Stealth Acoustics SA2400 MKII High Current Amplifier with DSP

HIGH-CURRENT AMPLIFIER WITH DSP

The Stealth Acoustics SA2400MKII is a 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 theater applications, the SA2400MKII mounts using the supplied removable rack ears in a standard 19” (482 mm) equipment rack requiring only two RU spaces (3-1/2” – 89 mm), or may stack with other free-standing components. The SA2400MKII delivers a solid 310 watts per-channel into an 8Ω load and 450 watts per-channel into 4Ω.

The SA2400MKII’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). Ver 1.1.3 – Download Here

For maximum flexibility integrating into any audio system, the SA2400MKII includes RCA unbalanced line level, balanced XLR line level, and phoenix speaker level inputs for each channel, all with “pass-through” output connectors. Line level pass through outputs may be programmed as either “pre” or “post” DSP feeds to facilitate extending DSP tuning to additional amplifiers. The speaker level input/pass-through connections allow the SA2400MKII to feed directly from full-range speaker lines, anywhere in the system and will track the speaker’s output level. 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 SA2400MKII amplifier output connections are via 5-way binding posts designed to accept heavy gauge speaker wires.

10 internal, remotely re-callable, read-write presets allow the amplifier to quickly change profile states for different modes of usage, or to load factory speaker optimization curves for Stealth invisible and environmental speakers and subwoofers. Users may store and recall unlimited amplifier profile files via the SSMS App. A selectable automatic turn-on feature activates the amplifier only when audio signals are present, or the 12V trigger function may be utilized to activate and deactivate the amplifier, along with other system components. The IR control functionality also allows for remote control of master volume and preset selection via most 3rd-party control systems. 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. 115VAC through 230VAC 50/60 input line voltages are automatically accommodated via the auto-sensing IEC power inlet. The Stealth Acoustics SA2400MKII amplifier is covered by a 2-Year manufacturer’s warranty.
