DF-4 good conditons! (sale only in package of 11)

The new Meyer Sound DF-4 is a medium-throw down fill self-powered loudspeaker system designed for supplementing coverage in systems employing suspended loudspeaker arrays.
It provides even coverage to the areas below and to the front of the arrayed loudspeakers above, with frequency and phase response similar to Meyer Sound loudspeaker components typically used in medium-to-large loudspeaker systems. The self-powered DF-4 produces a maximum peak output of 138 dB SPL (@ 1 meter) within its operating frequency range of 60Hz to 18 kHz.

All aspects of the DF-4 design have been tailored for this specific application. The enclosure shape and the high-frequency horn coverage pattern were carefully selected to ensure that adequate coverage is provided, minimal overlap is maintained and rigging is streamlined. The DF-4 can be incorporated easily into arrays consisting of Meyer Sound’s Type 4 (MSL-4, DS-2P, DS-4P, PSW-2) and Type 6 (MSL-6, MSL-5, PSW-6) self-powered loudspeaker systems. Standard L-Track rigging hardware allows easy integration into QuickFly™ systems, with ring and stud fittings available as an option.

Additionally, the DF-4 works very well in other supplemental fill applications such as under-balcony, effects or surround sound. It also can be used to build small, stand-alone arrays.

The compact, vented enclosure houses a direct  radiating MS-815 15" low frequency driver, and an MS-2001C 4-inch diaphragm compression driver coupled to a symmetrical 50° horn. The amplifier, controller and power supply electronics are integrated into a single, field-replaceable module. The two-channel class AB/H power amplifier employs complementary power MOSFET output stages and produces a total maximum output of 1240 W (620 Wrms/channel).

TruPower limiting technology ensures maximum driver protection, reduces power compression and permits higher constant output for extended periods. The DF-4’s Intelligent AC power supply provides automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Phase-corrected, active processing circuits help maintain excellent performance and reliability, while the high common-mode rejection of the laser-trimmed differential input permits long signal runs through a simple twisted pair cable The DF-4 cabinet is coated with a textured black paint finish (other colors to order) with carpet covering available as an option. The DF-4 is compatible with Meyer Sound’s optional RMS (Remote Monitoring System), which provides comprehensive monitoring of system performance parameters over a Windows™ -based network.
