The Visual Sound; The Josephson C700S at the Heart of Sound Liaison

At Sound Liaison, the Josephson C700S has become closely associated with our One-Mic recordings. But its role in our work goes much further than that.

Over the years, it has become one of the central tools in Frans de Rond's recording philosophy — it is the central microphone in the room, and it establishes the fundamental sonic picture around which the rest of a recording is built.

For us, the goal was never to use as few microphones as possible for the sake of minimalism. The goal is to preserve the natural relationships between musicians playing together in a room: their position, distance, dynamics, timing, and the acoustic space around them. The C700S gives us a remarkably convincing way of capturing exactly that.

One microphone, one coherent picture

The purest expression of this approach is our One-Mic recordings. The musicians are positioned around a single Josephson C700S stereo microphone, and balance is achieved largely through their own placement in the room. Move a musician closer and that instrument becomes more present; move farther away and it recedes naturally into the acoustic. Much of the "mix," in other words, happens before the recording even begins.

This has an important technical consequence.

One of the biggest challenges in conventional multi-microphone recording is phase interference. When several microphones pick up the same sound at slightly different times, those signals interact when combined — frequencies can reinforce or partially cancel, affecting focus, timbre, and spatial definition. Engineers can spend considerable time adjusting placement, polarity, level, and delay just to manage these interactions.

With a single stereo microphone, that problem largely disappears. There are no competing mic positions trying to reconstruct the same ensemble afterward — the timing and spacing you hear are the timing and spacing that existed in the room. The result can be extraordinarily stable: instruments occupy clearly defined positions, the soundstage has width and depth, and direct sound stays naturally connected to room ambience.

But this principle doesn't stop when we add more microphones.

Beyond One Mic: Carmen Gomes Inc.

A good example is Carmen Gomes Inc.'s Up Jumped the Devil, where Frans developed what we call a One-Mic Plus setup. The C700S remained at the center, establishing the fundamental stereo image of the band. Around it, Frans added two Josephson C700A microphones on vocal and double bass, plus an elevated, spaced pair of Josephson C617 microphones for ambience.

The reason was musical, not technical for its own sake. In a pure One-Mic setup, balance is set primarily by where musicians stand and by the dynamics they create themselves — that's part of its beauty. But Carmen Gomes Inc.'s dynamic range is considerable, and when the band opens up, the voice and double bass still need to hold their presence and definition. The additional microphones made that possible.

Crucially, they weren't there to replace the image created by the C700S — they were there to support an image that already existed. The C700S remained the foundation.

From One-Mic Plus to Scott Hamilton & Strings

The same philosophy scales to a considerably more complex ensemble. For The Ghost, the King and I, featuring Scott Hamilton & Strings, Frans again began with the C700S at the center, Scott positioned just behind it, capturing the fundamental perspective of the ensemble within the remarkable acoustics of Studio 1. Spot microphones were then added to other instruments where necessary.

Again, the purpose wasn't to construct a new stereo image in the mix — the C700S had already created one. The challenge was to add detail and presence without disturbing the soundstage the central microphone had established.

This is the key distinction in how Frans approaches multi-microphone recording. Instead of starting with a collection of individually miked instruments and asking how do we build a convincing stereo image from all of this? — we start by asking we already have a convincing image; what, if anything, does it need?

That changes the role of every additional microphone.

Adding rather than rebuilding

A spot microphone can give an instrument presence, definition, or tonal detail. But if it dominates, it can also pull that instrument out of the acoustic perspective the main microphone established — suddenly an instrument sitting several metres away sounds as though it's directly in front of the listener, and the ensemble's natural depth relationships start to disappear.

For Frans, the challenge isn't just making every instrument sound beautiful in isolation. It's making sure the additional microphones don't destroy the spatial information that makes the recording believable in the first place.

The C700S becomes a reference point. Where is the musician? How large does the instrument appear in the room? How much direct sound should we hear, and how much acoustic space should surround it? And, crucially — does adding the spot microphone make the recording more convincing, or merely more impressive?

Phase coherence as a musical quality

Phase coherence can sound like an abstract technical concern, but its consequences are easy to hear. When spatial and timing relationships stay intact, instruments occupy stable positions, transients keep their focus, and the acoustic around an instrument feels connected to it rather than added behind it. The listener can perceive not just left and right, but front and back.

This is a large part of what we mean at Sound Liaison when we talk about the visual sound. We want you to be able to close your eyes and see the musicians — not because we've artificially exaggerated their positions, but because the recording has preserved enough of the original spatial information for your ears and brain to reconstruct the scene. The C700S has proved particularly valuable in achieving that.

Encouraging the ensemble

There's another side to this that has little to do with specifications or recording technology.

A central microphone changes the way a session works. With musicians gathered around the C700S, the balance isn't something left entirely to the engineer to sort out afterward. The microphone encourages the musicians to listen keenly to one another, interact dynamically, and create the balance together as an ensemble. They respond to each other, to the room, and to the physical presence of the other players — rather than several individual performances being combined into an ensemble during mixing, the ensemble creates its own balance as part of the performance itself.

Drummer Bert Kamsteeg describes what this does to the experience of playing:

"For me, it's all about the 'image' — it's as if you can 'see' the individual band members within the stereo field, and it creates the sense of a real band playing in an open, 'homogeneous' space. This recording method enhances the 'band' feeling, making me focus on the whole rather than on myself as an individual, which I tend to do in multitrack recording. I find this approach far more enjoyable, as it's ultimately about capturing the essence of the group."

That observation goes to the heart of why the One-Mic approach matters to us. The coherent soundstage isn't only something the listener experiences — the recording method itself shapes the way musicians listen, interact, and perform as a group. Even when additional microphones are used, we try to hold onto as much of that philosophy as possible.

Not minimalism for its own sake

We don't believe one microphone is automatically better than ten, or that fewer microphones automatically make a better recording. Every session presents different musical and acoustic challenges.

What working extensively with the Josephson C700S has taught us is something more fundamental: begin with a coherent acoustic picture, and be very careful about disturbing it.

Sometimes the C700S is the entire recording. Sometimes, as with Carmen Gomes Inc., it's the heart of a One-Mic Plus setup. And sometimes, as with Scott Hamilton & Strings, it provides the spatial foundation for a much more elaborate microphone setup. The principle stays the same: preserve the natural timing, positioning, and interaction of musicians playing together in a real acoustic space. The technology should serve that reality, not reconstruct it.

Perhaps that's why the Josephson C700S has become so important to Sound Liaison. It's more than the microphone behind our One-Mic series — it has become one of the principal ways we pursue the idea that has guided our recordings from the beginning: to close the gap between what is captured live in the studio and the final master.
