    Digital vs. analogue volume control for digital monitors

    @20hertz: Your setup intrigues me: In your super vinyl system you manage to avoid digitization all the way to the speakers. And then you’ve chosen digital monitors for this system. Can you tell me more about your thoughts behind this? I would have imagined that you would prefer older analog monitors from Genelec which would allow you to go analog also inside the monitors. I attempted to start a thread about this on the Genelec website, but it didn’t really catch on. Genelec Community Forum • View topic - How come nobody hates digital monitors? Maybe your experiences merits their own thread here on ComputerAudiophile?

    @nyatousga: How do I make sure that I do that?

    Digital vs. analogue volume control for digital monitors

    Good idea! ... Except, it would be difficult to get your system from Scandinavia to the island of Malta in the Mediterranean, where I live.

    Digital vs. analogue volume control for digital monitors

    Thank you, everybody! … Yes, theoretically, all of you are right! It doesn’t make sense to convert to analog, and then back again to digital. But the dealer who is of a different opinion is one of the biggest in Europe. I imagine they have listened to more active speakers than any of us, and probably also to each of them in more setups than any of us. I was looking for actual experience with comparing the digital to the semi-digital setup, not just logical thinking about how must be. (Then again, he might just be a temp, speaking nonsense.) I already subscribe to every one of DigiPete’s threads. :-) I wanted to hear from others with digital active studio monitor experience. In a few weeks time, when I get back to my apartment, the monitors will have arrived, and I’ll slowly start doing some experimentation on my own. I have a stressful spring and summer ahead of me, but at some point you’ll hear my two cents.
  5. I’m preparing for the arrival of my Genelec 8351A active digital studio monitors. They accept both a digital signal and an analogue signal. My dealer says I’ll get the best result by feeding them an analogue signal, because I can then adjust the volume in the analogue domain, which doesn’t reduce the bit depth of the signal, as any digital volume control will do. But I’d like a second opinion on this. Basically, I have these two options: A: Send digital signal directly to the monitor. The volume control will then be handled in the digital domain, either inside my computer or by the “Genelec Loudspeaker Manager” software inside the monitor. B: Convert the digital signal from my computer to analogue -> Control volume with an old-fashioned analogue pre-amp -> use analogue input on the monitor, after which the signal will be converted back to digital inside the monitor. Does anybody have experiences with the audio quality differences between these two approaches? Will I be able to hear the difference? If I had to guess, I would imagine that the all-digital approach might retain more attack, but be less smooth sounding, or perhaps a bit blurry due to the need for more dither. And that the analogue approach might introduce slight changes to the overall tone (which would be of no importance because they would be corrected by Genelec Loudspeaker Manager Digital Room Correction.) But I have no experience with this. I’m aware that it must be of greatest importance which kind of DAC and analogue volume control I use. At the moment I’m using a Benchmark DAC1 PRE, which is both my DAC and my volume control/pre-amp. The music I listen to is 16-bit standard CD quality upsampled to 24-bit in my computer. It must also be of great importance which analogue-to-digital converter the Genelec 83xx-series uses. I haven't been able to find any information about chipsets, shielding etc.; nor tests comparing the quality of the two inputs. Thank you for any help.

    USB (or Ethernet) to AES/EBU converter?

    Thanks again, everybody! Lots of input to digest! It seems that the product I’m looking for is called a Digital Monitor Controller. Here is a selection of monitor controllers with digital outputs Monitor Management | Sweetwater.com Most of them are for studios with a number of monitor sets, channels and inputs, but this little thing is more like what I had in mind TC Electronics BMC2 - Thomann UK Tons of positive user reviews on the web. It has a lot of dedicated fans out there in the home audio studio mixing world, but it’s close to ten years old and a newer model really ought to be on its way. Also, I’m a fan of compact, simple living, and my audio system was supposed to reflect this. No need for power amps, expensive cables, DACs etc. I wanted to go the active monitor way partly to keep the many “boxes” and wires out of my clutter free apartment. Now, it seems my “simple and compact digital monitor solution” is growing increasingly complex. I will need a USB to S/PDIF converter, then a digital monitor controller, then an S/PDIF to AES/EBU converter. Not to mention the Genelec Loudspeaker Manager box and, if I choose, one of the solutions mentioned above for a wireless connection. Yes, maybe I should use a Thunderbolt solution as DigiPete suggests. But that would require me to get an all new computer with Thunderbolt output. A huge effort to swap my entire digital work life and personal life to another computer exclusively because of my audio needs. And then, of course, there’s the option to move all my audio out of my work laptop to a dedicated media computer. But I travel a lot and like to bring my music with me. Thanks again, everybody. This is a great site with some great users. For the moment I will stick to feeding my monitors an analog input and keep everything compact, simple … and the way it is. But at some point, after I’ve catched my breath a few times, I’ll move on and conquer new digital continents.

