Langevin AM-439A Pan Module

The Langevin AM-439A is a vintage combining and mixdown module designed for the 1960s Langevin AM4a mixing console system.

the AM-439A down-mix four stems into left/right master output chains. Like the rest of the classic AM-4 series architecture, it relies on discrete transistor gain blocks and custom-wound Langevin transformers to provide a characteristically punchy, colored, and heavily saturated "Class A" sound

• Stereo Mixdown: The AM-439A was specifically engineered to create a stereo mixdown derived from the console's four main output buses. [1]
• Bus Selection: It features push-button switches that allow the operator to route and select any combination of the four main output buses. [1]
• Panning Controls: The module incorporates four individual pan pots to position the selected signals anywhere across the stereo soundstage. [1]
• Unity Gain Amplification: Equipped with dedicated left and right stereo amplifiers, the unit yields unity gain output when the pan pots are panned fully left or right. [1]
