1100-LFC Low-Frequency Control Element

1100-LFC Low-Frequency Control Element

The 1100-LFC low-frequency control element is a self-powered loudspeaker defined by its sonic linearity in reproducing low-frequency transients at high, continuous levels with very low distortion. This ultra low distortion, coupled with exceptional headroom and optimized rigging options, makes the 1100-LFC a flexible tool for low-end directional applications for large-scale tours and installations. 

FEATURES AND BENEFITS

  • High peak power output yields excellent transient reproduction and low-frequency clarity at extreme operating levels
  • Tuned, vented cabinet optimized for low air velocities
  • Linearity and power bring new possibilities for low-frequency system design
  • Stackable and flyable with other 1100-LFCs in regular and cardioid arrays
  • Optimized to integrate with MILO, MICA, JM-1P, and other Meyer Sound loudspeakers

APPLICATIONS

  • Stadiums
  • Arenas
  • Concert halls
  • High-power, controlled-directivity arrays

Specification
  • The loudspeaker shall be a linear, low-distortion, self-powered, low‑frequency control element and shall be capable of flown and ground stacked configurations. Its transducers shall include two 18 in long‑excursion cone drivers.

    The loudspeaker shall incorporate internal processing and a 2-channel Class AB/H amplifier with complementary MOSFET output stages. Protection circuits shall include TruPower limiting. The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal 0 dBV (1.0 V rms) signal (+20 dBV to produce maximum peak SPL).

    Audio connectors shall be 5-pin XLR, female and male; 3-pin XLR audio connectors shall be optionally available.

    Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: operating frequency range shall be 28–100  Hz; frequency response shall be 30–85  Hz ±4  dB (measured in half-space with pink noise at 4 m, 1/3-octave frequency resolution); phase response shall be 34–82 Hz ±30 degrees; Linear Peak SPL shall be 140 dB, measured in half‑space with M-noise at 4 m referred to 1 m.

    The internal power supply shall perform EMI filtering, soft current turn-on, and surge suppression. Power requirements shall be nominal 230 V AC line current at 50 or 60 Hz. UL and CE operating voltage range shall be 208 to 235 V AC. Current draw during burst shall be 18 A rms at 230 V AC. Current inrush during soft turn-on shall not exceed 30  A at 230  V  AC. The AC power connector shall be a PowerCon32. The loudspeaker shall include the RMS remote monitoring system module.

    Components shall be mounted in an optimally tuned, vented enclosure constructed of premium multi-ply birch and coated with a slightly textured black finish.

    Dimensions shall be 52.60 in (1336 mm) wide x 20.48 in (520 mm) high x 33.00 in (838 mm) deep. Dimension with optional rigging shall be 54.65 in (1388 mm)  wide x 20.48 in (520 mm )  high x  33.00 in (838 mm)  deep. Weight shall be 249  lb  (112.9  kg). Weight with optional rigging shall be 285 lb (129.3 kg).

    The loudspeaker shall be the Meyer Sound 1100-LFC
