Used AKG C480 B range

The AKG C480 B is a reference modular condenser microphone pre-amplifier designed for use with AKG's ultralinear series capsules. Its electronic circuitry and transformerless output stage deliver linear transfer characteristics across the full frequency range, with self-noise figures close to the theoretical minimum. A specially designed output stage handles difficult loads, including excessively long cables, without compromising signal quality.

The C480 B is the pre-amp body for AKG's ultralinear series capsules: the CK61, CK62, CK63 and CK69 ULS. The modular design means the capsule and pre-amp are separate components, so buyers should confirm which capsule, if any, is included with a used unit, as listings vary in what is offered.

The C480 B includes a two-step high-pass filter and two switchable gain stages providing either -10 dB or +6 dB. It also features a switchable attenuation pad. These controls give engineers flexibility when working in different acoustic environments or with signal chains that require level adjustment at the microphone stage.

The C480 B is made by AKG Acoustics, an Austrian audio company with a long history in microphone and headphone design for studio, broadcast and live sound applications. Within the AKG line, the C480 B sits in the reference modular category, described as one of the quietest microphone amps the brand has built, and serves as the pre-amp platform for the ultralinear capsule series.

Verify that the self-cleaning contacts are in good condition and that the transformerless output stage functions correctly, as these are central to the unit's performance. Confirm whether a ULS capsule is included, since the pre-amp and capsule are separate. Check that any switchable pad, bass-cut filter and gain stages respond correctly. Each 10K Used listing carries a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide/.
