ALT-436C

The ALT-436C by Antelope Audio is an exacting FPGA-powered emulation of the legendary Altec 436C tube compressor — a rare, vintage unit that shaped the sound of countless classic recordings. Featuring Antelope’s proprietary FPGA modelling technology, the ALT-436C captures every circuit nuance of the original hardware in stunning, low-latency real time.

Why the Altec 436C?

• Vintage Tube Compression Character — The Altec 436C’s unique program-dependent gain reduction delivers a natural, musical feel impossible to replicate with modern solid-state designs
• FPGA Accuracy — Unlike CPU-based plugins, Antelope’s FPGA modelling runs on dedicated hardware for zero-latency, sample-accurate emulation
• Harmonic Saturation — The tube circuit’s characteristic harmonic content adds warmth and colour that glues your mix together
• Retro Ballistics — Attack and release behaviour modelled from the original transformer and tube components
• Seamless Integration — Works natively within Antelope’s Galaxy and Zen series interfaces with zero additional latency

Ideal For

Vocals, drum buses, acoustic instruments, and any source that benefits from the warm, gentle compression that defined the golden age of recording.

Requirements

Requires an Antelope Audio interface with FPGA processing (Galaxy 64 Synergy Core, Zen Go, Zen Tour, or compatible). Mac & Windows.
