Setting up drum microphones and mixers is a crucial process in achieving high-quality drum recordings. This article provides a comprehensive guide on the equipment needed, microphone placement techniques, connecting to the mixer, and final adjustments. Whether you’re a beginner or an experienced sound engineer, this guide will help you navigate the complexities of drum miking and mixing.
Equipment Needed
Before diving into the setup process, it’s essential to gather all the necessary equipment. Here’s what you’ll need:
1. Microphones
Choosing the right microphones is fundamental to capturing the unique sound of each drum component. Here’s a breakdown of the types of microphones commonly used for drum miking:
Dynamic Microphones
Dynamic mics are robust and well-suited for high sound pressure levels, making them ideal for close-miking drums. They capture the attack and punch of drum sounds effectively. Recommended dynamic mics include:
Kick Drum: The Shure Beta 52A or AKG D112 are excellent choices for miking the kick drum. These mics can handle high SPLs and provide a deep, rich low end.
Snare Drum: The Shure SM57 is a classic choice for the snare drum. It captures the crisp attack and body of the snare while rejecting bleed from other drums.
Condenser Microphones
Condenser mics are sensitive and can capture the nuances of the drum sound, making them ideal for overhead and room miking. Recommendations include:
Overheads: The Rode NT5 or Audio-Technica AT2021 are great for capturing the overall sound of the drum kit, including cymbals and ambient sound.
Room Mics: Use larger diaphragm condensers like the Neumann TLM 103 or AKG C414 to capture room sound and add depth to your recordings.
Specialty Microphones
For specialized miking techniques, consider using:
Lavalier Microphones: For unique sound capture, such as internal miking of the kick drum, a small lavalier mic can be placed inside the drum.
2. Mic Stands and Clips
Having sturdy microphone stands and clips is crucial for accurate microphone positioning. Here’s why:
Stability: Drum kits can be vibrant and loud, causing unstable mic stands to shift or fall. Use heavy-duty stands for overheads and snare mics.
Adjustability: Flexible boom arms on stands allow you to position microphones precisely where you need them.
Clips: Ensure you have the right clips to hold your microphones securely in place. This will prevent unwanted movement during recording.
3. Cables and Connectors
Proper cabling is essential for a clean signal path. Here’s what you need:
XLR Cables: Use high-quality XLR cables for all microphone connections. XLR cables offer balanced connections that minimize noise and interference, crucial in a drum recording environment.
Connectors: Ensure that all your microphones are equipped with XLR connectors to plug into your mixer or audio interface easily.
4. Audio Interface/Mixer
The audio interface or mixer plays a pivotal role in your setup. It allows you to connect multiple microphones, adjust levels, and send the audio to your recording software or amplifier. Here’s what to consider:
Channel Count: Choose a mixer or interface that offers enough channels for all your mics. A typical setup might require 8 to 16 channels, depending on how many drums and cymbals you’re miking.
Preamp Quality: Look for interfaces with high-quality preamps to ensure clear sound without distortion.
Connection to Software: Ensure the interface connects easily to your recording software via USB or other protocols. Popular DAWs (Digital Audio Workstations) include Pro Tools, Logic Pro, and Ableton Live.
Microphone Placement
Proper microphone placement is critical in achieving the best sound from your drum kit. Here are detailed instructions for miking various components:
1. Kick Drum
For the kick drum, you can choose to mic either inside or outside the drum:
Inside the Kick Drum:
Position the mic approximately 2-4 inches from the beater head, angled slightly toward the center of the drum. This placement captures the attack and low-end punch effectively.
Using a dynamic mic like the Shure Beta 52A, you can achieve a strong bass presence.
Outside the Kick Drum:
Place the microphone just outside the resonant head, facing the drum. This position captures more of the drum’s natural resonance and adds warmth.
Experiment with distance to find the sweet spot, usually around 6-12 inches from the resonant head.
2. Snare Drum
To capture the snare drum effectively, consider the following placement:
Position the mic about 1-3 inches above the snare, aimed at the center of the drumhead. This positioning captures both the crack and the body of the snare sound.
Use a dynamic mic like the Shure SM57, which handles the snare’s high transient peaks well.
For added depth, you may also place a second mic underneath the snare, inverted and aimed at the snare wires, to capture the snare’s crispness. This technique is known as a “bottom mic.”
3. Toms
Miking toms effectively requires attention to placement:
Rack Toms:
Place the microphone 1-3 inches above the tom head, angled toward the center. This captures the fullness and attack.
