THE MM-4XP MINIATURE LOUDSPEAKER
The MM-4XP miniature loudspeaker is a self-powered loud-
speaker designed for high-quality distributed systems.
Housed in a compact aluminum enclosure, the MM-4XP is
especially suitable for installations involving space limita-
tions and visibility concerns. The loudspeaker’s proprietary
4-inch cone transducer, manufactured at Meyer Sound's
Berkeley factory, delivers an impressive maximum peak SPL
of 113 dB (measured with music referred to 1 meter), and
has a wide operating frequency range of 120 Hz to 18 kHz
with very low distortion. The MM-4XP exhibits the same high
intelligibility and flat frequency and phase responses for
which Meyer Sound loudspeakers are known. Peak and rms
limiters regulate loudspeaker temperatures and excursion,
ensuring that the MM-4XP performs exceedingly well even
when driven into overload.
The MM-4XP's amplifier and signal-processing circuits are
designed to store DC power and tolerate voltage drops,
thereby accommodating light-gauge cables and long cable
runs. The MM-4XP receives balanced audio and DC power
from a SwitchCraft® EN3™ 5-pin male connector on its rear
panel. The sealed EN3 connector provides protection
against harsh environmental conditions when the MM-4XP
is installed outdoors.
