Attachment Deleted I'm thinking about replacing a cheap 24V DC SMPS with a 24V LPS for my w295b rack but the problem is the rack is using a 4 pin XLR connection as its power inlet and the output of a 24V DC SMPS has been changed accordingly to cope with it but when I had a quick look at the connections it seemed a little unusual as there were 4 wires coming out of the 24V DC SMPS (shouldn't there be 2?). I've included a picture of the 4 pin xlr for you to have a look. 2 white wires are connected to 4 and what looks like a -ve terminal (black wire) and ground(?) are connected to 1 of the 4 pin xlr. If I was to replace this 24DC SMPS with a 24V LPS that has a 2.1 mm * 5.5 mm output how should I wire them?

You should consider an LA3A or Serpent Chimera. I have considered (if I can save up the pennies) getting the Serpent Splice MK2 and the Chimera to give me some great options. I think I will get a JJ 6386 and see if I like it - I'm definately up for experimenting with valves - although my unit does sound great as it is, but you know - if might be even better? Do you run your 6386 as an added valve or do you remove the vavle(s) it can replace (if you see what I mean) To be honest as the Retro has no manual I'm not sure at this point which valve(s) it is meant to replace, I'm guessing it's the two inside the unit which do the MU compression bit of the circuit? Correct. Two 6BA6 valves inside are doing what a single 6386 should be doing so if you wish to use 6386 then you should remove those 6BA6s first. But when I enquired Phil about this he told me that his unit can be used with both 6BA6s and 6386 installed so it's up to you really.

my love for sta level is still strong. Tried a few other different tube compressors over the years but always found myself coming back to it time after time. There are many good tube compressors out there but none of them can do what sta level can do.

A pair of Siemens W295B. They will be here in about a week. Can't wait to try them!

Pye, crane song, dw fearn, great river to name a few. Yeah, but I hear they all suck. Trakker is PWM? I'm familiar with that, but it's doing a Swiss Army knife thing. Which I'm guessing the Pye might not be. Cheers, Geoff yeah they all sound pretty horrible not sure about the trakker I was referring to their stc-8.

Common single-phase US power is distributed at 240Vac which is then split into two 120Vac legs by a center tap transformer. One leg is inverted from the other. There is no actual phase shift, but it is standard jargon to call them "phases". 3-Phase Ac power does have actual phase shifts, but that's not relavant here. These two "phases" can be supplied to a facility. Smart studios will isolate non-tech loads (lights, hvac, etc) on one phase, audio tech loads on the other. This helps minimize noise and interference. Theoretically there should not be any power quality difference in either phase. They both come from the same transformer. If there is a problem, it might stem from interference and noise manifested by poor wiring/interconnection/circuit choices between the phases. It's in the implementation. Be careful not to confuse AC power phase with audio signal polarity. One has nothing to do with the other. Exactly. In our country, I don't think we even use a center tap transformer. So I guess I can safely disregard an idea of a single phase power outlet having a 'polarity' or 'phase' and having a neutral and live wire inverted shouldn't make any difference as long as the gear I'm using has a proper PSU circuit built in it.

In the old days of two-prong, non-grounded receptacles it was possible to plug in a two-prong power cord "backwards" and everything would still work, although at an increased possibility for a shock hazard. This was because "hot" would be on everything that was supposed to be "neutral", and vice-versa. There was nothing on the receptacle or the power cords to designate direction or polarity. You can see this on old guitar amps. Sometimes flipping the cord cap in the receptacles would minimize noise/hum. After a while devices were manufactured "double-insulated" to reduce that shock hazard. Also, as time went on, receptacles were manufactured with one slot larger than the other and the plugs on the power cords were designed to match. The larger slot designates the "neutral" current-carrying conductor while the small slot designates the "hot" current-carrying conductor. And of course, at some point in time, a grounding pin was added which results in the modern three-pin receptacles and cord caps that are in use today, at least here in the United States. But be aware - just because a receptacle has a grounding pin does not mean that that point of utilization is properly grounded! It should be noted that "neutral" and "hot" are NOT THE SAME as positive and negative. This is a common misconception. There is usually more line "noise" on the neutral than on the hot. This is because all of the return current throughout the premises is picking up garbage as it flows throughout all of the various circuits throughout the building. All of the neutrals are tied together at the service panels and this tends to amplify all of the line noise. ( this is a very, very simplistic explanation ) We've all heard that our audio power source should not be on the same circuit/phase/leg/etc. as florescent lighting or lighting with dimmers or appliances such as refrigerators and the like. So, with regards to audio equipment, if it's possible to plug in a device "backwards"- as described above - , then it's possible that that device can pick up more line noise and not operate as efficiently or quietly as designed. I think this is what is being alluded to on page 8 of the user guide. However, they are using the term "phase" erroneously. And, if the premise wiring is correct, with a properly installed three-prong receptacle, this should be a non-issue anyway because their device is manufactured with a three-prong IEC power connection which (should) make it impossible to be plugged in and powered incorrectly. Basically, what they are saying is make sure your point of utilization is wired correctly. Thank you. Your explanation is basically what I've learned in my first year at the university so it's good to know that I haven't mistaken anything. I thought it was very weird of them to say something like 'phase' or 'polarity' while dealing with a single phase power supply. But how would plugging in a device 'backwards' induce noise in any way? I mean with the way the rectifier and transformer works I see no issues with having a device plugged in 'backwards'.

