Heritage Audio LANG P.LANE Type 436

• The Return of a Compression Classic

Heritage Audio's LANG P.LANE Type 436 is more than just a comeback: it is an accurate revival of one of the most musical tube compressors in recording history. Originally based on the legendary Altec 436C, the LANG model was refined by Lang Electronics Inc. to offer more precision and versatility than the original design. Today, Heritage Audio has brought this gem back to life with an approach that combines faithful sound reproduction and optimization for the modern studio. Made in Spain from select components-including NOS tubes and custom LANG Electronics transformers-the Type 436 returns warm, smooth, three-dimensional compression perfect for adding depth, glue, and presence to any mix. This 2U rackmount compressor is the ideal choice for engineers, producers and studios who want to bring a piece of audio history into their setup without sacrificing stability, reliability and modern features. Precise Controls. Musical Compression. Vintage Feeling. One of the most beloved features of the LANG Type 436 is its ability to deliver musical and never intrusive compression, even at extreme settings. This is made possible by its intelligent controls and vari-mu tube circuitry, which reacts naturally to signal dynamics. Attack and Recovery (Release) controls offer 6 settings each, allowing you to choose the dynamic behavior best suited to the audio source. In addition, HOLD and SUPERFAST modes expand the range of applications-from gentle, progressive gluing to fast, effective compression for fast transients. The Threshold DC control lets you adjust the compression threshold by acting on the control voltage, while the Input and Output controls let you perfectly manage gain staging, keeping the signal always in the optimum zone. All this can be monitored in real time through an elegant backlit VU meter.

• Perfect in Mix and Tracking
• From Voice to Mellotron: a Compressor for Every Session

The LANG P.LANE Type 436 is designed to tackle a wide range of musical applications, whether during recording (tracking) or mixing. Its smooth, musical response, combined with harmonic tube coloration, makes it an indispensable ally in any audio chain. In vocals, it lends body, presence and dynamic coherence, enhancing details without ever sounding sterile or digital. On instruments such as bass, electric guitar, and strings, it adds punch, harmonic saturation, and glue. And if you use it on the drum bus, the result is a more cohesive, dense mix with a natural, engaging groove. Not just "classical" music: the Type 436 is perfectly suited to modern productions, from trap to electronica, alternative rock to commercial pop. It is the choice of those seeking analog character, without compromise.
