Meyer Sound MJF-212ATM Manuale Utente

3

The Meyer Sound MJF-212A is a self-powered stage 
monitor designed to meet critical monitoring requirements 
in professional applications. Exhibiting flat amplitude 
and phase responses and exceptional impulse response, 
the MJF-212A meets and exceeds the capabilities of 
conventional stage monitors while offering the simplicity of 
setup and operation provided by self-powered systems.

The MJF-212A monitor’s phase-corrected frequency range 
of 55 Hz to 18 kHz enables accurate reproduction of both 
vocals and instruments with high gain before feedback, and 
provides excellent intelligibility at high output levels with 
low distortion and no coloration added to the signal. The 
MJF-212A is engineered to have exceptional low-frequency 
headroom, which can be helpful in some applications such 
as the extreme low-frequency demands of high-level drum 
monitoring. The face of the low-profile cabinet slopes at 
40 degrees from the stage to permit optimal placement 
relative to the talent, while its medium-Q horn provides even 
coverage in both the horizontal and vertical planes.

The MJF-212A is ideal for high-power monitoring with a 
very low profile for applications that require clear sight lines. 
With its self-powered advantage, the MJF-212A is equally 
suited to touring, rental, and fixed installation applications. 
High power, low profile, and ease of use make it an out-
standing performer in large to medium concerts, as well  
as corporate AV applications and clubs. The MJF-212A  
produces a peak output of 139 dB SPL with exceptionally 
flat phase and frequency response.

The cabinet is constructed from premium birch plywood 
and coated with a durable, textured black finish. It is 
available in custom color finishes, allowing it to blend in 
with any environment. A metal grille lined with acoustical 
black mesh protects the drivers. The rugged MJF-212A 
includes plastic skids on the bottom of the unit to prevent 
damage to the enclosure or stage floor.

 

The MJF-212A monitor and its high-powered drivers were 
designed and manufactured at Meyer Sound’s factory in 
Berkeley, California. 

The low-frequency section features two high-power, 12-inch 
cone drivers with 4-inch voice coils that easily meet the 
power requirements of the system. The proprietary drivers 
employ neodymium magnets for higher efficiency and 
power handling with reduced weight. The lowest frequency 
range is reproduced by these high-power drivers mounted 
in an optimally vented enclosure, working in tandem, and 
each powered by a dedicated amplifier channel. 

The high-frequency section uses a 1.5-inch exit, 4-inch 
diaphragm compression driver with a neodymium magnet, 
also powered by a dedicated amplifier channel. The 
output of the driver is coupled to a symmetrical 50-degree 
constant-directivity horn, which allows the performer to 
experience full bandwidth sound at generous distances 
from the monitor.
