Get to know this product.

Intended for whole house audio or home theater bass applications, the SA255 MKII may stack with other components or mount in a standard 19” equipment rack requiring two RU spaces (3-1/2”) with the provided removable rack mount ears. The SA255 MKII delivers a solid 250 watts into an 8Ω load and 350 watts into 4Ω. A variable low pass, 18db per octave filter allows for infinite crossover points from 50Hz to 100Hz.

With a full complement of input and output connectors, the SA255 MKII is easily integrated into any audio system. Inputs include RCA line level, balanced XLR line level, and phoenix connector speaker level, all with pass-through capability. The speaker level input/pass-through connections allow the SA255 MKII to feed directly from full-range speaker lines, anywhere in the system. The SA255 MKII’s amplifier output connection is via a 5-way binding post designed to accept heavy gauge speaker wires. A selectable automatic turn-on feature activates the amplifier only when audio signals are present. Other features include an internal, quiet, 8-stage cooling fan that automatically engages as required.

Front panel controls include volume control, variable low pass filter, phase control, power switch and six power output monitor LED’s. Rear power controls consist of filter bypass switch for full range operation, no signal mute switch and 3-position panel graphics control switch. 115VAC and 230VAC input line voltages are selectable, via a rear panel switch.

The Stealth Acoustics SA255 MKII subwoofer amplifier is covered by a 2-Year manufacturer’s warranty.
