Golden Age Project PRE-573 MKIII 500 Series Microphone Preamp

Deliver studio-grade warmth and clarity with a single-channel preamplifier designed to recreate the revered sound of classic British analog gear. The Golden Age Project PRE-573 MKIII offers up to 80 dB of gain, allowing you to capture subtle, quiet sources like passive ribbon microphones without sacrificing detail.

Its solid-state design ensures reliable, low-noise performance across a flat frequency response from 20 Hz to 20 kHz (±1 dB), preserving the natural tonal balance of your recordings. The built-in phantom power supports condenser microphones, while the polarity switch enables phase correction to maintain signal integrity in complex setups.

A selectable highpass filter at 45 or 180 Hz removes unwanted low-frequency rumble, improving mix clarity and reducing muddiness. The preamp’s front-panel 1/4″ DI input accepts electric guitars or basses with switchable impedance settings, providing tonal flexibility for active or passive instruments.

The PRE-573 MKIII features both gain and output level controls, allowing you to drive the main gain stage for vintage-style saturation, then adjust output to optimize your signal chain. Its fully floating, transformer-balanced output can drive 600-ohm loads up to approximately +28 dBu, ensuring compatibility with professional studio equipment.

Compact and robust, this preamp fits into a single 500 Series module slot with a depth of 5.8 inches and weighs only 2.5 pounds. It consumes just 125 mA of power, making it an efficient addition to your rack without compromising performance.

Additional features include a soft-start circuit to avoid power surges, a switchable Air EQ that adds a precise 6 dB boost at 30 kHz for enhanced presence, and a simple LED signal/overload indicator to monitor levels visually.

Designed for engineers and producers seeking authentic analog character with modern reliability, the Golden Age Project PRE-573 MKIII is a versatile, affordable solution that brings classic warmth and punch to any recording session.
