535-LA

The API 535-LA is a high-quality line amplifier for the 500 series format, expertly designed to amplify, attenuate, and add the classic API analog character to any line-level signal. Inspired by the amplifier sections found in legendary API consoles, the 535-LA is a versatile utility and a powerful creative tool. It's perfect for a variety of tasks, such as boosting low-level signals from vintage synthesizers, attenuating hot signals before they hit your converters, or simply running tracks through its discrete circuitry to impart warmth, punch, and harmonic richness. It effectively acts as a "tone box" and a precise level-matching device in one.

The 535-LA is built around the classic API 2510 and 2520 discrete op-amps and features a custom API output transformer, ensuring the highest fidelity and the signature sound API is known for. The front panel offers a simple yet powerful set of controls. A large rotary knob provides a gain range from -6dB of attenuation up to +35dB of amplification. This allows for precise level management for any line-level source. The module also includes a 20dB pad for taming exceptionally hot signals and a polarity reverse switch. A standout feature is the inclusion of a balanced input selector, allowing it to be used in various console and rack configurations. A multi-segment LED meter provides clear visual feedback of the output level.
