RETRO MEET MODERN
RetroChannel is a new hardware based channel strip developed by Lance Keltner, industry recognized tone-master. As a lifetime musician, Lance grew up working in studios on Analog gear. He knew the best sounds were produced by very rare, very expensive vintage equipment.
Lance developed RetroChannel to capture the sound of these vintage signal paths in an affordable, modern 2 rack channel strip. The vintage signal paths Lance chose to replicate with the RetroChannel were inspired by the Telefunken V72 mic pre, LA2A compressor and Pultec EQ. Lance found a magic sonic alchemy that added depth and definition to vocal tracks, and gave drums more gain and snap ever before.
The Preamp section of the Retro-Channel is very flexible and provides everything from 0 to +42db of gain. It will run the pre warm and clean, or push it hard while controling the final output with the compressor/limiter and EQ on the unit. The compressor provides both limiting and compression. The EQ section has tweakable center points much like the vintage EQ''s. The Retro-Channel comes equipped with phantom power, instrument and mic inputs and a defeat switch for the EQ section.
