"Excellent" parts have been substituted by "good parts", and in the majority of cases "average parts" in anything below $3,000. Not sure when the Gen 2 version came out. I left my Lip sync at "Auto" and don't have a problem. The total noise on each side of the balanced circuit is the same as in a single-ended signal path. A new firmware almost every 2 weeks to fix the unfixable. Never used the internal dacs, but Im using the XMC1 as a preamp/Reference Audio. Skip to content. Maybe your TV/projector is doing heavy processing causing a delay hance sync problems. But while the io is a cruder listen, it still seizes the strings abrasive texture and captures the foreboding emotion, while tracking their dynamic movement too. Can you let us know if you are using Infineon Memtool ? The design restrictions on the op-amp are similar to the LSI AVR chip, but we need a buffer after the CMOS switch. The XMC-2 is surprisingly light for a high-end processor which my back appreciated as I carried it around: Ironically, the remote is made out of metal and weighs a ton as remotes go. The +/-7.5V supply is for all analog electronics except for the op-amps connected to the XLR and RCA outputs. All these crappy reviews have me very disappointed in Emotiva. It can also be utilized as a very good stand alone dac if you ever decide to incorporate hi-rez computer audio into your system. Everything is tested by our dedicated team of in-house reviewers in our custom-built test rooms in London, Reading and Bath. Taking our final look at the XMC1 board, we see three more relays for a total of twelve. This chip is balanced and has current outputs. Thanks! This solution is adopted in the Bryston SP3. These TI ASRCs are two channel parts, so four are used on the DAE-7D. Feb 25, 2020 #1 This is a review and detailed measurements of the Emotiva RMC-1 AV Surround Sound Processor (for home theater). Which would sound better for audio performance analog input from a 105 or digital input from the OPPO 103? I love the sound of the unit; best of all, it has reference quality analog audio (balanced XLR/RCA) path for reference audiophile two channels listening. Our expert team reviews products in dedicated test rooms, to help you make the best choice for your budget. Specs & Downloads Overview The RMC-1 is a state-of-the-art surround sound processor - designed from the ground up to serve as the nerve center of a modern home theater or surround sound music system. So does this appeal to the lifestyle crowd? What Hi-Fi? A smaller chance exists that it is a TI 4190 which has slightly reduced performance. Oct 2, 2019 #1 This is a review and detailed measurements of the Emotiva XMC-1 Generation 2 Home Theater Processor. Yorkshire AV - friendly HiFi and Home Cinema retailer based in the heart of Yorkshire. Excellent parts have been substituted by good parts, and in the majority of cases average parts in anything below $3,000. Little Ego. Of interest is an examination of the complete XMC-1 final design (below), which showed an unused volume control and some unused switch segments. For this reason, care needs to be taken in selecting the power amp to interface to the XMC-1. Non-linear capacitance of a MOS device also adds distortion at higher frequencies. Also Audyssey XT32 only does dual subs if it also includes SubEQ HT. Since correction to 96kHz or 192kHz takes at least 2x or 4x as much processing power as to 48kHz, manufacturers would need to install 1-2 more DSP units to be able to do this. I finally pulled the trigger on the XMC-1 preamp. The issue would be how it Audyssey decimates higher PCM sampling rate files of 88, 96 or 192khz down to 48Khz. Lots of questions, but I'm interested to find out more about the XMC-1 and Dirac. CD-100. It is possible to purchase individual high voltage, low resistance switches, but they must be turned on individually with a separate digital chip converting the serial control stream from the CPU into the separate control wires. As an aside, the XLR inputs are directly switched to the ADC which has balanced inputs (most quality audio ADCs have balanced inputs). Design tradeoffs for a stereo preamp are very similar to the ones made for the XMC-1, so even if you have no interest in home theater, this article should supply useful information. . Summation of the 5.1 DSD signal cannot be done in the digital domain since the resultant signal is no longer a 1 bit stream. Weight 2.9kg. The RCA outputs in the Emotiva XMC-1 come off pin 2 of the XLR. The switch has only two positions: the DAC output or the 7.1 multi-channel RCA inputs. Audyssey does it at 48khz, ARC at 96khz. The chip operates with +- 7.5VDC power rails which are a limitation imposed by the semiconductor process technology JRC uses for this device. Stereo Zone 1, Zone 2, and Record need a converted source for DSD in stereo. How would you compare these room correction systems?? They dont use fancy brands cables with exotics features: why is that? emotiva.com, I got an XMC-1 and I do agree with the sound quality being "Decision 1". If so how precise are the measurements?? Rather than gripe about it and get banned from the Emo forums, I've decided to move on. Above is a block diagram which shows how the balanced current output is converted to a single-ended voltage. There are two from the PCM5102 DACs (HDMI and SPDIF), the four stereo analog inputs, tuner, the XLR input converted to single-ended, DSD mixed, and 7.1 RCA mixed. Note too that