Electro-Voice Active Subwoofer SB2A User manual

The new Electro-Voice SB2A powered 12-inch subwoofer eliminates the need
for external system processing and amplification, addressing the demand for
lightweight high performance portable sound systems.
Featuring dual 350 watt amplifiers, the SB2A’s switch-able powered speaker
output can drive either an external 8 ohm passive subwoofer or full range
loudspeaker. This makes SB2A a supremely versatile and compact “sub system
drive” solution, easily configured with a variety of loudspeakers for a multitude of
sound reinforcement applications.
Typical SB2A-powered Electro-Voice system setups include: with a ZX1-90,
as a standalone PA that fits in the front seat of your car; in clusters with Sx100
or Sx300’s; with a passive SB122, for portable lightweight sub extension to
replace bulky 15-inch two-way systems (two 16kg packages vs. one 40kg
package); with an additional powered top box (such as the SxA100+). The
possibilities are endless!
The SB2A shares the same durable injection-molded enclosure as EV’s popular
passive SB122 subwoofer. Both utilize the EVS12S woofer, designed from the
ground up for optimized performance within this small footprint enclosure.
