Sony TA-E1000ESD AV preamplifier(From Hi-Fi Review) The Sony TA-E1000ESD control amplifier may well represent the beginning of the next step in the audio worlds transition from analog to digital signal processing. Essentially, this unit is a preamplifier with a built-in digital signal processor. And that makes it much more than a preamplifier. In functioning as a digital surround sound system, this unit electronically reproduces the early reflected sound as well as reverberations by using its digital signal processor. You can literally tailor the sound to match that of virtually any listening space, from large, cathedral-like acoustics down to small jazz-club environments. A built-in Dolby Pro-Logic surround decoder also makes use of the digital signal processing ICs to create the specific delay, response, and matrix decoding parameters established by Dolby Labs for Dolby Surround decoding.One of the features that impressed me most about this unit was its digital parametric equalizer. Three individual EQ bands are available. Each can be adjusted to have its center frequency at any point in the audio spectrum. Each band has a maximum boost and cut range of 12 dB (and the three bands can be ganged for up to ±36 dB of variation). Perhaps best of all, the slope or Q of each band can be adjusted from 0.7 (very broad) to 20 (very sharp or narrow).I found the highest Q setting particularly useful in eliminating resonances caused by structures or furnishings in some listening rooms. The combination of three bands offering such a wide range of adjustment proved more effective than even the most elaborate graphic equalizer. More important, by executing this equalization entirely in the digital domain, even adding the most extreme amount of boost in one or more bands did not increase measured or audible distortion, nor did it introduce extreme phase shifts such as might occur if an analog equalizer were to be used for the same purpose.The third function of this controller that is handled entirely in the digital domain is compression and expansion. By using the compressor feature in environments where background noise is high, you will hear sounds that might otherwise be masked by noise. There are no less than nine different compression settings available. Conversely, using any of the nine expansion settings can restore proper dynamic range to program sources that have been compressed, such as FM radio programs. Expansion also helps to eliminate undesirable noise between musical selections by pushing that residual noise downward below your threshold of audibility.The parametric equalizer, surround sound capability, and dynamics controller have been used by Sony to create and store 10 recommended sound-field programs, identified by such descriptive terms as Hall 1, Hall 2, Opera, Church, Jazz Club, Stadium, Live Concert, Theater, Disco, and Dolby Surround. Each of these environments has been programmed with specific settings of some or most of the adjustable parameters (including the size and wall reflectivity of the simulated room, your own seating position, center and rear channel levels, parametric equalization settings, effects level, early reflection time and level, reverberation time and density, surround-field spread, compression or expansion, and Dolby Surround delay times). Tables in the instruction manual show Sonys settings and which settings can be altered by the user for each of the 10 preset environments. Users can create 10 additional sound fields and store them in system memory for instant recall. For Dolby Surround mode, only the Dolby-specified delay time (20 mS) is preset, but the user can vary it from 15 to 30 mS. Center- and rear-channel levels can also be adjusted in this mode.Since the TA-E1000ESD is intended to serve as a preamplifier/control unit for just about any audio/video component system, it also incorporates a conventional analog phono preamplifier section. I was somewhat surprised and disappointed to find that the phono inputs accommodate only moving-magnet cartridges. If you own a moving-coil pickup, you will need to use a pre-preamplifier or a step-up transformer with your phono system. Aside from that fairly obvious omission, the TA-E1000ESD should be able to accommodate even the most elaborate of audio/video systems.Control LayoutAt first glance, the control panel of the TA-E1000ESD seems somewhat intimidating. After I had lived with the unit for a day or two, however, I realized that the layout was actually quite simple and logical and that a great deal of thought had gone into solving the problem of how to control such a vast number of adjustments without dozens, if not hundreds, of knobs and buttons. Sonys solution was to have two little rotary knobs control adjustments of just about every kind, depending on which parameters have been brought up on the visual display by means of other pushbuttons. For example, if you are in the Parametric EQ adjustment mode, one of these little rotary knobs adjusts the amount of boost or cut of the particular EQ band while the other alters the bands center frequency.Primary controls on the front panel include Power, display Dimmer, a row of input selector buttons, small buttons for selecting Parametric EQ or Dynamics (compression/expansion) or Surround, buttons for selecting the factory preset or user-set sound fields, a volume control, and a Muting button. To the right of the display window are the two small multi-function rotary knobs, and nearby are four small pushbuttons: Two for selecting main and subparameters that need adjusting, an EQ Band selector (for choosing which of the three EQ bands you want to adjust), and an EQ Slope button that sequentially alters the Q of the equalization band being adjusted. A headphone jack is situated at the left, beneath the power on/off switch.A hinged panel along the lower edge of the front panel swings down to disclose a row of secondary controls. Included are a Display mode button with three settings (display all information, display the input function only, or turn off the display completely), digital input level buttons, an analog input level knob, controls for adjusting Dolby Surround Input Level and Balance and selecting Pro-Logic mode, a Test Tone button that helps in adjusting balance among the speakers (front, rear, and center), buttons associated with memorizing your own sound-field programs, a Character button with which you can label inputs with your own names, an Effect Rec button (for adding digital effects to the analog record output signals), a Set button that selects one program source for recording while you listen to or watch another program, a Check button for confirming that selection, a Balance knob, and a set of audio and video input jacks for the S-Video input, including an S-Video input connector. Included with the TA-E1000ESD is a programmable remote control that, in addition to duplicating the functions of most of the front-panel controls of the unit, can learn the commands of