Rega has done well to keep quality and character consistent through the headphone output. The most interesting switch position is the fourth when the XLR analog input is passed directly to the balanced switches. In a standard Pre/Pro or AVR, the added electronics of a single-ended-to-balanced converter is needed before the ADC. This will be discussed below. The XMC-1 as analog in. You can see a 3-layer sandwich of boards from those I/O positions. Some designers would want to increase the complexity of the analog power supply regulators, but it is not clear to me this is required. This is not the place to discuss Ethernet controllers, and audio USB design needs its own article. https://www.pls-mc.com/products/flash-programming-ude-memtool-flash-programmer/. As we add more blocks in each single-ended path, the difference between the in phase and anti-phase paths increase and the ability to cancel distortion declines. Dan Laufman, president of Emotiva, discusses the companys design approach for the preamp: The main left and right channels are fully balanced, input to output. #1 This is a review and detailed measurements of the Emotiva XMC-2 Audio/Video Processor (AVP). No balanced-to-single-ended converter is provided by Emotiva. Sources. When you purchase through links on our site, we may earn an affiliate commission. These photos have enough resolution to blow up and see part numbers on key chips. Inputs RCA x2, MM phono. The instruction manual suggests using stereo zone 1, but this is not the optimal solution. is part of Future plc, an international media group and leading digital publisher. It can do processing up to 96kHz if the necessary DSPs are present, but in every implementation I've used it only goes up to 24kHz because of the lack of DSP processing power for it. This 3rd layer board has the XLR I/Os mounted at the back of the board. Bath . Monoculars. Since the left and right channels require two channels, half the CS3318 is used. That doesnt necessarily mean that such a pre/pro or AVR wont compromise the input source; the signal must still pass through the switching circuitry. . The main channel left and right outputs from the NJW 1298 are converted to balanced signals internally in the NJW1298 and enter the balanced volume control through the NJW1112 switch which was discussed above. This processor sounds very similar to the $2000 Benchmark DAC2 (which destroyed the $6000 PS Audio Directstream in SQ). Instead, Emotiva has chosen to put the money into the parts that affect the measured performance of the unit. The PCM1502 DACs are associated with the stereo Zone 1, stereo Zone 2, and the record output jacks on the rear of the unit. The DAC-stages balanced outputs are connected directly to volume controls. A microcontroller and flash memory are also part of the system control and are likely on the front panel board for which I do not have a photo. It is common to use AVR LSI chips for analog stereo Zone functions and tape outputs. The TI PCM5102 will not accept DSD inputs, so the stereo signal is created by the summation of the 5.1 signal coming from the output of the main PCM1796 DACs. The DSP also processes the PCM inputs from HDMI, USB and SPDIF sources. Trail Cameras. Using the HDMI in the XMC-1, would use the DAC in the XMC-1. The third layer on the bottom is the PC board containing the data converters and analog components. The worst case distortion is 17 bits equivalent. 0.02 dB at 20 Hz Future Publishing Limited Quay House, The Ambury, XMC-1 is a processor, so it will give your room EQ, like Dirac, REW support, many HDMI connections, etc. This show how confident they are about their build quality --but I am glad you got your money back. Above is my PC board identification from a photo of the cover removed from the XMC-1. AVRBalancedCMOSDACsDSPEmotivaPC BoardsXMC-1. The balanced main channel can pass direct to the volume control or the ADC. XMC-2. The second switch position is to connect the left and right RCA plugs of the 7.1 input to the volume control. This prevents the photo from becoming too complex. 54 Results Brand: Emotiva Brand Number of Channels Audio Inputs Audio Outputs Condition Price Buying Format All Filters Emotiva BasX TA-100 Stereo Preamp/DAC/Tuner/phono/ With Integrated Amplifier $400.00 $61.11 shipping or Best Offer 10 watching SPONSORED EMOTIVA XPA-100 MONO BLOCK AMPLIFIER BRAND NEW SEALED, MAY SALE ! The reason the balanced-to-single-ended converters are retained is to take advantage of the reduced noise and distortion that occurs when the signal is converted to single-ended. 0.17 dB at 20 kHz Note the open layout of components on the high quality PC board material. The power amplifier designer may also see this circuit block as a place to cut costs. Entry Level Or Reference Projectors: Is There A Difference? All two-channel single-ended inputs (3 back and 1 front) and the tuner signal are connected to a New Japanese Radio (JRC) NJW1298 AVR LSI. The performance of the PCM 1796 relative to other DACs is found in the chart below, along with products that use it. The 7.1 RCA inputs are also summed in the analog domain to stereo by a pair of op-amps. The other TI PCM5102 is for Zone 2. This is shown in the block diagram above. . Where does the XMC-1 stand? Similar quality DACs are seen in most AVRs or Pre/Pros for external Zones. The answer is the main channels may have room correction applied. The alternative use is to listen to phono with room