M4 monitor
The M4 is a 2-way high performance stage monitor that produces 134 / 138 dB SPL when driven passively
with the D6 / D12 respectivly or 140 dB SPL when driven actively with the D12. The constant directivity
dispersion of 50° x 70° (h x v) delivers an accurately defined coverage area on stage and when used
upright it is transformed into a powerful PA system with a dispersion suitable for a variety of
applications. The M4 cabinet is constructed from marine plywood, which incorporates the handles,
and has an impact resistant paint finish. It has two M10 threaded inserts on each side panel to
enable quick and flexible rigging and a socket to accept loudspeaker stands. Two runners recessed
in the bottom panel protect the cabinet from scratching and prevent movement.
Amplifiers
The M4 can be driven passively either by d&b's D6 or D12 dual channel power amplifiers configured for
the M4 or actively by the D12 switched to 2-Way Active mode.
More detailed information on specific loudspeaker setups with d&b amplifiers
is available either in the relevant loudspeaker or amplifier manuals.
