does the the bozak really sound that much better than the urei?

i know from reading various sites and articles that the bozak is supposed to sound a lot better, due to the discreat circuitry. for those that have both, is there one unit that u prefer??

also i've noticed that there are various modifications that have been done to bozaks, from the effects loop, to the additional aux inputs and booth control. do any of these modifications degrade the sound quality at all??

i've noticed the bozak with the booth control in a pic on mick's site and one was up for auction on ebay this week. the lack of booth control was one reason for going for the urei over the bozak, for me a booth control is vital.

i'd be interested in hearing opinions on this

thanks

I have made a few of the mods mentioned to my bozak. I converted it from a 10dls to a 10dlb. My mixer used to have 3 phono inputs 2 aux and 1 mic. After the mods I have phono 1, 2, aux 1a & b wich is set up for phono, aux 2a & b, aux 3a & b, and a mic. Giving a total of 4 phono, 4 aux imputs and a mic. I also added a booth out. None of the mods changed the sound in any way. I was told that the booth out can reduce the main out buy about 4db but i have not noticed any changes. The lack of ouput can be compensated by changing a couple of resistors but I did not bother to change them yet becuase I didn't knotice a differance and the main out is already 24dbm wich is alot and probally why I didn't knowtice any loss since I never get my main output anywhere near max. All of those mods are pretty safe to make becuase all you are doing when you make them is converting the mixer to one of the last models that was produced, so the only real risk is if you make a mistake yourself. Another good mod to do to the bozak which I did was to add output transformers on the main outs. I did this becasue the stock xlr outs are not balanced. For that make sure to use good transformers I used Jenson's. With that mod I also noticed no change in sound. The man who helped me with the mods is a guy named Mario and he sells completly redone bozaks, and is a good contact for parts. You can reach him at Djmariog@aol.com. Hoped that hepled.

Although the Bozak doesnt have as many inputs or a booth out this as stated in the previous post can be altered. However, the Bozak definitly has an even warmer sound than the Urei. It also has a stronger sounding more organic bottom end. and the top end is in fact sweeter than the urei. The urei is good, but the Bozak just gives the music something the Urei doesnt have. The midrange of the Bozak also has a meatier sound to it. This is due to the all discrete circuitry. In other words there are no chips in the Bozak. Chips are known to be a little edgy sounding and if you ever really listen to the Urei you can hear a little bit of hashiness particularly in the top end. Another thing to point out is that the Bozak was designed in the late 60,s when we were right in the middle of the transition from tubes to solid state and the Bozak was voiced to emulate the tube sound that was and is still favored by many. I use both Urei and Bozak and they are both good but my favorite is the Bozak!

hello all

first of all i would like to thank allen for mentioning my name for the mods done to his mixer, but the real thanks goes to my dear friend buzzy beck who had sent me the schematic original from bozak, that were all stamped top secret notes (buzzy will get a kick out of this) again THANK YOU BUZZY BECK. if you need any mods or parts for both bozak and urei contact me

I am probably in the minority here when I say I think the Urei sounds better than the Bozak.

I have had a Bozak, Urei and an A&H 92 rotary in my setup. I had all three together for about a month while I did my testing. With all the EQ's flattened out on the mixers, the A&H 92 sounded like AM radio compared to the other two. While the A&H was perfectly quiet at the loudest volume, it had no personality. The A&H 92 rotaries had most of their curve in the last half of their turning radius. You hear nothing till about 4 or 5. All the blinking lights were cute at first, but annoying after about a week. Kaka. I sold the A&H 92 immediately. I realized am no fan of the "british eq".

My Urei got sent away to get modded and I have my friends Bozak running for the last 3 months on it's own. The sound of the Urei is what I prefer. I can't wait to get it back and drop kick this Bozak out of the setup (big BIG shout out to Vinman for letting me listen to it). My Urei is circa '82

I would say it depends on what music you listen to. Deep house, and anything pre-80's sounds wonderful on the Bozak. Better than the Urei. But all modern styles of dance music (IDM, Detroit 313 techno, breaks, etc..) sound better on the Urei. The Urei has this tight punchy bass that makes the music sound fantastic. The Bozak has a deeper bottom and a more organic sound.

Your mileage may vary. You can't go wrong with either one. Ultimately, I would pick based on what kind of music you will be playing on it mostly.

House & Disco only? Bozak
Everything Else? Urei

pacifica, california I agree with you! I love my old Bozak for disco and house, when music had more midrange, but my old urei is punchier sounding, although not as deep as the Bozak. But, with much of todays overly bottom heavy music, it seems to translate better through the Urei.

What mods did you have done to your urei? And why?

