Common Mic Issues with Cymbals
So, what exactly can go wrong when you're mic'ing cymbals? A lot, actually! Let's break down some of the most common mic issues with cymbals that you might encounter, especially in a large venue like the Toyota Center. Understanding these problems is the first step in fixing them, so let’s get into it.
1. Harsh or Brittle Sound
One of the most frequent complaints is that the cymbals sound harsh or brittle. This can be a real ear-piercer and can ruin the overall mix. The main culprits here are often the microphone type and its placement. Using a microphone that's too bright or placing it too close to the cymbal's edge can accentuate the higher frequencies, resulting in that harsh sound. Think of it like shouting into a microphone – you're going to get a lot of unwanted intensity. In a big room like the Toyota Center, this can be amplified even further by reflections and the room's natural acoustics. Sometimes, the EQ settings on your mixing board can also contribute to this issue, especially if the high frequencies are boosted too much.
2. Lack of Clarity and Definition
On the flip side, you might find that your cymbals sound muddy or lack definition. They might get lost in the mix, sounding like a wash of noise rather than distinct, shimmering tones. This often happens when the microphone is too far away, or the room acoustics are swallowing up the sound. In a large space like the Toyota Center, the sound waves have to travel further to reach the microphone, and they can lose energy and clarity along the way. Additionally, if there are too many open microphones picking up the same cymbal, phase cancellation can occur, which further muddies the sound. Also, the quality of the microphone itself plays a significant role; a low-quality mic might not capture the nuances of the cymbal's sound.
3. Excessive Bleed from Other Instruments
Ah, the dreaded bleed! This is when your cymbal microphones are picking up sounds from other instruments, like the snare drum, toms, or even the vocals. Bleed can make your mix sound cluttered and unprofessional, especially in a live setting. It's a common issue in any recording or live performance situation, but it's particularly challenging in a large venue like the Toyota Center, where sound can bounce around quite a bit. The proximity of the microphones to other instruments is a major factor here, as is the polar pattern of the microphone. An omnidirectional microphone, for example, will pick up sound from all directions, making bleed a certainty. The volume levels of other instruments also play a part – a loud snare drum can easily overpower the cymbals in the microphone.
4. Unwanted Room Noise and Reverberation
Every room has its own unique acoustic signature, and in a large venue like the Toyota Center, that signature can be quite pronounced. Unwanted room noise and reverberation can be a real headache when mic'ing cymbals. The reverberation can make the cymbals sound washy and indistinct, while excessive room noise can introduce unwanted hiss or hum into your recording or live mix. This issue is often exacerbated by the microphone's placement and polar pattern. Placing a microphone too far from the cymbal or using a microphone with a wide polar pattern will pick up more of the room's ambience. The room's acoustics themselves are also a major factor – hard surfaces will reflect sound, increasing reverberation, while soft surfaces will absorb sound, reducing it.
5. Phase Cancellation
Phase cancellation is a tricky issue, but it can seriously degrade your cymbal sound. This happens when two or more microphones are picking up the same sound source, but the sound waves arrive at the microphones at slightly different times. When these out-of-phase signals are combined, they can partially or completely cancel each other out, resulting in a thin, weak, or hollow sound. This is especially common when using multiple microphones on a drum kit, including overhead microphones for the cymbals. The distance between the microphones and the cymbal is the critical factor here. If the distance varies too much between the microphones, phase cancellation is likely to occur. The positioning of the microphones relative to each other also plays a role; microphones that are placed at similar distances from the cymbal but at different angles can still experience phase issues.
Troubleshooting Mic Issues on Cymbals
Alright, we've covered the common problems, now let's get to the good stuff – how to fix them! Troubleshooting mic issues on cymbals is a mix of science and art, but with these tips, you'll be well on your way to capturing the perfect cymbal sound, even in a challenging environment like the Toyota Center.
1. Microphone Selection
The first step in getting a great cymbal sound is choosing the right microphone. Not all microphones are created equal, and some are better suited for capturing the high frequencies and dynamic range of cymbals than others. Here are a few key considerations:
- Condenser Microphones: Generally, condenser microphones are the go-to choice for cymbals. They're more sensitive and can capture the subtle nuances and high frequencies that make cymbals shimmer. Small-diaphragm condensers are particularly popular for their accurate transient response and clear sound.
- Dynamic Microphones: While not as common, dynamic microphones can be used on cymbals, especially if you're going for a more raw or aggressive sound. They're less sensitive than condensers, which can be an advantage in loud environments where bleed is a concern.
- Microphone Polar Patterns: The polar pattern of a microphone determines its sensitivity to sound from different directions. For cymbals, cardioid or hypercardioid patterns are often preferred because they reject sound from the sides and rear, reducing bleed and room noise. Omni-directional microphones, which pick up sound from all directions, are generally not ideal for cymbals unless you're specifically going for a very ambient sound.
Think about the sound you're aiming for and the environment you're working in. A bright, crisp cymbal sound might call for a small-diaphragm condenser with a cardioid pattern, while a more controlled sound in a loud venue might benefit from a dynamic microphone or a hypercardioid condenser.
2. Microphone Placement
Microphone placement is absolutely crucial when it comes to capturing the best cymbal sound. Even the best microphone will sound bad if it's positioned poorly. Here are some tips to get it right:
- Distance from the Cymbal: The distance between the microphone and the cymbal will significantly affect the sound. Closer placement will capture more detail and high frequencies, but it can also sound harsh and pick up more bleed. Further placement will sound more natural and balanced but may lack clarity and definition. A good starting point is about 12-18 inches above the cymbal, but you'll need to experiment to find the sweet spot for your particular setup and cymbals.
