A Studio Super-tool!

The Dangerous Music Liaison puts the fun back into trying out creative combinations of gear. The Liaison also lets your setup remain absolutely flexible — just what you need if you want to survive in a market that often demands recording, mixing, and mastering services from a single studio. The Liaison's claim to fame is that it combines your favorite pieces of music gear together in various configurations, allowing you to try out new gear combinations and recall them later. But there's a lot more to the Dangerous Music Liaison than mere signal routing.

Mix, match, store, and recall all your favorite gear combinations

Dangerous Music has always been dedicated to providing serious engineers with the most useful gear possible. They've upped the ante again, with the Liaison. The Liaison lets you experiment with different combinations of gear, giving you a total of six discrete 2-channel inputs and two 2-channel buses. Want to hear how that compressor sounds pre- and post-EQ? With a Liaison, you can audition various hardware combinations as easily as swapping around plug-ins in a DAW. What's more, you can store and recall your favorite setups, so you can keep that killer vocal compression chain or that thumping kick drum processing path close at hand.

Flexible stereo buses give you advanced configuration options

When we ran the Dangerous Music Liaison through its paces here at Sweetwater, we found that its stereo buses do more than just compare two discrete signal paths. Depending on how you configure them, these stereo buses can provide you with two completely independent, flexible signal chains, each serving as its own small routing matrix. You can also combine both buses to create a long and flexible continuous signal-processing chain, in which you can reorder entire sections of your gear setup. Even cooler, you can use the Liaison's buses to establish complex parallel signal processing — opening up limitless sonic possibilities.

Mastering-grade components for unrivaled sound quality

As is the case with all Dangerous Music products, the Liaison is made entirely from mastering-grade components, so you never have to worry about audio coloration or latency. In fact, when set to simply pass audio, professional grade testers used to measure the Liaison read as though they were plugged into themselves. Talk about quality control! Here are some of the other specifics. Both the inserts and the buses feature straight-wire, unamplified, balanced signal paths. All audio is relay-switched via top-quality, gas-filled, bifurcated contact relays — ensuring that all switching is absolutely noiseless. The rest of the Liaison's signal paths feature mastering-grade components made by THAT Corp. and Burr-Brown.

What the pros are saying about the LIAISON:

  • "The Dangerous LIAISON feels like engaging light-speed for my workflow...and make no mistake: workflow IS sound. The sheer speed at which you can do critical comparisons of entire signal chains does have a direct and positive impact how your music will sound." — Alberto Rizzo Schettino (Engineer)
  • "One of the best features of the LIAISON is the monitor outs...you can monitor the signal at four points in the chain: before and after Bus A and B. The usefulness of this feature is huge, and Dangerous deserves major props for including it! The switching of inserts is managed by beefy relays that are as transparent as any I've ever heard." — Adam Gonsalves (Mastering Engineer)
  • "LIAISON gives you the impetus to rethink how you record, mix, and master your music...[and] using the LIAISON is dead simple. I think of LIAISON not as an insert switcher, but as a creativity enabler." — Andy Hong (Writer/Reviewer)
  • "The Dangerous LIAISON is incredibly exciting. To have a device that lets you so easily switch between processors, swap the order of processors, do quick A-B comparisons of signal chains. It makes my work better!" — Jonathan Wyner (Mastering Engineer)
  • "Being able to switch devices from one bus to the other is extremely useful. The fast switching is amazing!" — Jeff Lipton (Mastering Engineer)
  • "The LIAISON is really important — I can do a lot of combinations of chaining gear and I am able to work a lot faster. Before the LIAISON [I had to] switch the patchbay and compare the sounds. Now I am 20-times faster than before, I like the way the LIAISON allows me to still be in the energy of the music. — Antoine "Chab" Chabert (Mastering Engineer)
  • "So happy with the LIAISON. Being able to switch gear in and out from the listening position without leaning over a patch bay is fantastic. After sitting in this chair for so many years, it actually improves my mixing ergonomics considerably." — Bob Power (Mastering Engineer)

Dangerous Music Liaison Features:

  • Flexible signal routing matrix that allows you to combine the gear in your studio in fun, exciting, and creative ways
  • Leverage all your gear, all the time
  • Improve your tracks, mixes, and masters by auditioning and marrying the perfect ensemble of equipment
  • 2 independent stereo buses mean you can set up 1 as a tracking path and the other as a mix path, without repatching, or chain them together
  • Separate parallel processing loop to let drums breathe and crush simultaneously
  • Create complex combinations of gear and A/B instantly
  • Store your favorite settings to recall any tracking, mixing, or mastering configuration
  • 6 stereo insert loops, assignable to 2 stereo buses
  • Mastering-grade components ensure silent, relay-based switching and color-free audio

What is Demo Gear?

