Meyer Sound M1D-Sub Amplified Line Array Subwoofer

Meyer Sound M1D-Sub Amplified Line Array Subwoofer The M1D-Sub ultra-compact subwoofer complements the M1D ultra-compact curvilinear array loudspeaker by extending bandwidth with its operating frequency range of 32 Hz to 180 Hz and substantially increasing overall system headroom. Because it produces a prodigious peak SPL of 130 dB at 1 meter from a compact cabinet, the M1D-Sub allows system designers to minimize array size while maximizing system response. A variety of QuickFly rigging options allows the M1D-Sub to be flown above, below or within an array, or placed at the base of a ground-stacked array. Although it is intended primarily as a companion subwoofer to the M1D, it is perfectly suited to general use where powerful low frequency augmentation is desired. Features: Extremely compact and lightweight High power-to-size ratio for maximum installation flexibility Exceptional fidelity and peak capability assure clean, high-impact lows QuickFly rigging system simplifies use in flown or ground-stacked arrays Seamless integration with M1D loudspeakers Specifications: Acoustical Operating Frequency Range: 32 Hz - 180 Hz Frequency Response: 35 Hz - 160 Hz ±4 dB Phase Response: 50 Hz - 120 Hz ±45° Maximum Peak SPL: 130 dB Dynamic Ran: >110 dB Coverage Horizontal Coverage: 360° Vertical Coverage: Varies, depending on array length and configuration Transducers Low Frequency Two 10" cone drivers with neodymium magnets Nominal impedance: 4 Ω Voice coil size: 2" Power-handling capability: 400 W (AES) Audio Input Type: Differential, electronically balanced Maximum Common Mode Range: ±15 V DC, clamped to earth for voltage transient protection Connectors: Female XLR input with male XLR loop output Input Impedance: 10 kΩ differential between pins 2 and 3 Wiring: Pin 1: Chassis/earth through 220 kΩ, 1000 pF, 15 V clamp network to provide virtual ground lift at audio frequencies Pin 2: Signal + Pin 3: Signal - Case: Earth ground and chassis DC Blocking: Differential DC blocking up to maximum common mode voltage CMRR: >50 dB, typically 80 dB (50 Hz - 500 Hz) RF Filter: Common mode: 425 kHz Differential mode: 142 kHz TIM Filter: Integral to signal processing (<80 kHz) Nominal Input Sensitivity: 0 dB V (1 V rms, 1.4 V pk) continuous is typically the onset of limiting for noise and music Input Level: Audio source must be capable of producing a minimum of +20 dB V (10 V rms, 14 V pk) into 600 Ω in order to produce maximum peak SPL over the operating bandwidth of the loudspeaker Amplifiers Type: Two-channel complementary MOSFET output stages (class AB/bridged) Output Power: 450 W total THD, IM, TIM: <.02 % Load Capacity: 4 Ω each channel Cooling: Forced air cooling over amplifier heatsink AC Power Connector: PowerCon with looping output Automatic Voltage Selection: Automatic Safety Agency Rated Operating Range: 100 - 240 V AC; 50/60 Hz Turn-on and Turn-off Points: Continuous 90 - 264 V AC; 50/60 Hz Current Draw: Idle Current: 0.41 A rms (115 V AC); 0.33 A rms (230 V AC); 0.42 A rms (100 V AC) Max Long-Term Continuous Current (>10 sec): 3.2 A rms (115 V AC); 1.6 A rms (230 V AC); 3.7 A rms (100 V AC) Burst Current (<1 sec): 5.0 A rms (115 V AC); 2.5 A rms (230 V AC); 5.8 A rms (100 V AC) Ultimate Short-Term Peak Current Draw: 17 A pk (115 V AC); 8.5 A pk (230 V AC); 20 A pk (100 V AC) Inrush Current: 15 A pk (115 V AC); 13 A pk (230 V AC); 15 A pk (100 V AC) RMS Network Equipped for two conductor twisted-pair network, reporting all operating parameters of amplifiers to system operator’s host computer.
