    ABOUT ROTE
The sound of excellence, without exception
The Rotel products you will see are all unique, including: DVD and CD players, pre-amplifiers, surround processors, post-amplifiers, radio amplifiers... etc. They originated from a family business with a 40-year history dedicated to designing and producing home theaters and high-fidelity audio components with high quality, reasonable prices, and outstanding performance. The so-called "production" refers to starting from the core parts, until the entire product is completed, everything is made by ourselves. It''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s in my own factory, under strict control.
The overall design strives for balance
The "Balanced Design Concept" rigorously integrates physics, electronics, and mechanical engineering into one. With our firm belief-the best does not need to be the most expensive-it leads its spirit. The beginning of "balanced design" started with an award-winning global team of engineers who conceived the basic circuit. The process includes a thorough evaluation of every part in the circuit, not just deciding which part is available, but finding out which part is the best choice. "Balanced design" also means that each of our review decisions is made by the most rigorous and sensitive instrument in the world, that is, the human hearing.
This is why our well-trained listening testers conduct the most critical review of each product prototype to assist us in making the most precise fine-tuning of the basic design until they can fully meet the strict standards required by ROTEL. "Balanced design" combines reliable science and skilled intuition at the same time, shortening the distance between you and lifelike audio and video. Any source, whether it is music or movie, can be on the scene, and you can listen to it without compromise. The voice that the artist really wants to present to you is nothing more, and of course there will be absolutely no flaws in it.

                                  Over the years, everyone''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s first reaction when talking about ROTEL is: a high-cost, value-for-money fever brand. That''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s right, because of its high cost performance, ROTEL has firmly established a foothold in the audio industry, where competition has already reached fierce competition, and its products have begun to move toward high-end products in order to seek broader development space.
    ROTEL''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s new generation of products first undergo a drastic change in appearance. The color of the panel is changed from black to silvery white with metallic texture, and large handles similar to professional equipment are equipped on the left and right sides. The overall style is much rougher. , Showing the pedigree of European and American brands. In terms of subtleties, the new generation of ROTEL products has a high degree of completion like Toyo products, coupled with a moderate price and excellent sound quality, so that it has won the favor of more enthusiasts.
    RA-1070 is a high-end integrated power amplifier in the current ROTEL product line. The layout on the silver-white aluminum metal panel is quite simple. In the center is a data display window and volume control knob. On the left side is the power switch, remote control receiving window, earphone jack, speaker control switch and CONTOUR（A kind of equal loudness control）Switch; on the right are two rows of small buttons, the upper row is used for signal input selection, and the lower row is used for recording output selection. When the power is turned on, there are usually two CD characters on the left and the right in the data display window, which makes people feel a little puzzled. But in actual operation, you will quickly understand that the left indicates the signal input selection, and the right indicates the recording output selection. Because the default selection of both is CD when the machine is turned on, two CD characters will appear.
    In ROTEL''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s past amplifier products, like the current Japanese amplifiers, most of them are equipped with treble, bass and left and right channel balance adjustment functions regardless of the grade. In a new generation of high-end products such as RA-1070, bold improvements were made, but instead of completely abandoning these relatively low-usage functions like European and American products, it evolved a function similar to equal loudness control such as CONTOUR. The CONTOUR control of RA-1070 has 5 gears, OFF is closed, and the frequency response is flat; L-1 boosts low frequency by 3dB at 100Hz, L-2 boosts 4dB at 100Hz; H is at 10kHz Increase the high frequency by 3dB; L+H is equivalent to enabling L-2 and H at the same time. For the current mainstream signal source CD player, this kind of slightly compensated adjustment ability is enough, and the operation is much simpler and more worry-free. Moreover, since there is no potentiometer with relatively poor performance stability, all adjustments are completed with a fixed-value resistance-capacitance element network, so the sound quality and performance stability can be improved.
    Observing the inside of the machine, the structure of the whole machine is similar to the style of Japanese models. A whole circuit board that is almost the same size as the machine bottom plate, covering all parts of the bottom plate except the transformer and the radiator. The two vertically installed circuit boards on the right are the signal input and output selection circuits; and the two vertical small circuit boards installed in the space enclosed by the radiator and the filter capacitor are the voltage amplification parts of the core of the power amplifier circuit. It is clear that the pair of tubes used for differential amplification are sealed in a transparent plastic sleeve filled with silicone grease. The purpose is to make the paired tubes that have been carefully paired work at exactly the same temperature at any time, maintain the perfect amplification waveform, and reduce distortion. Minimize. From the volume of the last-stage current amplifying output high-power tube, it can be known that the maximum dissipation power of a single one is not too large, so three pairs of parallel connections are used. The output power of RA-1070 is as high as 100W per channel, and the frequency response is also ultra-wide 4Hz~100kHz, which can fully meet the needs of SACD and DVD-AUDIO. However, ROTEL does not deliberately highlight this in its propaganda, and its awareness in this respect is quite similar to that of European and American manufacturers.
    On the back panel, RA-1070 provides 7 high-level inputs, 1 LP phono input and 2 recording outputs. There are also two sets of pre-amplified outputs, which can be used to connect to other post-amplifiers. There are two sets of speaker wiring terminals, in addition to the terminals used to connect the entire ROTEL system for overall control, and a computer connection terminal. RA-1070 is equipped with a very powerful remote control, which can control almost all ROTEL equipment. If you are a ROTEL persistent lover, and the whole set of audio equipment at home adopts ROTEL equipment, then this remote control can bring meaning. Unexpected convenience.
    Simple, natural, transparent and sharp, it is the best description of the sound quality of ROTEL RA-1070. Naturally, it also means that the accuracy of its tone reproduction is quite high. When you first listen to it, you will feel a little flat, but soon you will find that it has no sound staining and is completely Hi-Fi like Denon PMA-2000IVR. The style is different, and it is still very attractive in the mid-frequency part. It is a relatively slight warm tone dyeing, which makes the sound of strings, wood pipes and vocals a little thicker, but just such a little bit is enough to make the brain full of satisfaction through the human ear. RA-1070 performs particularly well when playing cello solo. The image is slightly introverted, so it can outline a very clear outline. The resonance of the piano body is noble, and it sounds really useful.
    For most of the time, this RA-1070 behaved politely, playing various types of music fairly well, and the balance of each frequency band was very good, and there was no section that was deliberately emphasized. The bottom of the sound is quite clean, and because of its excellent transparency, the details are very good, even not losing the Marantz PM-14SA. The sound field reproduction is quite stable, and the position and size ratio of the musical instruments and vocal images are just right.
    And when needed, RA-1070 can become very wild again. For example when playing“Bran Poetry”At the time, you can feel the amazing speed of RA-1070. It is not an exaggeration to describe the speed of an F1 car on the straight to 300 kilometers per hour from the stands. It is so fast! And with that kind of courageous spirit. Although the thickness of the low frequency is not particularly good, the strength and impact are equally breathtaking. The sharpness left a very deep impression on people. It is no exaggeration to say that after listening to RA-1070, change to any other power amplifier to play“Bran Poetry”, I felt unacceptable to all, until the next day I had a weaker impression of RA-1070 in my mind before I could treat the performance of other power amplifiers correctly.
    How to sum up this ROTEL RA-1070? I remembered what I saw some time ago“Medium beauties”The term is used to describe those women with medium appearance but rich connotations. They don’t know her if they don’t come into contact with them. Once they come in contact with them, they will be deeply attracted to her. ROTEL RA-1070 is one“Medium beauties”.
