What is a contact microphone and how do I use the C411 L?

The C411 L mounts directly onto an acoustic instrument or surface using the included adhesive compound, capturing vibration as audio rather than airborne sound. It's commonly used for classical instrument recording, adding definition to kick drums, or sensing vibration from pianos, guitars, and percussion to blend with or trigger other tracks.

What gear do I need to use the C411 L?

You'll need a microphone preamp or audio interface with phantom power (9–52 V at 2 mA) and a recommended input impedance of 1000 Ohms. The included 1.5 m cable with mini XLR 3-pin connector plugs directly into any professional mixing console, interface, or preamp.

Is the C411 L suitable for live performance or touring?

No. The C411 L is engineered for studio and home recording only; its contact-microphone design and lack of mounting hardware make it impractical for live sound reinforcement or road use.

What's the frequency response and SPL handling?

The C411 L captures 10–18000 Hz with a transparent, low-coloration response ideal for detailed transient capture. It handles 96 dB SPL at 1% THD and 103 dB at 3% THD, giving sufficient headroom for both delicate and aggressive sources without distortion.

How does the C411 L compare to other miniature condensers?

Unlike larger-format studio condensers, the C411 L is purpose-built as a contact pickup with a figure-of-eight polar pattern, making it far more sensitive to vibration and isolation than large-diaphragm or pencil condensers. It serves a specialized role in drum triggering and instrument-close recording rather than general studio tracking.

Do I pay sales tax on this order?

Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. At a typical 7% rate that is an estimated $10 less at checkout than the same listed price on a marketplace, which collects sales tax as the facilitator in most states. Buyers remain responsible for any use tax their state applies. Free US shipping and 30-day returns are included.

AKG C411 L High-Performance Miniature Condenser Vibration Pickup

The AKG C411 L is a compact vibration pickup designed for precision contact miking of acoustic instruments and resonant surfaces. Its diminutive form factor—measuring just 26.7 mm in height—allows discreet mounting on instruments without visual intrusion while delivering studio-grade condenser performance from a rugged plastic body finished in matte black.

Recording Characteristics & Transducer Design

Built on a pre-polarized condenser transducer with a figure-of-eight polar pattern, this pickup captures vibration with 2 mV/Pa sensitivity across a 10–18000 Hz bandwidth. Maximum SPL handling reaches 96 dB at 1% THD and 103 dB at 3% THD, providing sufficient headroom to track both delicate fingerstyle passages and harder-struck articulations without distortion.

Integration & Connectivity

The C411 L presents 200 Ohms electrical impedance and pairs optimally with preamps or mixers offering 1000 Ohms load impedance. Its mini XLR 3-pin female connector connects via an included 1.5 m cable, while phantom power ranging from 9 to 52 V at 2 mA ensures broad compatibility with professional audio interfaces and mixing consoles.
