Digital Room Correction For Speakers
Thanks for your reply in regard to digital room correction. I went with the DSpeaker X4 and am very happy with how it takes care of my slight bass hump around 150 to 200 hz. I do not use sub-woofers so could you please tell me what Amethyst brings to the table. The X4 was only $3750.00 on sale and greatly improves the sound when I care to use it. Thanks for your feed-back. Sam |
@lewinskih01 Would you mind giving examples of the following components you use for Acourate file creation? You need a mic and and mic pre, and analog to digital conversion I am about to take the plunge in with the Acourate software. I got the following book to lead me through it. I do not have a mic, mic pre and an ADC. https://www.amazon.com/dp/B01FURPS40/ref=pe_385040_118058080_TE_M1DP |
Certainly don't mind! They are also a consequence of how I got to this point, so let me provide more for perspective. Years ago I went from to PC as front end, after reading Mitch Barnett's articles on computeraudiophile about using Acourate for room correction. I was hesitant initially, so bought a Dayton EMM-6 calibrated much and a Tascam US-122mkII to connect the mic, convert from analog to digital and connect to the PC. I started with 2-channel digital room correction. I was using my audiophile -channel DAC for playback. I then wanted to explore multichannel stereo, following Mitch's articles. I purchased a Lynx Hilo as multichannel DAC/ADC, like Mitch had. I still have it. Uli Brueggemann, the man behind Acourate, recommends using the same device for DAC and ADC. So I use the Hilo. But the Hilo doesn't have a mic pre, so currently I use the Tascam set up so it just passes the analog signal it gets from the mic onto the Hilo analog in. Depends on the soundcard you use (Hilo in my case), you may or may not need a separate mic pre. Prism Titan, for example, includes mic pres. Ulis also recommends not using USB mics. as they are converting analog to digital internally. Is all this absolutely critical? Dunno! BTW, I have the book you linked to and is very good. Hope this helps! |
@lewinskih01 Thanks for the info. Today, with the experience you have gained, what mic, mic pre and ADC would you get for 2 channel only processing? As an FYI: In my room small room I will have 2 systems. https://systems.audiogon.com/systems/7605 My existing KEF LS50 will get a 3-D audio software processor. I was in contact with the following manufacturer and this sounds like something very interesting to try for about $5K. The hardware version of this setup is over $50K but I can try the same functionality with my computer based system. There is a microphone component that is part of this system along with something called a Babyface Pro http://babyface.rme-audio.de/ that is used to do the binaural microphone input into a computer. I wonder if the microphone and Babyface interface can work with Acourate? We also noted from the pics you noted that you must be computer savvy. In that case, you may wish to consider our BACCH4Mac sofwatre-based product which is much more affordable than the BACCH-SP. It is designed for computer audiophiles and the same functionality of the BACCH-SP (and more). https://forum.audiogon.com/discussions/theoretica-applied-physics-bacch-sp-adio-3d-sound-processor (a thread I created a few weeks ago) I will place the LS50’s on top of the large rectangular Yamaha NS 5000 speaker (using angled Isoacoustic stands) when playing the 3-D stuff via the LS50’s, otherwise the LS50 will be moved away to a bookshelf. The goal of the Acourate DSP will be to hopefully tame the large Yamaha into this small room. I also use ROON for my digital playback. If this all works as expected it will be a home run for what I wanted to achieve. |
What to buy is largely driven by budget. Mic: the Dayton EMM6 is good. Earthworks M30 and M50 are better and more expensive. I bought the EMM6 to try out DRC, then entertained the idea of upgrading and I consistently got the feedback the delta wasn't large enough. Pre: dunno. Uli used to sell one. Monacor MPA-102 was mentioned as a good option. Haven't looked much into it. ADC: here it gets tricky. You could use one unit for ADC and a separate one for playback (DAC), which is not what Uli recommends. Then regular DACs become options. Or you can follow Uli's guidance and use the same unit (same clock) for both conversions. I'm not familiar with the Babyface, but know several guys running Acourate use RME products. Merging has a new product (Anubis?) that had good comments. Prism Lyra, Lynx Hilo. It's not clear to me what the BACCH system does and how Acourate fits in the picture. Acourate enables turning your system into active, which in my experience makes a huge positive impact. In that light I would recommend a multichannel unit rather than 2 channel. I've taken the passive crossover out of my speakers, drive them directly, and there is no going back for me. Cheers! |
