Overview

All Tube Vari-mu Compressor

The P.LANE Type 436 is one of the most unique compressors of all time. HERITAGE AUDIO and LANG ELECTRONICS Inc. are proud to present the P.LANE Type 436, all tube varimu compressor, our take on the illustrious modified version of the ALTEC 436C, that graced the fresh and furious British Invasion sound that conquered the world in the 60s.

This classic design has continued to gain popularity to this day due to its velvety, flattering character and its sublime ability to control dynamic transients without killing the high-end.

Used on a daily basis at the hottest studio in London for tracking bass and guitars, the defining sound of the Type 436 varimu compressor was extensively used when tracking guitar, piano, sitar, mellotron, strings, brass and woodwind by a particularly talented band from Liverpool and has set a gold standard for modern instrument recording up until today.

The P.LANE Type 436 thoroughly recreats the sound that defined an ear and set the path for modern professional studio recording. The legend of the modified ALTEC 436C is not just a myth from the 1960s. Due to its unique character and its simple yet flexible functionalities it has proven to be the secret sauce for many experienced contemporary producers and in almost any musical genre you can imagine (from pop to rock, alternative music, metal, hip hop, and even electronic music) when tracking instruments.

And no effort was spared in the designing process as the P.LANE Type 436 covers all development stages of the original, from the rather simple but incredibly effective model 436C, to the more evolved ”London Mod” with 6 selectable constants and “HOLD” positions for each constant, that will keep the source signal compressed to the most recently processed peak level. We’ve also taken it one step further and included the SuperFast setting, not found in the vintage 436C, that takes the unique character of the P.LANE Type 436 to a whole new level, adapting it to the modern needs of studio recording.

The P.LANE is one of the units that fall under the “Sound that defined an era” line that seeks to revive historical units that fit into today’s studios and were either unavailable or too overpriced.
