The Kramer HLS Channel from Waves is a plug-in that models the microphone preamp and EQ section of a ’60s Helios mixing console. The plug-in was developed in association with producer/engineer Eddie Kramer, a prominent engineer at London’s Olympic Studios and who used their Helios console during a period that yielded many classic rock n’ roll recordings.

The unique behavior, coloration, and drive of the Helios console’s preamps were modeled along with the equalizers, renowned for their sweet saturation, high-end presence, and fat low-frequency boost. For added authenticity the console’s inherent noise and hum was also included. The plug-in also features a precision-modeled VU meter that recreates the sensitivity, ballistic behavior, look, and feel of the original.
