RØDE RØDECaster Pro
This is the new ultimate podcasting mixer, recorder, and interface all in one! Connect up to 4 XLR microphones, easily mix-minus with calls through multiple devices, and adjust volume individually for up to four headphones! Plus, record in split multitrack to the storage card or to your PC via USB.
Behringer Xenyx 1204USB
This is the same mixer I started with. It’s great quality and highly versatile. This has enough inputs and outputs to support mix-minus, 4-channel recording to an external device, USB in and out (with monitoring), and more.
It also has built-in single-knob compression for the first four channels. (If you need to add an external hardware compressor/limiter/gate, then you’ll need a mixer with “inserts,” which this one doesn’t have.)
For high versatility, a multichannel Firewire/USB 2.0 interface, and even recording directly to an attached USB storage device, the Behringer UFX1604 is a dream mixer.
This beast supports up to 8 XLR microphones (with inserts) and offers up to four outputs for mix-minus.
