Prism Lyra 1 USB Audio Interface Review Posted
After bugging Prism for more than a year to get one of their interfaces
to review, they finally sent me a Lyra 1. It's a really high end USB audio interface, too expensive for the penniless desktop studio singer-songwriter, but putting it through its paces was a good opportunity for me to see how the other 1 percent lives. The usual Mike Rivers Way Too Detailed Review is now available for your enjoyment and education in the Product Reviews section of my web page. Even if you're not hot to buy one, I try to work some generally useful facts into my reviews, so check it out. You might learn something about similar devices. My Reviews: http://mikeriversaudio.wordpress.com/product-reviews/ If you just can't wait, you can go directly to the Lyra review he http://mikeriversaudio.files.wordpre..._review_mr.pdf -- For a good time, visit http://mikeriversaudio.wordpress.com |

Or more likely code for "TL;DR". Is it possible to put an executive summary up front, then the firehose later? Just a thought. I can understand that, but I wouldn't agree with it. But you can't tell what somebody's tolerance for detail will be. Hey, your review of the Focusrite stuff helped me buy something, so it gets no better than that.

SFAIK, that means every reviewer has to be a registered author for it. The only money might be advertising or donations. I dunno what that means W.R.T. potentially negative reviews and such. -- Les Cargill |

Prism Lyra 1 USB Audio Interface Review Posted
I have been usng an orpheus for about 2 years now, and they're nearly interchangeable. So I agree with all you said. The sound is stunning.
I love the way you write reviews. I can actually get a sense of what the product can and cannot do and what kind of sound quality to expect. I made mention to Ty in an email awhile back the same thing- I wish more magazines employed you guys to write their reviews. Ty's mic reviews are so useful. I'm sick of reading reviews in magazines and they basically reprint the ad copy and then say "it sounds good!" Mic reviews are the worst- i recently read a review in a magazine of the newest coles ribbon mic. I would have liked them to comment on the front back symmetry and the deep ness of the nulls, but instead all they did was discuss how it's good for guitar amps and drum rooms. What a joke. That review told me nothing. Most microphone reviews these days are interchangeable.... Scott writes very good mic reviews that I see published but I don't recall seeing one for awhile? N |

That makes me feel good. Thanks. The only money might be advertising or donations. I dunno what that means W.R.T. potentially negative reviews and such. While we point out downsides and personal gripes, most of us aren't inclined to give what would be considered a negative review. I've never had anything in here that I thought was so bad that I just plain wouldn't recommend it, but if I did, I'd be inclined to send it back without reviewing it and telling the manufacturer about the problems. But these days there really isn't much junk and the differences tend to be in how features are implemented and how useful they are. A great performing unit that's too hard to operate deserves to be reviewed as such. A promising device that just doesn't do anything useful should just go back without a review. I feel a certain degree of responsibility to both the readers and the manufacturers when I write a review. I don't want to slander anyone, but on the other hand, I don't do a wide variety of recording work, so it's easy for me to miss a compressor that sucks on drums but works great on vocals. If I'm handing out information in a forum, I'm more comfortable with the feeling that it's just another opinion - take it or leave it. -- For a good time, visit http://mikeriversaudio.wordpress.com |

I was going to include one, but, y'know, one SMD board looks like any other SMD board unless you get down to individual components. I suppose I could have taken a close-up of the converter chips just to validate my text, but what's the point? Really the only thing interesting inside the case was the shield around the power supply section. At least it wasn't difficult to get open. I would have liked to see what was inside the Focusrite Forte, but I couldn't figure out how to open it up and be sure I could put it back together. They don't like it when you send them back a box of loose parts. -- For a good time, visit http://mikeriversaudio.wordpress.com |

At least a few of us here on RAP would find a photo of the PCB interesting and informative. You wrote that the unit was not easy to repair because it's all SMD, but there are different kinds of SMD parts, some larger than others, and are more open to repair, depending on individual skills. A pic of the board would show the component package technology used. Plus, some electronic designers like to gawk at circuit board designs to learn from them. |

It's gone now, so I can't take a photo for you, but for future reference, what would you like to see? Can you point me to a photo on the web or on a file host that shows what you'd find valuable? And also point out what you're seeing that's useful. I'll try to help next time around if you can convince me that a photo would be more useful than just to prove that I was able to open the case. Incidentally, I tried to get a good picture of the different color states of the meters and it just wouldn't work, even with a fully adjustable digital camera in the hands of a decent technical photographer friend. If the top red section was on, half the meter photographed red, and that's not what it really looks like. My friend speculated that a film camera might work better for this application, but we didn't bother. You wrote that the unit was not easy to repair because it's all SMD, but there are different kinds of SMD parts, some larger than others, and are more open to repair, depending on individual skills. Trust me on this one. When I said that it wasn't easy to repair, I meant it's not something that the average user would attempt, or if he tried, would probably not be successful at it. Maybe one out of a few hundred users will have the tools and skill to repair it, that is, assuming you could get a schematic and board layout drawings from the manufacturer. But in the real world, if anything on the circuit board goes, perhaps with the exception of a power supply component, it's not going to be repairable by anyone but the factory. I've replaced a couple of SMD 2-terminal parts if there's some working room, but this was so cramped that I didn't have tools small enough to work with. But then, I'm still in the analog and discrete world when it comes to service. -- For a good time, visit http://mikeriversaudio.wordpress.com |

