STR Features & Functions
Two-Channel Nirvana.
More power, more control, more connections, more technology. The STR Integrated Amplifier will change your perception of two-channel amplification. Now, you can have it all, in one component, with the kind of superior response and realism that Anthem is famous for.
More Subwoofer Options
STR Integrated Amplifier gives you more options for subwoofer configuration. Use one subwoofer or two for both channels, or two independent right-and-left channel specific subwoofers. The bass management in conjunction with ARC® is uniquely engineered engineered for seamless subwoofer blending, achieving an incredibly accurate and lifelike performance.
More Attention to Detail
We believe that two-channel listening demands attention to detail. A component must balance extreme power and delicate transparency, with flawless signal integrity being the benchmark of stereo performance. To that ultimate end, the Anthem STR Integrated Amplifier is designed with the shortest possible signal paths, and differential analog to digital circuitry to cancel artifacts and keep noise to a minimum.
More Power, From Oversized Toroidal Transformers
Clarity is maintained using carefully selected components, many of them engineered exclusively in-house at Anthem, like the huge, precision-wound toroidal transformers and their matching oversized filter capacitors. This massive power supply operates in harmony with the high-current, high-output amplifier section to produce an astounding 550W per channel continuously into 2 ohms! Peak production is effortless and instantaneous, cinching even the most challenging material. The use of multiple bipolar output devices dramatically reduces distortion while ensuring extreme linearity, extensive bandwidth, and stress-free reliability.
Moving Magnet and Moving Coil Cartridges
Anthem has also taken into consideration the resurgent popularity of vinyl long-playing records, and has included separate inputs for moving magnet and moving coil cartridges, with the phono section completely shielded to maintain signal purity. The transparency and refinement of the STR Integrated Amplifier reveals the hidden magic of classic media.
More Innovative Electronics
No less important is Anthem’s non-invasive Advanced Load Monitoring (ALM) circuitry, which protects the output section of the STR Integrated Amplifier by constantly monitoring temperature, current and voltage to ensure optimum long-term performance.
And there’s more. The STR Integrated Amplifier has more useful features than the average integrated amp, with no filler. Everything is geared toward giving you the power and control you need to achieve two-channel nirvana.
Aside from its cutting-edge technology and Anthem-exclusive innovations, one look tells you that the STR is a different amplifier animal altogether. The large Thin Film Transistor (TFT) display on the front panel can be seen from across the room, and gives you surprisingly easy control over your whole system. It’s a part of the luxurious new industrial design of the STR Integrated Amplifier, a striking look that’s available in two beautiful finishes, Black or Silver.
