MK-U47; Tips for use , including pres and compression

I can say this for sure...I would not use a pre like the LA610 with it as it is already super vibey. Also it seems to me to have natural compression and with my MK47 I use no compression and I generally use cleaner settings on the pre (CAPI VP28 gain down output open.) Take this all with a grain of salt though as Im not an everyday professional but do have a great listening environment.

JMO/JME,
  i love mine with the vp28(i sold my N72's, J99's and rarely use my others, with that 4 chamber you'll definitely be cutting a LOT of bottom with a J99), I generally use it to cleaner settings with the vibey MK, i can always use the VP28 in line setting and run it through again smacking the input to squeeze it(yes the vp28 is the best "fit it in the mix" compressor i own, dead serious 8), the vp's range is so large it's silly. 
  As far as compressor choices, on the rare occassion i need one for tracking, i'll use a modded super invisible aphex 651 to patrol the peaks. I personally always decide what color and how to apply compression later, and in the context of a mix. 
  If you get your mic placed in a sweet spot, the air should compress nicely for you and smooth out dynamics, a lot of peeps somehow set mics in a rarefaction cycle, which makes you feel a need to compress during tracking, and that usually leads to trying everything to get a better sound later, and it rarely turns out great IME. I don't know about anyone else, but i never prefer the sound of a compressed acoustic guitar over an uncompressed, the only reason i do it, is to fit it amongst other instrumentation at mix time, otherwise... no way.(broken record style yo! 8)

so what i'm saying(i guess lol), is work the mic a LOT with little influence from anything else, and get to know it really well, the tubes and blueline in there will go a long way toward focussing/compressing right off the bat ime. It's hard to make it sound bad really, but if you add too much it can get tubby on you quick, especially with the 4 chamber.

yes, some units bog when they get loaded, i believe the old bae units suffer that?(cant remember?) I have 3-51x boxes, only the 1st is full at this point, as long as the power supply has enough horsepower to provide good amperage to all, you'll be fine, 16v +/- is what a lot of pro audio gear runs on ime, so there is no compromise in that regard, some will argue less features fit in a 500 module, and they're correct. The beauty of 51x is you can run 24v units. The 51x psu has upwards of 5amps of current available i believe, that is by FAR the most of any 500 rack.

sharp you are, i've got a couple things open in my CPS 750 supply, i'm probably going to hijack that for my 3rd box?

hey E, is the 24v section of the cps psu for the meter bridge? I assume it is, but cant seem to find it on the schemo's, and don't want to pull modules out to see lol, i need that on the cps750, but i have a cps650 for live applications that just utilizes the 17v rails, with no meter bridge, i could ad a power xlr and use it for both purposes, and have one of my 51x racks be 24v only? I plan on some NV73's, and gemini 86 tube pres @24v, so it would work great and save me some $ in that regard.


kcatthedog sorry for the hijack bud 8)

I think my Radial Sixpack provides 1600ma for the six modules, which is pretty over spec. Nice connection options as well.

MJb said "Good luck, I think you're going to be thrilled. I believe that mic will be as good as it gets for your voice."

thx martin as we have listened to each others trax a lot, your view and good ears means a lot to me.

I can honestly say all 47 uber status symbol Bs aside; that is teh one reason I did the mike and spent the money, in the simple hope that it would really suit my voice so my songs can engage the listener as much as possible!

tony adn e no probs; that's what I am here for, anytime, ah anythig else you guys need to discuss :0 I was trying to save a few bucks on a cheap 500 box and now youo guys got me back to buying a friggin console for the reserve psu; power WTF

otherwise know as gearhead purchasing logic, no honey, I really needed this 24 track console especially fro when I single track; honest ah did I measure it didn't come with converters,,, ah yet ?

winetree I don't have  budget for that pre but that is where I was going with my comment about the 7 circle diy jenson j99 as I already have the 2 hardy op amps.

Warning Gear Porn !

the 7 circle kit is about $325 (comes with di) and the one shot chassis is $150 ish, actually these are designed to fit 4 in a raxxass 19 panel too.


like everyone who looks at 7 circle, i considered the cost of the one shot in relationship to its 8 unit chassis and the get confused and then typically cstart looking at TSTCNBN classified for used  8 unit chassis and actually there was one just last week for $250 ish  and then you start looking at its new black chassis  !







since you guys are talking psu's, rails, volts you know all the electrifying topics ; here ya go the deets:

CH02 Chassis

The CH02 is a road-worthy 2RU chassis designed to hold up to eight Seventh Circle modules in any combination. High voltage supply rails enable more headroom than any 500-series rack. Illuminated logo indicates +30V, -30V, and +48V health. Universal input power supply runs on any mains voltage from 85VAC to 250VAC. Kit includes power switch, wiring harness, eight steel dividers, lead bender, a full complement of hardware, and more.

Order modules and subpanels separately

Chromate Zinc Finish Clear chromate over zinc plating for excellent grounding. Steel Dividers Includes eight internal dividers to support heavy modules. Unlike the aluminum tray of most 500 series modules, our heavy steel dividers provide superior magnetic isolation between modules. Easy Module Installation Split rear flange makes module installation easy. Complete Package Includes wire harness, toggle switch assembly, illuminated logo power indicator, AC line cord, hardware, and more. Internal Power Supply New low-noise PS04 power supply runs from any mains voltage from 85VAC to 250VAC, 50Hz to 60Hz.


J99 Microphone Preamp

The SCA J99 is a flexible, high-gain, low-noise, low-distortion microphone preamplifier, based on the classic Jensen Twin Servo design. This is a great preamp to use when a neutral sonic character is required, but the slightest amount of euphonic transformer coloration is desired.


The J99 requires two 990C style op-amps that must be ordered separately.




$329

Features

High Gain The J99 can provide 70dB of gain which includes the voltage step-up provided by the input transformer. Jumpered for 300 ohms input impedance, the maximum gain available is not quite 76dB. Low Noise With an EIN approaching -130dB, the J99 is quiet enough to use in virtually any recording application, especially with low-output ribbon mics. Dual DC Servos The J99 has a DC servo for each op-amp and uses no capacitors in the signal path. Stepped Gain Control A 12 position Grayhill switch provides accurate and repeatable gain settings in 5dB steps from 15dB to 70dB. Gain Trim Since 5dB is often too big a gain step, the A12 also has a gain trim control, which provides up to 6dB of cut at any gain setting. This allows very fine adjustment of gain between steps. Phase Reverse Inverts the signal phase. Phantom Switch Slow-rise phantom power minimizes pops and thumps. Neutrik Connectors High quality PC mount connectors eliminate cabling and ease assembly. Lundahl Input Transformer The J99 uses a Lundahl 1538XL to couple the microphone signal to the amplifier. This transformer is used in a number of high-end preamps and it provides superior performance in a compact package. Cinemag Output Transformer The CineMag CMOB-2H output transformer provides a balanced, floating output with extremely low distortion and wide bandwidth. Flexible Power Supply On-board voltage regulators can accommodate power supplies from +/-15VDC up to +/-35VDC, allowing the use of op-amps with +/-24VDC requirements. Potentiometers allow easy voltage adjustment, making experimenting fast and simple. Local regulation also keeps inter-channel crosstalk extremely low when multiple preamps share the same power supply. 2520 Compatible The J99 will work with a number of discrete op-amps from manufacturers such as API, Millennia, Forssell, Old School Audio, and John Hardy. High quality IC amplifiers such as the AD797 and OPA627 can be fitted directly to the board as well and can rival the discrete types when extreme headroom is not required.
