Music Paging Interface (MPI)
Lencore’s sound masking systems can
easily provide paging and music with a few
simple additions using a telephone
connection or music RCA connection –
virtually giving you two systems (masking
and paging) for the price of one.
The advantages of Lencore’s paging and
music capabilities include:
x Paging and music volume adjusts
independently of masking volume
control, with Lencore’s IndePage
technology.
x Paging and music come through
uniformly, with no “hot” and “cold” spots
common to other systems.
x No abrupt “starts” and “stops” because
Lencore’s paging is programmed to
smoothly override masking.
Note: When working with the MPI be sure to utilize a ground
strap to insure that a common ground is maintained between
all system components.
The MPI has two separate audio channels (one for paging, one for music) and through
the MPI board, permits zoned paging and/or music with the customers’ own telephone
system.
Speakers
Speakers used in the Spectra i.Net
system
are configured with integrated RJ45
connections for plug and play and ease of
installation. The speakers feature an
aluminum housing, 5-inch wide dispersion
and weigh approximately three pounds
each.
In certain applications and site conditions, a
direct field speaker or inverted speaker
may be necessary. Lencore provides this
option with all of its sound masking
systems.
