Warm Audio WA-2A – Tube Optical Compressor

The Warm Audio WA-2A is a single-channel tube optical compressor inspired by the legendary 2A-style leveling amplifiers. Known for smooth, musical gain reduction and warm analog tone, it’s well suited for vocals, bass, acoustic instruments and mix processing—available at Soundium.

Key Features

  • Classic tube–optical circuit: Uses a T4B-style optical attenuator for naturally smooth compression.
  • CineMag input and output transformers: Provide transformer-balanced warmth and enhanced harmonic depth.

  • Premium tube stage: Equipped with 12AX7, 12BH7 and 6AQ5/6P1 tubes for rich analog character.
  • Stereo link capability: Combine two units for linked stereo operation on mix-bus or stereo sources.

Customer Benefits

The WA-2A delivers the smooth, musical compression associated with classic optical designs. Its tube stage adds warmth and presence, making vocals fuller, bass more controlled and acoustic instruments more refined. With a simple interface and transformer-balanced signal path, it integrates easily into any studio workflow—available at Soundium.
