NO EXCEPTIONS. The products you are about to discover in these pages – DVD and CD players, preamplifiers, surround sound processors, power amplifiers, receivers and more – are unique. They come from a high performance home theatre and high fidelity components. We use the word manufacture advisedly. We make everything from core components to complete products ourselves. In our own factories. Under our own control. Is this important? Extremely. Among other things, this integration gives us the opportunity to select everything that goes into a Rotel product. Even down to what we call board level parts – the semiconductors and passive circuit elements that distinguish merely competent designs from extraordinary ones. This is an essential part of our Balanced Design Concept. Balanced Design Concept is a disciplined synthesis of physics, electronics and mechanical engineering, guided by our firm belief that the best need not be the most costly. Balanced Design begins with basic circuits conceived by an international team of award-winning engineers. It includes an exhaustive evaluation of every part used in these circuits to determine not just which one will do... but which one will do best. Balanced Design also means that we verify every choice we make with the most critical and sensitive laboratory instrument available anywhere --- the human ear. Thats why our team of trained critical listeners evaluate every prototype, and then collaborate in fine-tuning basic designs until they fully meet Rotels demanding standards. Balanced Design combines both hard science and experienced intuition to bring you closer to the source…any source, be it music or movies…and to let you hear without compromise exactly what the artists intended you to hear. Nothing more. And certainly nothing less.

5 Of all audio components, the amplifier has arguably the toughest job. It must provide a common interface for a diverse range of source products, including CD, DVD-A, SACD players and MM/MC phono cartridges. On the other side of the divide, the amplifier is also forced to wrestle with the unpredictable demands of a loudspeaker. In some instanc- es, the two roles are seemingly incompat- ible, as the amplifier caresses millivolt source signals while delivering many tens of volts and, potentially, as many amperes of current to maintain a rock solid power output. The success of this balancing act depends largely on power supply design and circuit layout, especially the ground plane. It is our custom-built transformers, multiple supply regulators and symmetrical topologies of all Rotel amplifiers that provide the foundation of a performance thats realised in our high- current, complementary power amp stages. Our published specifications are very con-ser- vative, and reflect a maximum continuous power output that the amplifier will comfor- tably maintain. In reality, of course, loud- spe- akers do not behave like the 8 ohm or 4 ohm test loads used for measurement. They comprise reactive (capacitive and inductive) elements that force the voltage and current to become out of step as the impedance swings as high as 50 ohms or more before plunging to 2 ohms, or even less, at differ- ent frequencies. This ability to grapple with almost any speaker load, no matter how difficult, sets Rotel amplifiers apart from the mainstream.Furthermore, real music is quite unlike the steady state tones typically used for mea- surement purposes. Music is dynamic, a mix of chords, crescendos and instrumental transients that may peak for just a few mil- liseconds. Once again, Rotel amplifiers are designed to accommodate these peaks, delivering huge increases in clean power well beyond their rated specification. Take the RB-1050 as an example. Modestly rated at 70W/8 ohm, it will actually deliver 125W under dynamic, music-like conditions, increasing to 225W, 375W and 470W into tougher 4, 2 and 1 ohm loads. This is an exceptional performance for a mere 70W amplifier and helps explain why our amplifi- ers typically sound louder and more dynamic than competing products with a notionally similar specification. But high dynamic power, and therefore high dynamic current, is of little benefit without great linearity. Many manufacturers claim bold figures for peak or instantaneous cur- rent without specifying the duration of the peak or how distorted the signal. After all, an amplifier that can deliver 20A of current at <1% distortion cannot fairly be compared to another that suffers 10% or more at the same output. Our RB-1050 will deliver 470W/1ohm with 10msec peaks at less than 1% distortion, thats nearly 22A of clean current from our least powerful model! Rotel amplifiers: high value audio engineer- ing designed to tackle the real world, not just the lab bench. You will no doubt notice that we spend a lot of time in this brochure describ- ing Rotels approach to power supply design. Heres why. A power supply is the heart of any home entertainment component. It pumps, if you will, proper amounts of current at just the right voltage so that all the active circuits in your amplifier, DVD player, surround sound processor, etc., can do the job they were designed to do. Power supplies arent black magic. Theyre comparatively simple to design, but good ones, however, are costly. Thats why few manufacturers describe theirs – an accurate picture might be more embarrassing than enlightening. At Rotel, we take the opposite approach. We talk about our power supplies because weve already done our homework and built the manufacturing infrastructure we need. For example, we design and manufacture our own transformers in-house. Why? Because a transformer, that critical transition between AC power from the mains and the rest of your component, must have enough current capability to satisfy your components active circuitry. And it must accurately step down the mains voltage to levels that are useable by subsequent circuit stages. Making our own transformers gives us a three-fold advantage over the com- petition. First, we dont need to shop for a good enough product made by someone else. Second, we can schedule production so that the right transformer is available just as the component it was designed for is ready to receive it. Lastly, we dont have to factor in some other companys profit mar- gin when we price our products. Given that the transformer is often the single most expensive part of a component, thats an enormous advantage. For one thing, it means we can use higher quality capacitors – BHC Slit Foils, Aerovox T-Networks, for example – to store and provide the instantaneous current deli- very that improves a Rotel components ability to deliver the full dynamics of even the most demanding music selection or soundtrack. Rotel products simply reproduce sound with greater fidelity to what we know is real. Of course, there are other parts to a power supply – rectifiers and voltage regulators, to name but two. These are chosen and configured with the same meticulous care we lavish on any other part of a Rotel component. So the next time someone doesnt describe a power supply properly, you can ask yourself What are they hiding? Or, you can simply buy a Rotel.

