Product Description for the Electro-Voice EVOLVE 50 

Production Description for  Electro-Voice EVOLVE50 Column Speaker Array With Subwoofer 

The EVOLVE 50 Portable Column System is a three component loudspeaker system powered by a 1000 W Class-D amplifier and driven by Electro-Voice's QuickSmartDSP. 

The system consists of a 15 mm wooden, ported, powered subwoofer enclosure that houses a 12” subwoofer capable of a functional frequency output down to 37 Hz. 

The bi-directional aluminum pole’s connection to the subwoofer is secured using a magnet, and the column array is gravity-held to the sub pole. The signal is internally routed to the components. 

Eight 3.5"" neodymium drivers in the column array coupled with the 12"" subwoofer deliver up to 127 dB SPL. The eight composite waveguides control high frequencies with 120° of horizontal coverage, and 40° of asymmetrical (down-facing) vertical coverage to ensure suitable output for sitting and standing audiences. The sub pole and column array come prepackaged in a carrying bag. 

The processing engine allows for easy setup via four presets (Music, Live, Speech, and Club), three-band EQ, five user-programmable presets (Store and Recall settings), output delay, phantom power (+15V), visual monitoring of limiter status, input level control and meters, and master volume control to ensure optimal gain structure. 

The new Electro-Voice QuickSmart Mobile application utilizes Bluetooth Low Energy (BTLE) technology for the wireless configuration, control, and monitoring of up to six EVOLVE 50 systems simultaneously. High-resolution Bluetooth audio streaming adds convenience for wireless music playback in breakout rooms, intermission, and musical accompaniment. 

Designed to deliver an uncompromising combination of lightweight, low-profile looks, and superior Electro-Voice audio quality, the EVOLVE 50 sets a new performance standard for powered column systems. 

The perfect choice for DJs, mobile entertainers, bands, singer/songwriters, and any venue where a high-output portable sound is needed – no other column system currently available sounds as good, looks as good or is as easy to use. The smooth clarity of the EV sound in a sleek new form factor.
