- In this video I check out the Warm Audio WA-47 which is a take on one of the most iconic and sought after tube microphones of all time...the Neumann u47. Does it sound good? Does it give a different vibe to other mics? Is it built well and is it good value?

Great video. Thanks for the information. Very helpful.
Wa-47 is awesome bro!!
I want the wa-47 and the wa 8000 :")
I hope that you can share that videos, That will be so great!
A nice review looking at the WA-47 and very helpful to me for hearing some things before making a decision amongst Warm Audio's large diaphragm condenser mics for a specific application.
The power supply and the cable are extremely important to the stability of the circuitry of the microphone. The cable is really about two things.
First, the isolation of the audio signal from the power lines running in parallel to it plus the rejection of nearby electrical and electromagnetic noise. Especially for studio work. Really low noise high isolation balanced audio line is not inexpensive although it doesn't need to be the way over-hyped consumer marketed stuff that is sold to those whose deposit accounts are held by Fort Knox. Canare quad is an outstanding example of really good studio grade audio cable. It is not inexpensive but it also does not have a Fort Knox price point. There is another equally good audio cable I'd use although Canare quad is what I use when I make my cables. A nearly 100% coverage braided shield preferably with a conductive rubber layer to eliminate flex noise is not inexpensive to produce. Quad signal conductors inside would be ideal, but a single twisted pair will be adequate to get to the power supply. Hopefully, the power supply is running really well filtered DC including the tube heaters (filaments) which is not truly necessary in some applications such as table radios, but is truly necessary in a tube mic. Any AC ripple on the heater supply will, because it is a high current supply, will bleed into the audio line adjacent to it no matter how well shielded it is. Zero noise is too much to ask with even the highest quality solid state rectifiers and filter capacitors in the tube supply. There is always semiconductor junction, capacitor, and resistor noise. The better the audio cable, the better the end result.
Second, the gauge of the copper power conductors in the cable make a huge difference in the voltage stability of the circuitry in the microphone. Cheap cables use minuscule conductors. The tube requires a relatively high current for the heaters (filaments). A tiny gauge creates a resistance in the cable that creates a voltage drop between power supply and the vacuum tube. Not good for having the tube operate according to specification. A tiny gauge in the high voltage supply also creates a resistance in the cable that creates a voltage drop between the power supply and the vacuum tube. For the high voltage to be stable in the tube, the gauge needs to be large enough gauge (a lower number) to make the cable resistance nil compared to the tube resistance. Otherwise, the tube voltage will vary as the conductivity of the tube varies during signal amplification. The variation will correspond exactly to the signal amplitude. This is not good for linear amplification of the really tiny signal the tube is amplifying -- the amplification will be non-linear.
There is a budget C-12 clone that comes with an insanely poor power supply and cable. I have one. It has good internal parts in the mic circuit board. It needs, and I built one, a far better power supply. It also needs a different and much higher quality cable -- I bought one for slightly less than $80 made by a well-known and reputable maker. The price point is obviously reached by including a total junk power supply and cable with it. I may put Neutrik ends on the mic/power cable at some point. Simply replacing the power supply and cable with a really high quality one improves that microphone enormously and is immediately noticeable to an audio engineer. A dramatic improvement. I will probably replace the capsule with a much improved C-12 style capsule, but that improvement, whilst important, is nowhere near as dramatic as changing the power supply and cable. My take on this is that whilst it may seem some hype for Warm Audio to tout the cable, it is a very good one and it is worth noting considering the really bad total junk cables and power supplies that are sold with budget oriented tube microphones. It is worth noting that Warm Audio did not sacrifice this part of the microphone build for getting to a good price point.
Thanks. Would have been interesting to hear your compressed/EQed vocal as well.
Many thanks, regarding tubes…did you see Jim Lills video about where the tone comes from with mics?
Nice video Harv. On a separate note, what are you using for audio?? It sounds soo good honesty
Many thanks, ha ha I have basically the answer to this coming in my very next video! Scheduled to go live on Friday next week 😄
@@HarvVideoAudioStuff Ah you tease! Will make sure notifications are ON when that video drops haha
Enjoy guys 😊
I did my homework on this and found out that the original Telefunken U-47 cost €100 when it was first released. I'm NOT kidding!!
Which with inflation would be €3,283.44…
@@LiamHardyMusic Yeah, but the components/materials remain the same. An apple from 1940 should still taste the same today (different apple, same flavour)
@@Wilmer778 again, that's not how inflation works buddy...
@@LiamHardyMusic I'm not talking about inflation, hahaha. :P
this have its own power supply right? do i still need to use 48 phantom power in my pre amp or audio interface? please reply thank you!
Just in case you haven't found your answer yet, no you wouldn't need phantom power.
I own a Groove Tubes GT 55 mic, and Audient ID 14 interface. I'm thinking of getting a better sounding mic. Should I get a new mic or new preamp?
Always mic over pre!
What mic should I get. I was going to buy the WA 47.@@HarvVideoAudioStuff
It does sound nice straight away
How does the WA-47 compare compare to a $60 microphone?
Ha ha that would be a good test, I’ve just found a condenser mic on Amazon for £13. May have to snap it up!
Good work man, but consider using a de-esser for your narration.
Hahahaha There was some funny shit in this. I think it's a bit boomy. I think I'm gonna get a Warm Audio 87. Thanks good info
nah man don't get all " I know I know" when describing the capture, the other day I described my buddy's voice on the mic as "spreading butter" so...
47 sounds better, the highs are pokey and sibilant on the 184 in a bad way to my ears. works great for certain things of course, I think Cannons uses one or a 185 or 183 for their vox. Very specific hifi sound.
where do you have the wa47 placed on the acoustic guitar? it sounds great!
Would also like to know... distance? aiming at? it sounds soo good and it's unmixed.
Wanted to subscribe but my finger is hurting
JIM LILL THE BEST
Had this mic, was bad, was taking eq adjustments badly, tried to put the best tube possible and made no difference. It was good for classical guitar though in omni mode positioned close to the strings but even in this case it had an almost inaudible distortion resonating on the low freq. Sold this mic, stay away from it, at this price you can buy better ones.
Yeah tubes make no difference (no really). I’m sure what you meant to say was that it didn’t suit the source you were recording and you didn’t like it. Surely the sheer number of overwhelmingly positive reviews out there (including SOS) should mean something?
