Mackie makes some of the best mixers with reasonable prices! Their preamps are often considered higher quality than competitors. The ProFX8v2 supports up to 4 XLR microphones and up to 3 stereo inputs. The FX and Monitor sends can be used for mix-minus setups. Plus, the USB actually has an input volume control (missing from some competitors' products) and a “USB thru” feature to mix the audio from USB with the full stereo mix and loop it back to USB, which is great for live-streaming.
The only features the ProFX8v2 is missing are built-in compression and inserts for connecting an external compressor/limiter/gate. However, inserts are available on the slightly larger ProFX12v2.
If you need a mixer for podcasting, this is a great choice!
