Out of interest, I put the power supply in the room with the mic and switched between polar patterns while the mic was on. The omni-directional pattern does drop the output of the mic a bit and I even noticed it picking up a bit of ambient noise, but having my vocalist sing closer to the mic fixed this issue easily. This might seem like it will cause noise on the recordings, but I find that it actually creates a nice blend of the acoustics in the room. This opens up an opportunity where you can record two vocalists at the same time on the mic. In the figure-8 pattern, I found that the mic rejected the room sound quite well. At certain high notes, the presence would also become slightly saturated.

I find the thickness especially noticeable at the lower mid-range with a nice warmth as well. The best way I can describe the sound of the WA-47 is colorful and thick, almost syrup-like. Moving on to the real important business in the WA-47 - the sound. So, you just have to sort of make sure nothing happens to the PSU. It is an IEC grounded PSU, but I still find it to be a bit inconvenient to tie the pattern switch to the PSU. The only thing that annoys me about the WA-47’s construction is the fact that the mic’s polar patterns are switched through an external power supply. I always appreciate it when a mic comes with a nice, sturdy box for storage instead of a flimsy cardboard packaging. I guess it is just a testament to the dedication and skill of the Warm Audio engineers.Īll of this excellent craftsmanship is kept in a nice wooden box. I am actually quite surprised at how Warm Audio was able to keep up such a high build quality while keeping the mic’s cost so low. This is the heart of the mic and what really gives it the U47 sound that makes it so appealing.

On the inside is a custom-made capsule that is tuned using two vintage U47’s. While it has some weight to it, I didn’t find the mic to be heavy. The shell is made from brass and plated with nickel.

The first thing I noticed about the WA-47 after taking it out of the box was just how sturdy it felt. This means that I expected the WA-47 to live up to that standard and be a standout U47 clone before I even started testing it, and I think I can confidently say that it does. Warm Audio is known for recreating vintage gears like compressors, EQs, and preamps to a nearly identical degree, and their mics are no exception.
