I have a death wish! My buddies at work have one too they just don’t know it yet LOL. I will report back assuming I’m able to type after trying this stuff :D
Ok these guys look like they mean business too!
I like it! I’ve had some pretty strong coffee in my day… hmmm… I’m not sure the stuff we drank when I was in the Marines could still be called coffee hah!
I will be trying this coffee very soon. I hope my heart doesn’t explode.
ok I must try this…

Ok I was pretty excited to get this to work, get it hooked up, and see how it would (hopefully) improve my sound.
Well… not so much LOL. So After all my research today, I have to call the box a success, because it absolutely works, BUT it did not improve the sound as I would have liked.
Evidently there are issues when you combine two signals like the Left and Right from a Stereo signal, I can’t fully explain it, but the short version is, when you combine two like signals they cancel each other out to a certain extent. This box is combining the signals as I asked it to do, physics is cancelling out quite a lot of the high frequencies so it sounds like I’m listening to my music through a sock. :/
Have I learned something? yup! Did I get to build something and have fun in the process? yup! Ok so mission accomplished, more or less lol.
So, after making all these new discoveries I did more research, there must be a way around these shenanigans! I did more searching on the Rane website and actually found that not only did the original author of the Why not Wye article still work there, but I found his email address!
I emailed Dennis Bohn, pleading for mercy and would he spare a moment of time to further explain to me why this seemingly simple solution to my audio woes had actually made it worse?! Much to my surprise, Dennis got right back to me! WOW! Here is his response.
Yes, you are correct about the potential loss of fidelity due to monoing a stereo signal.
The problem is one of phase cancellations (and—flipside—amplification). This occurs when the same frequencies are present in the two different channels but are out-of-phase, i.e., one is positive and the other is negative, so they cancel; and if they are in-phase then they add and it gets louder in that band. And this happens even when the signals aren’t exactly 180 degrees out of phase; just at a lesser amount.
A true hi-fi mono signal can only be created by recording a sound source with one microphone, or multiple microphones but summed at the recording board. Cancellations and amplifications can still happen but it is the recording engineers job to minimize such anomalies.
It is ironic that this is most noticeable with the best sound sources since they have a better dynamic range with extended high frequency delivery.
Sadly modern recordings are so compressed and processed that this phase cancellation phenomena is seldom noticed. Too many modern recordings sound mono to begin with.
This says that you may be happier with just using one channel to listen to, rather than going to all the trouble of monoing. Strange but true; you might like it better.
However, the best solution is to go back to stereo and get some sort of a stereo playback system. Even a smaller, cheaper one may sound better than a bigger mono unit.
Hope this helps.
Thanks for the inquiry,
Mystery solved! So, one thought… I have a box that will produce a suitable output for a sub woofer! In the event that I rebuild my work system I will no doubt add a sub. So this box may yet find a permanent home in my work system!
Also, another article I came across showed that the high frequency losses experienced and values for those losses so I applied an EQ curve to compensate and the audio is greatly improved but I can tell there is some obvious loss of detail. I will likely begin looking for a new amp to build and suitable speakers for my cubical environment! Woohoo! new project LOL! I love building stuff. Even when it doesn’t work out, I learned something I wouldn’t have if I hadn’t tried to change and improve my system and now I know why it didn’t work.
Enjoy the music my friends!
One of my tech friends posted this… and all I have to say is A-FREAKING-MEN!!!!
This is outstanding, but stop and think for a moment, this applies to like every person out there who performs in a support roll of any kind.
if youre having a bad day just watch this
I will always reblog this. Sometimes it’s good to have a reminder of the awesome things that can only happen in a city like NYC (or, you know, any big city that has artists hanging about all over the place)
Haha perfect way to start my Monday morning …awesome