True, but they don't pay their writers (or at least they weren't paying for articles when I asked a few years back). They do have a lot of advertisers, that's for sure, and it's not junker class gear that they're advertising, so somebody must be buying it. Some of their reviews are pretty good. I wish I was more interested in the stuff that they review, though. -- For a good time, visit http://mikeriversaudio.wordpress.com |

It's gone now, so I can't take a photo for you, but for future reference, what would you like to see? In terms of the circuit and performance, if you can get the printing on the main chips, such as the codec, it can help identify the exact part. From there, it's possible to look up the corresponding datasheet and learn a lot about the quality of the product. It's nice to see the brands of electrolytic caps in the power supply section, too. There are many brands of very cheap and unreliable Chinese caps on the market, and a few that are well known to be top quality. It's a very common point of failure, so it matters. (And it's also easy to repair if those caps are through-hole.) You don't need to get that in the photo; if the caps are Nichicon, United Chemi-con or Panasonic, just tell people. In general for SMD chips, there are footprints that are so tiny that virtually no human can solder them, but there are also older, larger footprints (such TSSOP) that are just half of the 0.1" through-hole packages from the 1970s that we all love. It requires learning a few new tricks, but they are actually very easy to work with. I repaired my M- Audio DMP3 with a TSSOP chip, and it was the first time I ever worked with an SMD chip! Incidentally, I tried to get a good picture of the different color states of the meters and it just wouldn't work, even with a fully adjustable digital camera in the hands of a decent technical photographer friend. If the top red section was on, half the meter photographed red, and that's not what it really looks like. My friend speculated that a film camera might work better for this application, but we didn't bother. I have much better than decent technical skills in photograpy. From what I'm seeing in the photos in the article, the first thing you need to to is use brighter lighting so the light level on the case more closely matches the brightness of the LED display. The LEDs are simply overexposed, which will mess up the colors. After that, you may need to adjust the color of your lighting to match the color balance of the LEDs to the other things in the image. To get your camera's color balance set right, use a standard photographic gray card that has a flat spectral response and about 18% reflectance. (E.g., Kodak R-27) Then use the camera's custom setting for color balance (or "white balance") with that as the reference. I think that much should do it for you, but I can't be sure. If not, there are further refinements possible. Maybe one out of a few hundred users will have the tools and skill to repair it, that is, assuming you could get a schematic and board layout drawings from the manufacturer. It's not always necessary to have an exact schematic or understand the circuit completely. Often, designs are based on reference designs they got from the manufacturer. I repaired my DMP3 just from looking at the circuit board and discerning how the circuit generally worked, looking at the INA163 datasheet, probing some pins to see that something was wrong, and making a logical guess. It was easy. That doesn't happen all the time, but sometimes it can be like that, or even simpler. But in the real world, if anything on the circuit board goes, perhaps with the exception of a power supply component, it's not going to be repairable by anyone but the factory. It really depends, and that is why it's nice to see a pic of the circuit board. If there are no custom proprietary chips, and you can identify all of the chips, and look them up on Mouser or Digi-Key and order in quantity of one, that's a big plus! I've replaced a couple of SMD 2-terminal parts if there's some working room, but this was so cramped that I didn't have tools small enough to work with. But then, I'm still in the analog and discrete world when it comes to service. Look up "soldering smd" on YouTube. There are some really good lessons. (Try Dave Jones's EEVblog.com site - Episodes - #180, #183, #186, #434.) I got over my fear of SMD that way, and now I think, "If they can do it, I can." |

