The revolutionary STR Preamplifier is a new type of audio component that gives you more control and more refinements, including more connection options and more advanced technology, in a single, easy-to-use component.
Designed, engineered, and Crafted in Canada, the STR Preamplifier combines the benefits of an advanced preamp with the power of a processor, as well as functions like leading-edge DAC, onboard Anthem Room Correction (ARC®®), customizable bass manager for mono or stereo sub outs, MM and MC phono inputs—far more than the average preamplifier.
And it includes new generations of many of Anthem’s award-winning, audiophile-loving, review-praised digital signal processing innovations, delivering a noticeably higher level of audio performance realism.
The new STR Preamplifier drives all of your entertainment options today, and tomorrow.
More Subwoofer Options
The STR Preamplifier 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 for seamless subwoofer blending, achieving incredibly accurate and lifelike performance.
Home Theatre Bypass
The concept of combining a stereo preamplifier with a home theater system is taken to a whole new level. The STR Preamplifier supports two subwoofer channels in addition to the two fronts. XLR as well as RCA connection is provided for all channels, and HT Bypass mode engages while the preamp is on standby. This way, you don’t have to turn it on when watching movies. To allow the purest signal path, relays are employed to hard-wire the input jacks to the outputs — the STR Preamplifier essentially becomes a straight wire.
Moving Coil and Moving Magnet Phono
Anthem has also taken into consideration the resurgent popularity of vinyl records, and has included separate inputs for moving magnet and moving coil cartridges, with the phono section completely shielded to maintain a clean signal. The transparency and refinement of the STR Preamplifier reveals the hidden magic of classic media. In addition, the phono curve is continuously adjustable for proper playback of any record that predates the RIAA equalisation standard.
Premium Components
Clarity is maintained using carefully selected components, many of them engineered exclusively in-house at Anthem. We believe that two-channel listening demands attention to detail, with flawless signal integrity being the benchmark of stereo performance. To that ultimate end, the Anthem STR Preamplifier is designed with the shortest possible signal paths, and differential analog to digital circuitry to cancel artifacts and keep noise to a minimum.
