I must say i have tried everything humanly possible to get my 2bus+ to work in pro tools with no success. surprisingly everything works perfectly in logic pro x. i just dont understand the deal with pro tools. I beleive there is something small that i am over looking. Any ideas on how to resolve this?

Hi! nice video. I am still confused how to set up my session for summing, though. I don't quite understand the printing part and why we need an aux before going to the master bus. Any suggestion where I can find info for this? Thanks in advance.

What do I need to connect a Dangerous 2 Bus? Can I just connect it to my Mac computer directly or through my Focusrite Scarlett 18i8i? Thank you.

Hi Fab Can you do a new video using the new 2bus+ with more details. Mixing any song but only using 2bus+ without any hardware.

I have two Apollo's, linked ,fire wire, so I can have 16 outs. Do I separate the stereo aux/buss ,to two mono, left and right? Thanks

How do I send a stereo track, i.e., a drum bus or an acoustic guitar buss, to the analog sum? I have the Neve, but I would imagine its the same process. Thanks Peter

@kozned: Any partially panned info will retain its position when routed to a stereo pair on the 2Bus. Not a worry

Hello Fab, I bought a Dangerous 2-BUS but am unsure how to implement it. Since many of my sources, say drums for example, and NOT either L, R, or mono, if I run them through the 2-BUS, won't it erase my panned stereo information?

Hi Fab My question about analog summing: if I route my BD, Snare, OH to the 2-Bus, how can I get them to a Drumbus in Cubase? I like to parallel compress my drums in Cubase. Is there a possibility to do that? Thanks!

@reymusic: Some people like running their stereo tracks thru the 2BUs just for its sound. I'm not sure how important that would be. It is nice to have the offsett button as a way to hit your mastering chain more or less hard though. Try and it with and without and see the tonal difference. Don;t forget that unity on a 2BUs is with the offset all the way to the right.

@scelza|: Yes you do have to be careful. If your interface glows red it's clipping you are probably loosing transients. The 2Bus gives you the ability to use the full range of many converters as opposed to just a apir but you still have to make sure you don;t abuse them.

Hi Fab, Im using the dangerous 2-bus LT with pro tools HDX.I Print my mix in Pro tools and export the Mix for Mastering..I have an external Analog EQ and Compressor that i use for mastering..My question is since i already used the dangerous 2-bus LT while mixing can i still use it again in my mastering before i go thru my EQ and analog compressor? Thanks Rey

Hi Fab, I picked up a Dangerous 2-Bus a few weeks ago and so far I'm really loving it. It's my first foray into the analog summing world. I'm wondering, do I have to be concerned with how hot my levels are coming out of the DAW into the 2-bus? For example, I have my drums coming out of output 1 & 2 on my HD i/o and I see the red lights on the front of the i/o coming on every once in a while and I'm wondering if it's possible to be clipping the D/A converter on the way out. Thx and keep up the great work. Loving your videos.

@reymusic: Assuming you mean CD 'recorder', the question to your answer really depends on whether you like the sound of your Rosetta AD or the sound of your CD recorder AD better. If the difference is meaningless to you then go for whatever is easiest and simplest. Simplicity always wins in the end.

Fab, Im using protools 10 hd and print thru my Cd player..I have pro tools with 2 bus LT and apogee rosetta 200 ..I want to know if i should use the 2bus LT Main output to rosetta 200 IN than rosetta 200 Out to protools IN..Or since i print to my CD player instead of bouncing 2bus Lt monitor out to rosetta IN than AES Rosetta to my CD Player..I don't bounce i use my CD burner to print my final mix.whats the best setup?Thanks
