This compact stereo receiver achieves both a sound quality and SPL output that belies its small size. Designed around a Bi-Phase PWM (Pulse-Width Modulation) digital amplifier circuit, the Amp Box achieves a remarkable 80% operational efficiency and a highly dynamic 30 watts per channel output into 4 ohms. The shielded metal chassis protects the circuitry from vibration and electromagnetic interference for the highest fidelity possible.
