Dangerous 2-bus
(D2B)

http://www.dangerousmusic.com/2-bus.htm

I have bought one of these to help me mix DAW sessions and use all my analog outboard. It sums 16 mono or 8 stereo pairs to 2 with a trim pot on the master out….

So far I have patched into it via my 16 interface outputs like so

Pair 1 = Kick (1) & Snare (2) (mono’ed)
Pair 2 = Rest of kit
Pair 3 = Bass (5) Lead Vocal (6) (mono’ed)

Pair 4 = GTR’s
Pair 5 = reverbs & FX
Pair 6 = anything individual I want to put analog processing on
Pair 7 =
Pair 8 = (I will be trying separate compressed drum mix

Sonically I have found the kick snare & bass all have benefited greatly from this box. In fact everything sounds better, I feel I am able to get more punch & ‘ruder’ mixes when using the D2B in conjunction with outboard (just go from the interface out to the outboard you want to use and then back into the D2B) and it has been nice not to have to be concerned with DAW plugin induced delays!

From a vibe standpoint it is great, I am back on familiar turf, tweaking my analog outboard toys at mixdown.

The levels in to this summing gizmo are basically set (there is a useful +6 dB boost button), so one aspect of using the D2B, is that all level moves in the DAW are pre the unit and will effect outboard like compression but that known, can be worked around.

So I am happy, it represents a significant sonic leg up for me and my DAW based studio.

I have been operating at 44.1k for the last 3 years because I was mixing ‘in the DAW’ to make 44.1 CD’s . I aI'm now to try tracking at 48k to squeeze a few more frequencies into the range. I plan to capture the analog output of the D2B with a separate 44.1 24-bit converter (Crane Song Hedd) feeding via AES a Masterlink. Later, I can record these mixes back to my DAW set up for a 24 bit 44.1k "mastering’ session where final eq, maximizing & dither can be added (or take the AIFF files to a mastering house)

So it is IMHO, YET ANOTHER "must have" for the DAW studio along with: a controller with faders, good converters, a Masterlink and a FATSO..

"just go

Hi Jules, this has been my setup for years. I have certain things hardwired to my outboard gear and others left open. I have a couple of questions about your setup though:
1)Lets say you are using all of your 16 outs, what do you do when you want to use more outboard gear?(multi compressors and Eq's, outboard effect processors that don't have digital ins and outs). Will you have to buy another Digi 888 or whatever? Can you use more than one D2B at the same time?
2)Whatabout working in surround, if the D2B is a stereo unit only, what would be the solution?
3) Have you compared the summing sound to other summing buses? For eg;Analog-SSL,Api,Trident,Neve or Digital- Sony DMXR-100 or even an O2R?
I'm thinking that by the time you hook it all up together, the price for everything will be about the same for a nice used analog console or a Pro Digital board. Am I crazy for thinking this?

EJolson "What are you using for your individual channel D/A's BTW?"

2 x AD-8000 Special Editions and an 888/16 to run some digital reverb/FX AES i/o boxes I have in and out of my DAW .

:)

" I have certain things hardwired to my outboard gear and others left open. I have a couple of questions about your setup though:
1)Lets say you are using all of your 16 outs, what do you do when you want to use more outboard gear?"

I must achive 'it all' (the mix) with a combination of plug ins (Sony Oxford if poss) and with in the 16 analog outs (configured stereo or mono)

"(multi compressors and Eq's, outboard effect processors that don't have digital ins and outs). Will you have to buy another Digi 888 or whatever?"

No I have the max running for the D2B - 16 (BTW I dont have more than 16 cool bits of outboard really! :eek: My set up is designed for tracking a rock band across 16 tracks, my outboard was purchased accordingly and some of it is of no use on mixdown (mic pre's etc)

"Can you use more than one D2B at the same time?

I think it's makers would sooner knock you up a custom model, thats their usual line of work anyway.

"2)Whatabout working in surround, if the D2B is a stereo unit only, what would be the solution?"

