Powered by eight EL-34 output vacuum tubes in a true dual-mono design, the 34S-1 integrated amplifier delivers monster performance and a dazzling listening experience. As with all Rogers High Fidelity products, this Class A integrated Amplifier boasts superior precision, aerospace engineering and hand-made craftsmanship that presents a new level of realism in audio reproduction.
The ultimate control application easily integrates Apple® iOS® devices with the Rogers High Fidelity Control System to monitor tube status and control all amplifier functions. . .
Made In The USA – All Rogers High Fidelity products are built by hand at our factory in Massachusetts, by technicians with years of experience working to the highest Military and Aerospace specifications. Those rigorous standards ensure that our products will provide decades of pleasure, trouble-free. .
Every unit is individually tested on Audio Precision test gear—the industry standard, and the best there is. Every single amplifier leaves our factory with a detailed test report, providing documentation of perfect performance, and detailing the fanatical lengths we go to in building our amplifiers. .
We want every owner to be satisfied with their unit, from the moment it’s unboxed and plugged in – and for years to come. ..
Transferable Lifetime Limited Warranty – We’re so sure of the quality and durability of our amplifiers, that every unit is guaranteed for life. Not only that, but if you decide to upgrade to another Rogers model, the warranty of your old unit is transferable to the new owner. Our warranty is the platinum standard of the industry, and assures you that your purchase will provide lasting value – forever. ..
Eight EL-34 Tubes – Four output tubes for each channel, with a total of twelve tubes overall, the 34S-1 produces stereo sound from a true dual mono design. ..
Completely Hand Wired – Our amplifiers are assembled and wired by hand at our factory in Massachusetts. Analog sections of our products utilize individual, discrete components—no chips!—and all wiring is point-to-point. These techniques are labor-intensive and far more costly than what you’ll find in throw-away electronics, but ensure a lifetime of reliable performance and serviceability. .
Wiring and soldering of all Rogers products meet Military Standard 2000 requirements—sometimes called “Mil-Spec”. All our assembly technicians are trained and tested on these high standards. ..
Class A Operation – The 34S-1 operates in Class A, which means the output tubes always pass current. This ensures that the power tubes are always operating in their optimal range, and yields the ultimate accuracy in music reproduction..
Control Capability via Bluetooth – You can remotely control all the features of the 34S-1 via connection to an iOS app for your Apple smartphone or tablet. You can choose mode of operation (Ultra-linear or triode), volume, input, and output. Volume, input, and operational mode are also displayed on an LCD screen on the amp.. ..
Dual Power Supply Circuit – Dual linear power supplies can easily handle large dynamic transitions in the audio signal, while maintaining a smooth and clear midrange. Vocals are presented with a truly rich and warm feel. ..
Auto Bias Circuit – What’s “bias”? It doesn’t mean our amps are narrow-minded…just the opposite! Bias is the voltage setting that controls how much current a vacuum tube draws. As tubes age, or as they’re replaced, the bias level will need to change. In most amps, bias setting is done with a meter and a tiny tiny screwdriver that you hope you don’t stick into some place that’ll kill you! .
With Rogers amps, the process of setting or resetting bias is automatic and painless, guaranteeing optimal performance and maximum tube life. If you change the output (power) tubes, or even just one of the set, the amp adjusts without any fuss or action from you. Just another Rogers feature designed to ensure long and hassle-free years of use. ..
Manufacturing Process – We utilize industry-leading Statistical Process Control manufacturing processes that result in greater than 99.8% yield during first pass. That’s better than the safety records of hospitals or the airline industry, and finished products are 100% reliable, fully-tested, and guaranteed for a lifetime. ..
Shipping – We protect our products even after they leave the factory. All our products are shipped in a custom-made double-box container system with die-cut high density and low density foam inserts. Our packaging is designed to withstand a 3 foot drop on any of its 6 sides, with no damage to the amplifier within. We have NEVER had an amplifier returned for shipping damage. NEVER. . .
Aviation Grade Chassis – All our amplifier chassis are made from the same aluminum alloy certified for the construction of commercial and military aircraft. This ensures that each unit will be strong and vibration-resistant for its entire lifetime. No cheap steel chassis. .
Starting with that superb basis, each chassis receives a multiphase powdercoating, topped with a final clear-coat finish. The result is both beautiful, and bulletproof. . Front panels are machined from solid billets of aviation-grade aluminum, and each unit is assembled with Military Standard stainless steel hardware, with each fastener meticulously staked using an aerospace coating. We go to all this trouble to ensure ultimate reliability over a lifetime of use: the coating eliminates hardware failures caused by vibration, movement, or rough handling during shipping. . These are the same procedures developed over many years of manufacturing and assembling satellites: there’s no way to re-tighten hardware in space! . The quality of materials and extreme measures we use guarantee a long product lifetime, regardless of the environment. If our techniques survived space, your listening room simply won’t be a problem! ..
Aerospace Specifications – Every single resistor, capacitor, transformer, and inductor that goes into a Rogers High Fidelity amplifier meets or exceeds military quality standards for parts selection. This ensures that every unit will maintain the same performance documented on our test-bench, for decades to come. .
Our components are the same as those used by NASA in the Space Shuttle and the International Space Station, and by the US Navy in the AEGIS cruisers. ..
Burn-In Process – Given our rigorous standards for all the component parts of our amplifiers, you’d think that we’d never have to worry about failures. It’s true, failures are very, very rare—but we make sure that if the rare failure occurs, it happens before the amp leaves the factory—and then we correct the issue. .
Every single amp we build is “burned-in” at the factory for 100 hours before we even test it. That means it’s run at operating levels—not put in an oven! If resistors or capacitors fail, they generally do so in the first few dozen hours of use, and our 100 hour burn-in makes sure that all components have stabilized, and are ready for test. Following test, it’s ready for you. ..
Power Measurement System – Each amplifier has a tuned, power measurement system that allows for flawless system integration and adjustment. ..
Binding Posts – Rogers amps use the best available parts, including the binding posts used on the 34S-1, which are made by Furutech from oxygen-free (OFC) copper billets, milled, then gold-plated to resist oxidation and provide the best conductivity and contact. Inputs are all gold-plated RCA connectors. ..
Internal Wiring – Wiring is the signal path of any amplifier, and it does make a difference in both durability and performance. We use 18 gauge Military Standard 16878 teflon coated, silver plated copper wire. This is expensive (besides being a mouthful!), but is used in mission-critical applications like the Navy’s AEGIS cruisers. Teflon coating provides heat-protection for decades, where common PVC-coated wire will crack and degrade over time. The 18 gauge wire provides greater signal capability than a trace on a printed circuit board, and ensures that the amplifier will be stable under any condition, and will never limit the dynamic range or transient abilities of your amp. We take such steps to guarantee you the best possible musical performance—for a lifetime.
The 34S-1 provides state of the art noise and distortion performance using all Teflon wiring and mil spec components. As a true dual-mono design, each audio channel is isolated, using a dual power supply design and a dual mono circuit point to point design. Even the most critical of listeners of the 34S-1 will enjoy the finest, organic tube sound quality with stunning three-dimensionality, low-level detail-retrieval and holographic sound staging.
ALL ROGERS HIGH FIDELITY AMPLIFIERS ARE GUARANTEED FOR LIFE!