"on the page 8 it says 'The phase of the AC supply can make a significant difference to the sound" Wouldn't the phase of an AC line not matter after the signal is converted to DC in the gear that we use? Maybe I'm not understanding the question correctly? I can hear a 50 sample nudge when messing with drum/bass gtr relationships. Its usually the number I have my nudge function set to in PT. 20 samples is insane haha. I don't think I'd be able to pick that up. Exactly my thought. As a matter of fact, I've never seen a downstep transformer having a 'phase' or a 'polarity'. Also, in my country most households use a single phase power outlet so I really don't get this AC 'phase' or 'polarity' thing.

I thought it was a stripped down version of their vari mu compressor? Input switch is a bit weird.. I guess the user will have to adjust the level going into the compressor.

If you wish to sweeten your mix (adding a touch of low and top ends) + pseudo limiting + a bit of saturation to bring out an edge try the overstayer MAS. It's been on my main buss ever since I purchased it and all I can say is that it is stunning. BTW, I'm not a fan of an eq on 2 buss and I usually leave it to the mastering engineer.

Hope it's not one of those we've already chosen who's going to win (someone famous or who have purchased a boat load of our products in the past) but we would like to advertise our product at no additional cost so... have fun believing that you're actually going to win this thing! HAHA! type of competition Uhhm yeah but no, It's purely random, everyone whom enters has a shot; take a look at the past winners. Good luck! I'm not saying this one is but I've seen some shady ones in the past so just wanted to clarify. Good to know and thanks!

Holy Shit! Listen to this. Dallas sent this to me...it's a clip from the C12 they're making. So - same capsule as the 251. The clip is from two years and several revisions ago...but this is really, really impressive if you ask me. That top is pretty damn unbelievable. if this vocal take is unprocessed then I completely agree with you.

great river mp500nv allows you to choose between 600 ohm termination and non termination format. Didn't know that heritage units aren't terminated.

Yes, I've read the HAs response but you've also read the response from Carnhill sales manager.. So... Carnhill is NOT a Marinair !!! and I like the Heritage (OEP) sound much better then the lifeless, sleepy, low mid bloated Carnhill IMHO. Same here. I have nothing bad to say about the quality or sound of their product. I just want them to clarify this issue once and for all.

Good information. I think Mr. Riley spoke without too much knowledge in this matter and Mr. Huart gave him more credit than he deserves. But even then the input transformer issue still hasn't been solved.. According to Heritage Audio it has...

Here are the "Chinese" switches apparently use in the Heritage 1073 and only worth a "few cents" according to Mr Huart's video. Blore Edwards Type PXR rotary switches... www.blore-ed.com/#!type-pxr/agp8g "The Type PXR is a robust and versatile rotary switch. Used in a variety of applications it is particularly suited to high-end audio applications such as the vintage Neve modules..." I don't know about you but the switches in this Heritage 1073 look very much like Blore Edwards Type PXR switches to my eyes. And the history of Blore Edwards... www.blore-ed.com/#!history/f6w7i "Blore Edwards is a UK Manufacturer and distributor of passive electronic components for a number of industries, including Pro-Audio, high-end test and calibration equipment and Mil-spec switches like our Type 72 and 142 (formerly the Painton Multibank)..." From the Heritage website: "The rotary switches we use are Elma Switzerland and Blore Edwards U.K." Looks like unwarranted fear mongering if you ask me. I think a correction is in order. Good information. I think Mr. Riley spoke without too much knowledge in this matter and Mr. Huart gave him more credit than he deserves. But even then the input transformer issue still hasn't been solved..
