Dreadnaught II

About the Dreadnaught II

The Theta Digital Dreadnaught II is a modular multichannel Class AB power amplifier that accepts between 2 and 10 channels via plug-in modules, typically configured from 5 to 7 channels at 225 watts per channel into 8 ohms with the high-power mono modules. Designed by David Reich (formerly of Classe), it uses fully balanced bridge amplifier modules with both single-ended (RCA) and balanced (XLR) inputs, user-assignable on each module to either the Stereo or Surround bus via rear-panel switches. A front-panel Surround button and rear-panel trigger inputs control standby and surround modes. In the 5x225W configuration it is specified at 225Wpc into 8 ohms, frequency response 0.3 Hz to 250 kHz (-3 dB at full power), signal-to-noise ratio greater than 100 dB (unweighted), and THD+N under 1%, with gain of 31.5 dB balanced and 25.5 dB single-ended. The modular architecture supports high-power 225 W mono modules and lower-power 100 Wpc stereo modules, enabling anything from stereo to 10-channel setups. The heavy, over-built chassis weighs about 98 lb and measures roughly 17.7" (W) x 8.5" (H) x 23.5" (D), featuring Theta's distinctive curved silver faceplate and is widely praised for combining powerful, controlled bass, open highs, and refinement suitable for both music and home-theater systems.
