Details
Controls: 60dB gain via 24-position gold-plated stepped attenuator, 48V phantom power switch, 20dB pad, phase reverse, DI input, output transformer select (Discrete/Nickel/Steel)
I/O: API 500-series module; mic in, 1/4" DI input, transformer-isolated output; requires 500-series rack/PSU
Notes: FLAG selectable-transformer feature (Discrete/Nickel/Steel), also available in a special "Hammer Forged" copper/black finish (cosmetic variant, not a separate spec listing here). 500-series single-channel version of the Golden Age Microphone Amp (GAMA) circuit. Multi-channel rack formats (Quad GAMA - 4ch, GAMA-8 - 8ch) previously existed but multiple dealers (Sweetwater, Retro Gear Shop) describe them as out of production / no longer available new as of 2026 - excluded from this catalog as discontinued; only the 500-series Mono GAMA was confirmed as currently in production. Price basis: Sweetwater listing $1,240; other dealers show lower figures (~$820-980), so treat as approximate.