I dont know of one, but if you can think of an engineering need, someone, somewhere out there can build something to satisfy it I am sure!

"3) Have you compared the summing sound to other summing buses?"

Only to Pro Tools so far

"eg;Analog-SSL,Api,Trident,Neve or Digital- Sony DMXR-100 or even an O2R?"

Of those only a Sony DMXR100 and an 02R would fit my room....!

"I'm thinking that by the time you hook it all up together, the price for everything will be about the same for a nice used analog console"

The 16 input wireing aint that much $$ I dont need $2,200 worth of a second hand junk desk in my control room!

"or a Pro Digital board".

They start at $10K for the decent ones IMHO

"Am I crazy for thinking this?"

No, it's mixing with DAW that drives you crazy!

Hi Jules,

Yeah I've been doing it for years. My first experience with digital were the Mitsubishi machines. That went through the Sony 3348(16 bits) and the early Neve Capricorn. Back then I saw that I got the best sounds by running the tracks directly of the machine straight to the outboard, a practice I still follow to this day. By the way, I guess a good DA is important if you are doing this(Especially when it comes to using the Dangerous Box). And why are you still mixing to 44.1K? Give your mastering engineers a break why don't you. I think you would want the best reprensentation of you mix? If you are going to strap a comp to the mix or if they are going to do any treatment after? Food for thought.

Wow making music with 16 tracks!!! Does this really exists?LOL

Also, you only have 16 cool bits of outboard? I thought you were a certifiable "gear whore"? I guess we will have to classify you as a mere "gear slut". Sorry Jules.(Just kidding!!) With me its the opposite, I have I think (3)mic preamps, no microphones, and a whole bunch of mixing gear. I haven't mic'd a drumset(or had the desire to) in 7 years. I do track a vocal or a solo acoustic guitar once in a while, but that's it. No dealings with musicians, or cheap beer, or fattening fastfood. Nah, its just me, the mix, and the machines.

Guest Thu, 03/07/2002 - 15:26

So as not to diminish my rep as a gear whore, the L&R mix out from the Dangerous 2-Bus fed a pair of Neve 1073's with a tad of HF sheen and warm LF boost - going into an SSL compressor - into a Cranesong Hedd 192 converter - into a Masterlink at 24 bit 44.1k.

My junior engineer had mixed his first album and the act wanted my slant on the mixes, so instead of re-doing them in PT again we configured em to play back via the D2B. Without even touching much at all they sounded better via the D2B, then tweaking the key elements in the analog domain was a sheer joy and every one was much happier than the all in PT mixes that had been done.

Talking about analog summing vs digital, I have just heard Lynn Fuston's Neve vs PT mix CD, he compared the analog stereo output of the Oceanway 90 channel Neve desk mix bus on a 68 track mix converted to a 48/24 and 44.1/16 stereo master vs the same tracks imported into PT and mixed internally using the digital PT mix bus. Guess what, they are virtually identical. In fact I thought the PT mix sounded better after blinded experiments. I think it can be done and an analog mix path may only be beneficial if you want to use hardware outboard. It is the outboard that sounds better not the mix bus. This seals it for me having done blinded comparisons

Hi James,

Be careful with those statements, in some circles this is blasphemy. I was following the posts on rec.audio.pro and a couple of guys were able to hear the difference(Mixerman of course!!). I think all it proves is that:1)Some guys who have never worked on an 8078, can't tell what they sound like and don't know what it does to the sound 2)Blind tests mean nothing!!! It is what you do with your tools!!! Also the music has a lot to do with it. These were rough mixes done on both platforms, no EQ, compression nothing. Just a touch of the 480L. If it was a full mix, then I bet you would hear the difference. I think Mixerman said it best, if you are in the market to do just enough, than ProTools will get you there. But if you strive to create "magic" in your work than its a different story. I think society nowadays dictates and rewards the former not latter. What a shame!!!