At Sweetwater, we're so picky that what we call a "demo" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

What demo means to us is that we've had it out of the box, or maybe it was in a customer's hands for a few days and isn't "factory fresh" as a result. Every demo item we sell has Sweetwater's 2-year Total Confidence Coverage™ warranty, and has been tested and verified up to "new" specs by our factory-authorized technicians to make sure it's in perfect working order before we ship it to you.

When you buy a Demo item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Rated 5/5

Mixing and Mastering Center Piece

I have been using the Dangerous Music Liaison for a year now. My Sales Engineer Dustin Keesbury was so cooperative and showed me some great benefits of having the Liaison to facilitate my workflow. For me now, the Liaison is the most important gear in my setup because everything just revolves around it and it makes me only focus on the sound i want to reach rather than focusing on how would i disconnect and reconnect a certain gear in the chain
Rated 5/5

Can't imagine living without it now!

This thing is INCREDIBLE.

I work mainly in the box, but have a few high end pieces that I like to either track through or pass audio through after the fact - and this unit makes it SO so seamless.

I am a songwriter first, and having to patch cables in the moment is a nightmare because I like almost "set and forget" workflow to allow the flow to happen with inspiring sound - but with "set and forget" before, I would have to choose which to hook up to use for tracking, and which to hook up & use for running audio through from my interface / daw - and if I wanted the other, then go behind the units and switch around cables, no thanks!

I wanted to be able to use the same gear for both applications. Either running a whole song through, or with the press of a button applying the same gear to my vocal (or instrument) for tracking. This does that.

My setup is input of BUS A (only using one side of the input, Left, mono) is coming from my mic preamp.

Then both BUS B inputs are coming from my Apollo interface so I can send stereo stems or a whole song to it from my daw.

And then I have a mix of mono & stereo processors connected to the send and returns of this. The mono ones I use for the vocal, are connected via the send & returns, only on the side the vocal goes through (so in my case, Left ins and outs of the sends/return for those), and the stereo units connected just like normal (send and return L&R)

With this setup for example, I have an Unfairchild and this allows me to either run a full song through it via BUS B, OR by simply pressing a button and engaging it on BUS A instead - tracking a vocal through it. No more choosing either or, I can now utilize the gear I have for both applications.

This thing is magic. Before I pulled the trigger I emailed Dangerous Music to make sure it would work the way I was thinking (seemed too good to be true lol), and they were so nice & confirmed for me.

Can't imagine being without it now, would HIGHLY recommend for anybody with a similar need!
Rated 5/5

Great idea!

DM should build these in 1U strips as stereo/mono analog stem busses. Keep the in line and parallel chain options and add mix pots to each insert.

Liaison - Must-have for your Mix Bus

Another incredible purchase from my wonderful dealer, Sweetwater. The team at Dangerous Music are serious about audio and, like all of their products, the Liaison is an exceptional piece of hardware. The build is solid, the hook-up is simple and straightforward, and the contribution to my workflow is genuinely appreciated. With regard to my particular set up, I am routing the Buss A Out into the Buss B In (check out Fab Dupont's videos) as this allows further possibilities of combinations of your outboard gear across your mix bus. From the Buss B Out, I am going into two inputs on my Apollo x8. I need to move and mix quickly for the type of work I do, and the Liaison saves so much time not having to patch and re-patch to try out different colors and options. You will not be disappointed with this purchase. Thank you very much, Sweetwater and the crew at Dangerous Music.

Dangerous Music Liaison

DM always makes excellent products, I have 5 DMs in my rack,
The Liaison is very useful tool if you have outboard processors , 3-6 per say, and wish to compare how they work in chain.
Despite, it doesn't do anything with a song on its own, and looks very expensive,
it gives you immediate access to your eq, comps, etc, and even someone might think " I can do the same with a patch bay" , trust me , YOU CANNOT, so, a short word, have it, if you are serious about your final mix.