correction. This is good enough not to degrade the performance of a good phono stage like the Emotiva XPS-1 in moving magnet mode; indeed it exceeds the requirements of the best measuring phono stages. This could damage the parts on the lower power supply. In the simple diagram above, I show only a two switch pair. Differential reference monoblock power amplifier (28 pages) Amplifier Emotiva XPS-1 Installation And Configuration Manual. At the beginning of this piece I said the XMC-1 is a paradigm of a Pro/Pro implementation. The block diagram above shows the signal flow from the DAC to XLR outputs for the center, surrounds and subwoofer channels. To reduce distortion, Emotiva again uses a balanced topology. Zone 2 can be configured to play audio from a different source (either digital or analog). Rohm and Renasis also show no +/-15V audio switching chips on their websites now. Rega certainly isnt trying to hide the fact that most of its efforts have gone into the performance. I assume the Emotiva power amps are designed with the output of the companys preamps in mind, but I do not have schematics of the products with a single-ended or bridged main amp topology to see what the differences are. They prevent transients that occur on power up and power down from appearing at the outputs of the main channels, stereo Zone 1 out, stereo Zone 2 out, and record out. Tip / Sign in The balanced signal is passed directly to the power amplifier. While this DACs performance is a significant reduction over the TI PCM1796 used for the main channels, it should be good enough for systems connected to the external zones. Riflescopes. The TI headphone driver IC (TI TPA6130) is on the front panel, and this part has balanced inputs, so extra op-amps only need to be added. This regulated output keeps the front panel alive, waiting for front panel or remote command for the system to power up. Both techniques minimize distortion. I believe enough has been said regarding delivery delays. The switch matrix has 72 NMOS-PMOS transistor pairs for maximum flexibility. The operation of this chip is discussed in the article linked below. The long ribbon from the analog board to the front panel is for the headphone jack and front panel stereo input. No? It is part of a new generation of high-end processors sporting 16+ channels of audio. The trade is that the high frequency switching clock must be kept off the analog supply rail. Virtual Home Cinema: Getting Beyond the Hype, B&W Launches Signature Versions of its Iconic 800 Series Speakers, Shopping for a New TV? With closed back headphones the smallest amount of hum or noise will be audible. With two CS3318 chips, we have 16 total sections, and 11 are used for the multi-channel main outputs. However, because you purchased a UMC-200, you are eligible for a 25% discount, making your cost $1495. The XLR output is produced using an inverter to produce the negative (pin 3) output. www.hometheaterhifi.com/technical/technical-reviews/audio-video-receiver-build-quality-part-ii-design-of-high-performance-avrs-and-pre-pros/. Its not far off half its price or half its performance and so, quite reasonably, it has half its name. NAD has jettisoned the 7.1 inputs on its highest priced products which have no AVR LSI. It does what it should to justify its extra spend over the io, keeping it relevant in Regas line-up between the io and Elex-R. I got the impression that you need to set each speaker level to 75db and enter each speaker distance before running Dirac. Above we see the full block diagram from DAC to XLR. According to Audyssey, there is nothing about Audyssey that causes it to be limited to a 48kHz sample rate. These extra relays perform the same function as the nine we identified above. It's easy. This is especially true for the new stereo products with integrated DACs and USB audio inputs. I've got a 5.1 system used for movies and music. I must note, however, that New Japan Radio has removed the +/-15V audio switch offerings with serial control pins from the website. . Skip to content. High precision low noise phono preamp (8 pages) Amplifier Emotiva XPA GEN3 User Manual. Indeed this was the prime use of AVR LSIs outside budget AVRs before the cost reductions on the main channel began. The third position is for the stereo inputs (three on the rear panel and one on the front). Try defeating all video processing on your display. If I were you, I would get a processor; and latter get the following Oppo model to the 105, with native 4K, once money allows. Open switches for analog direct path are not shown. In addition, Emotiva said they will keep updating the XMC-1 unit to keep up with the times. On the DAE-7D board are two TI dual 300MHz DA710 DSP chips designed for audio application (TI brands these Aureus). Play Drakes Money In The Grave ft. Rick Ross, and the ios nature comes to the fore, its natural sense of momentum driving the dominant bassline forward. I'm an Emotiva fan and have lots of their stuff. The problem is identical for relays, but with the additional issue that each relay must have a high current driver to energize the electromagnet which controls the relay. A traditional Pre/Pro has a single-ended signal path. The XLR input is converted to single-ended. After much listening and comparison I went with the Marantz. http://mds.com/wp-content/uploads/Datasheets/Audio/DAE77_rev1d.pdf. Some data sheets actually disclose performance improvement of a component in