Stereo to Mono box.
I have a single channel amp at my desk at work. I used to have a single channel SET amp and it’s entirely possible it failed because I killed it but I will never know. I recently noticed the output I was hearing from my speaker at work was sounding funny. It never entered my mind that I couldn’t use a Stereo to Mono cable to sum the signals from my stereo output from my pc to a single channel. Well I was wrong, which might explain why it was sounding funny. After doing some research online I found the Why Not Wye article which does a much better job of explaining why this is not a good idea than I ever could.
I also found a premade box at one of the vendors who I have purchased transformers from in the past. However, the cost of the device was reasonable, but shipping was retarded and for the cost of 1 + shipping… I could build a half dozen of these myself. So… a trip over to Mouser and $10 later including shipping… 2 project boxes and parts enough to make a dozen of these, I just happened to be out of these resistors so I got a handful of each.
Parts were very inexpensive, the RCA’s are cheap, the project boxes were $3.00 each and the resistors were .11 for the 2 Dale 470ohm and .16 Dale 20kohm. So all told we’re talking less than $6.00 to make this little gem.
So, if you run a single mono channel anywhere, and this includes most sub woofers, and don’t have this type of device, toss one together it was a snap. The single RCA connector was my inner Audiophile crying out for help lmao. I love the new Black Neutrik REAN connectors. The small 6” connector is also shielded, cool right? :)

these are amazing I love them. Kids today would probably have no appreciation for this stuff… sad really. I love the go-cart, it made me smile. You just don’t see this kind of workmanship anymore. Beautiful.

WOW… I just got done washing todays haul. I’ll just be for cutting my feet off now ><
Ok not really but I almost wish someone would, they hurt from standing there doing what I do to make them all sparkly. Lets not forget… some of todays finds were seriously nasty looking… I normally look at everything before walking out and there were like 5 of them that would not have normally passed the “wow that’s not worth the effort” filter, but my cleaning solution does a HELL OF A JOB! Baring a physically damaged LP, I am way impressed with my results today.
The big surprise today? John Mayhall on the London label. Mental note… read the jacket before buying something I have no idea what is LOL. This is the paragraph at the top of the back of the jacket;
The recordings contained herein are not state-of-the-art stereophonic hi-fidelity. The performances were captured live on simple equipment, some at 3-3/4 IPS. NONE OF THE SIDES HAVE EVER BEEN AVAILABLE TO THE PUBLIC BEFORE; their current historical value transcends recording limitations.
Initially I was like what the hell is wrong with this thing which is what prompted me to read the jacket. Ahhhh!! Ok… some historic value, I can dig it. Actually pretty cool in that regard but difficult to listen to because the audio quality is really pretty lousy, but cool none the less. So it probably won’t get played often but I can see myself pulling it out now and then.
I jokingly asked the owner if he would sell me stuff by weight ;) he laughed.
Here is the List of all the stuff I brought home today.
John Mayall - Primal Solos
Boston - Boston
Bryan Adams - Reckless
Eddie Money - Eddie Money
Billy Squire - Emotions in Motion
Billy Squire - Don’t Say No
Eurythmics - Touch
Bad Company - Desolation Angels
Bonnie Raitt - Green Light
Bonnie Raitt - Home Plate
John Cougar Mellencamp - uh-huh
John Cougar Mellencamp - Scarecrow
Wang Chung - Points on the Curve
Van Halen - 1984
Bryan Ferry - These Foolish Things
Bryan Ferry - Another Time, Another Place
The Romantics - In Heat
The Fixx - React
The Fixx - Phantoms
The Fixx - Reach the Beach
Steely Dan - Gaucho
Steely Dan - The Royal Scam
Fine Young Cannibals - Fine Young Cannibals
whew! and thus far… I haven’t been disappointed with a single LP. I have played through a handful of them and started with the nastiest looking ones so I could sort them out but miraculously… everything has sounded awesome. The Van Halen will be a true test, that one looks like it’s pretty scratched up so I’m expecting it to be noisy. I think one of the Steely Dan’s has some heavy scratches too which is a shame but still, cost for these was 2.99 - 3.99 with the John Mayall the big spender at $7.99.

Small Business Saturday, well as much as I like the idea of Black Friday + Record Store day… I do NOT do well with large crowds pushing and shoving so I went to one of the shops I like and brought home 23 LPs including this John Mayall, no idea what it sounds like but it looked like fun so there ya go
Audio post - Played 8 times
Albert Collins, Robert Cray, & Johnny Copeland, Showdown! I ran across mention of this LP via an audition and review of another preamp I was interested in. I found a solid copy on eBay and picked it up. This is a very cool album. I washed it this afternoon, I think it sounds very good!
