Ultra efficient and high performance class-D stereo amplifier

Engineered for music lovers, the new Optoma NuForce STA120 stereo power amp provides high quality audio and is neatly enclosed in a striking metal case. Complimenting any contemporary living space, the sleek design and compact dimensions are equally at home displayed as a center piece or can be discreetly hidden.

Precision power

The audiophile power supply and large toroidal transformer provide the power needed to precisely drive almost any speakers to satisfying levels, without adding noise or distortion. Its highly efficient design uses less energy and generates less heat and so provides ultra reliable operation and excellent green credentials.

Compact and elegant

Enclosed in the same elegant anodized aluminum casing as the NuForce range, this exceptionally compact stereo amp is an ideal partner for the DAC80 digital pre-amp and WDC200 wireless DAC.

Custom solutions

With its high power, cool running and compact dimensions, the STA120 is ideally placed to function as an audio distribution amplifier, powering in-wall and in-ceiling passive speakers.

Self-resonant design

The proprietary negative feedback circuitry operates as the cornerstone of this D-class amp’s sound quality. A self-resonant design, the 400 kHz PWM switching frequency constantly adjusts to the input signal, output current demands, and loudspeaker impedance variations. Incredible speed and accuracy ensure that the most explosive dynamics and the minutest of details convey the kind of life-like sound upon which the NuForce reputation rests.
