A boundary microphone, also known as a pressure zone microphone, consists of several tiny cardioid or omnidirectional condenser mic capsules that are flush or adjacent to a boundary (such as a wall, desk, or floor). The capsule(s) may occasionally be housed in a flat plate. The association provides a somewhat phase-coherent output signal with a directional half-space pickup pattern.
By placing the boundary microphone inside the piano lid, the instrument’s combination of strong percussive transients and delicate undertones can be captured more effectively than with other microphone selections. On hockey boards, boundary mics are employed for body scan sound findings.
A boundary microphone prevents phase interference between direct and mirrored sound when used to record a soloist or small musical ensemble along with the room acoustics (such as reverberation), producing a pure sound with a flatter frequency response than would be obtained with a stand-mounted microphone at the same distance.
Boundary microphones are typically less expensive than other microphones, but there are still a variety of price points that differ depending on the number of capsules and the presence or absence of additional features like on-off switches, wireless capabilities, and levers to reposition the capsule.
Shure BETA 91A Half-Cardioid Condenser Kick-Drum Microphone
- Uniform half-cardioid polar pattern for maximum gain-before-feedback and rejection of off-axis sound
- Precision-engineered low-profile design features integrated preamplifier and XLR connector to maximize setup efficiency while minimizing stage clutter
- Frequency response tailored for kick drum/low frequency applications with a wide dynamic range for use in high SPL environments
Kick drums can be used with the Shure BETA91A in addition to other common low-frequency activities like piano. Beta 91A, which has a modern microphone capsule, an integrated preamplifier, and an XLR connection, provides a strong low-frequency response and is especially well-suited for bass frequency functions.
Even at extremely high sound pressure levels, the Beta 91A delivers studio-quality sound with enhanced attack and punch (SPL). Due to its ability to capture the punch and assault of low-frequency instruments like kick (bass) drums, the Shure Beta 91A boundary microphone can also be used as a kick drum mic. It has a broad frequency response that is well suited to capture a variety of audio cues including organ and piano. Additionally, the flat, boundary design makes it simple to attach inside a bass drum and helps to produce a powerful, strong low-end response. The Beta 91A is suitable for both sound reinforcement and recording.
The response of the Beta 91A is optimized for bass frequencies, making it excellent at selecting all low-frequency-intensive instruments. Because of its built-in preamp and ability to handle loud SPLs, the Beta 91A is a very practical condenser that can be used everywhere (even with the loudest live drummers).

The ADX60 is a professional pre-polarized condenser microphone intended for stage, studio, and broadcast use. The ADX60 is incredibly sensitive and capable of handling room and area miking for a variety of applications, including conferences, performances, theater, and acoustic instruments.
The ADX60 is made to focus on a specific area and has an evenly regulated cardioid polar pattern. The cord and phantom energy adaptor for this microphone, which operates on a 9 to 52 V phantom power supply, are included. Off-axis residual noise and vibration are successfully reduced by the cardioid polar pattern. The ADX60 boundary condenser microphone is portable, reliable, and constructed with a high-performance 12 mm capsule, a metal mesh grille, and a mini-XLR connector that takes up little space. The low-profile design works well for attaching instruments on desk surfaces or in kick drums and pianos.
The Audix ADX-60 is a versatile cardioid boundary microphone made for recording instruments and ambient noise. The frequency and sensitivity characteristics of the microphone are more than suitable for recording meetings, conferences, and interviews as well as piano, kick drum, and other sounds. The cardioid polar pattern reduces any lingering surface-born noise that is off-axis.
MXL-AC404 USB Conference Microphone
- Outstanding sound quality even in noisy environments
- Turn any location into a conference room
- Built-in headphone/speaker monitoring jack
This microphone is made to be used for video calls and web chats as well as as a conference mic. It can gather sound even in the noisiest environments and is appropriate for all types of conferencing services. Therefore, this mic is appropriate for group discussions in crowded areas. This makes it especially useful for online conferences and group discussions.
It’s actually made to lay flat on a surface and mimics a computer mouse in many ways. It is a tiny mic with a sturdy metal construction and dimensions of 4.3 by 2.95 by 2 inches. It doesn’t even weigh a pound. A red LED light inside the metal grille illuminates while the microphone is active. It is simple to set up because it is a basic microphone. A USB port for connecting to a computer and a headphone or monitoring jack socket are located on the end of the microphone. Both USB versions 1.0 and 2.0 are compatible.
It includes three boundary design capsules that offer a 180-degree spontaneous pattern. It will give you a roughly 25-foot radius. It delivers a sample rate of 44.1 kHz to 48 kHz and has a frequency response of 40 Hz to 16 kHz. The frequency is very versatile and works well for voice. Any area can be converted into a conference room with the use of a well-made, simple-to-use microphone that is stable on any surface. Its price range is appealing.

- Half super-cardioid polar pattern150 ohms impedance22 mV/Pa sensitivity
- Great for: Theater Large-group performances Lecterns Happenings
This AKG microphone is no exception to their reputation for high-quality construction. Its steel body and grille are resistant to drops and can withstand knocks. It weighs 1.5 pounds and has dimensions of 9.7 x 4.9 x 2.8 inches. The style is made to let the mic to rest on a flat surface, such a table. Users may be positioned all around it in this position.
This modified electric condenser microphone makes use of PCC technology. That will lessen any unnecessary noise. It has an impedance of 150 ohms and a wide frequency response of 40Hz to 18kHz. Additionally, because of its half super-cardioid pattern, it is a fantastic option for presenters at lecterns. A “bass-tilt” control can be used to cut down on any unwelcome low-frequency noise. Since the PCC160 is a condenser microphone, phantom power is necessary. A fifteen-foot cable is part of it.
This microphone can be utilized in a range of settings, including conference calls, lectures, and even as a stage floor mic. It performs superbly wherever it is utilized, ranking it among the best on our list. High-level users should utilize this high-quality mic because of its expense.
