Stealth Acoustics Monaural Subwoofer Amplifier 255R

255R Monaural Subwoofer Amplifier

The Stealth Acoustics 255R is an integrated monaural subwoofer amplifier / crossover system designed as a low distortion power source for Stealth Acoustics wall or ceiling mounted, invisible subwoofer panels or other un-powered subwoofer speakers. Intended for whole house audio or home theater bass applications, the 255R may stack with other components or mount in a standard 19” equipment rack requiring only two RU spaces (3-1/2”). Removable rack mount ears are provided. The 255R delivers a solid 250 watts into an 8? load and 350 watts into 4?. 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 255R is easily integrated into any audio system. Inputs include RCA line level, balanced XLR line level, and 5-way binding post speaker level, all with pass-through capability. The speaker level input/pass-through connections allow the 255R to feed directly from full-range speaker lines, anywhere in the system. The 255R’s amplifier output connection is via a 5-way binding post designed to accept heavy guage 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, low pass filter on/off switch, phase control, power switch and six power output monitor LED’s. 110VAC and 220VAC input line voltages are selectable, via a rear panel switch.

The Stealth Acoustics 255R subwoofer amplifier is covered by a 2-Year manufacturer’s warranty.
