SA2400-MKII High-Current DSP Amplifier

The SA2400-MKII is a 2-rack-unit high-current amplifier with built-in DSP, engineered to drive Stealth invisible speakers, subwoofers and full home-theater systems. It delivers 310 watts per channel into 8 ohm and 450 watts per channel into 4 ohm with vanishingly low distortion, providing the clean headroom required to extract every drop of performance from Stealth's flat-diaphragm loudspeakers.

  • 310 W / channel into 8 ohm, 450 W / channel into 4 ohm

  • 20 Hz to 50 kHz frequency response (+1 / -3 dB)

  • Total Harmonic Distortion below 0.05% at 460 W / 4 ohm

  • Signal-to-noise ratio greater than 105 dB (A-weighted)

  • Crosstalk greater than 85 dB; 36 dB maximum voltage gain into 8 ohm

  • 2 RU rack-mount chassis, 19 in W x 15-3/4 in D x 3-1/2 in H

Onboard DSP allows the installer to tailor crossovers, EQ and protection for any Stealth speaker pairing in residential or commercial deployments.
