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.