I am sure you are right that with all the sexy outboard comps and EQ that an analog mix would sound better. The "blasphemy" you refer to is the idea that there is something inherently wrong with the mix bus of PT, I think the truth is that analog mixes probably get their magic from the advantage of high end outboard vs crappy plugins and that the mix bus is not the advantage over PT. this experiment has some people back peddling and I smell a sniff of defeat from some analog die-hards who felt that there should have been more of a difference. The tell tale sign of this is that the methodology of the experiment is now being undermined since most listeners probably cant tell an appreciable difference, so the explanation for this is that lynn does not understand Neves and so did not get the best out of it. i think this is insulting to Lynn and a cop-out for the fact that the mixes are virtually indistinguishable to my "reasonable " ears.

Hey Jules,

On a side note, what do you do when a client brings you a file on a different platform other than Pro Tools such as: Logic Audio,Cubase or Digital Performer? Do you transfer it over or do you not work with it unless its in Pro Tools? What if there is Midi with it, what do you then? I was just wondering because I know you are a Pro Control user and I am not sure it works the same with these other platforms. Thanks and Cheers.

mixfactory Fri, 03/08/2002 - 20:53

Mr.James Cullen,

I read your posts and on the most part I do agree with some of it. I've gone as far as doing an experiment where I sent a stereo mix through an SSL and a Mackie. I burned a CD of both, and asked people if they could tell the difference. Most couldn't, but this means nada because its just (2) tracks. I am sure if I had burned it from the Pro Tools itself, I would have gotten the same response. Had I mixed the tracks seperately then the difference would have been drastic. Lynn's experiment to me means zilch, cause in the real world you are either going to mix on one or the other to their maximum. He didn't, they were just roughs and no care was taken to maximize the strenghts of each. If this makes all of the Pro Tool users in the world feel better about themselves so be it. I know which I prefer to work on at the moment. This does not make me do a double take at all, only the fact the peoples ears are so use to the sound of "crap" that the quality doesn't stand out anymore. Have people forgotten the sound of excellent analog? IMO.

anonymous Fri, 03/08/2002 - 21:58

Have people forgotten the sound of excellent analog? IMO.[/QB]

I am sure you are right that those engineers who have had the privelege of working with great analog paths know that there has been a step down in quality of stuff they are hearing in the control room. by the time it ends up at 44.1/16 it has suffered a considerable degree of corruption anyway. So if you are comparing final master formats of analog and PT the difference is gong to be small on most domestic listening conditions. I do not have much experience of analog and do not claim my opinion means much, but I can hear stuff fairly well, and personally was expecting a bigger difference between the files. I suspect if I was in the Oceanway control room and had time to optimise the sound it would have sounded better on the Neve, by the time it got to my CD player in my car, I wonder whether the difference would be audible. Mixing and mastering engineers have the privilege of hearing the best audio only to see it smashed when its put on a CD. Most people out there never hear that. When LP was the standard, I agree the sound of a top end system vastly blew CD away. I agree with you that we have lost something, but mayebe it will come back with higher sample formats such as SACD

Ted Nightshade Sat, 03/09/2002 - 05:31

"When LP was the standard, I agree the sound of a top end system vastly blew CD away."

Where the CD really shines is in the worst case scenarios- unfortunately much more common than anything else. The cheapest CD player sounds much much better than the cheapest turntable or god forbid any cassette deck that's never had it's heads cleaned.
That's why some of us consider it a lifesaver- working hard on a cassette demo only to have it played back in a crusty car tape deck was a dismaying experience....

"what do you do when a client brings you a file on a different platform other than Pro Tools such as: Logic Audio,Cubase or Digital Performer? "

Import the files from a ISO 9660 (mac or PC) CDR PT can handle WAV. But the client is asked to make all files 'start from zero" and be 'whole' til the end of their part in the tune..

Then a blank session is made and you 'drag' the audio from the side window, onto the empty audio tracks...

As for midi, a file can be saved, burnt onto a CDR along with the Audio & read by PT somehow, that's one for the manual and my brainy young engineer / assistant !

