The Studio Channel from PreSonus delivers great sound for virtually any type of recording or live music. Featuring tube preamplification, a VCA-based compressor, and three-band EQ, this channel strip delivers a huge variety of timbres. Produce luscious, in-your-face vocals, dynamic acoustic piano, and fat, solid bass guitar, not to mention crystal-clear acoustic guitars and cracking snare.

From slap bass, to snare drum, to vocals, the Studio Channel’s compressor allows you to record blazing-hot signals with accurate dynamics control. This channel strip’s three-band equalizer gives you the precision to carve out unwanted frequencies as well as tailor your tone to enhance your sound. Custom-designed amplifiers deliver sweet-sounding gain and cut for smooth highs; deep, solid lows; and clear midrange.
