Cables for the sound-recordist from ETK Cables

March 2, 2025
Is there a collective noun for cables? A tangle of cables, perhaps? Well, here’s a tangle of a few of my sound-recording cables – all these made by ETK Cables.

Although one of the unsung parts of the recording kit, cables really do matter. I don’t mean in the over-the-top sense, such as where hi-fi audiophiles can spend thousands on a pair of cables to their speakers, but in the more down to earth sense that they must be well-made, of decent quality parts that last, don’t get stuck in your gear, aren’t susceptible to interference, and, of course, are suited to the job in hand. Like many, I make up a lot of my own cables, always using good quality connectors (invariably Neutrik for XLRs) and cable (mostly Van Damme, Mogami and Sommer), and often it can be a relaxing thing to do, with end result being a cable that exactly meets your own – perhaps rather bespoke – needs. Sometimes, however, I buy ready-made cables, especially when the cost isn’t much more than making up my own, I’m tight on time, or when the soldering seems a bit fiddly. I don’t just mean the effects of age on eyesight (though some reading glasses would doubtless help!), but also some of the cables I need these days seem trickier to make than just a straight XLR to XLR balanced mic cable: I’d be happy not to have to solder another little hirose connector! And on some occasions the parts are so difficult to get hold of that DIY is a non-starter: for example, just where are you meant to buy Sennheiser MZL connectors if not in the trade?

When it comes to suppliers of cable off the reel, connectors and more standard ready-made cables such as XLR mic cables, I have most regularly used Designacable (located in Nottingham); and when I have wanted something more specialized for recording (such as TA3 to XLR cables for my Sound Devices 788T recorder), I have used Pinknoise Systems (located in Gloucester). I’d recommend both very highly if you are in this part of the world. But lately I have been wanting some more esoteric audio cables, for which, if not making them up themselves, production sound recordists will seek out specialist industry ‘wiremen’ (I only heard this delightful term recently, so might well overuse it now!) such as, here in the UK, Stuart Torrance and Henry Smith. In my case, however, at the same time as I was needing a few more such cables, I became aware of another ‘wireman’ – Ed Kelland – who was setting up ETK Cables and introducing his new business on a few sound-recording forums. Ed worked for Rycote for a decade, until their Stroud factory closed (though since then he has continued doing some freelance work for them), so has impressive experience and, obviously, knows his way around the world of cables inside windshields: doubtless many of us have been using his handiwork for years without knowing.

Intrigued, I first bought a stereo split cable from ETK Cables back in July last year, to be used for a MS rig: it was, I recall, designed to suit my MS pair in a retrofitted Rycote Nano Shield. It was good value, made using good parts, and expertly put together. Since then Ed has made more cables for me and we have got chatting – batting ideas around about new internal windshield cables, new cables to then connect the windshield to a mixer/recorder, and even on the subject of his website (now redesigned, and making it easier for people to order all sorts of different variations – as well, of course, still being able to contact him for bespoke designs). It’s been fun and, I hope, helpful to support his new business in a rather modest way. Anyway, since ‘wiremen’ like Ed aren’t two-a-penny and as, what with his website shop, he is probably one of the more accessible ones (including to those not in the production sound industry), I thought it might be useful to some readers of this blog to run through the various cables he has made for me, which give a flavour of what ETK Cables provides and, in so doing, perhaps help the odd reader think more generally about their cable solutions – whether they continue to solder their own, buy off-the-peg or get bespoke cables made up by Ed or anyone else. It’s certainly good for recording efficiency, reduction of cable-borne noise, and reliability to have the right cables for the job.

Internal windshield cables

As I said, Ed’s particular background has been with internal cables for windshields, and this is where ETK Cables differs from, say, the excellent specialist cables made by Pinknoise Systems (where the emphasis there is on cables for connecting equipment – e.g. timecode cables). In my case, I have had four internal windshield cables made by Ed. My original purchase was a fairly simple mid-side (MS) split cable with full-size XLRs throughout: nothing very specialized about that, I know, as I’ve made several similar myself, including some with low-profile connectors. But following on from that Ed has made some rather more specialized cables for me, two of which have Sennheiser MZL connectors (i.e. the connectors that fit to Senneheisers MKH 8000 series mics, allowing the XLR modules to be removed and making the mics much more compact) and one of which has low-profile XLRs. The MZL ones are double mid-side (DMS) split cables: three MZL connectors joined by nice and supple Mogami 2697 cable to a Neutrix 7-pin XLR male (NC7MXX-B) connector. One of these has equal 18cm cable lengths, and is what I have been using when fitting DMS setups in the Radius Windshields Mini-ALTO 115. The second DMS cable is a more specialized one with different cable lengths of 17cm, 23cm and 31cm: it is for a native B-format array in my Mega-Blimp, and would be equally applicable to a similar setup with ‘vertical’ DMS mics with side-address cardioids above and below a horizontal fig 8 mic.

