DPA Microphones ST4011A Stereo Pair Mic
- World-wide cardioid reference mic
- Handles very high sound pressure levels
- Carefully matched within ±1 dB
- PeliTM Case transportation and protection
4011A cardioids are exceptionally linear in their frequency response – also off axis, giving you the natural experience. They handle extremely high SPL and will therefore allow for close placement and are often used for piano recordings with a placement closer to the hammers or as overheads for drums.
The DPA ST4011A is a complete DPA 4011A Stereo Pair with two carefully factory-matched first order cardioid microphones. Even though the standard tolerances on DPA Reference Standards are extremely low, a stereo match is even closer.
The specially selected DPA 4011A microphones are matched within ±1 dB on both frequency response and sensitivity.
The foam design in the heavy-duty transportation box allows for fast and easy exchange of microphone/accessory inlay.
Included in this kit
Two carefully matched 4011A cardioid microphones, sturdy PeliTM case, holders, and windscreens.
Accessories
You may be interested in combining the ST4011A with:
SBS0400 Modular Stereo Boom w. Shock Mounts
The lightweight SBS0400 stereo boom addresses the need for quick and flexible ways to switch between stereo principles like AB, XY and ORTF. A central base with rotary joint allows the microphones to be angled equally. SBS0400 has hooks for suspending the boom in wires. The standard length is 40 cm (1.3 ft) but the boom can be further extended. Includes two SM1500 shock mounts (also available as SB0400 without shock mounts).
UA0836 Stereo Boom
The legendary, precision handcrafted DPA stereo boom for accurate and repeatable positioning. Has distance markings in centimeters and typical angle offset markings on holder bases. Can be stand mounted or ceiling suspended. Length: 54 cm. Also available as UA0837 without holders.
SM1500 Shock Mount, Modular
The SM1500 is a modular double pole construction on an adjustable mic stand base. Use this mount to decouple vibrations to your microphone.
TIP: Combined with the MB4000 Magnet Base, the SM1500 and 4011A make a good solution for on-frame mounting inside the piano with closed lid or on short stick for high isolation.
