Classic Diode Bridge Design with Vintage Electronics
The heart of the Golden Age Project Comp-554 MK2 lies in its vintage-style diode bridge design, which provides the same musical compression and character heard in some of the most iconic studio gear. By utilizing an all-discrete, Class A signal path with no integrated circuits, the Comp-554 MK2 retains the purity of the original designs, offering a rich, warm sound that is both punchy and smooth. This approach ensures that the compressor delivers classic dynamics control without the added distortion that can come with modern integrated circuits. The absence of ICs also contributes to a more natural, transparent compression that is perfect for a wide variety of musical sources.

Enhanced Control and Flexibility
The Golden Age Project Comp-554 MK2 offers comprehensive control over your compression settings, including threshold, ratio, attack, and recovery. With stepped controls for precise adjustments, you can dial in the perfect amount of compression for any source material. The three selectable sidechain filter frequencies provide additional flexibility, allowing you to fine-tune how the compressor responds to various frequency ranges. Whether you're processing vocals or drums, you’ll be able to shape your sound exactly as you want, ensuring that every element sits perfectly in the mix.

Transform Your Sound with the AIR Circuit and Stereo Linking
One of the standout features of the Golden Age Comp-554 MK2 is the AIR circuit, which allows you to add a high-frequency boost at 30kHz. With three selectable EQ settings (Flat, +3dB, +6dB), the AIR circuit enhances your sound with a crisp, airy top end that adds brilliance without harshness. Additionally, the link switch allows you to connect two units for stereo operation, perfect for processing stereo tracks like drum overheads, guitars, or any other stereo source. This ensures consistent compression across both channels, making your stereo mixes tighter and more cohesive.

Built to Last with Robust Features and Connections
The Golden Age Comp-554 MK2 is built with durability and functionality in mind. Featuring transformer-balanced I/O and an external power supply, the unit ensures clean, reliable performance without interference in the audio circuitry. The back-panel switch for 600-ohm termination, the insert connectors for external gear, and the externally balanced sidechain I/O further enhance the flexibility of the unit. Whether you’re using it for a simple mono setup or connecting multiple units for more complex stereo processing, the Comp-554 MK2 is designed to meet the demands of professional studios.
