DISC API 560 Discrete 10 Band Graphic EQ

The API 560 Discrete 10 Band Graphic EQ was originally developed for API consoles in the '60s and '70s. Not only does the 560 provide that classic sound and design from API you'd expect in previous units, but it also feature an improved resolution at +/ -4dB. Based on the original 1969 API 560 EQ, this updated version of the classic unit offers consistent analog performance even when using the EQ curves. The low impedance loads result in better low frequency reproduction and tighter imaging, giving you that punchy low-end response API is known for. With 10 precision EQ bands, the 560 is ideal for signal and room tuning. Classic design and quality components make this unit perfect for any sound engineer looking to expand their console unit.

Classic Re-Issue

The 560 was originally developed for use in API Consoles in the 60s and 70s. This re-issue delivers all the features which made the original a keystone in many studios but introduces an improved resolution at +/-4dB. This mixture of new and old makes this re-issue ideal for studio engineers who appreciate the vintage equalization methods but still need the punchy and unique sonic qualities that API are known for.

''Proportional Q'' Control

Saul Walker (The founder of API) designed the ''Proportional Q'' control in the '60s, allowing for the widening of the filter bandwidth at minimal settings whilst narrowing it at higher settings, without the need for additional bandwidth controls. This feature helps to minimise the phase-shift sound found in many equalizer units.

The API 500 Series

The API 500 Series focuses on high sound quality and longevity at an affordable price range. Considering most studio rigs undergo a large amount of swapping and changing between equipment, the API 500 series is designed to last, from its high quality components down to its rugged and durable design.