    USB (or Ethernet) to AES/EBU converter?

    @Wakibaki: I don’t understand what you’re saying, either. :-) One thing seems to be clear from the comments above: My question is actually two separate questions. 1) How do I get a great USB -> AES/EBU converter, preferably with an all-digital preamp – that is volume control, source selector and at least one analogue input with an ADC? 2) How do I get a digital signal wirelessly from my laptop to this digital preamp? If this is at all possible without any audio degradation. I had hoped that there’d be one all-in-one solution, but that seems to be an unobtainable dream.

    USB (or Ethernet) to AES/EBU converter?

    Wow, DigiPete, I did not know that it was THAT easy to convert from S/PDIF output to AES/EBU input. That opens up the field a lot. Here are a few links, elaborating on your information. How to Convert Between S/PDIF and AES Digital Audio Format Converters | B&H Photo Video I’m aware that the volume on Genelec’s latest monitors can be controlled through the GLM controller, but I’m reaching a shortage of USB outputs on my laptop and would prefer to not have GLM controller connected all the time.

    USB (or Ethernet) to AES/EBU converter?

    Thank you very much. This is indeed a website with many friendly people! :-) If AES/EBU is a standard in professional music recording there really ought to be a number of cross-over products from the professional world. Digital mixing consoles with 1-4 channels and/or preamplifiers with USB and analogue inputs, a physical volume control and an AES/EBU output for active studio monitors. Much like the Benchmark DAC1 PRE had XLR output and was a preamp from music studios. Anybody know any? I’ve found other threads on this forum discussing the same issue. These have a few years on them, but they are interesting none the less. Here are links: Building a 8260A system to support both 16/44 and 24/192 playback http://www.computeraudiophile.com/f6-dac-digital-analog-conversion/best-universal-serial-bus-industry-standard-cables-connectors-and-communications-protocols-between-computers-and-electronic-devices-audio-engineering-society-aes-world-wide-professional-society-devoted-audio-technology-european-broadcasting-union-ebu-professional-society-devoted-audio-technology-it-originated-europe-broadcasting-radio-and-tv-converter-16177/ http://www.computeraudiophile.com/f10-music-servers/server-dual-audio-engineering-society-aes-world-wide-professional-society-devoted-audio-technology-european-broadcasting-union-ebu-professional-society-devoted-audio-technology-it-originated-europe-broadcasting-radio-and-tv-output-and-volume-control-14067/

    USB (or Ethernet) to AES/EBU converter?

    Just came across this thread, which is packed with information (without mentioning AES/EBU in the header.) Building a 8260A system to support both 16/44 and 24/192 playback Still no mentioning of a product, though, that adds a volume control, and which takes input from Wifi. I suppose some micro version of a professional studio mixer with USB and analogue inputs will be the way to go. But what do they sound like? How do they work, seen from an audiophile perspective?

    Basic updated intro to Auralic Aries, please?

    Thank you so very much, bplexico and miguelito! A huge help, and a huge effort from you to help me! My music files are stored on my laptop. Yes, the Genelecs include DACs and ADCs. These loudspeakers go digital all the way to within the speaker. It seems like I need to look at some other options. I’m not looking for a music player, I’m just looking for a way to convert a signal from USB or (preferably) wifi into AES/EBU. On the CASH list there are converters to S/PDIF, but not to AES/EBU. I really need some recommendations, but this is the subject for a different thread. So I’ve started one. Here it is. http://www.computeraudiophile.com/f8-general-forum/universal-serial-bus-industry-standard-cables-connectors-and-communications-protocols-between-computers-and-electronic-devices-or-ethernet-audio-engineering-society-aes-world-wide-professional-society-devoted-audio-technology-european-broadcasting-union-ebu-professional-society-devoted-audio-technology-it-originated-europe-broadcasting-radio-and-tv-converter-23813/

    USB (or Ethernet) to AES/EBU converter?

    The C.A.S.H. list has recommended converters for USB to S/PDIF converters, and for Ethernet to S/PDIF converters. Computer Audiophile - Computer Audiophile Suggested Hardware List But my soon-to-own professional studio monitors, Genelec 8351A, only accept analogue input and then the professional digital format AES/EBU. Then what? I’d prefer an Ethernet to AES/EBU converter, but a USB to AES/EBU converter will also be interesting. I’d also prefer a unit with a volume control – and perhaps a source selector and an analogue input. Does anybody have suggestions or tips?

