NuForce STA120 Stereo Amplifier INTRODUCTION NuForce developed the STA120 amplifier for the audio enthusiast as an audiophile-grade stereo power amp housed in an elegant, modestly sized enclosure. Offering quality parts throughout and advanced, high-efficiency switching amplifier operation, the STA120 delivers genuine NuForce performance and value. The STA120's size belies its power: a robust 160 Watts into 4-Ohms per channel. Sharing technology with NuForce's award-winning V3 mono amplifiers, mere power alone doesn't tell the whole story. The STA120 renders all of your recordings with thundering lows, crystalline highs, and a warm, tube-like midrange - all in perfect balance with exquisite resolution and effortless, fatigue-free sound. Proprietary feedback circuitry operates as the cornerstone of the STA120'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 NuForce's reputation rests. To be sure, the STA120 is destined to find its place as the driving force in a great many music and A/V systems. When it comes to mating with décor and today's home audio components, the STA120's power, transparency, modest size and sophisticated appearance defy competition at its modest price point. Where sound and style matter, nothing less will do. Innovative Features • High Power - 1% 125WX2@4Ω / 10% 140WX2@4Ω • Modest size and modern, elegant construction • Proprietary high-speed, negative feedback design • Very high efficiency PWM circuit topology • Available in stylish Silver or Black finish 2

INTRODUCTION
NuForce developed the STA120 amplifier ±or the audio enthusiast as an audiophile-grade stereo power amp
housed in an elegant, modestly sized enclosure. Offering quality parts throughout and advanced, high-e²iciency
switching amplifier operation, the STA120 delivers genuine NuForce per±ormance and value.
The STA120’s size belies its power: a robust 160 Watts into 4³Ohms per channel. Sharing technology with
NuForce’s award-winning V3 mono amplifiers, mere power alone doesn’t tell the whole story. The STA120 renders
all o± your recordings with thundering lows, crystalline highs, and a warm, tube-like midrange - all in per±ect
balance with exquisite resolution and effortless, ±atigue-±ree sound.
Proprietary ±eedback circuitry operates as the cornerstone o± the STA120’s sound quality. A sel±-resonant design,
the 400 kHz PWM switching ±requency 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 o± details convey the kind o± li±e-like sound upon which NuForce’s reputation rests.
To be sure, the STA120 is destined to find its place as the driving ±orce in a great many music and A/V systems.
When it comes to mating with décor and today’s home audio components, the STA120’s power, transparency,
modest size and sophisticated appearance de±y competition at its modest price point. Where sound and style
matter, nothing less will do.
