EV-Innovation A New Era for Installed Sound The EV-Innovation (EV-I) family of loudspeakers sees Electro-Voice redefine the stateof-the-art in installed sound once again. EV-I is the result of the largest development program in the history of Electro-Voice.
In the most popular class of loudspeakers for sound reinforcement— compact systems with 12- and 15-inch front-loaded woofers—EVF provides the most coverage patterns (seven) in a physical package offering an unusually high degree of rigging flexibility.
EVF Constant-Directivity Waveguides Electro-Voice developed the first “constant directivity” waveguides in the 1970s, which, unlike conventional devices of the day, maintained their rated coverage angles over a wide frequency range. EV constant directivity meant that anyone seated in the waveguide’s pattern received the same frequency balance as anyone else, a great boon in providing truly uniform coverage and sound quality across a venue.
EVF-1122S and EVF-1152S Medium-Power Series Acoustic Performance Each EVF-1122S loudspeaker is a compact, 12-inch two-way fullrange system. Each loudspeaker contains an SMX2121 12-inch 400-W woofer and one ND2B medium-format, 2-inch-diaphragm, 40-W neodymium high-frequency compression driver on a 12-inchsquare rotatable waveguide.

EVF-1122D and EVF-1152D High-Power Series Acoustic Performance The EVF-1122D and EVF-1152D full-range systems substitute the DH7N large-format, 3-inch-diaphragm, 75-W compression driver and 500-W woofers—DVX3121A 12-inch in the EVF-1122D and DVX3151A 15-inch in EVF-1152D. While the continuous maximum output of the “D” systems is unchanged (see specifications), their dynamic performance is improved.

EVF-1121S, EVF-1151S, and EVF-2121S 12- and 15-Inch Low-Frequency Systems These models are available to augment the low-frequency output ability of the EVF full-range systems. In their passive mode, the EVF-1121S and EVF-1151S have integral low-pass filters that roll off frequencies above 100 Hz at the rate of 12 dB per octave. This means that they can be used without an external digital signal processor (DSP) for crossover from the low-frequency to the full-range systems.

Input Panel, Switch Card and Access Card This new input panel was designed from the installer’s perspective and has a range of innovative, user-friendly features: • Easy-access passive/biamp switch card. • The same interface for the passive/biamp card can be used as an access point to test woofers and drivers without the need to dismantle the enclosure. • Four-pin Phoenix/Euroblock screw-terminal connectors, which accept up to 10-gauge wire (AWG).
The plug-in card system is a unique feature of the EV-Innovation family of loudspeakers. This simple device (EVI-AC) allows diagnostic access to the transducers and protection circuitry inside the enclosure WITHOUT requiring any disassembly or disconnections beyond simple removal and replacement of the plug-in passive/bi-amp switch card. The EVI-AC works with all EVA, EVF and EVH two-way and low-frequency systems with plug-in card.
EVF systems have 22 or more internal rigging points, providing multiple choices for rigging the enclosures. Enclosures may be connected one above another using the supplied EBK-M10-EVI forged-eyebolt kits. However, commonly encountered clusters are more easily fabricated using the accessory HRK and VRK rigging kits. The rigging system is designed to carry a variety of array configurations in vertical or horizontal cluster formats with a safety factor of greater than 8:1.
Rigging Kits for Horizontal Cluster Arrays HRK-1 Horizontal Rigging Kit For typical horizontal clusters using EVF full-range enclosures, with or without EVF low-frequency systems, one HRK-1 kit allows the attachment of two such enclosures side by side. Two rigging kits are required to assemble a three-box cluster. Additional HRK-1 kits can be used to assemble two-over-two and three-over-three clusters (within certain weight and height limitations as outlined in the user manual).