    Basic updated intro to Auralic Aries, please?

    Audio_ELF, I have read the review, which alerted me to this product in the first place. There are 132 comments to the review. Many of them listing problems, solutions, corrections and the evolution of software updates. Computer Audiophile - Auralic Aries Review There are 1947 comments to this discussion of the hardware http://www.computeraudiophile.com/f22-networking-networked-audio-and-streaming/auralic-aries-hardware-impressions-and-information-21261/ There are 820 comments to this discussion of the software http://www.computeraudiophile.com/f22-networking-networked-audio-and-streaming/auralic-lightning-ds-app-software-impressions-and-information-21262/ And then experiences with this product are also mentioned numerous other places on this site. I just wondered if someone was capable of giving an overview of whether this product would work as I imagined, so I wouldn’t have to read 3000+ comments.
  14. I can't believe the amount of pages on this site on the Auralic Aries and its software and continual updates. I do like to read about computer audio, but this seems insurmountable. My questions are basic: Will I be able to play all audio from my laptop wirelessly through this streamer? That is, can I play system sounds, J.River Media Center, internet videos and iTunes without audio lagging behind video? Will it be as simple as now when a USB connection lets my Benchmark DAC1 PRE play anything without any fuzz? Will I need major changes and/or additional investments to make the Auralic Aries work? The details of my system: I have a Windows 7 laptop connected to a Benchmark DAC1 PRE via USB. The reason I intend to change this reliable and simple setup is that I plan to go digital all the way to my loudspeakers. Soon, my new Genelec 8351A digital studio monitors will arrive. They accept analogue input, but analogue signals are converted to digital inside the speaker in order to make use of digital filtering and an elaborate digital room correction system. It seems “anti-audiophile” to let my signal be converted back and forth two times between analogue and digital. Genelec 8351As only accept digital input in the form of AES/EBU, which my Benchmark DAC can’t provide. (I don’t play esoteric hi-def files, I do like to have a volume control outside my PC so as not to accidentally blast my system – and ear drums – if there is a computer mishap. I’d love to get rid of that USB connection and go wireless, I don’t have an iPad, and my phone is Android.) Auralic Aries seems to be the way to go in my situation. But am I missing something in the 100s of pages on this product? Thank you, in advance
  15. People told me that the T500 is a dead silent and pretty powerful laptop. I didn’t believe them because I’m so much more fuzzy about background noise than most others. But they where right! That is, with a solid state drive in the T500 they are. Also, pressing a single button it is possible to take out the DVD drive and replace it with a bay for a secondary hard drive. My setup in my new T500 is • one 80GB Intel SSD with Win7-Ult.64 plus all programs and smaller files • one 640GB Western Digital 5400 rpm HDD with my music This way, my everyday work is silent, but when I start playing music the windy sound of the HDD will set in – which is unnoticeable at medium to loud volumes of audio playback. (I now rip from an external DVD drive). However, lately, my T500 hasn’t been 100% silent. At times, a drrrrrrr-sound is there for 10 seconds, then gone for a minute, then back for 10 seconds, again and again. The sound isn’t as ‘loud’ as the ‘sssssssh’ of the HDD. (My girl friend ridicules me when I mention it, but I imagine my fellow audiophiles would find it annoying, too.) The solution seems to be a program called TPFanControl http://www.staff.uni-marburg.de/~schmitzr/donate.html. It is amateur-made and free. TPFanControl.exe lists the temperatures of all sensors in a ThinkPad laptop, measures the fan speed, and allows you to set rules for when the fan should start, and for how many RPMs it should spin at in a series of temperature intervals. I’ve chosen to install it in a way that it doesn’t change the BIOS or the registry; it’s simply in the start menu and I can turn it on when my native fan control starts its drrrr-silent-drrrr-silent routine. I’ve only used it for one day, but I’m overjoyed. No problems, at all. And finally to my question: This free little wonder is set up for the ThinkPad T61, by default: CPU temperature, bus temperature, power supply temperature – everything is set up with the values that work best with the T61. (Also, the program is set to neglect all data from a so-called ‘Sensor no. 5’.) It’s pretty easy to change these values, but nowhere on the web have I found information on which settings would work best for a ThinkPad T500. So far, I’ve enabled ‘sensor no. 5’ without any problems. My laptop is 100% silent again, and still cool to the touch, but I have no way of knowing e.g. if the bus temperature is actually the CPU temperature and vice versa in a T500. Would anybody here have any TPFanControl experiences to share?