From there, it's possible to look up the corresponding datasheet and learn a lot about the quality of the product. I could read it with difficulty, and I put the info about the codecs in the review because I knew that some people were going to want to compare what's used in this unit with what's used in some other unit, then start a discussion on Gearslutz along the lines of "The $2,000 Lyra uses the same converters as the $200 M-Audio (OK, I don't know if that's true but you get the point) so why is it so much more expensive? It's nice to see the brands of electrolytic caps in the power supply section, too. In order to do that on this unit I would have had to disassemble it even further since the power supply, except for some vent slots, was pretty thoroughly enclosed. I wouldn't expect a company like Prism would use cheap components. if the caps are Nichicon, United Chemi-con or Panasonic, just tell people. I've heard of those brands and if I notice them, I might mention them. There was very little on the main board that's identifiable. I don't know how to tell which of those little rectangular chips are resistors and which are capacitors, much less the brand names. In general for SMD chips, there are footprints that are so tiny that virtually no human can solder them, but there are also older, larger footprints (such TSSOP) that are just half of the 0.1" through-hole packages from the 1970s that we all love. What part of "it's practically unrepairable" don't you understand? Do I have to prove this to you? You're reading my review. Take my word for it. If it was easy to repair, I would have mentioned that. From what I'm seeing in the photos in the article, the first thing you need to to is use brighter lighting so the light level on the case more closely matches the brightness of the LED display. The LEDs are simply overexposed, which will mess up the colors. Tell that to Prism. I'd have to look at the review again, but I think that all of the pictures were either screen shots or came from Prism's "high resolution" press photo library. The reason why I tried to photograph the meters myself was that I wasn't satisfied with the stock Prism photos. You DID read the review, didn't you? It's not always necessary to have an exact schematic or understand the circuit completely. Often, designs are based on reference designs they got from the manufacturer. I repaired my DMP3 just from looking at the circuit board and discerning how the circuit generally worked, looking at the INA163 datasheet, probing some pins to see that something was wrong, and making a logical guess. It was easy. OK, you can try fixing your Lyra when you get one and it breaks. Most people who get into a failed device will look for a blown fuse or a charred resistor. I can trace analog signals, but when it comes to logic beyond simple gates, there's really nothing I can do to figure out what's wrong. If your problem is with an op amp, yeah, that's not difficult assuming you can remove the bad one and replace it without buggering up the board. If there are no custom proprietary chips, and you can identify all of the chips, and look them up on Mouser or Digi-Key and order in quantity of one, that's a big plus! This ain't no $200 mic preamp. I'm not really writing reviews for repair technicians who fix things when they break, I'm writing for people who are going to use them and hope that they don't break. To be honest, I'd take a crack at a mic preamp that quit working, even if it was mostly SMD construction, but I know my limits. I have a small Mackie mixer, a 402 VLZ3 I think, that has a dead headphone amplifier. The way it's packaged, it needs to be completely disassembled to even see the component side of the board, and the chips are really packed closely together. I wouldn't take a chance on screwing something else up trying to repair it. And for sure I'm not going to get my soldering iron close to a $2,000 interface with a lot of digital stuff on it. I might tackle the power supply if that was clearly the point of failure (which isn't too difficult to determine) and it was Sunday and I needed it for a session that night. But I've got good sense and I'd send it back to the company for repair. Look up "soldering smd" on YouTube. There are some really good lessons. Yeah, like I'm going to trust myself to work on an expensive piece like this with what I learned from YouTube? Nope. I have some ChipQuik and have used that to remove a part and replace it when I could get in to work on it, but I only chanced working on something I cared about after removing and replacing a bunch of surface mount parts on a PC graphics board that I picked out of someone's Free Stuff pile at a hamfest, just to have something to practice on. Look, Jay, I write these reviews because it gives an opportunity to play with stuff that I wouldn't buy (either it's too expensive or I don't need it) and I share them with those who are interested for all the fame and glory that it gets me. It doesn't get me any money. If you've like me to further into the design and construction, I'll be happy to give you a quote. You have some valid questions, but you're very different from the user for whom this gear was designed. An Ampex AG-440 was designed for a different kind of user and was built to be serviced (and in fact there are full schematics in the manual) because every recording studio and broadcast station had a tech on board or on call. This is not the case with today's studio gear, even units such as the Lyra, that would be comfortably at home in any top tier studio today. They just don't make studio techs any more like they did in the Ampex days - because they don't make gear that way any more. -- For a good time, visit http://mikeriversaudio.wordpress.com |

I have been recording my vidcast audio thru my Mbox2 Pro with a Heil PR40 but the vocals sound a bit coarse to me and the Mbox2 Pro is getting a bit long in the tooth. (old) The SOS review of the Twin was good but did not go into enough detail on the sound of the convertors. The converters in my Apollo Quad sound good without being too analytical.

I don't add new stuff very often, but you'll get an e-mail when I do. When I get up to 900 visitors a month, I can get a press pass to CES (they used to give me one until they made that rule). There, for me the only difference between going as press and going as a regular flunky is that press gets a free sandwich for lunch if you get there in time. I've been thinking about writing an article on how I test things (get the numbers) and how you can make those same tests on your own gear with not much more than what you already have as part of your regular studio gear. -- For a good time, visit http://mikeriversaudio.wordpress.com |