A DMS cable with equal-length cables to each mic, in this case using Sennheiser MZL connectors, but, obviously, standard or, more likely, low-profile XLRs would be an alternative.
The DMS cable above shown with MKH 8000 mics and my 3d-printed clips for the Radius Windshields Mini-ALTO. As an aside, you can see why I like MZL connectors, since they reduce the bulk of the mics, which always seems somehow less than ideal with DMS when configured this way – i.e. with two end-address (i.e. standard) SDC cardioid mics.
A more bespoke DMS cable with staggered lengths of Mogami 2697. In this case I specified that the numbering of the cables should be more like those in a Rycote windshield: I prefer channel numbers with white backgrounds (ageing eyes) and that don’t slide around!
The DMS cable with staggered lengths fitted for its designed use in the Mega-Blimp. A ‘DMS’ windshield cable, of course, suits any three-mic setup, such as the native B-format array here. As Pop Larkin would have said, ‘Perfick’!

The third internal windshield cable that ETK Cables has provided is an MS cable that Ed came up with, inspired by my MS clips designed for Radius Windshield’s hoops and, thus, also for the Mini-ALTO windshield. Ed’s idea was to use thin (2.1mm diameter) four-core and screen (i.e. stereo balanced) Mogami 2739 cable from the 5-pin XLR to the first low-profile XLR, and then a short second cable running from that to the second low-profile XLR. It’s a really elegant solution, reducing cables inside the windshield, making the cable exit less fiddly, and, at the same time, reducing cable-borne noise. It makes my previous conventional split cables for MS look a bit cumbersome and clunky now!

A stroke of genius, perhaps? Ed’s new MS cable, with just a single (albeit four-core and screen) thin and super flexible cable to the first low-profile XLR. Actually, while called an MS cable, it would be applicable to other stereo pairs where the rear ends of the mics are close together, such as ORTF (NB for some mics with ORTF there may need to be a longer cable between the two low-profile XLRs).
The same cable as above with a Rycote BD-10 and CA-08 MS pair setup in the Radius Windshield Mini-ALTO (obviously with the basket removed!). The single Mogami 2739 cable makes for a neater exit through the cable gland and easier cable management internally and externally. And it is much easier to use in a Rycote Nano Shield if retrofitting for MS: the cable routing there was very much designed for one thin cable only.

DMS breakout and stereo splitter cables

The above are just a few examples of specialist cables that are mainly for internal use in windshields (though could be used for bare stereo and three-mic arrays too), but looking at Ed’s initial website shopfront I was struck by the absence of cables that would form the next link in the chain: that is, taking the 5-pin XLR of a stereo setup or the 7-pin XLR of a DMS or similar three-mic setup and breaking out, or splitting, to individual 3-pin XLRs for each channel. It’s an obvious cable, but it’s surprising how few makers there are of them out there. Pinknoise Systems make some using Van Damme blue series multicore for stereo/MS and DMS. I have used their stereo one for a few years and love the easy coiling of the blue series cable, but the 7-pin DMS breakout version is not quite so appealing to me, being limited to 1.5m: for my use, that isn’t usually long enough to reach the recorder, and would lead to XLRs trailing in the mud and damp on the ground before you connect them up to single XLR cables. So Ed has produced a series of much longer versions using the same Van Damme cable, but, at the same time, utilizing the gold-pin black Neutrik XLR connectors. And he has done likewise with the stereo version.

A 3-metre stereo/MS splitter, or breakout, cable, with the robust, but easily coiled (or, as the makers say, ‘anti-kink’), Van Damme blue series multicore 2-pair cable. In this example I’ve gone for coloured rings on the XLRs to distinguish channels.
Another 3-metre Van Damme blue series multicore cable, but this time 4-pair for a DMS breakout cable, and with coloured boots on the individual XLRs to identify channels. Frustratingly, Van Damme don’t make a 3-way cable and, indeed, there’s nothing on the market that I can find that handles as well, so we just have to accept the redundant channel and the consequent extra overall thickness (Ø9.6mm vs Ø7.5mm for the 2-pair: not that big a jump). That said, the 4-way cable handles just as beautifully as its thinner stereo sibling.

For field recording I’ve long found the Van Damme blue series multicore absolutely spot on, and love going straight from a connector at the windshield to the recorder some distance away from the mics. Sometimes, however, such specialist cables aren’t the right length (and it’s hugely expensive to purchase a whole range of lengths) and you find yourself needing something much longer. Like many I have a much greater range of lengths of regular balanced mic cables for single channels, so on those occasions it makes sense to split or breakout from 5-pin or 7-pin to individual channels near the mics. With that in mind, Ed produces shorter cables using Mogami 2697, with a variety of lengths: I’ve found it very useful for the DMS one to have a staggered cable length option (cables of 17cm, 34cm and 51cm lengths) so that the three XLRs are not clustered together in an unwieldy bunch, but sit neatly against the stand or tripod one above the other.

