General Description:
The Electro-Voice EVF-1122D/64 is a high-power, two-way loudspeaker system that can be used in a variety of applications where
high-quality sound reinforcement is required in a compact, lightweight package.
The EVF-1122D/64 utilizes the DH7N, a high-output 3” titanium
compression driver, coupled to a Constant Directivity™ 60° x 40°
waveguide. The DVX3121A 12” woofer was developed using FEA
optimization for motor, suspension, and electrical design to ensure
very low distortion, high efficiency, and maximum intelligibility at high
SPL. The crossover uses steep, 24-dB-per-octave slopes with equalization for very smooth response in the vocal range, linear off-axis
response, and a protection circuit for long-term reliability.
The EVF-1122D/64’s features make it ideal for many fixed-install
applications. The trapezoidal enclosure is constructed of weatherresistant birch, and coated with EVCoatTM for maximum protection
from the elements. The unique acoustic and rigging design allows
for vertical and horizontal clusters to be built using any combination of loudspeakers from the entire EVF and EVH series. With
seven horn patterns to choose from, along with an assortment of
low-frequency and subwoofer loudspeakers, you have the tools to
maximize flexibility of system design, no matter what the application
and budget. The innovative input panel provides a choice of Phoenixstyle connector (included in all standard models) or the ability to add
a dual NL4-type connector cover plate or gland-nut cover plate (for
weatherizing applications). An externally accessible jumper selects
passive or active operation. An available 70.7/100-V transformer
kit may be easily mounted to the input panel for use in distributed
systems. All these features give you the flexibility to address a large
range of venues, quickly and precisely supporting customer requirements with fewer items in inventory.
