Earthworks SR25 Gen 2 Small-diaphragm Condenser Cymbal Microphone User Manual

Introduction

The Earthworks SR25 Gen 2 is a small-diaphragm condenser microphone designed for capturing cymbals, hi-hats, and as a drum overhead. This microphone is engineered to provide exceptional sound quality with high SPL handling, excellent gain before feedback, and a precise supercardioid polar pattern. The Gen 2 model features upgraded active internal electronics for improved phantom power efficiency and protection against hot-swapping incidents, delivering enhanced clarity and presence.

Operating Instructions

• Placement: For cymbal and hi-hat miking, position the microphone 6-12 inches above the instrument, aiming towards the bell or edge depending on the desired sound. For drum overheads, position the microphone to capture the overall drum kit sound, typically 3-6 feet above the kit. Experiment with distance and angle to achieve the optimal sound.
• Polar Pattern: The SR25 Gen 2 features a supercardioid polar pattern, which provides excellent off-axis rejection. Aim the microphone directly at the sound source you wish to capture, and be mindful of sounds coming from the sides or rear, which will be attenuated.
• Gain Staging: Adjust the input gain on your audio interface or mixer to achieve a healthy signal level without clipping. The SR25 Gen 2 has high SPL handling, but proper gain staging is crucial for optimal audio quality.
• Monitoring: Always monitor your audio through headphones or studio monitors to ensure proper microphone placement and signal quality.

Maintenance

• Cleaning: Use a soft, dry cloth to wipe down the microphone body. Do not use liquid cleaners or solvents, as they may damage the finish or internal components.
• Storage: When not in use, store the microphone in its provided bag to protect it from dust and physical damage. Avoid storing in environments with extreme temperatures or high humidity.
• Handling: Handle the microphone with care. Avoid dropping it or subjecting it to strong impacts, which can affect its performance.

Troubleshooting

No Sound Output:

• Ensure 48V phantom power is enabled on your audio interface/mixer.
• Check all XLR cable connections for proper seating.
• Verify that the input gain on your audio interface/mixer is turned up.
• Test with a different XLR cable or input channel to rule out faulty equipment.

Distorted or Weak Sound:

• Reduce the input gain if the sound is distorted (clipping).
• Increase the input gain if the sound is too weak.
• Ensure the microphone is aimed directly at the sound source.

Hum or Noise:

• Check for ground loops; try plugging equipment into the same power strip.
• Ensure all cables are properly shielded and in good condition.
• Keep microphone cables away from power cables or other sources of electromagnetic interference.
