What are Drum Overheads?
Drum overheads are microphones placed above the drum kit to capture the overall sound of the drums and cymbals, providing a balanced and natural representation of the entire kit. They create a stereo image, adding depth and width to the drum sound in both live sound and studio settings.
Typically positioned above the cymbals or drummer’s head, overhead drum mics pick up a wide frequency response, capturing the attack and decay of cymbals and drums. Their placement balances cymbal mics with close mics like snare mic, kick drum microphone, and tom microphones, forming a complete drum miking solution.
Small diaphragm condenser microphones are commonly used for overheads due to their superior transient response and extended frequency response, while large diaphragm condenser mics offer a warmer, fuller sound. Ribbon mics provide a smooth, natural sound with unique character. Overhead mics often require phantom power to operate and come with various directional patterns, such as cardioid pickup pattern for focused sound capture or omnidirectional microphone for ambient sound.
Using a matched stereo pair of overhead microphones ensures phase coherence and a clear stereo image. Proper mic clips and stands maintain consistent placement, minimizing phase issues and unwanted mic movement. Sound engineers adjust overhead mic height and angle to manage input signal and avoid capturing too much cymbals, which can overpower the drum sound.
In live sound, overhead drum mics capture the natural kit sound and room acoustics, often supplemented by room mics for added ambience. Overall, drum overhead mics are essential for capturing an open, clear drum sound and accurate representation of acoustic instruments like the drum set and cymbals.
Types of Overhead Drum Mics
Overhead drum microphones come in various types, each offering distinct characteristics suited to different recording and live sound scenarios. Understanding these types helps in choosing the right microphone to capture the best drum sound.
Small Diaphragm Condenser Microphones
Small diaphragm condenser microphones are the most popular choice for drum overheads. Their compact size and light diaphragm allow for excellent transient response, capturing the quick attack and decay of drums and cymbals with precision. They typically provide a detailed and accurate representation of the drum kit, making them ideal for capturing cymbal shimmer and the overall kit’s articulation. Models like the Neumann KM184 and Rode NT5 are well-known examples in this category.
Large Diaphragm Condenser Microphones
Large diaphragm condenser microphones offer a warmer, fuller sound compared to their small diaphragm counterparts. While they may not have quite the same transient accuracy, they provide a rich tonal quality that some engineers prefer for drum overheads, especially in studio settings. They are versatile and often used for vocals and other instruments, making them a valuable addition to a microphone collection. The AKG C414 and Neumann TLM 103 fall into this category.
Ribbon Microphones
Ribbon microphones provide a smooth, natural sound with a characteristic warmth and softness in the high frequencies. They are prized for their ability to tame harsh cymbal sounds and add a vintage character to drum recordings. However, ribbon mics are more delicate and require careful handling. They are often used in professional studios where their unique tonal qualities can be fully appreciated. Popular ribbon microphones for overhead use include the Royer R121 and Beyerdynamic M160.
Dynamic Microphones
Though less common for overhead applications, dynamic microphones can be used when durability and high SPL handling are priorities, such as in live sound environments. They generally have slower transient response and less sensitivity, which might result in less detailed cymbal capture. However, their robustness makes them suitable for situations where condenser or ribbon microphones might be at risk. The Shure SM57, while typically a close mic, can sometimes be used in overhead positions in rugged live settings.
Polar Patterns and Their Impact
Overhead microphones come with different polar patterns that influence how they capture sound. Cardioid patterns are most common, focusing on sound from the front and minimizing bleed from other sources. Omnidirectional microphones capture sound equally from all directions, providing a natural room ambiance but potentially more bleed. Figure-eight or bi-directional patterns pick up sound from the front and back, useful in specific stereo techniques but can introduce phase challenges.
Phantom Power Requirement
Most condenser and ribbon microphones require phantom power to operate, supplied by the mixing console or audio interface. It is essential to ensure your equipment can provide the necessary power for these microphones.

Superior Transient Response
Small diaphragm condenser microphones are favored for overhead use because they have a better transient response. This means they can accurately capture the quick attacks of drum hits and cymbal crashes, preserving the natural dynamics of the performance.
Polar Patterns and Sound Isolation
The choice of polar pattern, such as cardioid, omnidirectional, or figure-eight, greatly affects how the overhead mic captures sound. Cardioid patterns are common for isolating the drum kit and reducing bleed from other instruments, while omnidirectional patterns capture a more ambient, natural sound. Figure-eight patterns are sometimes used in specialized stereo techniques.
Phantom Power Requirement
Most overhead condenser microphones require phantom power to operate. This is usually supplied by the mixing console or audio interface.
Handling High Sound Pressure Levels (SPL)
Drums can produce very loud sounds, especially cymbals and snare hits. Overhead mics designed for drum use can handle high SPLs without distortion, ensuring clean recordings even at high volumes.
Matched Stereo Pairs for Stereo Imaging
Using a matched pair of overhead drum mics is essential for achieving a clear and coherent stereo image. Matched pairs ensure consistent frequency response and phase alignment between the two microphones.
Durability and Mounting Stability
Quality mic clips and stands are important to maintain stable and consistent placement during recording or live performances. This helps avoid phase issues and unwanted mic movement.
Versatility Across Instruments
Many overhead drum mics are versatile enough to be used on other acoustic instruments such as acoustic guitars, guitar amps, and brass instruments, making them valuable additions to any microphone collection.
These features combine to provide sound engineers with the tools needed to capture the full energy and nuance of a drum kit, whether in a studio setting or live sound environment.
