The 535-LA is a 500 series module based on API's 325 booster console cards. It can be used to amplify or attenuate incoming and outgoing signals while providing the brand's signature warmth and tone.
The 535 excels at adding warmth to a variety of signals, like a stereo mix, digital sources or keyboard rigs. Audio playback devices, mic preamps, or audio processing devices that do not have their own level control will also benefit from the added tone and control of the 535-LA.
The 535-LA also includes a balanced input, a polarity switch, a 20dB pad for incoming signal attenuation and a three position toggle switch, which allows for different output gain levels from the transformer. This is designed to drive long balanced lines with low distortion just as the 325 booster card does. Output gain range is from 6dB to 45dB. The 535 utilizes the discrete 2510 and 2520 Op-Amps along with API's proprietary transformers to create the unique, warm and reliable sound that API users expect. Like all API products, the 535-LA features API's unique 5 year warranty.
