Miniature Condenser Vibration Pickup for Acoustic Instruments

The AKG C 411 PP is a miniature condenser vibration pickup designed for acoustic guitar, mandolin, violin and a wide range of string instruments. Instead of relying on piezo contact microphones, it utilizes an electret condenser capsule in a sealed enclosure, delivering a clear, uncolored sound. Live performers seeking more natural pickup character than under-saddle transducers often turn to this model.

What sets the C 411 PP apart from typical contact pickups

Most contact microphones employ piezo elements that can exaggerate midrange "honk" and restrict frequency range. This pickup leverages a pre-polarized condenser transducer in a sealed enclosure, providing an extended 10 Hz – 18 kHz response. The 18 g body attaches near the bridge with a solvent-free adhesive pad.

Polar pattern and frequency response — capturing the instrument's true voice

Thanks to the figure-8 polar pattern and a 10 Hz – 18 kHz bandwidth, the device translates vibration to signal with clarity. Unlike typical piezo pickups, a wider low end allows body resonance and woody warmth to be captured distinctly.

• Polar Pattern: Figure 8 — captures vibration from both sides of the bridge area
• Frequency Range: 10 Hz – 18 kHz — reaches well below and above standard piezo contact mic territory
• With a sensitivity of 2 mV/Pa, it matches the performance of standard instrument condensers.

Phantom power and XLR connectivity — ready for any stage or studio rig

Powered by 9–52 V phantom power from any mixer or audio interface, this model integrates into existing setups with no need for additional hardware. The included 3 m cable comes fitted with a standard 3-pin XLR connector.

• Operating Voltage: 9 – 52 V phantom power — works with nearly all mixers or audio interfaces
• Connector: 3-pin XLR (MPAV standard) — connects directly to a stage box or interface input
• A fixed 3 m cable allows you to reach a floor mixer or stage box comfortably.

Dimensions, weight and SPL handling — built for live performance

The sealed plastic enclosure shields the transducer from sweat and humidity, while a matte black finish keeps it unobtrusive. At just 18 g, it adds almost no mass to the instrument and can handle dynamic peaks up to 96 dB SPL during energetic performances.

• Pickup Weight: 18 g — barely affects the balance of the instrument, even when placed on the bridge
• Dimensions: 26.7 × 14.2 × 9.7 mm — compact enough for violin or mandolin bridge plates
• The maximum SPL handling of 96 dB (1% THD) / 103 dB (3% THD) suits loud acoustic playing situations.

Who should choose this miniature vibration pickup

Players of acoustic guitar, mandolin, violin, and sound engineers needing a feedback-resistant, transparent pickup for live performance will appreciate its strengths. Soloists benefit from its rejection of room noise and stage bleed, while studio engineers can blend it with a room mic for a richer sound without the "quack" of piezo pickups.

The C 411 PP family — two versions for different setups

This instrument pickup is available in two versions: the PP with a standard MPAV XLR connector, and the L with a mini-XLR for wireless AKG bodypack transmitters. Acoustic musicians now have a feedback-resistant alternative to ambient miking for stage or studio work.