:D

I find it interesting that the screened Bozak logo has worn off this mixer, but all the other lettering is in tact. Mine was the same way except worse. It looked like someone had intentionally sanded or scraped off the logo. In fact, I wondered if it originally even had a screened logo, or if it used to have a badge glued on. There used to be a picture on Mick's Music page (maybe its still there) showing a top view of a silver unit, and that one looked like it had a badge that stuck out.

Anyway, I searched ebay for about 18 months, and finally came across some plastic Bozak badges that came off some old speakers. I put the nicest one on my mixer, and still have a spare that looks pretty good. If anybody on this board wins this mixer and wants my extra badge, let me know. You can have it for free.

Here's a picture. The gold adds the pimp factor... :D

Mario is the person to get in touch with if you are going to do anything with a Bozak.

OK, I am old but I think as many know, that a BOZAK is the best mixer ever made. It is becoming harder and harder to find a good one. As my freinds have said on here, you need to be patient but I could not wait. After getting ripped off on a ebay purchase of a BOZAK, I purchased the new UREI LE version. For home mixing, I love it. Especially since it does not have, as someone on here said before 200,000 turns on the pots.

The old music in the late 70s and early 80s sounded amazing on a BOZAK, interesting that some would say today it is less important than before becasue of the current, TRASH, I mean music

I have ALWAYS been a BOZAK person. NEVER ever liked the UREI.

Your correct, I purchased my first UREI mixer from DJDeals.com

Must say, they were FANTASTIC. The first uint came and one Channel did not work, they FEDX a new unit the NEXT day and it is perfect.

That is what I mean about the old BOZAK Units, sure they are better souding but one must consider WARRANTY, support etc.

Too me, an avid fan of BOZAK, the new UREI LE is HOT, sounds good and is NEW.

Sorry but that has to be worth someting. Would really love to see it go HEAD to HEAD in a BLIND comparison.

Can you beleve I of course WON that dispute and got all of my money back but the son of a bitch put a negative comment in my ebay file ?

they would never know if you swapped out cards, unless the mixer is sealed with factory tape or something, you would just pull out the stock card and put the duo in -- pretty simple really -- that switch they have is nice, you could even put it on channels 3/4/5 and switch the toggle to preamp from line -- totally reversable

BIG Dipper!!
big one right?
i haven't have UREI's dipper before but i heard they are good sound!
it is mono unit and usually it helps to dip the frequency which you don't appriciate.
i hope it's good for you, but i recomend graphic type of eq.

and i don't think you are crazy.
if it's possible to fit using bozak's eq to urei mixer is very exciting.
they use ab mod pot so will be good sounding.
i use bozak mixer with full 10 eq(full CW) sometime.
pretty mad right? :D

ah, so 'cut only' EQ...
there are a pair of little dipper available at a shop in denver, I saw a month ago... also pretty expensive

for EQ I use White 4400, on Scott's advice. I really like them... best EQ I have ever used...

ALmost as if my big old boxes are covered in film before EQ, after EQ everything is sparkling in my ears...

mad is good in my book...

I have reverse switch in my 1200mKIIs , lots think that is mad too...

I like the different pots in for the balance but cannot give a direct comparison. I removed my balance pots because they were scratchy. Than a few months later I put in the AB mods for balance. I don't have much for comparison since so much time elapsed. As far as the tone control mod. The pots were never changed. I did the mod for the defeating them listed in the urei manual, but than switched it back to stock.

The reason some are now jumping onto the Urei bandwagon is that its solid state sound might be considered better for music that is less musical, less soulful and more machine like-basically much of the techno, etc. is just drums and a few synth washes. Going with a Urei's an admission the material's musically very limited.

Instead of switching opinions with the wind and using a Urei like everyone else, if you know how to tweak what you have a Bozak will win out, sound better every time. Just takes a little individuality, an understanding that you don't have to sound just like everyone else. In return, you'll have something more unique.

As long as your mind is open, that is..

Some people have both Bozak and Urei, and find one mixer more suited for some music, and the other for another genre of music.

Just know how to work it. Actually, the Bozak is suited for any type of music. However, IMHO, I love older disco and music thru 80,s into the early 90,s using the Bozak, BUT, with todays music, I like the urei because it doesnt accentuate the bottom as much as the Bozak, considering todays music to be overly bottom heavy, and midrange lacking!

But, I love the way the highs sound through the Bozak, and sometimes the bit of midrange sharpness from the urei seems to fit the bill better for me.

It really is up to the user to define what he or she likes.

i love the sound of "fresh frako" bozak.
but many of them are better to replace capacitors and transistors
to make their sound to the best.
but even without refreshment it still sound best for someone who need the sound.

i know some sound system need to tweak but i don't know why you need to tweak the sound of bozak :confused:
