The 560 was originally developed for use with API mixing consoles from the 1960s and 1970s, and since its relaunch, it has been acclaimed for accomplishing tasks no other equalizer can. The unique API sound is delivered with easy operation, high headroom, and precise filtering, all in an incredibly compact package. The zero-click faders allow for quick resets, and the sound itself is unparalleled. From home recording to studio recording, this ""old but new"" equalizer unit faithfully recreates the original 560. Modern technology has significantly improved the sonic characteristics, especially around ±4 dB. Featuring API's signature all-discrete circuitry and dedicated components (including the legendary original 2520 op amp), this unit truly combines past achievements with present technology. The 560 is designed for professional engineers to use in all situations. Every recording console manufactured by API from the 1970s to the 1980s featured this user-friendly graphic equalizer, providing ideal performance in the studio and on the live stage. This reproduction faithfully reflects the original design drawings and incorporates the latest technology. The 560's 10-band controller provides excellent audio sweetening and sound field correction, working in tandem with parametric equalizers. Like other API equalizers, the 560 features a ""proportional Q"" design, allowing for bandwidth widening or narrowing, resulting in finer adjustments than the actual controllers. The boost and cut characteristics remain consistent, making it easy to recreate past settings. The incredible headroom of the original 2520 op-amp delivers superior analog processing. Installed in the 500 Series rack or lunchbox, it reliably performs in demanding professional environments, no matter the situation. The 560's use of the original 2510 and 2520 op-amps ensures exceptional reliability, long life, and stable operation.
