DD Audio SA4.500
The DD Audio SA4.500 is the first Micro Multi-Channel in DD’s new SA (Small Architecture) Series, and it packs 125 watts of continuous, pristine power from each of its four channels at 2 ohm to drive your system with clear, distortion free sound from a micro-chassis. Utilizing rugged MOSFETs, oversized caps, transformers and other high-grade components, these micro-sized pocket rockets are high speed, full range amplifiers.
Key Features