balance but not the NJW1112. The Emotiva approach sounds nice at first, but it has just passed the job of performing the balanced-to-single-ended conversion to the power amp. The top pair is turned off blocking IN 1. Above this price point, higher priced op-amps or discrete op-amps, in the case of the Bryston SP3, replace the NE5532. The Oppo 105 is an excellent player, but you're looking to update, right? Only a small fraction of the switches are used in any given application. Post by KeithL onMar 2, 2021 at 7:01am. If Emotiva wanted to spend part of the bill of materials for parts to add features like multiple standards of wireless connectivity or Ethernet streaming audio functions, the added chips would go on these boards. Although it could be independent, Emotiva sends the signal on Zone 1 to tape out. Anyone compared the Emotiva XMC-1 vs stand alone DACs? Should I Connect My Apple TV to the TV or Receiver? Our coveted five-star rating and Awards are recognised all over the world as the ultimate seal of approval, so you can buy with absolute confidence. It cannot be added in firmware. to post questions, reply, level up, and achieve exciting badges. The part options are discussed throughout Parts I-III of my AVR build quality series. We use science to evoke the true emotion behind every note. At least one product I have evaluated does nothing, assuming the op-amp current limit will keep the switch IC from being damaged. Italian Audio Junket Part 2: A Visit to Gold Note. The power amp then converts this balanced signal back to single-ended. This again allows us to identify the boards, and note the clean and open layout of the unit. XMC-2. To the foot? Since the PCM1796 is used for all channels, and this DAC is a fully balanced current mode device, the circuitry around it that we discussed above is retained. Are you comparing to an Integra 80.3 or an Anthem D2v? Three switching regulators are identified. The HDMI digital stereo signals are converted to analog by the TI PCM5102 DAC single-ended voltage mode. Considering you get 7.1 channels, tons of processing, and is around $2200, this is incredible value compared to buying a stand alone DAC. Do you have any post processing video devices? Holder of fourteen patents, David's industrial experience includes ten years at Bell Laboratories where he rose to Technical Manager. The XMC-1 has Dirac which helps with movies, games, music room EQ. Audio Frequency response at preamp outputs of Dolby Digital decoder: Left (aqua): 0.02 dB @ 20 Hz, 0.13 dB @ 20 kHz. The compact, half-width aluminium chassis feels well built the same goes for the satisfyingly simple remote control and its low-key design should suit some hi-fi traditionalists. The MC1 features six HDMI 2.0b video inputs and includes support for enhanced ARC (eARC). I hope Emotiva keeps its promise on making the XMC-1 "completely modular and up-gradable to meet future standards.". In the section on data converters, I noted the PCM 1796 DAC. The CS3318 volume control is powered by +/-7.5VDC, a limit imposed by the CMOS process technology used for this part. Below are the main parameters of Soviet mokika: power plant - -57 / 58 with a capacity of 2.2 horsepower and a volume of 49.8 cubic centimeters; the maximum speed is 50 kilometers per hour; muffler - motorcycle type; weight - 75 kilograms; advanced steering wheel; years of production - from 1978 to . The entire process takes just a few . 0.00 dB at 20 Hz As a result, the PCM1502s distortion performance declines significantly. I show this signal flow below: In a traditional preamp design (stereo or multi-channel), the balanced XLR input is converted to single-ended and then follows through the single-ended path of the component. For the S/PDIF and AES/EBU signals, an independent digital switcher is used, which routes the selected signal to the Zone 2 PCM5102. The XMC-1 will be there for some time to come. Home Audio Systems, Speakers & Accessories and more. The 105 soon will be replaced with a native 4K model. Not shown on the schematic is a relay at each output which is open on power up and power down to prevent transient signals that occur before the power supplies reach full voltage on power up or as the power supply collapses on power down. The tradeoffs between using switched or linear regulation in the analog power supply is an area of significant debate between design teams. Before we remove the case, let us look at the back of the unit. Unlike other users of the DAE-7D, Emotiva makes its own copy of the board, stuffs it with parts, solders and tests it. The Emotiva XMC-1 has a fully balanced signal path from the DAC to the XLR outputs. Only the CMOS switch, in the closed position, connected to DAC, is shown in the block diagram. The audio DSP section is the DAE-7D, sold by Momentum Data System and found on much more expensive Pre/Pros sourced in the US and Canada. The DAE-7D drives the DACs on the AXMC-1. Regular price from $5.00 Sale price from $5.00 Unit price / per . Sample rates up to 192kHz or even beyond would be supported. It is not clear why New Japan Radio does not offer switching chips with this process. You need to be a member in order to leave a comment. All those I/O jacks are attached to PC boards. January 5, 2019. All rights reserved. Emotiva *finally* released their XMC-1 preprocessor. This is one of many reasons most audiophiles don't use EQ and only listen to stereo --but this is all preference. BasX MC-700.