DMS breakout cable, with thin Mogami 2697 cable, and again with staggered lengths.

In the course of our discussions about such cables in the autumn, Ed also suggested another option, which was to have a DMS breakout cable using the same Mogami 2697 as these short cables, but to protect the thin cable further with braiding. The example I have has three 40cm cables, but there is no reason why a staggered version couldn’t be supplied.

Note that I have added coloured hoops to the 3-pin XLRs on the short cables (compared to how they are shown on the close-up individual photos above), to make channel identification easier: I should have specified this!

Final words

So there we have it: a fairly quick run through a few of the cables that Ed at ETK Cables has supplied to me, to give you an idea of a few of the options available. Most of these have been added to his on-line shop, but don’t take the options in the shop as more than an intro: much of what he makes is like the output of other ‘wiremen’, which is cables tailored to the specification of the customer. Key things to think about when ordering (or, indeed, DIY-ing) cables, beyond the parts used, are the exact lengths (just how much slack is ideal for that internal cable?) and how you want different channels indicated: on some of the above I should have specified coloured boots for easier use than numbers, but – as it is easy to do with no re-soldering required – I have swapped black for coloured rings on the XLRs. And if you do contact Ed (or any other ‘wireman’) for a bespoke cable, please try and be exhaustive with your specification. This applies especially if you are citing one of my setups with my 3d-printed clips, as otherwise, Ed asks me to try and decipher what is meant!!!

ORTF: working towards a minimalist approach

November 15, 2024

The near-coincident ORTF stereo pair has a huge following that extends way beyond the remit of the body for which it was invented – the Office de Radiodiffusion-Télévision Française – and long after its demise in 1975. The required 110 degrees angling of the mics and diaphragm centres at 170mm spacing can be set up with any stereo bar. Or you can always use the Schoeps MSTC 74 ORTF mic (or its predecessor, the MSTC 64), where the spacing and angles are built in. And if you don’t have nearly £3k to spare, there’s the similarly designed Superlux S502 at around £100. But, evidently, there are many that find setting the angles and spacings on a stereo bar too fiddly by far (it’s certainly harder to eyeball 110 degrees than a right-angle); many who don’t want to splash out on a dedicated (but inflexible) Schoeps solution; and many who want something of higher quality than the Superlux. As a result there are many dedicated ORTF mounts available for SDC mics. These include offerings by major mic companies, such as DPA’s CXO4000 (which can also mount an XY pair) and, more recently, commercially available 3d-printed options. Ostensibly neat solutions, these dedicated mounts hold the mics directly, and can then be fixed directly to a mic stand: attempts to introduce shock-mounts then become clumsy, typically using Rycote lyres for the whole rig (fixed on a stem protruding from the bottom of the ORTF mic holder, and at 90 degrees to the intended use: a real shot in the foot). Come to think of it, an effective shock-mount or suspension for the Schoeps MSTC 64/74 or Superlux S502 isn’t immediately obvious: a Shure donut perhaps?

ORTF using a standard stereo bar (the small K&M 23550) and the smallest lyre/hoop mounts that I know: the Radius Windshields RAD field edition mounts. Rycote InVision INV 6s would be a larger alternative. The red hoops are a test run of softer 55D shore ones, and will go into production soon in a more subtle dark green. This is a fairly minimalistic ORTF rig with properly set up shock-mounts, but there is no denying that setting angles and spacing is a bit fiddly.

With a 3d-printer to hand, I wondered about a neater solution, using mics mounted correctly in suspensions (as if, for example, using a pair of Rycote InVision INV 6s or, smaller, Radius Windshields RAD field edition mounts on a standard stereo bar), which would then be fixed to a dedicated ORTF bar: the best of both worlds. First off, I designed a simple mount with size slots to fit both Rycote lyres and Radius Windshield hoops. The latter can fit Rycote mounts, but not vice versa. The three slots to each channel allow a bit of flexibility in the placement of the lyres/hoops for different mic models. I added a cable grip at the rear to help isolate the mics from cable-borne vibrations and, for my personal usage, designed this to perfectly grip a Sennheiser MZL cable: in my usage the ORTF mount will be used for MKH 8040 mics with MZLs. Taking a more minimalist route with MZLs made me think a bit more about the suspensions and clips, so I ordered a pair of 19/20mm clips from Radius (much more minimal than their chunky universal clips) and a pair of their 8mm clips (designed to hold the rear of a Sennheiser MZL or a Schoeps Lemo connector). This works fine although there is a mildly disconcerting slope to the mics as a result of the centres of the two clips being slightly different (they didn’t originate as such a pair), but the ORTF mount can be angled freely anyway: for this the bar makes use of a Gravity Quick-Tilt Microphone Adapter (MS QT 1 B).

