Features of the Meyer Sound DF-4
- Optimized specifically for downfill applications
- Ideally matched in performance to the MSL-4 and MSL-6
- Extremely smooth transition to main array coverage
- Easily integrated and optimized for fast setup
The Meyer Sound DF-4 is a medium-throw downfill loudspeaker designed for
supplementing coverage in flown sound reinforcement systems.
It provides even coverage to the areas below and to the immediate
front of arrayed loudspeakers, and exhibits frequency and phase
response similar to other Meyer Sound loudspeakers that are
typically used in medium-to-large arrays. The enclosure shape
and the high-frequency horn coverage pattern are carefully selected
to ensure adequate coverage, minimize overlap and streamline
rigging procedures.
The compact, vented DF-4 enclosure houses a direct-radiating
15-inch low-frequency driver, and a 4-inch diaphragm compression
driver coupled to a symmetrical 50° horn. The two-channel
class AB/H power amplifier employs complementary power MOSFET
output stages and produces a total burst output of 1240 watts
(620 watts per channel). The integrated, field-replaceable amplifier
and control unit is equipped with TruPower limiting technology,
and the power supply incorporates Intelligent AC for fail-safe
international operation. Phase-corrected, active signal processing
circuits help maintain excellent performance and reliability,
while the high input CMRR permits long signal runs over shielded
twisted-pair cable.
The DF-4 cabinet is coated with a textured black finish. The
DF-4 is compatible with Meyer Sound's RMS remote monitoring
system, which provides monitoring of system performance over
a Windows-based network.
