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.
Frequency Range 30 Hz – 125 Hz
Frequency Response332 Hz – 115 Hz ±4 dB
Phase Response40 Hz – 110 Hz ±30°
Linear Peak SPL4133 dB with crest factor >10 dB (M-noise), 133 dB (Pink noise), 134.5 dB (B-noise)
COVERAGE360° (single unit); varies with number of units and configurations
Low FrequencyOne 18-inch, dual-coil, long-excursion cone driver; 2Ω nominal impedance
TypeDifferential, electronically balancedMaximum Common Mode Range±15 V DC,
clamped to earth for voltage transient protection
Connectors5XLR 5-pin female input with male loop output; XLR 3-pin female connectors available to accommodate only balanced audio (no RMS signals)
Input Impedance10 kΩ differential between pins 2 and 3
WiringPin 1: Chassis/earth through 1 kΩ, 1000 pF, 15 V clamped network to provide virtual ground lift at audio frequencies
Pin 2: Signal +Pin 3: Signal -Pin 4: RMSPin 5: RMS
Case: Earth ground and chassis
Nominal Input Sensitivity6.0 dBV (2.0 V rms) continuous is typically the onset of limiting for noise and music
Input LevelAudio 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 loudspeaker
