Stealth Acoustics SA2400-MKII 2-Channel, High-Current Amplifier with DSP

The Stealth Acoustics SA2400 is high-current two-channel amplifier with powerful built-in digital signal processing functions suitable as a low distortion power source for Stealth Acoustics speakers, Stealth subwoofers, or other un-powered speakers and subwoofers. Intended for distributed audio, fixed installations, or home theatre applications, the SA2400 mounts using the supplied removable rack ears in a standard 19" (482 mm) equipment rack requiring only two RU spaces (3½" - 89 mm), or may stack with other free-standing components. The SA2400 delivers a solid 310 watts per channel into an 8Ω load and 450 watts per channel into 4Ω.

The SA2400’s internal DSP functions may be programmed for each channel independently or together and include 11 bands of fully-parametric EQ, variable High and Low Pass filters with selectable slopes, fully programmable limiter stage and delay functions. All parameters may be programmed using front panel controls or via a USB connected computer utilizing Stealth Signal Management System software (SSMS).

For maximum flexibility integrating into any audio system, the SA2400 includes RCA unbalanced line level, balanced XLR line level, and phoenix speaker level inputs for each channel, all with “pass-through” output connectors. The speaker level input/pass-through connections allow the SA2400 to feed directly from full-range speaker lines, anywhere in the system. A stereo optical input is provided for connecting digital sources to the amplifier. Inputs may be mapped to either channel and may be “mono-summed” via programming. The SA2400 amplifier output connections are via 5-way binding posts designed to accept heavy gauge speaker wires.

A selectable automatic turn-on feature activates the amplifier only when audio signals are present. Quiet 8-stage cooling fans automatically engage as required. The front panel includes direct master volume and menu access controls as well as an LCD display window and dual clip indicators. Rear panel controls include a no signal mute switch, ground lift switch, and power switch. Input line voltage is auto-sensed/selected and supports 115VAC and 230VAC.