By the by, as an Oppo 105 owner I don't think its DAC implementation is anything special, however it may look on paper. The HDMI board also covers the back of the DAE-7D DSP board. This information allowed me to take a deep dive into the assembly of a Pre/Pro and the results are discussed in this article. What Hi-Fi?, founded in 1976, is the world's leading independent guide to buying and owning hi-fi and home entertainment products. Emotiva DC-1 Professional Desktop DAC. Each switch at the input of the volume control has four positions. It is likely that unlisted +/-15V switching chips are available on an exclusive basis to companies running very high volume production, but such chips would not be available to Emotiva. I meant it has a sample rate of 48kHz so it only works out to 24kHz. Sound quality wise is in line with top level delta sigma DAC. Anyway, what will you pair the oppo/processor with? The reason is because 48khz sampling rate it could reconstruct frequencies up to 22 kHz. Bryston used 33 pairs of DPDT (Double Pole, Double Throw) relays in its very expensive Pre/Pro. The worst case SNR is 18-bit equivalent. I know New Japan Radio (JRC) has a +/-18V CMOS process which is used on its high end volume control with no op-amps (MUSES72320). Most XT32 components have it, but it's not a requirement for XT32. A quaint showroom with lots of character : Tel 01757 826111. 0.00 dB at 20 kHz BasX MUSB Slim USB Cable Accessory. The simple reality is that, when it comes to modern DACs, there is more and less difference than you might imagine. He is a member of the Audio Engineering Society High-resolution Audio Technical Committee. Mercifully missing from a stereo unit would be the video output board and the need for a TV. The io sports two line-level inputs (two fewer than the Brio) and an MM phono input, so you can hook up a turntable as well as a couple of components such as a CD player and streamer. The electronic volume for Zone 2 is on the NJW1298. Bowers & Wilkins 606 S2 Anniversary Edition, 3 rookie mistakes to avoid when buying speaker cables, 3 key qualities that make a good reference hi-fi system, Save nearly 50% on two five-star wireless speakers at Amazon, The best home entertainment buying advice, Issues delivered straight to your door or device. As it leaves the XMC-1, the fully balanced signal contains the correlated even-order distortion. Center (green): 0.02 dB @ 20 Hz, 0.12 dB @ 20 kHz. The lack of analog video switching or HDMI scaling in the XMC-1 also helps make the rest of the PC boards more visible. My real qustion was intended to elicit a comparison of the XMC-1 Dac versus a well known DAC as is in the OPPO 105. These are the limited set of commands supported by the Infineon memtool. Between the two DSPs is an Asynchronous Sample Rate Converter (ASRC). I question the usefulness of these inputs for a product with a high quality internal DAC. More expensive products with Dirac have additional DSPs which run at higher sampling rates. This is the same signal path that the surrounds and subwoofers have, as we will see in the next section. What frequency does Dirac do its corrections at?? What will most win fans over to the Rega io, though, is its class-leading performance. David has been a professional reviewer of audio equipment for more than two decades, serving as Technical Editor for The Audio Critic and Sensible Sound. I wish reviewers compared the analog input versus digital/HDMI inputs on high end procesors. Another set of selector switches with additional active electronics precede the connection to the NJW1112.

It lists for $1995. The 105 soon will be replaced with a native 4K model. The implementation of Audyssey on most audio equipment only allows 48khz sampling rate @ 24bit. The Zone 1 volume tracks the main volume and cannot be adjusted independently. So someone could do this, but their unit would cost more than other models with similar features, and it's a feature more people wouldn't understand when they're trying to sell it. With no digital inputs? XPS-1. With the layering of the boards, only the HDMI board is completely visible.
