The PreSonus Studio Channel is a specific type of audio interface called a “channel strip”. For those who are unfamiliar, this unit doesn’t work directly with your computer, but instead takes audio inputs such as microphones, line level devices, and musical instruments and allows you to adjust those sources before they are recorded by your sound interface.
This compact 1U rack-mount device combines a tube preamp, VCA compressor, and three-band EQ into a single, powerful audio interface.
The PreSonus Studio Channel is a decent proposition for multiple uses cases, from smaller home recording studios, post production and even less demanding broadcast environments. It has a great price point and a fairly comprehensive feature set that makes it useful for musicians, podcasters, streamers, and content creators seeking quality sound.
