The Meyer Sound DS-4P is an arrayable, self-powered mid-bass loudspeaker that provides high power with extremely low distortion.

Developed to supplement the 70 to 200 Hz band in full-range systems, the DS-4P affords additional mid-bass headroom with enhanced directional control. Housing two of Meyer Sound’s rugged 12-inch drivers in a true horn enclosure, the DS-4P provides maximum energy transfer in the mid-bands with minimum frequency response ripple. The DS-4P is most effective when used in multiples within an array and, because it shares the same cabinet “footprint” as the MSL-4, incorporates easily into MSL-4 arrays.

The DS-4P incorporates a two-channel class AB/H power amplifier with complementary power MOSFET output stages and a peak power rating of 1240 watts (620 watts per channel). The integral electronics module also features Meyer Sound’s proprietary phase-corrected active processing circuits and driver protection voltage limiters to ensure exceptional performance and reliability. A laser-trimmed differential input stage affords superior common-mode rejection to allow signal runs using shielded, twisted-pair cable. The integral power supply suppresses high voltage transients and incorporates Meyer Sound’s Intelligent AC system for automatic voltage selection (allowing worry-free worldwide operation), EMI filtering, soft current turn-on and surge suppression.

The DS-4P comes standard with six aircraft pan fittings (ring and stud), with QuickFly rigging optional. The DS-4P is compatible with RMS remote monitoring system.
