Sonosax SX-M2 questions & Help
« on: January 13, 2006, 04:04:19 PM »
Hey all,

I have a sonosax here that needs a little TLC. I think the gain pots just need to be cleaned/tuned up... when adjusting levels there's a static type noise that only happens when adjusting. Who can fix this, any suggestions?

Also - i need to find an external power solution for the sax. Does anyone use 12v power for it? if so, where'd you get the plug for it and what are the pin connections? I would like to get or have a power cable made, and use it with external power.
Does anyone know can you power it off 12 volt and use the same battery to run an ad2k+?

any help is appreciated, and needed.

Thanks,
ian stone

Leegeddy built me an external power source using 2 9v Wal-Mart l-ions. It can power the Sax for 8 to 10 hours and is super light. It's just the 2 batteries with 2 power cords that terminate in a single male 4 pin XLR , and then a female XLR to SXM2 power cable.

I don't believe a 12v SLA will work, as it actually needs a full 18 volts for powering.

As for the cleaning, that appears to be a semi-frequent problem over time. Check the archive, because I remember several tips on DIY cleaning...

Supposedly they're sealed pots which means, at least in theory, that something like detox or another lubricant wouldn't help.  But I've heard some have had luck going that route.

Bill Drucklieb of Cinemasonics (former US Sonosax repair center) recommended first trying to heat the pots from the front with a hair dryer (or very carefully with a heat gun on a low setting).  This along with moving the dials might heat up the lubricant inside the pots and better distribute it.  At worse, the pots can be replaced if need be.

Nick - you only get 8-10 hours on the /LS2 with external batteries?  I can run almost that long on a pair of 9V alkalines.  The Lemosax is very efficient, certainly a lot more than my Beyer MV100 running Schoeps bodies.

Ian, I would def. go with Dwonks 10 AA sled.

He never updated that thread, but he ran it forever.
I believe he recorded a 2 day festy let it sit for a month,
and then taped 3 more shows off of Alkaline AAs from the $1 store. 8)

Cost about $4 to make, and that price is loaded with fresh batts. :o
Just gotta solder 2 joints. If you can't solder let me know and Ill make you one for free, takes 3 minutes.

Yep, like chucky said....about 10-12 hours (probably more but the voltage after that point drops to 13.5V and I feel safer when it is at least 14V) with those cheap alkalines you can get at Ikea for $2/10pk.

Just so you know, do not run this off a power supply that has other things hooked into the signal chain.  The Sax has some ground loop issues with the external jack.  Make a dedicated PS.

oh here's another question: might be stupid...


so in order to use it as an "ls2", you need a mod done to it and need to get a kcy cable, right?
Can anyone tell me how much the mod costs/where to have it done? and then if you do go this route, can you still use the sax to power regular mics (ie: akg 414's?)

its actually not my preamp, its my buddy's here in town. he has akg 414's. He doesnt' tape a lot so for some shows around here i'm going to try running my schoeps>sonosax>722 and compare it with straight schoeps>722 just for kicks

if the mod can be done and it can still be used as a 'regular' pre, i would consider getting it done...

Not sure if you can get them modded after the fact.  Once they are modded, you cannot use it for regular mics with bodies, only KCY 5 pin Schoeps stereo binder plug and L/R lemo plugs for older style LC3 Neumanns.  I think that Sonosax does not make them regularily, they must be ordered and then custom made in Switzerland (takes a few weeks).  They are $1200 retail, and I have heard they can be had for less thru other channels.

I've ran it a full 8 hours and only had 1 of the 4 lights out on the l-ion batteries...never ran any full tests, so it's likely more like 30+ hours.

I'd love to see a CMC64>SX-M2>722 vs. CMC64>722 comparison.  Yell if you get around to doing that, or anyone else for that matter.