With the same hoops mounted on the 3d-printed ORTF bar.
And angled a bit to show the construction of the ORTF bar more clearly.

So far so good, but when talking to Simon Davies at Radius about the different centres of the clips, he suggested that I try the two clips individually: that is, use one hoop only (the curved profile giving the new hoops more stability when used singly than the flat lyres from his Rycote days), and suggested I try the 8mm clip only. That was food for thought, so with the ORTF mount I tested the following:

8mm clip with single RAD-2 (21b) hoop x 2 (the control)

8mm clip with single hoop 21b vs two 21b hoops with 19/20mm + 8mm clips

8mm clip with single hoop 21b vs 19/20mm clip with single hoop 21b

8mm clip with single hoop 21b vs 8mm clip with single RAD-1 (21a) hoop

8mm clip with single hoop 21b vs single Rycote lyre 72 shore

8mm clip with single hoop 21b vs no shock-mount (another sort of control!)

With structure-borne noise transmitted from a suspended floor via the stand, the 8mm clip with a single hoop 21b sounded the best: in my test it offers less transmission of the lower frequencies than the 19/20mm hoop (or the latter with two hoops and an 8mm clip in the rear hoop), which I suspect is due to the fact that the 8mm clip is holding the rubber element at the rear of the MZL rather than the mic body direct. I couldn’t really hear/see any difference between the RAD-2 (21b) and RAD-1 (21a) hoops with the single 8mm clip. The single Rycote lyre worked OK on its own with such a light mic, but, connecting to the mic body, again transmitted much more than the 8mm clip. The absence of any shock-mount was definitely much worse than any of the clip/hoop/lyre combinations, as one would expect! So the conclusion is that the single-hoop and 8mm clip is an excellent idea for an ORTF mount for static mics with MZLs (sans windshield: or, indeed, inside a large windshield).

So with these useful tests in mind, I quickly modeled and printed a shorter version of the ORTF mount, this time with just with two slots – for one hoop for each mic. With the RAD hoops set with the concave side forward (orientation of the hoops is irrelevant as long as opposing if in a pair), the MKH 8040 sits nicely forward of any suspension or mount that could have an acoustic effect, and the whole arrangement has a certain minimalistic elegance (though I say it as shouldn’t, as my great grandmother would say).

Here’s the 3d model of the mini ORTF mount/bar.
A view of the single-hoop ORTF mount, this time with the 62D-shore hoops.
The view from the rear: the cable grips are important to both stop transmission of vibrations along the cables, and also to set the angle of the mics. I was a little sceptical that the cable clips would do both, but testing very much shows they do. Obviously differently sized cables than the Sennheiser MZLs used here would need different cable clips in the 3d-printed mount, but that’s part of the beauty of 3d-printing: you can design something that works for you!

It was only yesterday, after having modeled and printed these different ORTF mounts, that I received the 55D test hoops from Radius Windshields, in their ‘Evil Red’ colour. I had suggested the idea to Simon Davies as with Rycote lyres I felt that many end up using too stiff a suspension for a lightweight static mic with no windshields – be that for indoor effects or for music recording. Both Rycote and Radius are primarily geared to production sound markets, and those using mics statically often forget this and that there is a substantial difference between the needs of a mic that is moving – often quite quickly – on a boom-pole or in a pistol grip (think of the momentum involved) and a mic that is completely static, and where the aim of the suspension is to reduce the impact of structure-borne noise transmitted from, or through, the floor and then through the stand. So today I tested the 55D shore hoops on the mini ORTF bar, and they reduced low-frequency transmitted sound significantly, which can be useful on those occasions where you do not want to roll-off the low end of the mic. The MKH 8040 mics with MZLs mounted in 55D hoops (in the eventual production colour of dark green) and the mini ORTF bar (which I will now 3d print in black) will make a very minimalistic, discreet and well-suspended pair that are quick to set to the ORTF configuration on those occasions when I steer away from my favoured MS pairs. Sorted, as they say!

Just for completeness, here’s my comparison of the effectiveness of the 55D hoops vs the 62D hoops:a useful reduction in low-frequency structure-borne noise for those occasions (particularly when recording music: think of organ recordings, or even a standard piano where the lowest note is 27.5Hz) where you don’t want to use a high-pass filter.

Obviously the ORTF mounts shown here are very much tailored to my use, with MKH 8040 mics with MZL cables, but just in case anybody else wants to 3d-print these ORTF bars (free of course!), here is a link to the larger version for two Radius hoops/Rycote lyres per mic and here is the link for the more minimal one for a single Radius hoop. For others with very different mics and different cables, perhaps this DIY project will give a bit of inspiration!
