2. Meyer Sound DS-2P – Self-Powered Arrayable Mid-Bass

The DS-2P is a folded-horn mid-bass designed to supplement MSL-4 in the 40-160 Hz range, or work with MSL-3A, MSL-10A, 650-P subs. Always used in minimum pairs.

Electronics / Amp:

• Same MP-2 amplifier: 1240W (620W/ch)
• TruPower Limiting, Intelligent AC auto-select, low power compression <1dB vs 3-6dB conventional
• Optional RMS

Physical / Rigging:

• Weight: 221 lb (100 kg)
• Dimensions: Approx 30.00″ W x 30.26″ H x 21.97″ D, trapezoidal 7.5° angle for arrays
• Rigging: 6 rigging brackets (3 top / 3 bottom), interchangeable: aircraft pan fittings, 3/8″-16 nut plates, M10 x 1.5 nut plates, blank. Max recommended load 600 lb (273 kg) per cabinet with 5:1 safety
• Weather protection available with rain hood and protective treatment
• Crossover use: Designed to work with LD-1A / LD-2: 80Hz switch splits signal – below 80Hz to Sub output (650-P), above 80Hz to DS-2P

3. Meyer Sound LD-2 – Line Driver / Processor

Compact alternative to the larger LD-1A. A 1U line driver for integrating different Meyer self-powered loudspeakers into a complete system. Drives cable runs up to 1000 feet without instability or distortion.

Architecture:

• 2-channel device, 1 input per channel (Left/Right), 3 outputs per channel
• Outputs per channel: Mid-Hi, Mid-Bass/AUX, Sub

Controls per channel:

• Gain: -12 to +6 dB for each output section and master
• Mute: Individual Mute switch with LED for each output + Master Mute
• Mid-Hi Section: Array EQ filter -6dB at 220Hz, 0.6 octave bandwidth to correct low-mid rise from 3-5 MSL-4 array + Low Cut 160Hz, 12dB/oct, Q=0.8
• Mid-Bass/AUX: Low Cut 160Hz 12dB/oct + Polarity switch (0° / 180°)
• Sub: Polarity switch
• Crossover Switch: Mid-Bass & Sub Crossover at 80Hz – with switch in, divides at 80Hz between Mid-Bass and Sub outputs; switch out sends full-range to both
• Master: Gain, Mute, Signal presence / Clip LED