A dynamic mic like the Sennheiser e604 is a popular choice for rack toms due to its compact design and excellent sound quality.
Floor Tom:
Position the mic similarly, about 1-3 inches above the head, but you can also experiment with positioning it at the side of the tom to capture a different tonal quality.
Ensure the mic is secure, as floor toms often produce significant vibrations.
4. Overheads
Overhead microphones capture the overall sound of the drum kit and cymbals:
Position two condenser microphones in a stereo configuration. Common techniques include the XY pattern or the spaced pair method.
For the XY pattern, place the mics about 3-4 feet above the drum kit, angled toward the snare drum. This method provides a clear stereo image and captures the kit’s sound cohesively.
For the spaced pair method, position the mics further apart (around 3-4 feet) above the kit, ensuring they are equidistant from the snare to maintain phase coherence.
5. Room Mics
Room microphones add depth and ambiance to your drum recordings:
Place one or two condenser microphones at a distance from the drum kit, capturing the natural reverb of the room. This adds dimension to the sound.
Ideal placement is about 6-10 feet away, aimed toward the kit but not directly at it to avoid capturing too much direct sound.
Connecting to the Mixer
Once your microphones are in place, it’s time to connect them to your mixer. Follow these steps:
1. Channel Assignment
Identify Each Mic: Label each microphone according to the drum it’s capturing (e.g., Kick, Snare, Tom 1, etc.).
Assign to Channels: Connect each mic to a specific channel on the mixer. For instance, assign the kick drum mic to Channel 1, snare to Channel 2, and so on.
2. Setting Levels
Setting initial levels correctly is essential for a clean recording:
Start with Moderate Levels: Begin with all faders at the middle position (0 dB) and slowly increase the gain for each channel until you achieve a healthy signal without clipping.
Use the Meters: Monitor the LED meters on the mixer to ensure levels are optimal, aiming for a peak level around -6 dB to -3 dB.
3. EQ and Effects
Using the EQ controls on the mixer helps shape the sound of each drum component:
Kick Drum: Boost low frequencies around 60-80 Hz for depth, and cut unwanted mids around 300-500 Hz if necessary.
Snare Drum: Boost around 5 kHz for crispness, and consider a slight dip at around 200 Hz to reduce muddiness.
Toms: Shape toms by boosting frequencies around 80-100 Hz for fullness, and cut around 300 Hz if needed.
Cymbals: For overheads, boost around 10-12 kHz to add brightness while being careful not to introduce harshness.
Applying Effects: Consider adding effects like reverb or compression after setting EQ. Apply these effects judiciously to maintain the natural sound of the drums while enhancing them.
Testing and Adjusting
Once everything is connected, testing and making necessary adjustments are crucial.
1. Phase Checking
Check for Phase Issues: When using multiple microphones, phase issues can arise, causing sound cancellation. To check for phase, listen to each mic in isolation and then together.
Adjust Placement: If you notice a lack of clarity, try slightly repositioning mics (especially overheads and room mics) to resolve phase discrepancies.
2. Listening and Tweaking
Monitor the Sound: Use high-quality monitors or headphones to listen to the mix. Pay attention to the balance of each drum component.
Make Adjustments: If certain drums sound too loud or soft, adjust the gain on the mixer or reposition the microphones for a better sound balance.
Additional Tips
Recording Software
Consider using digital audio workstation (DAW) software that allows for easy monitoring and adjustments during recording. This capability will help you visualize your sound and make real-time changes.
Acoustic Treatment
Using acoustic treatment in your recording space can significantly improve sound quality. Here are some ideas:
Gobos: Use gobos (portable acoustic panels) around the drum kit to reduce unwanted reflections.
Blankets: Hang heavy blankets or curtains in the recording space to absorb sound and reduce echoes.
Practice and Patience
Setting up drum mics and a mixer can be a learning experience. Here are some reminders:
Experiment: Don’t be afraid to try different microphone placements and mixer settings. Each drum kit and room will produce different results.
Be Patient: Quality sound takes time to achieve. The more you practice setting up and adjusting your mics, the better your results will be.
Conclusion
Setting up drum mics and a mixer is a nuanced process that can significantly impact your recording quality. By understanding the equipment needed, mastering microphone placement, and efficiently connecting and adjusting your mixer, you can achieve a professional sound. Remember to take your time, experiment, and continuously refine your techniques. With practice and patience, you will elevate your drum recordings to new heights.
