Stealth Acoustics’ new SA255 is a 350W monaural (mono) amplifier with a variable low-pass filter and clean power at 4 ohm loads. The filter stage can be bypassed to allow for full range mono-brick operation. Built on a high-current class A/B amplifier platform from the previous 255R model, the new SA255 includes Stealth’s “Cool-Blue” back-lit front panel graphics.

In addition to a built-in limiter stage to help resist overloads and tighten up bass response, the SA255 features a wide array of input integration options — balanced XLR inputs, unbalanced RCA line- level inputs and speaker level inputs, all with pass-through outputs are provided for maximum flexibility in integrating the amplifier to a wide variety of sources. A no-signal auto mute function turns the amplifier off for energy conservation when audio signals are not present and immediately turns the amplifier on automatically upon resumption of source content.

Here are the detailed specs.
