چمتو کول

1. خلاصول

Carefully remove the microphone and its accessories from the wooden box. Inspect all components for any signs of damage.

۲. د مایکروفون نصبول

Attach the EA87 shockmount to a suitable microphone stand. Gently insert the U 87 Ai microphone into the shockmount, ensuring it is held firmly but without excessive force. The shockmount helps to isolate the microphone from vibrations transmitted through the stand.

۳. د مایکروفون سره نښلول

Connect the provided XLR cable to the 3-pin XLR connector at the base of the microphone. Connect the other end of the XLR cable to a microphone preamplifier, audio interface, or mixing console that supplies 48V phantom power. Ensure phantom power is turned off on your device before connecting or disconnecting the microphone to prevent potential damage.

1. Polar Patterns

The U 87 Ai offers three selectable polar patterns: omnidirectional, cardioid, and figure-8. These patterns determine the microphone's sensitivity to sound from different directions.

• هر اړخیز: Picks up sound equally from all directions. Ideal for capturing room ambiance or multiple sources.
• د کارډیایډ: Most sensitive to sound from the front, with significant rejection from the rear. Suitable for vocals and isolating individual instruments.
• شکل-۱: Equally sensitive to sound from the front and rear, with rejection from the sides. Useful for recording two vocalists facing each other or for M/S stereo techniques.

The polar pattern switch is located on the front of the microphone body, below the grille.

2. Pre-attenuation Pad (-10dB)

The U 87 Ai features a switchable -10dB pre-attenuation pad. This pad reduces the microphone's output level by 10 decibels, preventing distortion when recording very loud sound sources, such as close-miked drums or guitar amplifiers. Engage this switch when the input signal is too hot for your preampلايف

3. Low-Frequency Roll-off

A switchable low-frequency roll-off (high-pass filter) is integrated into the U 87 Ai. This filter attenuates frequencies below approximately 100 Hz, which can be useful for reducing unwanted rumble, handling noise, or proximity effect when close-miking. The switch for the low-frequency roll-off is typically located near the polar pattern and pad switches.

۲.۴. غوره ځای پر ځای کول

Microphone placement significantly impacts the recorded sound. Experiment with distance and angle relative to the sound source to achieve the desired tonal balance and minimize unwanted room reflections. For vocals, a pop filter is recommended to reduce plosives.

ساتنه او پالنه

• پاکول: Use a soft, dry cloth to wipe the microphone body. Do not use liquid cleaners or solvents, as they can damage the finish or internal components.
• ذخیره کول: When not in use, store the microphone in its original wooden box or a protective case to shield it from dust, moisture, and physical impact.
• سمبالول: Avoid dropping or subjecting the microphone to harsh impacts. The capsule is a delicate component.
• چاپیریال: Operate and store the microphone in a clean, dry environment with stable temperature and humidity.

  • Verify that the input gain on your preamplifier is set appropriately.
• تحریف شوی غږ:
  • If recording loud sources, engage the -10dB pre-attenuation pad on the microphone.

  • Ensure the microphone is not overloaded by excessively loud sound sources.
• Excessive Bass/Rumble:
  • Engage the low-frequency roll-off switch on the microphone.
  • Increase the distance between the microphone and the sound source to reduce proximity effect.
• Intermittent Sound/Noise:
  • Check for faulty cables or connectors.
  • Ensure proper grounding of all audio equipment.
  • Verify that the microphone is not picking up electrical interference from other devices.
