The leading manufacturer of sound masking & paging systems and complete acoustical solutions

Music Page Interface (MPI)

Model G505

Music Page Interface (MPI)
The MPI unit typically installs in the Telephone or IT closet. The MPI accepts a POTS line for all call and zoned telephone paging. In addition, there are left and right audio inputs for music or all-call page modification.

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 Spectra i.Net® Sound Masking System, the MPI provides the ability to program up to 99 individual zones for paging using standard DTMF tones through a POTS telephone wire. The system is also programmed for 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 Spectra i.Net’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® web browser using the included Lencore Sound Manager. No software or proprietary software needs to be installed on the client’s side. The Lencore Spectra i.Net® 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 Spectra i.Net® 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

  • 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 36-84 dBA as measured 1m from the center of the speaker
