From the seller
API 5500 dual-channel, four-band parametric equalizer in excellent cosmetic condition and perfect working order. Includes both the original API product box and the original API outer shipping carton.
The API 5500 is a modern studio classic, bringing the unmistakable sound and musicality of API's legendary 550-series equalizers to a versatile stereo rackmount format.
Built around API's renowned 2520 discrete op-amps and proprietary transformers, the 5500 delivers the punchy lows, articulate midrange, and open, present highs that have made API equalizers a staple of professional recording studios.
Its signature Proportional Q circuitry automatically adjusts bandwidth according to the amount of boost or cut, making it remarkably easy to achieve musical results. The selectable gain ranges and stepped controls also make the 5500 especially useful for stereo bus processing and mastering, where precise channel matching and repeatability are important.
Highlights:
Dual-channel, four-band analog parametric EQ
Authentic API 2520 discrete op-amps
API transformer-balanced circuitry
Classic API Proportional Q equalization
Seven selectable frequencies per band
Selectable gain ranges for precise tonal adjustments
Stepped controls for repeatable settings
Individual channel bypass
Professional rackmount design
Condition:
Excellent cosmetic condition with only minor signs of mounting around the rack ear screw holes, typical of carefully maintained rackmount studio equipment. The faceplate and controls are exceptionally clean, and the unit is fully functional and operates perfectly.
Original Packaging: Includes both the original API product box and the original API outer shipping box, an added benefit for safe transportation and long-term storage.
An outstanding example of a genuine API 5500, complete with its original factory packaging.
