Based on the 1967 classic, the API 560 10-Band graphic equalizer features precision filtering and high headroom, ideal for signal enhancement and room tuning. The API 560’s curve shaping potential is unmatched, while API’s unique “Proportional Q” design intuitively widens the filter bandwidth at lower boost/cut levels and narrows it at higher settings. And since boost and cut characteristics are identical, previous actions can be easily undone. For precision equalization with unmatched versatility, turn to the EQ heard on top recordings for decades: the API 560.
