NEW LEVEL STUDIO POWER

Expensive-sounding discrete mic preamps and vintage gear emulation

Antelope Audio’s Discrete 4 Microphone Preamp comes with 4 console grade 6-transistor discrete preamps, 121 db dynamic range conversion and rock solid clocking. Discrete 4 features the Antelope Audio premier real-time FPGA FX modeling iconic gear from BAE, Lang, Gyraf Audio and FET.

Discrete 4 includes Accusonic 3D microphone and preamp models, guitar amps, transformer and tube FX, and a huge selection of classic vintage gear, which will soon be accessible in any DAW via the upcoming AFX2DAW Plugin (sold separately).