I have learned to ask folks with Logic / cubase whatever... to record the FX they have set up at home.. That can save HOURS messing around trying to re-create some F£^$(@* delay FX made with a Logic Plug in or some such non PT FX. :)

anonymous Sun, 03/10/2002 - 05:16

Jules, have you had a chance to compare some mixes done in PT and those done at 48/24 via the dangerous 2-bus down sampled via the HEDD, I am seriously tempted to look at the 2-bus, my system is identical to yours, and my limitations for space similar, and despite my pro PT bias expressed here, I do think that some of my mixes lack punch due to plugins and possibly the mix bus, but I am yet to be fully convinced until I can do a proper A/B comparison in my studio. With your extensive experience I would be most interested in your conclusions on this. As for Lynn I have another of his CD's and his productions in PT are outstanding and have fooled some golden ears in the industry, so mayebe PT can get there with the right approach

Cheers

"I aim now to try tracking at 48k to squeeze a few more frequencies into the range." (me)

"Only to lose those frequencies, and more, when you do numerous sample-rate conversions. When will you people learn??"

Er.. what I mean is blast out my highest sample rate available - 48k - into my analog system (the topic of this thread) for eq-ing & compression outboard and summing then CAPTURING THAT ANALOG at 44.1k with another coverter.

This is fine, and there is no 'number crunching' SRC in sight..

A mastering house faced with 96k or 192k material would do the same thing - run that through it's nice analog out board the capture it with a great 44.1k converter to make the CD.

I proposed the same thing... I think that is fine... isnt it?

:eek:

Hmmm if you were able to organise some sort of 'non plug in' dependant session you might be able to swing by one day and do a quick test yourself at my place.. sessions depending... I am very behind on a lot of mixing :mad:

BTW you could just record the output of the D2B back into PT for future mastering..

That would be great, The Library looks like an exceptionally cool place. I have got an indie artist I am working with at the moment, ac guitar bass drums and keyboards. I try to record everything the way I want it to hear and minimise plugs because of the limitations, so mayebe when I have something solid, perhaps one song I know well on my system, at a convenient time for you we could do a quick A/B comparisom, it would be great to see your set-up. I m busy for a couple of weeks too, so I'll send you an email to arrange something if its OK with you

Cheers for the suggestion :w:

Hi Prod!

No because, the collective total (sum) of say, 8 drum tracks, feeding a stereo pair WILL be near zero ON THE PAIR!

Besides, as Nika the digital guru says, avoiding internal busing IS favorite, so skipping that and making the bus external can't be a a bad thing.

To isolate kick & snare & bass on seperate mono inputs to the mix is a comforting vibe.. I bet you would dig it on your pop dance prods...

It means (printing to Masterlink) me leaving behind my mix bus plug in favorites.. (so that is - analog mix of 48k material to 44,1 masterlink)

BUT YOU, however, could loop the mix out of the D2B back into PT (via your Track 2?) on 1 x stereo channel, (on record input) then listen to JUST THAT, with all your favorite plug ins on insert. so as you feel at home ;) ... print that when happy, (without commiting to the plug ins inserted on it), then adjust / fine tune them in a 'mastering session' later on, leaving some "scope" .

Phew!

Everything is possible!

anonymous Mon, 03/11/2002 - 06:06

Hi Jules,

I've been following along the various threads on your Dangerous 2-Bus observations...

One thing I've yet to ascertain; Have you done any direct internal PT mixbus vs. D2B comparisons, and (if so), to what extent have you carried the test (in other words, mixed both ways, mastered, and dithered down to 16/44.1, and burnt CDs to compare final, cumulative results)?

I realize you're currently enjoying "rediscovering your outboard" in a mixing scenario, but you would obviously need to run straight into the D2B to compare "apples to apples"...

I'd love to hear your observations on the differences and I'd be very interested to hear your impressions (as to what extent the D2B influences the outcome) of the final products.