Tuner, High Resolution CD Player, Stereo Integrated Amplifiers 23 RA-1062 Hi Fi Choice, August 2003 If they dont know it yet, then Rotels RA-1062 is an amp that its peers will grow to hate. It is solidly and reliably constructed, offers a generous assortment of features and delivers a powerful, purposeful and crisp sound that pushes all the emotive buttons. All this and more, but at a price that represents a slap in the face to its competition. The RT-1080 AM/FM tuner is the perfect RF sour- ce for a custom-installed system, thanks to a bi- directional RS-232 computer-style interface, dual antenna inputs, and total remote control capability. Sound quality comes from the same attention to detail that distinguishes every Rotel: custom- wound transformers, high grade power supply parts, refined audio circuits carefully designed to reveal all the subtleties FM broadcasts can bring. The RT-1080 also includes RDS (Radio Data System) enhancements to make FM broadcast- ing even more enjoyable.* RDS lets you see your favorite stations call letters, for example, and the type of program material theyre broadcasting. Thirty (30) direct access presets allow you to pro- gram your favorite stations for quick recall. A vari- ety of tuning modes and built-in compensation for US and European FM broadcast standards make this tuner truly universal. * RDS functions determined by your local radio stations. The RCD-1072 proves conclusively that cost-con- scious high performance in a single disc CD player is still available – and still outperforming many so- called audiophile DVD players. Utilising circuit configurations originally developed for Rotels reference class components, this afford- able unit redefines your sonic expectations. The segmented power supply features a large toroidal transformer for minimal power supply sag as well as reduced hum emissions. High quality rectifiers, tight tolerance voltage regulation and low-ESR storage capacitors make sure that all circuits always operate as their designers intended. The critical analogue stage uses meticulously selected parts in a minimalist circuit environment to ensu- re the finest sound quality. The RCD-1072 uses the same over-scan disc mechanism once reserved only for premium priced players. The remarkable new Burr-Brown PCM- 1732 IC provides advanced digital filtration, HDCD decoding, and precise D/A conversion. A coaxial digital output supplements the high current analo- gue outputs. A high-density FL display, complete programming capability, remote control, and a 12 volt trigger complete the picture. The RA-1062 is the evolution of Rotels highlyregarded RA-1060. The design team spent hun- dreds of hours evaluating individual component performance from input to output. Chief among these improvements is the UK designed and manu- factured T-Network power supply capacitor. These premium grade components follow the tradition of our Slit Foil capacitors by incorporating tiny perfora- tions in the capacitor foil to reduce distortion. Even more significantly, the T-Network capacitor has multiple connections that effectively create several smaller capacitors within a single larger body and thus ensure far lower voltage intermodu- lation between input and output. The result is a striking portrayal of musical subtle- ties supported by a deep, well defined and accu- rate bass-line. The RA-1062 includes a MM phono stage with inputs for Tuner, Tape 1 and 2, CD, and Aux. A 12 volt trigger, IR remote input, speakers A & B selec- tor, headphone output, balance control and con-tour switch round out the features of this superbly capable integrated amplifier. Extraordinary sound quality, remarkable flexibility, and unusual convenience highlight the RA-1070 Integrated Amplifier. Substantial power (100 watts RMS x 2) and a damping factor of 400 assure precise control of the most demanding loudspeakers. The high capa- city power supply features a Rotel-built oversi- zed toroidal transformer and British-made BHC slit foil capacitors for exceptionally fast response to the demanding peaks found in todays sources. The RA-1070 allows connection of up to eight sour- ce components including a high quality MM phono input, five additional line level inputs and two inde- pendent tape monitor circuits. It also features discrete On/Off codes, 12 volt triggers, an RS-232 interface, two preamplifier out- puts, speaker switching and a headphone jack along with system remote control.
