92 Hz – 18 kHz ±30 degrees
133.5 dB (M-noise), 130 dB (Pink Noise), 134.5 dB (B-noise)
Note: Linear Peak SPL is measured in free-field at 4 m referred to 1 m. Loudspeaker SPL
compression measured with M-noise at the onset of limiting, 2-hour duration, and 50-
degree C ambient temperature is <2 dB.
M-noise is a full bandwidth (10 Hz–22.5 kHz) test signal developed by Meyer Sound to
better measure the loudspeaker's music performance. It has a constant instantaneous
peak level in octave bands, a crest factor that increases with frequency, and a full band-
width Peak to RMS ratio of 18 dB.
Pink noise is a full bandwidth test signal with Peak to RMS ratio of 12.5 dB.
B-noise is a Meyer Sound test signal used to ensure measurements reflect system
behavior when reproducing the most common input spectrum, and to verify there is still
headroom over pink noise.
110°
Varies, depending on array length and configuration
Two 9 in long-excursion cone drivers; 2 Ω nominal impedance
One 3 in compression driver coupled to a constant-directivity horn through a patented
®
REM manifold; 4 Ω nominal impedance.
Differential, electronically balanced
XLR 5-pin female with male loop output; XLR 3-pin female connectors available to
accommodate only balanced audio (no RMS signals)
10 kΩ differential between pins 2 and 3
Pin 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: RMS (polarity insensitive)
Pin 5: RMS (polarity insensitive)
Case: Earth ground and chassis
Note: Pins 4 and 5 (RMS) included only with XLR 5-pin connector that accommodates
both balanced audio and RMS signals.
6.0 dBV (2.0 V rms) continuous is typically the onset of limiting for noise and music
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 loudspeaker
