Meyer Sound 900-LFC Compact Low-Frequency Control Element

Meyer Sound’s 900-LFC compact low-frequency control element reproduces low frequencies at high continuous output levels with extremely low distortion. The 900-LFC offers the same sonic linearity as Meyer Sound’s 1100-LFC low-frequency control element in a smaller, lighter cabinet, making it ideal for building scalable systems to suit touring applications or fixed installations of any size.\n\nFeatures:\nCompact cabinet with small footprint and extraordinary power-to-size ratio\nHigh peak power output with extremely low distortion\nExceptional linearity, transient reproduction, and low-frequency clarity\nSelf-powered for simplified setup and increased reliability\nStackable and flyable in regular and cardioid arrays, with tilt and splay options\nIntegral pole-mount receptacle easily pairs the subwoofer with ULTRA Series loudspeakers\nSpecifications:\nAcoustical:\nOperating Frequency Range: 31 Hz – 125 Hz\nFrequency Response: 32 Hz – 115 Hz ±4 dB\nPhase Response: 40 Hz – 110 Hz ±30°\nLinear Peak SPL: 133 dB with crest factor >10 dB (M-noise), 133 dB (Pink noise), 134.5 dB (B-noise)\nCoverage: 360° (single unit); varies with number of units and configurations\nTransducers:\nLow Frequency: One 18-inch, dual-coil, long-excursion cone driver; 2Ω nominal impedance\nAudio Input:\nType: Differential, electronically balanced\nMaximum Common Mode Range: ±15 V DC, clamped to earth for voltage transient protection\nConnectors: XLR 5-pin female input with male loop output\nInput Impedance: 10 kΩ differential between pins 2 and 3\nWiring:\nPin 1: Chassis/earth through 1 kΩ, 1000 pF, 15 V clamped network to provide virtual ground lift at audio frequenciess\nPin 2: Signal +\nPin 3: Signal -\nPin 4: RMS\nPin 5: RMS\nCase: Earth ground and chassis\nNominal Input Sensitivity: 6.0 dBV (2.0 V rms) continuous is typically the onset of limiting for noise and music\nInput Level: Audio source must be capable of producing +20 dBV (10 V rms) into 600 Ω to produce the maximum peak SPL over the operating bandwidth of the loudspeakerr\nAmplifier:\nType: Two-channel, open-loop, class D\nTotal Output Power: 3100 W peak\nTHD, IM, TIM: < 0.02%\nCooling: Convection\nAC Power:\nConnectors: powerCON 20 input with loop output\nAutomatic Voltage Selection: 90–265 V AC; 50–60 Hz\nSafety Rated Voltage Range: 100–240 V AC, 50–60 Hz\nTurn-on and Turn-off Points: Turn-on: 90 V AC; Turn-off: none; internal fuse protection above 265 V AC\nCurrent Draw:\nIdle : 0.60 A rms (115 V AC), 0.49 A rms (230 V AC), 0.63 A rms (100 V AC)\nMaximum Long-Term Continuous Current (>10 sec): 4.9 A rms (115 V AC); 2.5 A rms (230 V AC); 5.2 A rms (100 V AC)\nBurst Current (<1 sec): 8.8 A rms (115 V AC), 4.7 A rms (230 V AC), 11.0 A rms (100 V AC)\nMaximum Instantaneous Peak Current: 18.2 A peak (115 V AC), 9.2 A peak (230 V AC), 20.6 A peak (100 V AC)\nInrush Current: < 20.0 A peak\nRMS Network(Optional): Equipped with two-conductor twisted-pair network, reporting all operating parameters of amplifiers to system operator’s host computer.\nPhysical:\nDimensions without Rigging: W: 27.43 in (697 mm) x H: 24.43 in (621 mm) x D: 24.89 in (632 mm)\nWeight without Rigging: 136 lb (61.7 kg)\nEnclosure: Premium multi-ply birch with slightly textured black finish\nProtective Grille: Powder-coated, hex-stamped steel with acoustical black mesh\nRigging: Optional end frames with captive GuideALinks secured with 0.3125 in x 0.63 in quick release pins that allow 0°, 1.25°, 2.5°, 3.75°, or 5° splay angles; detachable side handles.
