Product Description

The JM-1P arrayable loudspeaker combines Meyer Sound’s famed clarity of sound and robust, self-powered performance with our latest breakthroughs in horn design, rigging and loudspeaker control to produce an extremely easy-to-use, highly versatile arrayable loudspeaker system powerful enough to act as a main system, but flexible enough to serve in any number of supporting roles whether horizontal or vertical, flown or stacked.

connector (integrates AC, audio, and network)
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 the 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 dBV (1.0 V rms, 1.4 V peak) continuous is typically the onset of
limiting for noise and music
Input Level:Audio source must be capable of producing +20 dBV (10 V rms,
14 V peak) into 600 Ω in order to produce maximum peak SPL over the
operating bandwidth of the loudspeaker
