AKG C104 Large-Diaphragm Cardioid Condenser Microphone

A fresh ground-up condenser design from AKG — 22mm electret capsule, transformerless FET circuit, 14dB self-noise, 143dB max SPL, and a C414-inspired recycled-metal body. Professional AKG acoustic engineering made accessible for home studios, podcasts, and content creators.

About This Microphone

The AKG C104 is not a repackaged entry-level design — it is a purpose-built, ground-up condenser microphone developed by AKG's engineering team specifically to bring the acoustic character of the C-Series into a genuinely accessible price range. The 22mm nickel-sputtered electret capsule delivers stable, articulate performance across voice, acoustic instruments, and louder sources alike, backed by a transformerless FET circuit that keeps the noise floor at a clean 14dB(A) — a specification that competes well above this price point. At 143dB max SPL, the C104 handles loud sources that would push many budget condensers into distortion: close-miked guitar cabinets, brass, loud vocalists, and percussion all fall well within its headroom. The body design draws visually from the C414 — the head basket profile and overall silhouette closely mirror AKG's flagship studio mic — and is built from 100% recycled post-industrial metals, making it one of the first microphones designed with sustainability as a structural priority. There are no user-adjustable controls on the C104, which keeps the design clean and the price honest: any low-cut or pad is handled at the interface, preamp, or DAW level. An XLR mic stand adapter that accepts both 5/8" US and 3/8" European threading is included, eliminating the need for a separate adapter.

Key Highlights

• 22mm nickel-sputtered electret condenser capsule — delivers stable, articulate capture across voice and instrument sources
• Optimized transformerless FET circuit — low self-noise and fast transient response without the coloration of transformer-coupled designs
• Self-noise: 14dB(A) — a clean, low noise floor that preserves detail on quiet sources including spoken voice and acoustic guitar
• Max SPL: 143dB — handles loud guitar amps, brass, and percussion without perceptible distortion
• Signal-to-noise ratio: 80dB re 1 Pa — wide dynamic range for capturing everything from whispers to stage-volume sources
• Frequency response: 20Hz – 20kHz — full audio band coverage, no artificial coloration at the top or bottom of the spectrum
• Cardioid polar pattern — natural front-of-mic pickup with excellent rear rejection, appropriate for single-source vocal and instrument tracking
• Sensitivity: 13.5mV/Pa (-37.5 dBV) — appropriate for standard audio interfaces and preamps at moderate to high gain
• Electrical impedance: 200 ohms. Recommended load impedance: 1000 ohms or greater
• Requires 48V phantom power — standard on virtually all audio interfaces, mixers, and preamps
• Side-address design — the AKG logo side faces the sound source
• Proximity effect present — intentional low-frequency enrichment when placed close to the source, usable for warmth and intimacy in vocal recording
• No user-adjustable pad or low-cut filter — filtering performed downstream at interface or DAW
• Body constructed from 100% recycled post-industrial metals and alloys — accessories and packaging are fully recyclable
• C414-inspired visual design with head basket profile closely mirroring AKG's flagship studio microphone
• Includes swivel mic stand adapter accepting 5/8" US and 3/8" European threading
• Weight: 0.83 lbs

Great Fit For

• Home studio vocalists who want a clean, articulate condenser with professional AKG lineage at an entry-level price
• Podcasters, YouTubers, and streamers who need a single-pattern cardioid that delivers polished voice quality without complex setup
• Musicians tracking acoustic guitar, strings, brass, and percussion who need a mic with high SPL headroom and full-range response
• Content creators who want the visual and sonic authority of a large-diaphragm condenser without the investment of a premium-tier microphone
• Home producers building their first microphone collection who want a trusted brand with a known acoustic pedigree
• Educators and interviewers recording in treated rooms or quiet environments where the 14dB noise floor delivers clean, professional results

Sound and Use

Aim the AKG logo side of the C104 at the source — this is the front of the microphone. For vocal recording, AKG recommends placement at 3–8cm from the subject, with consistent distance maintained across a session to keep proximity effect — and therefore low-frequency character — stable. The cardioid pattern rejects sound well from the rear and narrows somewhat in the upper frequencies, which contributes to good rejection of room reflections and off-axis bleed in untreated spaces. For louder sources like guitar amplifiers, the 143dB SPL ceiling means the capsule handles close-miking without running into distortion at levels that would clip many budget condensers. The absence of a switchable pad or filter is genuinely not a limitation in most scenarios: any quality audio interface provides those controls either in hardware or software. The C104 takes phantom power from any standard 48V source — engage it at the interface and the microphone is immediately operational.
