$10k on a Youtube content creator / podcast setup (4k camera, lens, desk, macbook, 32" monitor, mics, mixer, lighting etc). Even if I don't make money on it, I think it'll be pretty fun and lead to cool people connections and future friendships. @AboveAverageInvestor on YouTube. Just started 2 weeks ago. Feel free to provide helpful feedback if interested.
My suspicion is that you don't need anywhere near that much stuff.
Just looking at the audio side alone of what you're talking about . . .
- You probably don't need or want a hardware mixer. The input controls on almost all audio interfaces should suffice for setting reasonable recording levels, and the rest of the mixing you're going to be doing on your computer after the recording session.
- Figure out what kind of content you'll be creating to determine how many inputs/outputs you're going to need. My guess is that four mics is probably
way more than enough.
- Cheap microphones work just as well as expensive ones for most small setups. I'd take an SM58 over the ubiquitous (and much more expensive) SM7B that Joe Rogan popularized. The '58 will require less oomph from your interface pre-amps too (it's not uncommon for people running an SM7B to find that they need to buy external preamps or line boosters to get signal levels up high enough. Generally I'd recommend a close mic'd dynamic for the typical noisy room that podcasters are running from, but there are also plenty of decent quality cheap condensers you can go with. Rode NT1 or AT2020 are both quite usable for example.
- Might be personal preference, but I find two or three cheap/smaller monitors in a setup tend to be more productive than one big ass monitor. You'll be more productive if you can jump back and forth between multiple screens rather than trying to arrange and switch between stuff on a single screen all the time.
- You don't need to spend $$$ on a desk. The desk I've been using for music mixing for the past 16 years was found on the side of the road. It's a good height and has a solid extendable keyboard tray. Hit up your local dump and craigslist to pick something up for cheap. Sanding it down, and painting or staining/sealing the furniture will make it look exactly the way you want and hide most minor defects.
- You might or might not need a laptop depending on the type of stuff you want to do. If you don't, then you will be paying for useless portability and shorter component life. If you do, you definitely don't need a macbook. There are a wide variety of options out there that are cheaper and will work as good or better that should be considered.
- One thing I don't see in your list there . . . plan on getting a couple decent quality mic stands. There are some very good boom arm stands that can attach to a desk (if you're planning on doing most of your recording in one location), or you're probably going to be looking for a few quality boom arm tripod stands if the desk doesn't work out. Cheap stands have been a constant annoyance in my life for recording musical instruments. They are unreliable, and once you get stuff setup they tend to move/slip. They also tend to break easily. If you're not packing them around lots of different places then this is probably not a big concern though.
- Another thing not on your list . . . assuming you're doing this in a room in your home, you will want some acoustic treatment. Recording in an untreated room typically sounds like shit - lots of small room reverb, muddy lows and the reflections cause difficulty hearing upper frequencies with clarity. Using closer dynamic mics can somewhat help with this while doing the recording but if you're planning to mix in the same room you'll probably want to fix the problems. You can build some simple broadband sound absorbers for pretty cheap (they're mostly just wood, rockwool, and some kind of fabric to wrap around 'em), but you also need to know how to place them effectively in a room. If you're interested, I'd strongly recommend you go through the information on this forum -
