how to install Electro-Voice EVF-1122S 99 2-way Speaker

• Plan placement to exploit the 90° x 90° coverage, selecting wall or ceiling mounting locations that maximize intelligibility and even room coverage. Use a rotatable waveguide to align the vertical and horizontal dispersion with seating and stage areas.
• Choose appropriate mounting hardware and enclosure support that meet local codes and the speaker’s weight and dimensions. The gland nut and stainless steel grille assist with secure mounting and durable protection in professional environments.
• Connect to a suitable amplifier or processor, ensuring proper impedance and power matching to achieve the 500 W continuous / 2000 W peak capabilities without distortion.
• Attach the EVF-1122S to the chosen mounting points, orient the cabinet for optimal coverage, and verify rear access for cable routing and ventilation. Use caution to avoid pinching cables or compromising enclosure seals where applicable.
• Configure acoustic alignment by adjusting the waveguide orientation and, if needed, system equalization to achieve uniform coverage across the audience, then perform a sound check to confirm clear speech and balanced music reproduction.
• Perform routine maintenance checks: inspect mounting hardware, grille integrity, and weather sealing if installed in outdoor or semi-exposed environments; clean with a soft, dry cloth and avoid harsh cleaners.
