    The Anywhere Channel.

    We named this channel strip the Studio Channel, and indeed it’s a wonderful studio tool. But it’s great for live performance, too. Featuring tube preamplification, a VCA-based compressor, and three-band EQ, it 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. Yes, we got the name wrong; we should have called it the Anywhere Channel. But we got the design right.
