T25 Tube Compressor

The API Select T25 is a classic FET feedback-style compressor that brings the coveted warmth and richness of vacuum tube technology to your studio. This 2-channel, 2U rackmount unit combines a discrete transistor gain stage with a tube-based output stage, delivering a unique sonic signature that is both smooth and powerful. As a flagship product in the API Select line, the T25 is designed for discerning engineers looking for a high-end dynamics processor to add character, size, and musicality to their tracks. It excels on vocals, bass, piano, and as a final mastering processor on the mix bus.

The T25's hybrid design offers the best of both worlds: the fast, reliable peak detection of a FET compressor and the harmonically rich, larger-than-life sound of a Class-A tube output stage. Each channel features a classic 4-knob layout with controls for Threshold, Ratio, Attack, and Release. A unique feature is the "D-S" switch, which engages a specialized de-essing circuit for taming sibilance. The unit includes a 12AT7WC and 12BH7 dual-triode vacuum tube per channel, which can be driven to produce subtle warmth or rich saturation. The unit can be used as two independent mono compressors or linked for stereo bus work. Large, illuminated analog VU meters provide a classic visual reference for gain reduction, completing the vintage-inspired experience of this exceptional tube compressor.