- Position Relative to the Cymbal: The position of the microphone relative to the cymbal's surface also matters. Placing the microphone closer to the edge will capture more of the cymbal's sustain and shimmer, while placing it closer to the bell will capture more of the attack and fundamental tone. For a balanced sound, try positioning the microphone about halfway between the edge and the bell. The angle of the microphone is also important; angling it slightly downwards can help reduce bleed and capture a more focused sound.
- Overhead vs. Individual Mics: There are two main approaches to mic'ing cymbals: using overhead microphones to capture the entire drum kit (including the cymbals) or using individual microphones on each cymbal. Overhead microphones provide a more natural and cohesive sound, but they can also pick up more bleed and room noise. Individual microphones offer more control over each cymbal's sound but can result in a less natural overall sound. Often, a combination of both techniques is used: overhead microphones for the overall cymbal sound and individual microphones for specific cymbals that need more attention.
3. Addressing Harshness and Brittleness
If your cymbals sound harsh or brittle, there are several things you can try. Firstly, adjust the microphone placement. Moving the microphone further away from the cymbal or closer to the bell can reduce the high-frequency emphasis. You can also try angling the microphone slightly away from the cymbal's edge. Secondly, consider switching to a different microphone. A microphone with a smoother frequency response or a less sensitive diaphragm might be a better choice. Thirdly, use equalization (EQ) to tame the harsh frequencies. A gentle cut in the high-frequency range (around 6-10 kHz) can often make a big difference. However, be careful not to overdo it, as too much EQ can make the cymbals sound dull. Lastly, check your gain staging. If your microphone preamp is set too high, it can cause distortion and harshness. Make sure your input levels are properly set to avoid clipping.
4. Enhancing Clarity and Definition
If your cymbals lack clarity and definition, try the opposite approach. Move the microphone closer to the cymbal to capture more detail. You can also experiment with microphone placement closer to the edge of the cymbal to emphasize the shimmer and sustain. Consider using a brighter microphone or one with a more pronounced high-frequency response. EQ can also be used to enhance clarity. A gentle boost in the high-midrange (around 2-4 kHz) can help bring out the cymbal's attack and definition. Again, be careful not to overdo it, as too much boost can make the cymbals sound harsh. Check the room acoustics to minimize excessive reverberation. Using acoustic treatment, such as gobos or sound panels, can help absorb reflections and improve clarity.
5. Minimizing Bleed and Room Noise
Reducing bleed and room noise is essential for a clean and professional cymbal sound. Start by using microphones with tight polar patterns, such as cardioid or hypercardioid. These microphones will reject sound from the sides and rear, reducing bleed from other instruments. Position the microphones carefully to minimize bleed. Aim the microphone away from other instruments and towards the cymbal. Use gobos or other acoustic barriers to create separation between instruments. This can be particularly effective in a large venue like the Toyota Center, where sound can bounce around easily. Close-miking techniques can also help reduce bleed. Placing the microphone closer to the cymbal will capture more of the cymbal's sound and less of the surrounding noise. Gate plugins can be used to reduce bleed in post-production. A gate will automatically mute the microphone when the signal level drops below a certain threshold, effectively cutting out bleed during quiet passages.
6. Avoiding Phase Cancellation
Phase cancellation can be tricky to identify and fix, but it's crucial to get right. The key is to minimize the distance differences between microphones. If you're using multiple microphones on a drum kit, try to ensure that they are equidistant from the snare drum or other key sound sources. A good rule of thumb is the 3:1 rule: the distance between microphones should be at least three times the distance from each microphone to its sound source. Use a phase alignment tool to check for and correct phase issues. These tools can invert the polarity of a microphone signal, which can often resolve phase cancellation problems. Experiment with microphone positioning to find the sweet spot where the signals are in phase. Sometimes, simply moving a microphone a few inches can make a big difference.
Specific Tips for the Toyota Center
Working in a large venue like the Toyota Center comes with its own unique challenges. The size of the room, the acoustics, and the potential for noise all need to be considered. Here are some specific tips for mic'ing cymbals at the Toyota Center:
- Acoustic Treatment: The Toyota Center is a large, reverberant space, so acoustic treatment is crucial. Use gobos, sound panels, and other acoustic barriers to minimize reflections and control the room's ambience. Pay particular attention to the area around the drum kit, as this is where most of the cymbal sound originates.
- Microphone Choice: In a large venue, bleed and room noise can be major concerns. Choose microphones with tight polar patterns and good off-axis rejection. Dynamic microphones can be a good choice for louder drummers or situations where bleed is a significant issue.
- Microphone Placement: Experiment with microphone placement to find the best balance between clarity, definition, and bleed. Close-miking techniques can be effective in reducing bleed, but be careful not to sacrifice the natural sound of the cymbals.
- Gain Staging: Proper gain staging is essential in any venue, but it's particularly important in a large room like the Toyota Center. Make sure your input levels are properly set to avoid clipping and distortion. Use a mixing console with high-quality preamps to ensure a clean and transparent sound.
- Monitoring: Accurate monitoring is crucial for making informed decisions about microphone placement and EQ. Use high-quality headphones or in-ear monitors to listen critically to the cymbal sound. If possible, also listen to the mix through the venue's sound system to get a sense of how the cymbals sound in the room.
