SUMthang....coming soon.

keep us posted on progress and of course...how it works.

I marked the back plate for the TRS connector holes, and punched guide indentations.


Drilled guide holes.


Drilled the REAL holes!

Looking good, Skull.

Are you doing this project for analog summing or simply as a means of adding analog processing to individual tracks in a sum mix?

I love the fact that you have not indulged in any smoke and mirrors.

How about putting $1600 bucks worth of Jensen transformers in there next?

:-)

Keep up the good work.

best regards,
mike

Haha...Mike!

I did put this in a two space rack enclosure...there's plenty of room in here for you to come over and add all the goodies you want.

Plus you can help me with all this damn cable stripping I gotta do next!

Cant wait to hear it!

Wow this looks like a fascinating project!

I'll make a point of grabbing the .wav next time I am in town near hi -speed.

Cool Project!!!

Listened to both. I prefer the first file. It seems to have some realism, clarity and depth that is not in the second file. Overall there seems to be more transient information on this version.

The second file sounds more glued but in a slightly smeared, overall less depth and almost muddy type of sound. Sounds like more compression was added to this version.

Looking forward to the results.

Skull,
 Are you aware the FooBar2000 has a ABX addon that lets you listen and test yourself?

 I use that occasionally for stuff like this and probably will with your files as well.

best,
mike

Dude good job on your recording. Sounds cool. Good job!

As far as the 2 versions, I think I have a pretty keen ear, and seriously, not worth the oputboard gear. 

They both sound cool man. EQUALLY

Thanks, Lance.  You might be right.  But the next step in the process will be to throw in-line some hardware compression on some of these stems and run it all through the analog summing.  I've got 3 of the Furman RNC's and a DBX unit that could add some mojo.  We shall see this weekend, perhaps.
 
I'm just excited that I got the box right on the first try...no buzzes or hums of any sort.  I didn't even solder ONE cable together before I put on the barrel, which is my nemesis!   :o)

Mike...that Foobar ABX thing is pretty dang cool!  I'd never even heard of Foobar before.  Thanks for the heads up. 

I just finished the Foobar2000 ABX comparison test.

Whew... it was nerve wrecking to take it seriously... but I am sincerely interested in these results and wanted to do my part with regards to helping provide some accuracy.

Here is the log file generated when I finished the ABX process:

Total: 8/10 (5.5%)

mike's notes: POISON-BLACK-SUM-2-MASTER.wav seems to have richer bass tones while POISON-BLACK-SUM-1-MASTER.wav seemed to have flattened bass tones. I think that "2" might have had "more" bass as well...  the effect I heard was richer and more harmonious down in the low frequencies. I did not spend much time listening to the high frequencies.

::::::::::::::::::::::::::::::::::::::::

With a 5.5% probable error rate (I identified the tracks correctly 8 out of 10 times) I am feeling a bit more confident about my ears than I usually claim in discussions like this. I think the impressions I noted above are probably fairly accurate.

I personally prefer the rich tonality of POISON-BLACK-SUM-2-MASTER.wav

I can tell myself a bunch of reasons why it might be one mix or the other... maybe my favorite is a beautiful 64bit ITB mix? Maybe the summing box has *flat* (attenuated and less harmonically complex) bass because so many extra (16 vs. 2) D/A converters were involved? Maybe it's the exact opposite... maybe the extra converters provide extra headroom for the bass? Maybe the 64bit ITB mix can't give me that beautiful bass.

Gosh... now I am simply dying to know the answer.

I didn't dare read above to see if the answer was already posted... WHAT"S THE ANSWER???? :-)

:-)

Thanks a whole bunch Hook... I really enjoyed the opportunity to listen to a good song and the real thing .wav files.

best regards,
mike


edit to add: After reading some peoples impressions describing light and airy I think I will listen again tomorrow on another playback system and focus on the high end a bit.

Great thread Skull.

I could almost smell the solder when going through the build pages.
