The 535-LA is spec'd like an API. From the balanced input, polarity switch, and 20dB pad on the front end, to the nifty 3-position toggle switch that gives you a choice of transformer output levels, the 535-LA is a superior piece of pro audio kit that can drive long balanced cable runs with vanishingly low distortion. At Sweetwater, API demands respect for their superior engineering, sonics, and build quality. The 535-LA, boasting discrete 2510 and 2520 op amps along with API's proprietary transformers, certainly lives up to the company's stellar reputation that dates back to its first pro audio products in the late 1960s.
