AKG C 480 B
A 48-volt-only preamp body that turned AKG's modular ULS capsules into a system. It picked up a reputation for clean, high-headroom capture along the way.
Overview
The C 480 B is the preamp half of AKG's Ultra-Linear Series modular condenser system. You screw a small-diaphragm capsule onto it; it isn't a complete microphone on its own. AKG's own product literature spells out how it differs from the earlier C 460 B: the C 480 B is a 48-volt-only unit built specifically for the ULS series of capsules. There is no battery compartment and no other powering option. You feed it 48 volts and it does its job.
According to the manufacturer's documentation, that job is increased sensitivity, a high overload point, low self noise, and extended frequency response compared to what came before. Those phrases are marketing-adjacent, but the design choices behind them are concrete. A built-in switch lets the user increase preamp gain by +6 dB or preattenuate by 10 dB, which helps when pairing a hot capsule with a quiet source, or a loud one with a sensitive input. There's also a built-in 12 dB/octave bass cut filter, switchable between 70 Hz and 150 Hz. For close-miking a boomy acoustic guitar or a vocalist with a heavy low end, that filter is the difference between a usable track and one you fight in the mix.
The capsule system is where the C 480 B gets its flexibility. AKG's literature describes the CK 69-ULS, a two-part interference tube shotgun capsule, as a natural companion. The full-length tube makes a long shotgun for medium-distance outdoor work or front-of-stage indoor capture at roughly 20 to 24 feet. Unscrew the front half and you get a short shotgun suited to film, TV, or video close-ups, or front-of-stage miking from 10 to 17 feet. The same preamp body that hosts a cardioid small-diaphragm capsule becomes a shotgun with a different screw-on head. That modularity was the whole point of the ULS line.
Mix (October 1997, p.185) put the C 480 B head-to-head against the C 460 B and found the newer body offered a deeper, bigger bottom and more detailed highs. The reviewer noted that while the 460's transient response was already excellent, the 480's was slightly better and rivaled the best microphones on the market at the time. That bidirectional extension of frequency response, the review continued, gave the 480 a better-balanced overall tonality — the 460 sounding a little bright by comparison. That's a meaningful distinction for anyone choosing between the two bodies today: the 460 has its partisans precisely because of that brightness, but the 480 is the more neutral tool.
The physical package, as described in the same Mix field test (October 1997, p.183), arrived in a black, hard plastic, foam-lined case. AKG had switched to that style a few years earlier, replacing its former cardboard storage boxes. An SA 40 swiveling mic stand adapter came with the preamp, but the W32 foam windscreen that was standard issue with the C 460 B combo was absent. The reviewer flagged this as a practical annoyance. The CK61 capsules are somewhat more susceptible to air turbulence than most other small-diaphragm capsules, so a W32, purchasable separately for $9.40, is worth having for every C 480 B/CK61 pairing, especially when close-miking heavy-breathing acoustic guitarists. The foam inserts in the storage case also drew a complaint: you can't store the 480 with a capsule mounted.
Electronic Musician reported a round of AKG price reductions that brought the C 480 B's retail price down to $590 from $819. That's a substantial cut, and at the original figure it competed in a different bracket than it did after the reduction. The same announcement noted reduced pricing across AKG's Blue Line products, including the C 391B combination system and the CK 91, CK 92, and CK 93 capsules.
The C 480 B was on the job in a demanding live classical production with film and broadcast elements. That's a working inventory, not a showcase. The same article noted the C 480 B in a remote recording rig as well, which fits: a preamp body that takes multiple capsules and runs on standard 48-volt phantom is the kind of thing you pack when you don't know what you'll face.
Collectors and working engineers tend to value the C 480 B for the same reasons. The 48-volt-only design is simpler than the C 460 B's more flexible powering, the switchable pad and filter make it adaptable, and the ULS capsule ecosystem means one body can serve several roles. The trade-offs are real. You need 48-volt phantom power, always, and the body is only as useful as the capsules you own. The missing W32 windscreen and the case-insert limitation are minor irritations rather than dealbreakers. Prices on the used market reflect the microphone's status as a professional tool rather than a collector's trophy.
