You *really* have to be careful if you take up sailing.

Remember - Red and Green - Red = left and Green = right.

In the UK, Europe (and most of the world I believe) harbour beacons are marked red on the left when ENTERING the harbour.

In the USA beacons are marked red on the left when LEAVING the harbour - the opposite. :beamup:

If you are unaware you could be on the rocks. :beamup:
All of the Americas and most of Southeast Asia are in IALA (International Association of Lighthouse Authorities) Region B so, as you note, buoys are marked red on the left when LEAVING the harbour. I use the mnemonic "Red right returning" (from the sea). I assume the IALA regions have different marking schemes to help people who are like Columbus to avoid repeating his mistake. As the Tom Lewis sings in his great shanty Marching Inland:
"Columbus he set-sail to find out if the world was round,
He kept on sailing to the West until he ran aground,
He thought he'd found The Indies but he'd found the U.S.A.,
I know some navigators who can still do that today."

PS: I use the Neutrik XLR colour rings on my mic cables and follow the same protocol as Hugh and the Beeb. But when I use those unbalanced RCA twin cables that are coded red & white, red always goes to the right channel...go figure!

Edited to add PS: OK, Rycote shockmounts aren't cheap either but they're not expensive when you compare them to some (I might mention Neumann here ...) and they jolly well work.

They’re the badgers ;)

When I bought my TLM170Rs a few years ago my only really option were the EA170s that went with them...and at the time I also got some EA2124A for my KM series mics.

I’ve subsequently started using Rycotes for everything they’ll fit...and despite the money I’ve spent, saved myself a fortune vs manufacturer’s own....

Making these cables properly to genuine professional standards is very fiddly work.

The SOS ones use a surface-mount resistor and capacitor and are built uniquely for us by the Neutrik UK distributor to ensure they are of the highest quality and reliability.

Although this type of cable doesn't seem to be available from any mainstream commercial suppliers, some of the bespoke cable-makers will do them to order, although few build them correctly in my experience... If you're handy with a soldering iron they can be done DIY, but it's a real challenge to get both the capacitor and resistor in there!

Oh... and bear in mind that pseudo-balanced cables are only of use with synths that have grounded power supplies. If used with synths that have double-insulated supplies (most of those with wall-warts) it will usually make unwanted noises worse!

Having thougt about this a bit more, it occurs to me to ask if you guys intend to restock your own PB-cables in the near future?

Further to my earlier comments about US/JPN equipment, I think I really only have a couple of pieces that may cause issues - one is a Euro rackmount that's been converted to JPN at some point and has the power cable attached internally to whatever assembly they bolted to the back of the unit terminating in a 2-prong US/JPN mains plug. The other uses a wallwart (which itself accepts 110/220v (120/240v).

These would currently be connected to an RME UCX (balanced inputs) - the rackmount with the 2-prong gets its power from the Bronson stepdown transformer, don't know what that does from this perspective.

Like I said, I'm not currently (haha!) experiencing any issues re: hum / ground loops . . . but would like to have a few PB cables in the locker to (hopefully!) address any issues that may arise when I scale up my I/O and get everything hooked up properly.

Is this going to be a commercial studio? If not the I'd see how it all works when you have it patched together and only buy the 'expensive' cables if you have a problem. As a temporary fix why not buy an Art DTI for a little more than a pair of PB cables? It'll have many uses and be a perfect tool for diagnosing any issues you might have in the future.

No, it's my own personal setup Sam. I'm with you on not shelling out for unnecessary kit, not broken don't fix and all that . . . my intention here is just to have a few sets of PB cables in the locker should problems arise.

As to your suggestion, yeah - the little ART DI looks a worthwhile addition and I'l almost certainly invest in a / some DIs at some point, and in fact was just re-reading the SOS review of the ART a few nights ago.

The thing is, right now I need to buy leads anyway so I guess the minor (it turns out) extra expense of grabbing the specialist cables works out pretty cheap if you catch my drift. On the other hand a DI such as the ART will be hella versatile by comparison so absolutely worth consideration.

Cheers!

If you're looking at more than one or two special cables it's probably worth learning to solder so you can make your own -- and all exactly the right length too.

Right you are Hugh, and these days not just for making up special leads etc, but for constructing / assembling cheap(er) eurorack analogue filters and the like. Save a bloody fortune!

So I take it you guys aren't going to restock your cables any time soon then? I'm all for paying someone else to take care of fiddly soldering and placement of resistors and caps, after all! ;)

Well no, you won't save a fortune! Not at least for some time and unless you need a shedload of cables.
If you have no assembly tools at all at the moment you will need an investment of around £100 for 50W solder station, reel of solder (get 60/40 Lead) small table top vice, cutters, pliers and, most importantly, a testmeter. That last could be a Digital Multi-Meter (but get one that sounds for continuity) or your first job could be to make a continuity buzzer! Plus of course consumables, cable caps and Rs.

However, once so equipped you will also be able to repair existing cables and make specials for those odd setups.

Probably worth asking the question directly via the contact form at the bottom of the page. Not everyone at SOS spends time on here.

I quite agree, it's unlikely I'd ever save much on cables as I simply won't need so many as to make that much of a financial difference - I meant save a fortune by going the DIY / self-assembly route on eurorack filters and the like. It's in this area substantial amounts could be saved, just one or two such modules would pay for a decent beginners soldering setup, and I may require more than a couple for the project I have in mind . . . though that project is looking more dubious by the day as the source for waveforms to feed these proposed filters has proved to be a very poor investment indeed.

I wasn't aware we had run out when I responded earlier. We are now looking at restocking... stand by...

Thank you Hugh.

I figure I might as well try for the best technical construction as opposed to just a floating-shield job, and as a very longtime reader of both the magazine and the forums (30+ and 20+ respectively!) I'd like to support you guys where possible.

I'm so sorry for the delay in this.

It has transpired that our original manufacturer has decided they don't want to make bespoke cables any more, so we've had to find an alternative supplier which has taken a while.

I think we're almost there now, and are really just waiting for the green light from Ian on the finances to order a new batch and restock the shop. Hopefully it shouldn't take too much longer.

I'll update again when there's more news.