Sincerely,

Guest Mon, 03/11/2002 - 17:20

We did an an initial test with no outboard in play, that was instantly impressive and we have been using it since.. , (but also running everything of L&R off a PT mixer on some overdub sessions that we haven't configured for the D2B yet this also acts as a comparison for us)
The D2B's first mission was to help us have a 2nd go at mixes for an album we had been doing. The newer mixes were better sounding in a profound, more that "just balance", fashion. This was clear to Artist, engineer & myself.
I have a big backlog of stuff to mix, when I am done with that I might get around to a 'fair play' off between the D2B & PT (but right now I dont want to do 'fair play', I want to do some good mixes!) . Knowing my rig for the last 3 years however, am convinced, the house engineer also.. One of those, "you had to be there" things...

ruder bolder bigger & more punch.

I have yet to do a session at 48 as I mentioned above..

Today I tried looping back from the Head into PT to two tracks in record ready & on input.

Mixing is more fun with the new toy..

:)

anonymous Mon, 03/11/2002 - 20:34

For somebody like Jules (and me to a lesser extent) who already have a nice collection of analog processors, I think one of the most direct advantages a box like that can have is in letting you do mults and use said (generally superior sounding) equipment easily without breaking the flow and creativity of a mixing session. You can add to this, at least, the sonic benefits of avoiding repetitive DAD conversions and the nasty little phase errors inherent in manual delay compensation and plugin processor usage.

As we can guess, this in itself can very much be enough to warrant a genuine improvement in the quality of the resulting audio, not to mention in the enjoyment of the mixing process!!! :D :tu: :w:

sjoko Tue, 03/12/2002 - 17:18

Just as a side note and very good sounding possibility:
I never bounce inside Pro Tools, but run everything that needs to end up on 2 tracks through a Lucid SRC9624 sample rate converter. I found this to be equally brilliant for sample rate conversions as it is an alternative for internal bouncing.
If you compare an internal bounce, or the above,you notice 2 things. The mix going through the SRC has much higher definition and an extended response in low and high frequencies.

sjoko Tue, 03/12/2002 - 22:19

:) That is why I said 'as a sidenote'

But yes, I do. I've become a 'use the SRC freak'
I got it because I found it to give me the best sounding dithering I had heard - in real time.
Second thing I noticed was when I had to time-edit a song already on a CD and, as it was in the chain already, I left the SRC in, so the audio just passed through, without sample rate conversion. I was surprised by what I heard, so I did it again without the SRC in the chain ... the quality was less, and I mean considerably so.
So, I got nosey and started experimenting. At the time I was working on a song with 41 vocal tracks - the ideal test kit. I solo'd one group of 8 vocals and bounced them within Pro Tools, and routed the same group through the SRC (at 24/48 without conversion)and imported them back into the same session. Once again, a HUGE difference in sound quality, what left PT came back at least as good, sometimes perhaps a little better (call me nuts - but everyone who's also tried it agrees).
I didn't understand why this happened and went as far as to call Lucid and speak to one of the engineers who designed the SRC, who explained that it was a fortunate side effect of the units design and that it had something to do with "re-alligning the clock and audio before the data left the unit" (in other words, I wasn't any wiser) All I know is - it has eliminated one 'bad sound' effect in my PT rig, and I couldn't live without the thing.

note - each piece of the rig is already clocked accurately.

sjoko Tue, 03/12/2002 - 22:45

I should add something, to avoid confusion.
One of the main reasons I now combine batches of tracks through the SRC back into PT in the final stages of mixing is to reduce track count and thereby sharply reduce the summing problem.

Its very easy to measure the difference, as routing groups through the SRC and importing them as 2 mono tracks (faster than an interal PT bounce) still leaves you all the original tracks.
So - its easy to, when you are finished with a mix, pull up all the tracks at their original levels, mute the bounced ones, and print another CD. Then you can really hear the effect of the summing problem, the more tracks the worse the problem
