We’re looking forward to refurbishing this vintage API 560a in the near future. These 10 fader eq’s bands are an octave apart, which makes it very intuitive to operate. We especially like the variable Q feature that narrows the Q the harder you boost or cut a band. Of course this unit will be tested and calibrated using out Audio Precision APx 525. Stay tuned for those results, this aught to be an interesting one!
Originally conceived for use in API consoles of the ’60s and ’70s, the 560 is a unique device designed to accomplish tasks that no other EQ can. Extremely fast to set and reset using accurate zero detents, the curve shaping potential of the 560 remains unmatched. With a wide range of 500 mounting options, from racks to consoles, the 560 proves an invaluable asset to all critical performance applications.
The 10 precision EQ bands make the 560 ideal for signal sweetening and room tuning. A great companion to a parametric EQ, the 560 utilizes API’s unique “Proportional Q” design introduced during the ’60s. This design intuitively widens the filter bandwidth at lower boost/cut levels and narrows it at higher settings. Additionally, boost and cut characteristics are identical, allowing previous actions to be undone if desired.
