About the Son of Ampzilla II
The Spread Spectrum Technologies Son of Ampzilla II is a stereo solid-state Class AB power amplifier designed by James Bongiorno. It delivers a minimum of 220 watts per channel into 8 ohms and 350 watts per channel into 4 ohms across 20 Hz–20 kHz. The amplifier provides two balanced XLR and two single-ended RCA inputs, with a fully balanced signal path, a 110 dB signal-to-noise ratio, and total harmonic distortion below 0.03%. Its dual-mono power supply uses independent 2 kVA transformers and 100,000 µF of filter capacitance per channel. Thermal protection automatically shuts the amplifier down in the event of excessive temperature. The Son of Ampzilla II measures approximately 9.875 × 17.25 × 5.675 inches and weighs about 40 pounds.
