## Long description

The Warm Audio WA-2A is a 2U rack-mount compressor and gate designed for studio recording, mixing and tracking. It reproduces the characteristic '2A style' optical compression with a frequency response of 15–20,000 Hz and a 10 ms attack time, delivering smooth program-dependent gain reduction suitable for vocals, bass and a variety of instruments. Built in a grey steel housing with 115/230 V (50/60 Hz) operation, the unit is compact (482.6 × 177.8 × 88.9 mm) and weighs 5.443 kg, providing an analog signal path with high-voltage Class-A circuitry, CineMag USA transformers, four vacuum tubes and a Kenetek opto-cell.
Advantages
The WA-2A combines optical compression characteristics with a dedicated gate in a single 2U rack unit, enabling controlled dynamics and cleaner tracking workflows without relying on software. Premium components such as large-core CineMag transformers, a Kenetek opto-cell and four socketed vacuum tubes contribute to an open, rich analog tone and reliable long-term serviceability. Dual mains capability (115/230 V) and a robust steel chassis make it suitable for both studio installation and portable rack setups.
Suitable for
 Vocal tracking and smoothing dynamics
 Bass and instrument control with warm optical compression
 Bus compression for cohesive mixes
 Noise gating during tracking and overdubs
 Analog hardware integration in hybrid studios

How to use
Install the WA-2A into a standard 19" equipment rack and connect the mains supply set to the appropriate voltage for your region. Route the audio through the unit using the console or patchbay; insert the compressor/gate on individual channels, buses or the master path as required. Use the optical compressor section for smooth, program-dependent gain control—adjust attack and gain reduction controls to taste—and engage the gate when reducing background noise during tracking. Tube sockets allow easy tube replacement or voicing changes; always power down and discharge capacitors per the manufacturer instructions before servicing tubes.
Usage recommendations
For vocal work, set moderate compression to preserve transients while smoothing peaks; for bass and low-frequency sources, use slower attack settings to retain punch. When using the gate during overdubs, adjust threshold carefully to avoid cutting desired decay. Regularly check tube condition and maintain proper ventilation to ensure stable Class-A operation and consistent tonal character.
