diy u87 as good as original

In the world of audio recording, few microphones hold the same legendary status as the Neumann U87. Known for its warm sound, versatility, and exceptional clarity, the U87 has been a staple in professional studios for decades. However, its high price tag can be a barrier for many aspiring musicians and engineers. This has led to a growing interest in DIY alternatives that promise to replicate the U87's sound quality at a fraction of the cost. In this article, we will explore the feasibility of creating a DIY U87 that is as good as the original, discussing the components, construction techniques, and sound characteristics involved in this fascinating project.

Understanding the Neumann U87 Microphone

The Neumann U87 has a storied history, first introduced in 1967. It has since become a go-to choice for vocal recordings, capturing the nuances of human voice with stunning fidelity. The microphone features a large diaphragm condenser design and offers selectable polar patterns, including cardioid, omnidirectional, and figure-eight, making it versatile for various recording situations.

Key Features of the U87

• Large Diaphragm: Provides a rich and detailed sound.
• Selectable Polar Patterns: Allows for flexibility in different recording environments.
• Low Self-Noise: Ideal for capturing quiet sounds without interference.
• High SPL Handling: Can manage loud sound sources without distortion.

Why Consider a DIY U87?

Building a DIY U87 can be an exciting and rewarding project for audio enthusiasts. Here are some compelling reasons why you might consider embarking on this venture:

Cost-Effectiveness

The original U87 can cost over $3,000, which is simply out of reach for many. A DIY version can be assembled for a fraction of that cost, making high-quality recording accessible to a wider audience.

Hands-On Experience

Building your own microphone allows you to understand the inner workings of audio equipment better. This knowledge can be invaluable for troubleshooting and maintaining your gear.

Customization

A DIY U87 gives you the opportunity to customize components to suit your specific needs or preferences, potentially resulting in a unique sound that fits your style.

Components Needed for a DIY U87

To replicate the U87, you will need several key components. Here’s a list of what you will need and their significance:

Microphone Capsule

The heart of any microphone is its capsule. For a DIY U87, you will want a high-quality large diaphragm condenser capsule. Many builders recommend capsules from brands like Cymbals Only or Mic Supply that closely match the original U87 specifications.

Transformer

The U87 uses a transformer to balance the output signal. You can find high-quality transformers specifically designed for DIY microphone projects that will help maintain the integrity of your sound.

Preamp Circuitry

The preamp is crucial for amplifying the microphone signal. You can either build your own or purchase a preamp board designed for U87 clones. Be sure to select components that have low noise and high gain.

Body and Housing

The physical body of the microphone affects not only durability but also the overall sound. You can use metal or high-density plastic for the housing, ensuring that it is sturdy enough to withstand regular use.

Power Supply

Like most condenser microphones, a DIY U87 will require phantom power. You can either use a standalone phantom power supply or integrate it into your preamp circuitry.

Step-by-Step Guide to Building Your DIY U87

Now that you have all the components, let’s break down the steps to assemble your DIY U87.

Step 1: Prepare Your Workspace

Start by setting up a clean and organized workspace. Ensure you have all your tools and components readily available. A soldering iron, wire cutters, and a multimeter will be essential for this project.

Step 2: Assemble the Capsule

Begin by carefully mounting the microphone capsule into the housing. Pay close attention to the orientation, as this will affect the polar pattern and overall sound quality. Use appropriate mounting techniques to minimize vibrations.

Step 3: Install the Transformer

Next, solder the transformer to the output of the capsule. This step is crucial, as it will help balance the signal and reduce noise. Make sure to follow the wiring diagrams provided with your transformer to ensure proper connections.

Step 4: Build the Preamp Circuit

Using your preamp board, carefully solder the necessary components in place. This may include resistors, capacitors, and any additional circuitry required for your specific design. Be sure to double-check your work to avoid any shorts or errors.

Step 5: Connect the Power Supply

Integrate your phantom power supply into the circuit, ensuring that it is correctly wired to provide the necessary voltage to the microphone. If you are using an external power supply, make sure to test it before final assembly.

Step 6: Final Assembly

Once all components are assembled and tested, carefully fit everything into the microphone housing. Secure all parts firmly, ensuring that there is no movement that could affect the sound quality.

Step 7: Testing Your DIY U87

After assembly, it’s time to test your DIY U87. Connect it to your audio interface or mixer and check for sound quality, clarity, and noise levels. Make any necessary adjustments to the preamp or connections as needed.

Comparing DIY U87 to the Original

Once you have completed your DIY U87, it’s essential to compare its sound quality to the original Neumann U87. Here are some factors to consider:

Sound Quality

While a well-built DIY U87 can come close to the original in terms of sound, there may be subtle differences. The original U87 has been fine-tuned over decades, and its components are optimized for the best performance. However, many users report that a DIY version can hold its own in various recording scenarios.

Durability and Build Quality

The original U87 is renowned for its robust build quality. A DIY version, depending on the materials used, may not reach the same level of durability. It’s essential to invest in quality components to ensure longevity.

Price vs. Performance

Ultimately, the decision to build a DIY U87 versus purchasing the original comes down to budget and performance needs. If you’re looking for a high-quality microphone without breaking the bank, a well-constructed DIY U87 can be an excellent alternative.

Common Questions About DIY U87

Is it legal to build a DIY U87?

Yes, building a DIY U87 for personal use is legal. However, selling clones or replicas may infringe on Neumann's trademarks, so it’s essential to use your DIY microphone for personal projects only.

How much does it cost to build a DIY U87?

The total cost can vary based on the components you choose, but many builders report spending between $300 to $700, significantly less than the original.

Are there any kits available for building a DIY U87?

Yes, several companies offer DIY kits that include all the necessary components and instructions for building a U87 clone. These kits can simplify the process for beginners.

Conclusion

Building a DIY U87 can be a fulfilling project that allows you to create a high-quality microphone without the hefty price tag of the original. By understanding the components and following the assembly steps, you can achieve a sound that rivals the legendary Neumann U87. Whether you’re an aspiring musician, an audio engineer, or a DIY enthusiast, this project offers a unique opportunity to explore the world of professional audio recording.
