Description

Product information "H2 Audio Helios Channel"

Mic pre, 3-band EQ, and classic FET compression — the complete Helios signal path that defined ‘70s rock, now in a rugged 19” rackmount channel strip. The H2 Audio Helios Channel delivers the full sonic DNA of the legendary Helios consoles in one powerful rack unit. Combining the 0011 mic preamp, inductor-based 3-band EQ, and the classic Helios FET compressor/limiter, this channel strip recreates the punch, warmth, and musical shaping that defined the golden age of British rock.
