DPA DPK4011




DPA DPK4011 Piano Stereo Kit
The DPA DPK4011 Piano Stereo Kit contains two matched 4011ES cardioid condenser microphones with active side cables. The microphones are factory-matched within ±1 dB for frequency response and sensitivity across their entire frequency range. This set was previously called the 3511ES Stereo Kit.
The microphone body is just 35 mm long, allowing discreet placement inside an upright or grand piano with the lid open or closed. The cardioid pattern reduces pickup from other directions. A flat on-axis response and smooth off-axis response help preserve the tonal balance of both the instrument and sound arriving from surrounding sources.
Main Features
- Two 4011ES microphones supplied as a factory-matched stereo pair.
- Active side cables for compact placement and suspended microphone setups.
- Included CXO4000 holder supports XY and ORTF stereo configurations.
- Suspension mounts, clips and two DUA9003 modular gooseneck mounts provide different mounting options.
- Suitable for piano recording, live sound reinforcement and spot miking acoustic instruments or orchestral sections.

Included
- 2 × 4011ES microphone, matched stereo pair.
- 2 × SM4000-C suspension mount for pencil microphones.
- 2 × DUA0041 foam windscreen for pencil microphones with active cables.
- 1 × UA0897 shock mount.
- 1 × CXO4000 compact XY/ORTF stereo holder.
- 2 × MC4001 microphone clip for the MMP-E preamp with active cable.
- 2 × DUA9003 modular gooseneck mount.
- Protective carrying case and calibration chart.
Connection and Use
Connect the two XLR3M outputs to two microphone inputs providing P48 phantom power. The included stereo holder supports XY and ORTF configurations, while the separate mounts allow independent placement. Microphone positions can therefore be adjusted to suit the instrument, room and desired balance between direct and ambient sound.