other remotely controlled components.The rear panel of the TA-E1000ESD is equipped with enough input and output jacks to accommodate analog audio components such as a turntable system, a tuner, a CD player, and two tape decks. There are also enough inputs to accept the digital outputs of a CD player or DAT deck, either via optical digital inputs or via a single coaxial digital input.As for video inputs, there are four S-video inputs as well as an S-video output, plus regular audio/video inputs to accommodate three VCRs (plus a fourth, if it is a player only), a videodisc player, and a TV tuner. You will recall that there is a set of front-panel audio and video inputs as well, and these would more than likely be used for convenient, temporary connection of a camcorder when transcribing or editing videotapes. Two TV monitors can also be connected to the unit. For audio, there are outputs for connection to two stereo amplifiers for front left and front right speakers, a set of outputs to feed the rear-channel stereo amplifier, an output for a mono amplifier to drive a center speaker, and another for driving the amplifier that might feed a subwoofer if one is used. Four convenience a.c. receptacles (two switched, two unswitched) are also located on the TA-E1000ESDs rear panel, as is a terminal for connecting a turntable grounding wire.Use and Listening TestsTo demonstrate the capabilities of digital sound processing, I used a TA-E1000ESD and five CDs from my growing collection, each designed to illustrate a different digital signal processing feature. In several of these appearances, local audio dealers provided speakers and amplifiers for surround demonstrations. So I had quite extensive experience in setting up the TA-E1000ESD in a variety of rooms and systems.My first demonstration involved the parametric equalizer, and for this I used an album entitled Broadway Brass featuring the Empire Brass Quintet (Sine Qua Non 79002-2). Since the quintets instruments consist of a tuba, a trombone, a French horn, and two trumpets, I thought it would be interesting to highlight each of these instruments during a Sousa march. By revving up the boost and sweeping through the frequency spectrum to continuously vary the center frequency of that boost, I was able to bring each of these instruments up to solo position quite smoothly and remarkably. I had in the past tried this same demonstration with both graphic and parametric analog equalizers but had always felt that with such extreme boost settings there was an audible increase in distortion. Not so with the parametric EQ section of the TA-E1000ESD. Though each instrument moved forward as I swept the equalizer across the spectrum, sounds remained clean and crisp throughout the course of the experiment.I used a lovely organ recording from Towerhill Records (CD-900101, entitled The French Romantics, John Rose, organ) originally taped at the Cathedral of St. Joseph in Hartford, Conn. to demonstrate the advantages of the compression portion of the digitally processed dynamics circuitry. Here was a very light, fragile-sounding selection whose soft tones and subdued bass were easily buried in any kind of ambient noise environment. By adjusting for maximum compression, those soft, almost inaudible tones suddenly came to life, and sounds from the extreme bass pipes, almost inaudible because of human hearing characteristics when listening to low-level sounds, suddenly were clearly audible with all of their sonority.My next experiment involved moving my listeners (acoustically, not physically) about the halls in which the demonstrations took place. For this trick I used the original soundtrack recording of the film The Rose starring Bette Midler. By adjusting the front/back and left/right parameters on the TA-E1000ESD while we listened, I was able to transport those listeners seated nearthe center of the room to any other room location in which I wanted to place them. This effect is quite amazing and works much better in a room of normal home size than it did in the more spacious rooms in which I gave my talks. Even so, those seated centrally reported that they did feel that their position relative to Midler in our digitally created sound field had indeed shifted to the locations that I predicted.My final demonstration, which involved two discs, was designed to show how I could create a listening space of virtually any size and reverberation characteristic using the TA-E1000ESDs almost infinitely variable parameters. For the first part of this experiment I used an unusual Denon disc (PG-6006) consisting of works recorded by a symphony orchestra in a huge anechoic (reflection-free or dead) room. After playing a brief selection of such strange-sounding, lifeless music, I added a previously arrived-at set of parameters to move the sound into a well-designed concert hall. The results were astounding, to say the least. Now, the music sounded as it would have sounded had it been performed in an acoustically ideal space. Had my audience not agreed with the amount of reverberation, wall material, effects level, and audience positioning that I had assigned to this playback, it would have been a simple enough matter to adjust the parameters to their preferred settings.In my last playback experiment I used a Proprius CD entitled Cantate Domino (PRCD7762) recorded in Sweden. The instrument, again, was an organ, and the idea was to move it from the rather limited space in which it had been recorded into a cavernous cathedral. Admittedly, I exaggerated the size of the new hall a bit, giving it a reverberation time of some 3.6 S. Still, when that parameter was punched in for surround sound, the effect was very dramatic. At one point I simply put the CD player in the pause mode, and the reverberatory sound continued for several seconds, in accordance with the preset reverberation time; the reverberation issued from both front and rear speakers as it died away. Furthermore, that reverberant sound, created entirely by the digital circuitry, sounded fully as real as the primary sounds had sounded, with no audible distortion or other unwanted artifacts added.I could have carried on endless other experiments, but by this time, my audiences (and I) were convinced that the Sony TA-E1000ESD is a component that goes beyond anything yet devised as a consumer audio product. We all agreed that it represents, as I stated at the outset, the beginning of a totally new direction in the world of audio. Perhaps even more amazing than its digital audio capabilities is its suggested retail price. When I first saw the unit put through its paces, I guessed that its retail price would be precisely twice as high as it is. Other knowledgeable audio enthusiasts have guessed similarly. Sony is to be commended not only for coming up with an outstanding and innovative digital audio product but also for being able to deliver it at a price well below that of far less impressive and less versatile preamplifier control units.
