M4
M4 loudspeaker
The M4 is a high performance stage monitor employing an integrated
15”/1.3” exit coaxial driver design with neodymium magnet and
constant directivity horn loading. Its dispersion of 50° x 70° (hor. x
vert.) provides an accurately defined coverage area on stage. Used
upright the M4 serves as a powerful front PA speaker (70° x 50°) for
various applications.
The M4 is a two-way design with a built-in passive crossover network.
It can optionally be operated in two-way active mode just by changing
the configuration of the D12 amplifier without any modifications to the
loudspeaker. Its frequency response extends from 55 Hz to above
17 kHz.
The M4 cabinet is constructed from marine plywood and has an impact
resistant paint finish. The front of the loudspeaker cabinet is protected
by a rigid metal grill in front of a replaceable acoustically transparent
foam. The side panels incorporate a pair of handles, a pole mount
socket and four M10 threaded inserts to connect to different rigging
devices and brackets. Two runners recessed in its bottom panel protect
the cabinet from scratching and prevent unwanted movement.
Connections
Connector wiring
The M4 cabinet is fitted with a pair of EP5 connectors. All pins of both
connectors are wired in parallel. Using the male connector as the input,
the female connector allows for direct connection to additional
loudspeakers.
The M4 can be supplied with NL4 output connectors as an option. Pin
equivalents of EP5 and NL4 connectors are listed in the table below.
