities to allow paging to smoothly override masking.
  • Spatial uniformity of sound must be no more than ±½ dBA.
  • Sound masking, paging and music must have individual identifiers located in an integrated LCD screen.
  • Plenum mounted network locations must have a lighted LED for visual inspection.
  • System must be a multi-drop network system. Point to point systems are unacceptable.
  • System must be capable of being tuned through a network and a hand-held remote.
  • The system must be capable of being independently zoned on both a global and local level for sound masking, paging and music. All zoning must be controlled from a network appliance.
  • Generation and integration of multiple random sound masking sources and by using E-sound® technology equates to the best sound and effective sound masking.
  • System must be capable of performing a complete diagnostics of its entire functions including diagnostics of the network, hubs, nodes, routers, DSPs, memory, circuitry, amplifiers and power.
  • System must be capable of reporting entire settings for each zone for masking, paging and music indicating at a minimum the volume, contour, 1/3rd band octave equalization, parametric equalization, diagnostics, and groupings.
  • System must be an open platform system. Proprietary software systems are UNACCEPTABLE.
  • System must be capable of using off the shelf browser software for full manipulation.
  • System must be capable of being used as a stand-alone system or a system tied into an intranet IT spine or manipulated through the internet.
  • System shall be designed so that individual speaker or component failure will have no impact on the balance of the system.
